; GRAY'S SCHOOL AND FIELD BOOK OP BOTANY CONSISTING OF "LESSONS IN BOTANY" AND "FIELD, FOREST, AND GARDEN BOTANY" BOUND IN ONE VOLUME REVISED EDITION PUBLISHERS' PREFACE TO GRAY'S SCHOOL AND FIELD BOOK OF BOTANY. THIS work consists of the "LESSONS IN BOTANY" and the "FIELD, FOREST, AND GARDEN BOTANY," bound together in one complete volume, forming a most popular and comprehensive SCHOOL BOTANY, adapted to beginners and advanced classes, to Agricultural Colleges and Schools, as well as to all other grades in which the science is taught. It is also adapted for use as a handbook to assist in analyzing plants and flowers in field study of botany either by classes or individuals. The book is intended to furnish Botanical Classes and beginners with an easier introduction to the Plants of this country, and a much more compre- hensive work, than the MANUAL. Beginning with the first principles, it progresses by easy stages until the student who is at all diligent is enabled to master the intricacies of the science. It is a Grammar and Dictionai-y of Botany, and comprises the common Herbs, Shrubs, and Trees of the Southern as well as the Northern and Middle States, including the commonly cultivated as well as the native species in fields, gardens, pleasure grounds, or house culture, and even the conservatory plants ordinarily met with.

LESSONS W. P. II PREFACE. THIS volume takes the place of the author's LESSONS IN BOTANY AND VEGETABLE PHYSIOLOGY, published over a quarter of a cen- tury ago. It is constructed on the same lines, and is a kind of new and much revised edition of that successful work. While in some respects more extended, it is also more concise and terse than its predecessor. This should the hetter fit it for its purpose now that competent teachers are common. They may in many cases develop paragraphs into lectures, and fully illustrate points which are barely, but it is hoped clearly, stated. Indeed, even for those without a teacher, it may be that a condensed is better than a diffuse exposition. The book is adapted to the higher schools, " How Plants Grow and Behave " being the " Botany for Young People and Common Schools." It is intended to ground beginners in Structural Botany and the principles of vegetable life, mainly as concerns Flowering or Phanerogamous plants, with which botanical instruction should always begin ; also to be a companion and interpreter to the Man- uals and Floras by which the student threads his flowery way to a clear knowledge of the surrounding vegetable creation. Such a book, like a grammar, must needs abound in technical words, which thus arrayed may seem formidable ; nevertheless, if rightly apprehended, this treatise should teach that the study of bot- any is not the learning of names and terms, but the acquisition of knowledge and ideas. No eifort should be made to com- mit technical terms to memory. Any term used in describing a plant or explaining its structure can be looked up when it is wanted, and that should suffice. On -the other hand, plans of iv PREFACE. structure, types, adaptations, and modifications, once understood, are not readily forgotten ; and they give meaning and interest to the technical terms used in explaining them. In these "Elements" naturally no mention has been made of certain terms and names which recent cryptogam ically-minded botanists, with lack of proportion and just perspective, are en- deavoring to introduce into phanerogamous botany, and which are not needed nor appropriate, even in more advanced works, for the adequate recognition of the ascertained analogies and homologies. As this volume will be the grammar and dictionary to more than one or two Manuals, Floras, etc., the particular directions for pro- cedure which were given in the " First Lessons " are now relegated to those works themselves, which in their new editions will pro- vide the requisite explanations. On the other hand, in view of such extended use, the Glossary at the end of this book has been considerably enlarged. It will be found to include not merely the common terms of botanical description but also many which are unusual or obsolete ; yet any of them may now and then be encoun- tered. Moreover, no small number of the Latin and Greek words which form the whole or part of the commoner specific names are added to this Glossary, some in an Anglicized, others in their Latin form. This may be helpful to students with small Latin and less Greek, in catching the meaning of a botanical name or term. The illustrations in this volume are largely increased in number. They are mostly from the hand of Isaac Sprague. It happens that the title chosen for this book is that of the author's earliest publication, in the year 1836, of which copies are rarely seen ; so that no inconvenience is likely to arise from the present use of the name.

INTRODUCTORY. 1. BOTANY is the name of the science of the vegetable kingdom in general ; that is, of plants. 2. Plants may be studied as to their kinds and relationships. This study is SYSTEMATIC BOTANY. An enumeration of the kinds of vegetables, as far as known, classified according to their various degrees of resemblance or difference, constitutes a general System of plants. A similar account of the vegetables of any particular country or district is called a Mora. 3. Plants may be studied as to their structure and parts. This is STRUCTURAL BOTANY, or ORGANOGRAPHY. The study of the organs or parts of plants in regard to the different forms and different uses which the same kind of organ may assume, the comparison, for instance, of a flower-leaf or a bud-scale with a common leaf, is VEGETABLE MOR- PHOLOGY, or MORPHOLOGICAL BOTANY. The study of the minute structure of the parts, to learn by the microscope what they themselves are formed of, is VEGETABLE ANATOMY, or HISTOLOGY ; in other words, it is Micro- scopical Structural Botany. The study of the actions of plants or of their parts, of the ways in which a plant lives, grows, and acts, is the province .of PHYSIOLOGICAL BOTANY, or VEGETABLE PHYSIOLOGY. 4. This book is to teach the outlines of Structural Botany and of the simpler parts of the physiology of plants, that it may be known how plants are constructed and adapted to their surroundings, and how they live, move, propagate, and have their being in an existence no less real, although more simple, than that of the animal creation which they support. Particularly, this book is to teach the principles of the structure and rela- tionships of plants, the nature and names of their parts and their modifica- tions, and so to prepare for the study of Systematic Botany ; in which the learner may ascertain the name and the place in the system of any or all of the ordinary plants within reach, whether wild or cultivated. And in ascertaining the name of any plant, the student, if rightly taught, will come to know all about its general or particular structure, rank, and relationship to other plants. 10 ELEMENTS OF BOTANY. [SECTION 1, 5 The vegetable kingdom is so vast and various, and the difference is so wide between ordinary trees, shrubs, and herbs on the one hand, and mosses, moulds, and such like on the other, that it is hardly possible to frame an intelligible account of plants as a whole without contradictions or misstatements, or endless and troublesome qualifications. If we say that plants come from seeds, bear flowers, and have roots, stems, and leaves, this is not true of the lower orders. It is best for the beginner, therefore, to treat of the higher orders of plants by themselves, without particular reference to the lower. 6. Let it be understood, accordingly, that there is a higher and a lower series of plants ; namely : PHANEROGAMOUS PLANTS, which come from seed and bear foteert, es- sentially stamens and pistils, through the co-operation of which seed is produced. For shortness, these are commonly called PHANEROGAMS, or Phanogams, or by the equivalent English name of FLOWERING PLANTS.* CRYPTOGAMOUS PLANTS, or CRYPTOGAMS, come from minute bodies, which answer to seeds, but are of much simpler structure, and such plants have not stamens and pistils. Therefore they are called in English FLOWEH.LESS PLANTS. Such are Ferns, Mosses, Alga? or Seaweeds, Fungi, etc. These sorts have each to be studied separately, for each class or order has a plan of its own. 7. But Phanerogamous, or Flowering, Plants are all constructed on one plan, or type. That is, taking almost any ordinary herb, shrub, or tree for a pattern, it will exemplify the whole series : the parts of one plant answer to the parts of any other, with only certain differences in particulars. And the occupation and the delight of the scientific botanist is in tracing out this common plan, in detecting the likenesses under all the diversities, and in noting the meaning of these manifold diversities. So the attentive study of any one plant, from its growth out of the seed to the flowering and fruiting state and the production of seed like to that from which the plant grew, would not only give a correct general idea of the structure, growth, and characteristics of Flowering Plants in general, but also serve as a pat- tern or standard of comparison. Some plants will serve this purpose of a pattern much better than others. A proper pattern will be one that is perfect in the sense of having all the principal parts of a phanerogamous plant, and simple and regular in having these parts free from complications or disguises. The common Flax-plant may very well serve this purpose. Being an annual, it has the advantage of being easily raised and carried in a short time through its circle of existence, from seedling to fruit and seed. ' The name is sometimes Phanerogamous, sometimes Phanogamous (Phanero- gams, or Phanogams), terms of the same meaning etymologically ; the former of preferable form, but the latter shorter. The meaning of such terms is explained in the Glossary. SECTION 2.] A PATTERN PLANT. 11 SECTION II. FLAX AS A PATTERN PLANT. 8. Growth from the Seed. Phanerogamous plants grow from seed, and their flowers are destined to the production of seeds. A seed has a rudimentary plant ready formed iu it, sometimes with the two most essential parts, i. e. stem and leaf, plainly discernible ; sometimes with no obvious distinction of organs until germination begins. This incipient plant is called an EMBRYO. 9. In this section the Flax-plant is taken as a specimen, or type, and the development and history of common plants in general is illustrated by it. In flux-seed the embryo nearly fills the coats, but not quite. There is a small deposit of nourishment between the seed-coat and the embryo : this may for the present be left out of the account. This embryo consists of a pair of leaves, pressed together face to face, and attached to an ex- tremely short stem. (Fig. 2-4.) In this rudimentary condition the real nature of the parts is not at once apparent ; but when the seed grows they promptly reveal their character, as the accompanying figures (Fig. 5-7) show. 10. Before the nature of these parts in the seed was altogether under- stood, technical names were given to them, which are still in use. These initial leaves were named COTYLEDONS. The initial stem on which they stand was called the RADICLE. That was because it gives rise to the first root ; but, as it is really the beginning of the stem, and because it is the stem that produces the root and not the root that produces the stem, it is better to name it the CATJLICLE. Recently it has been named Hypocotyle; which signifies something below the cotyledons, without pronouncing what its nature is. FIG. 1. Pod of Flax. 2. Section lengthwise, showing two of the seeds; one whole, the other cut half away, bringing contained embryo into view. 3. Similar section of a flax-seed more magnified and divided, flatwise; turned round, so that the stem-end (caulicle) of the embryo is below: the whole broad upper part is the inner face of one of the cotyledons; the minute nick at its base is the plumule. 4. Similar section through a seed turned edgewise, showing the thickness of the cotyledons, and the minute plumule between them. i. e. the minute bud on the upper end of the canlicle. 12 A PATTERN PLANT. [SECTION 2. 11. On committing these seeds to moist and warm soil they soon sprout, i. e. germinate. The very short stem-part of the embryo is the first to grow. It lengthens, protrudes its root-end ; this turns downward, if not already pointing in that direction, and while it is lengthening a root forms at its point and grows downward into the ground. This root continues to grow on from its lower end, and thus insinuates itself and penetrates into the soil. The stem meanwhile is adding to its length throughout ; it erects itself, and, seeking the light, brings the seed up out of the ground. The mate- rials for this growth have been supplied by the cotyledons or seed-leaves, still in the seed : it was the store of nour- ishing material they held which gave them their thickish shape, so unlike that of ordinary leaves. Now, relieved of a part of this store of food, which has formed the growth by which they have been raised into the air and light, they appropriate the remain- der to their own growth. In enlarging they open and throw off the seed-husk ; they expand, diverge into a horizontal position, turn green, and thus become a pair of evident leaves, the first foliage of a tiny plant. This seedling, although diminutive and most simple, possesses and puts into use, all the ORGANS of VEGETATION, namely, root, stem, and leaves, each in its proper element, the root in the soil, the stem rising out of it, the leaves in the light and open air. It now draws in moisture and some food-materials from the soil by its root, conveys this through the stem into the leaves, where these materials, along with other crude food which these imbibe from the air, are assimilated into vegetable matter, i. e. into the material for further growth. 12. Further Growth soon proceeds to the formation of new parts, downward in the production of more root, or of branches of the main root, upward in the development of more stem and leaves. That from which a stem with its leaves is continued, or a new stem (i. e. branch) originated, is a BUD. The most conspicuous and familiar buds are those of most shrubs and trees, bearing buds formed in summer or autumn, to grow the following Fid. 5.

Same still older, with more leaves developed, but these singly (one after another), and with joints of stem between them. SECTION 2.] A PATTERN PLANT. 13 spring. But every such point for new growth may equally bear the name. When there is such a bud between the cotyledons in the seed or seedling it is called the PLUMULE. This is conspicuous enough in a beau (Fig. 29.), where the young leaf of the new growth looks like a little plume, whence the name, plumule. In flax-seed this is very minute indeed, but is discernible with a magnifier, and in the seedling it shows itself distinctly (Fig. 5, 6, 7). 13. As it grows it shapes itself into a second pair of leaves, which of course rests on a second joint of stem, although in this instance that remains too short to be well seen. Upon its summit appears the third pair of leaves, soon to be raised upon its proper joint of stem ; the next leaf is single, and is carried up still further upon its supporting joint of stem ; and so on. The root, meanwhile, continues to grow underground, not joint after joint, but continuously, from its lower end ; and commonly it before long multiplies itself by branches, which lengthen by the same continuous growth. But stems are built up by a succession of leaf-bearing growths, such as are strongly marked in a reed or corn- stalk, and less so in such an herb as Flax. The word "joint " is ambigu- ous : it may mean either the portion between successive leaves, or their junction, where the leaves are at- tached. For precision, therefore, the place where the leaf or leaves are borne is called a NODE, and the naked interval between two nodes, an INTERNODE. 14. In this way a simple stem with its garniture of leaves is de- veloped from the seed. But besides this direct continuation, buds may form and develop into lateral rf*jms, that is, into branches, from any node. The proper origin of branches is from the AXIL of a leaf, i. e. the angle between leaf and stem on the upper side ; and branches may again branch, so building up the herb, shrub, or tree. But sooner or later, and without long delay in an annual like Flax, instead of this continuance of mere vegetation, reproduction is prepared for by Fia. 8. Ujjuer part of Flax-plant in blossom. 14 A PATTERN PLANT, [SECTION 2. 15. Blossoming. In Flax the flowers make their appearance at the end of the stein and branches. The growth, which otherwise might con- tinue them farther or indefinitely, now takes the form of blossom, and is subservient to the production of seed. 16. The Flower of Flax consists, first, of five small green leaves, crowded into a circle : this is the CALYX, or flower-cup. When its sepa- rate leaves are referred to they are called SEPALS, a name which distin- guishes them from foliage-leaves on the one hand, and from petals on the other. Then come five delicate and colored leaves (in the Flax, blue), which form the COEOLLA, and its leaves are PETALS ; then a circle of organs, in 9 10 which all likeness to leaves is lost, consisting of slender stalks with a knob at summit, the STAMENS; and lastly, in the centre, the rounded body, which becomes a pod, surmounted by five slender or stalk-like bodies. This, all together, is the PISTIL. The lower part of it, which is to contain the seeds, is the OVARY ; the slender organs surmounting this are STYLES ; the knob borne on the apex of each style is a STIGMA. Going back to the sta- mens, these are of two parts, viz. the stalk, called FILAMENT, and the body it bears, the ANTHER. Anthers are filled with POLLEN, a powdery sub- stance 'made up of minute grains. 17 The pollen shed from the anthers when they open falls upon or is conveyed to the stigmas ; then the pollen-grains set up a kind of growth (to be discerned only by aid of a good microscope), which penetrates the style : this growth takes the form of a thread more delicate than the finest spider's web, and reaches the bodies which are to become seeds (OVULES they are called until this change occurs) ; these, touched by this influence, are in- cited to a new growth within, which becomes an embryo. So, as the ovary ripens into the seed-pod or capsule (Fig. 1, etc.) containing seeds, each seed enclosing a rudimentary new plantlet, the round of this vegetable existence is completed. Fro. 9.

SECTION 3.J SEEDLINGS. 15 SECTION HI. MORPHOLOGY OP SEEDLINGS. 18. Having obtained a general idea of the growth and parts of a pha- nerogamous plant from the common Flax of the field, the seeds and seed- lings of other familiar plants may be taken up, and their variations from the assumed pattern examined. 19. Germinating Maples are excellent to begin with, the parts being so much larger than in Flax that a common magnifying glass, although convenient, is hardly necessary. The only disadvantage is that fresh seeds are not readily to be had at all seasons. 20. The seeds of Sugar Maple ripen at the end of summer, and germi- nate in early spring. The em- bryo fills the whole seed, in which it is nicely packed ; and the nature of the parts is ob- vious even before growth begins. There is a stemlet (caulicle) and a pair of long and narrow seed- leaves (cotyledons), doubled up and coiled, green even in the seed, and in germination at once unfolding into the first pair of foliage-leaves, though of shape quite unlike those that follow. 21. Red Maple seeds are ripe and ready to germinate at the beginning of summer, and are therefore more convenient for study. The cotyledons are crumpled in the seed, and not easy to straighten out until they unfold them- selves in germination. The story of their development into the seedling is told by the accompanying Fig. 14-20 ; and that of Sugar Maple is closely similar. No plumule or bud appears in the embryo of these two Maples until the seed-leaves have nearly attained their full growth and are acting as foliage-leaves, and until a root is formed below. There is no great store of nourishment in these thin cotyledons; so further growth has to wait until the root and seed-leaves have collected and elaborated sufficient ma- terial for the formation of the second internode and its pair -of leaves, which lending their help the third pair is more promptly produced, and so on. 22. Some change in the plan comes with the Silver or Soft White Maple. (Fig. 21-25). This blossoms in earliest spring, and it drops its large and ripened keys only a few weeks later. Its cotyledons have not at all the appearance of leaves ; they are short and broad, and (as there is no room to be saved by folding) they are straight, except a small fold at the top, a vestige of the habit of Maples in general. Their unusual thickness is due FIG. 11. Embryo of Sugar Maple, cut through lengthwise and taken out of the eed. 12, 13. Whole embryo of same just beginning to grow; a, the stemlet or caulicle, which in 13 has considerably lengthened, 16 SEEDLINGS. [SECTION 3. to the large store of nutritive matter they contain, and this prevents their developing into actual leaves. Correspondingly, their caulicle does not lengthen to elevate them above the surface of the soil ; the growth below the'cotyledons is nearly all of root. It is the little plumule or bud between them which makes the upward growth, and which, being well fed by the cotyledons, rapidly develops the next pair of leaves and raises them upon a long internode, and so on. The cotyledons all the while remain below, in the husk of the fruit and seed, and perish when they have yielded up the store of food which they contained. 23. So, even in plants so much alike as Maples, there is considerable difference in the amount of food stored up in the cotyledons by which the growth is to be made ; and there are corresponding differences in the ger- Fio. 14.

SECTION 3.] SEEDLINGS. 17 mination. The larger the supply to draw upon, the stronger the growth, and the quicker the formation of root below and of stem and leaves above. This deposit of food thickens the cotyledons, and renders them less and less leaf-like in proportion to its amount. 2i. Examples of Embryos with thickened Cotyledons. In the Pumpkin and Squash (Fig. 26, 27), the cotyledons are well supplied with nourishing matter, as their sweet taste demonstrates. Still, they are flat and not very thick. In germination this store is promptly utilized in the devel- opment of the caulicle to twenty or thirty times its length in the seed, and to corresponding thickness, in the formation of a cluster of roots at its lower end, and the early pro- duction of the incipient plumule ; also in their own growth into effi- cient green leaves. The case of our common Beau (Phaseolus vul- garis, Fig. 28-30) is nearly the same, except that the cotyledons are much more gorged ; so that, although carried up into the air and light upon the lengthening caulicle, and there acquiring a green color, they never expand into useful leaves. Instead of this, they nourish into rapid growth the plumule, which is plainly visible in the seed, as a pair of incipient leaves ; and these form the first actual foliage. 25. Very similar is the germination of the Beech (Pig. 31-33), except that the caulicle lengthens less, hardly raising the cotyledons out of the ground. Nothing would be gained by elevating them, as they never grow out into efficient leaves ; but the joint of stem belonging to the plumule lengthens well, carrying up its pair of real foliage-leaves. 26. It is nearly the same in the Bean of the Old World (Vicia Faba, here called Horse Bean and Windsor Bean) : the caulicle lengthens very little, does not undertake to elevate the heavy seed, which is left below or FIG. 21.

[SECTION 3. upon the surface of the soil, the flat but thick cotyledons remaining in it, and supplying food for the growth of the root below and the plumule above. In its near relative, the Pea (Fig. 34, 35), this use of cotyledons for storage only is most completely carried out. For they are thickened to the utmost, even into hemispheres; the caulicle does not lengthen at all ; merely sends out roots from the lower end, and develops its strong plu- mule from the upper, the seed remaining unmoved underground. That is, in technical language, the germination is hypogteous. 27. There is sufficient nourishment in the cotyledons of a pea to make a very considerable growth before any actual foliage is required. So it is the stem-portion of the plumule which is at first conspicuous and strong- growing. Here, as seen in Fig. 35, its lower nodes bear each a useless leaf-scale instead of an efficient leaf, and only the later ones bear leaves fitted for foliage. Fio. 26.

This hypog&ous germination is exemplified on a larger scale by the Oak (Pig. 36, 37) and Horse-chestnut (Fig. 38, 39); but in these the downward growth is wholly a stout tap-root. It is not the caulicle; for this lengthens hardly any. Indeed, the earliest growth which carries the very short caulicle out of the shell comes from the formation of foot- stalks to the cotyledons ; above these develops the strong plumule, below grows the stout root. The growth is at first entirely, for a long time FIG. 31. A Beech-nut, cut across. 32.

[SECTION 3. mainly, at the expense of the great store of food in the cotyledons. These, after serving their purpose, decay and fall away. 29. Such thick cotyledons never separate; indeed, they sometimes grow together by some part of their contiguous faces ; so that the germination seems to proceed from a solid bulb-like mass. This is the case in a horse-chestnut. 30. Germinating Embryo supplied by its own Store of Nourishment, i. e. the store in the cotyledons. This is so in all the illustrations thus far, essentially so even in the Flax. This nourishment was supplied by the mother plant to the ovule and seed, and thence taken into the embryo during its growth. Such embryos, filling the whole seed, are comparatively large and strong, and vigorous in germination in proportion to the amount of their growth while connected with the parent plant. 31. Germinating Embryo supplied from a Deposit outside of It- self. This is as common as the other mode ; aud it occurs iu all degrees. Fio. 36.

SECTION 3.] SEEDLINGS. 21 Some seeds have very little of this deposit, but a comparatively large em- bryo, with its parts more or less developed and recognizable. In others this deposit forms the main bulk of the seed, and the embryo is small or minute, and comparatively rudimentary. The following illustrations exem- plify these various grades. When an embryo in a seed is thus surrounded by a white substance, it was natural to liken the latter to the white of an egg, and the embryo or germ to the yolk. So the matter around or by the side of the embryo was called the Albumen, i. e. the white of the seed. The analogy is not very good ; and to avoid ambiguity some botan- ists call it the ENDOSPERM. As that means iu English merely the inwards of a seed, the new name is little better than the old one ; and, since we do not change names in botany except when it cannot be avoided, this name of albu- men is generally kept up. A seed with such a deposit is albuminous, one with none is exal- buminous. 32. The ALBUMEN forms the main bulk of the seed in wheat, maize, rice, buckwheat, and the like. It is the floury part of the seed. Also of the cocoa-nut, of coffee (where it is dense and hard), etc. ; while in peas, beans, almonds, and in most edible nuts, the store of food, al- though essentially the same in nature and in use, is in the embryo itself, and therefore is not counted as anything to be separately named. In both forms this concentrated food for the germinating plant is food also for man and for animals. 33. For an albuminous seed with a well-developed embryo, the com- mon Morning Glory (Ipomcea purpurea, Fig. 40-43) is a convenient exam- ple, being easy and prompt to grow, and having all the parts well apparent. The seeds (duly soaked for examination) and the germination should be compared with those of Sugar and Red Maple (19-21). The only essen- tial difference is that here the embryo is surrounded by and crumpled up in the albumen. This substance, which is pulpy or mucilaginous in fresh and young seeds, hardens as the seed ripens, but becomes again pulpy in germination ; and, as it liquifies, the thin cotyledons absorb it by their FIG. 40.

It supplements the nutritive matter contained in the embryo. Both together form no large store, but sufficient for establishing the seedling, with tiny root, stem, and pair of leaves for initiating its independent growth; which in due time proceeds as in Tig. 44, 45. 34. Smaller embryos, less developed in the seed, are more dependenl upon the extraneous supply of food. The figures 46-53 illustrate fouf grades in this respect. The smallest, that of the Peony, is still large enough to be seen with a hand magnifying glass, and even its cotyledons may be discerned by the aid of a simple stage microscope. 35. The broad cotyledons of Mirabilis, or Four-o'clock (Fig. 52, 53), with the slender caulicle almost encircle and enclose the floury albumen, instead of being enclosed in it, as in the other illustrations. Evidently here the germinating embryo is principally fed by one of the leaf-like coty- ledons, the other being out of contact with the supply. In the embryo of Abronia (Fig. 54, 55), a near relative of Mirabilis, there is a singular modification ; one cotyledon is almost wanting, being reduced to a rudi- ment, leaving it for the other to do the work. This leads to the question of the 36. Number of Cotyledons. In all the preceding illustrations, the embryo, however different in shape and degree of development, is evidently Fio. 44.

Im other words, the embryos so far examined are all 37. Dicotyledonous, that is, two-cotyledoned. Plants which are thus similar in the plan of the embryo agree likewise in the *eneral structure of 60 62 53 their stems, leaves, and blossoms ; and thus form a class, named from their embryo DICOTYLEDONES, or in English, DICOTYLEDONOUS PLANTS. So long a name being inconvenient, it may be shortened into DICOTTLS. 38. Polycotyledonous is a name employed for the less usual case in which there are more than two cotyledons. The Pine is the most familiar case. This occurs in all Pines, the number of cotyledons varying from three to twelve ; in Fig. 56, 57 they are six. Note that they are all on the same level, that is, belong to the same node, so as to form a circle or whorl at the summit of the caulicle. When there are only three cotyledons, they divide the space equally, are one third of the circle apart. When only two they are 180 apart, that is, are opposite. 39. The case of three or more cotyledons, which is constant in Pines and in some of their relatives (but not in all of them), is occasional among Dicotyls. And the polycotyledonous is only a variation of the dicotyledonous type, a difference in the number of leaves in the whorl ; for a pair is a whorl reduced to two members. Some suppose that there are really only FIG. 46. Section of a seed of a Peony, showing a very small embryo in the albumen, near one end. 47. This embryo detached, and more magnified. FIG. 48.

But as leaves are often in whorls on ordinary stems, they may be so at the very beginning. 40. MonocotyledODOus (meaning with single cotyledon) is the i lame of the one-coty- - 'ledoned sort of embryo. This goes along " with peculiarities in sten t, leaves, and flowers ; which all together assouiate such plants into a great class, called MONOCOTYLEDONOUS PLANTS, or, for shortness, MONOCOTYLS. It means merely that the leaves are alternate from the very first. 41. In Iris (Fig. 58, 59) the embryo in the seed is a small cylinder at one end of the mass of the albumen, with no apparent dis- tinction of parts. The end which almost touches the seeii-coat is caulicle; the other end belongs to the solitary cotyledon. In germination the whole lengthen? (but mainly the cotyledon) only enough to push the proximate end fairly out of the seed : front this end the root is formed ; and from a little higher the plumule later emerges. It would appear, therefore, that the cotyledon answers to a raiaute leaf rolled up, and that a chink through ^hich the plumule grows out is a part of the in rolled edges. The embryo of Indian Corn shows these parts on a larger scale and in a more open state (Fig. 66- 68). There, in the seed, the cotyledon remains, imbibing nourishment from fhe softened albu- men, and transmitting it to the growing root below and new-forming leaves above. 49. The general plan is the st me in the Onion (Fig. 60-65), but witn a striking difference. The embryo is long, and coiled in the albumen of the .seed. To ordinary examination it shows no distinction of parts. But germination plainly shows that all except the lower end of it is cotyledon. For after it has lengthened into a long thread, the chink from which the Fio. 50. Section of a Pine-seed, showing its polycotyledonous embryo in the centre of the albumen; moderately magnified. 57.

Not only does the cotyledon lengthen enormously in the seedling, but (un- like that of Iris, Indian Corn, and all FIG. 62.

[SECTION 3. the cereal grains) it raises the comparatively light seed into the air, the tip still remaining in the seed and feeding upon the albumen. When this food is exhausted and the seedling is well es- tablished in the soil, the upper end decays and the emptied husk of the seed falss away. 43. In Maize or In- dian Corn (Tig. 66-70), the embryo is more de- veloped in the seed, and its parts can be made out. It lies against the starchy albumen, but is not enclosed therein. The larger part of it is the cotyledon, thickish, its edges involute, and its back in contact with the albumen ; partly enclosed by it is the well-devel- oped plumule or bud which is to grow. For the cotyledon remains in the seed to fulfil its office of imbibing nourishment from the softened albu- men, which it conveys to the growing sprout ; the part of this sprout which is visible is the first leaf of the plumule rolled up into a sheath and enclosing the rudiments of the succeeding leaves, at the base enclosing even the minute caulicle. In germination the first leaf of the plumule develops only as a sort of sheath, protecting the tender parts within; the second and the third form the first foliage. The caulicle never lengthens : the first root, which is formed at its lower end, or from any part of it, has to break through the enclosing sheath ; and succeeding roots soon spring from all or any of the nodes of the plumule. 44. Simple-stemmed Plants are thus built up, by the continuous pro- duction of one leaf-bearing portion of stem from the summit of the preced- ing one, beginning with the initial stem (or caulicle) in the embryo. Some Dicotyls and many Monocotyls develop only in this single line of growth (as to parts above ground) until the flowering state is approached. For some examples, see Cycas (Fig. 71, front, at the left) ; a tall Yucca or Spanish Bayonet, and two Cocoa-nut Palms behind ; at the right, a group of Sugar- canes, and a Banana behind. FIG. 71. Simple-stemmed vegetation. SECTION 4.] BUDS. 27 SECTION IV. GROWTH FROM BUDS : BRANCHING. 45. Most plants increase the amount of their vegetation by branching, that is, by producing lateral shoots. 46. Roots branch from any part and usually without definite order. Stems normally give rise to branches only at definite points, namely, at the nodes, and there only from the axils of leaves. 47. Buds (Fig. 72, 73). Every incipient shoot is a Bud (12). A stem continues its growth by its terminal bud; it branches by the forma- tion and development of lateral buds. As normal lateral buds occupy the axils of leaves, they are called axillary buds. As leaves are symmetrically arrauged on the stem, the buds in their axils and the branches into which axillary buds grow partake of this symmetry. The most conspicuous buds are the scaly winter- buds of most shrubs and trees of temperate and cold climates ; but the name belongs as well to the forming shoot or branch of any herb. 48. The Terminal Bud, in the most general sense, may be said to exist in the embryo, as cotyledons, or the cotyledons and plumule, and to crown each successive growth of the simple stem so long as the summit is capable of growth The whole ascending growth of the Palm, Cy- cas, and the like (such as in Fig. 71) is from a terminal bud. Branches, being repetitions of the main stem and growing in the same way, are also lengthened by terminal buds. Those of Horse-chestnut, Hickory, Maples, and such trees, being the resting buds of winter, are conspicu- ous by their protective covering of scales. These bud-scales, as will hereafter be shown, are themselves a kind of leaves. 49. Axillary Buds were formed on these annual shoots early in the summer. Occasion- ally they grow the same season into branches ; at least, some of them are pretty sure to do so whenever the growing terminal bud at the end of the shoot is injured or destroyed. Otherwise they may lie dormant until the following spring. In many trees or shrubs these axillary buds do not show themselves until spring ; but if searched for, they may be detected, though of small size, hidden under the bark. Sometimes, although early FIG. 72. Shoot of Horse-chestnut, of one year's growth, taken in autumn after th leaves have fallen; showing the large terminal bud and smaller axillary buds- FIG. 73. Similar shoot of Shagbark Hickory, Carya alba. 28 BUDB. [SECTION 4. formed, they are concealed all summer long under the base of the leaf-stalk, which is theu hollowed out into a sort of inverted cup, like a candle- extinguisher, to cover them ; as in the Locust, the Yellow.wood, or more strikingly in the Button-wood or Plane-tree (Fig. 74). 50. The leaf '-scars, so conspicuous in Fig. 72, 73, under each axillary bud, mark the place where the stalk of the subtending leaf was attached until it fell in autumn. 51. Scaly Buds, which are well represented fa Fig. 72, 73, commonly belong to trees and shrubs of countries in which growth is suspended dur- ing winter. The scaly coverings protect the tender young parts beneath, not so much by keeping out the cold, which of course would penetrate the bud in time, as by shielding the interior from the effects of sudden changes. There are all gradations between these and 52. Naked Buds, in which these scales are inconspicuous or wanting, as in most herbs, at least above ground, and most tropical trees and shrubs. But nearly related plants of the same climate may differ widely in this re- spect. Rhododendrons have strong and scaly winter-buds ; while in Kalmia they are naked. One species of Viburnum, the Hobble-bush, has com- pletely naked buds, what would be a pair of scales developing into the first leaves in spring ; while another (the Snowball) has conspicuous scaly buds. 53. Vigor of Vegetation from strong buds. Large and strong buds, like those of the Horse-chestnut, Hickory, and the like, contain several leaves, or pairs of leaves, ready formed, folded and packed away in small compass, just as the seed-leaves of a strong embryo are packed away in the seed : they may even contain all the blossoms of the ensuing season, plainly visible as small buds. And the stems upon which these buds rest are filled with abundant nourishment, which was deposited the summer before in the FIG. 74. An axillary bud, concealed under the hollowed base of the leafstalk, in Buttonwood or Plane-tree. SECTION 4.] BUDB. 29 wood or in the bark. Under the surface of the soil, or on it covered with the fallen leaves of autumu, similar strong buds of our perennial herbs maj be found ; while beneath are thick roots, rootstocks, or tubers, charged with a great store of nourishment for their use. This explains how it is that vegetation from such buds shoots forth so vigorously in the spring of the year, and clothes the bare and lately frozen surface of the soil, as well as the naked boughs of trees, very promptly with a covering of fresh green, and often with brilliant blossoms. Everything was prepared, and even formed, beforehand : the short joints of stem in the bud have only to lengthen, and to separate the leaves from each other so that they may un- fold and grow. Only a small part of the vegetation of the season comes directly from the seed, and none of the earliest vernal vegetation. This is all from buds which have lived through the winter. 64. The Arrangement of Branches, being that of axillary buds, answers to that of the leaves. Now leaves principally are either opposite or alternate. Leaves are opposite when there are two from the same joint of stem, as in Maples (Fig. 20), the two being on opposite sides of the stem ; and so the axillary buds and branches are opposite, as in Fig. 75. Leaves are alter- nate when there is only one from each joint of stem, as in the Oak, Lime- tree, Poplar, Button-wood (Fig. 74), Morning-Glory (Fig. 45, not counting the seed-leaves, which of course are opposite, there being a pair of them) ; also in Indian Corn (Fig. 70), and Iris (Fig. 59). Consequently the axillary buds are also alternate, as in Hickory (Fig. 73) ; and the branches they form alternate, making a different kind of spray from the other mode, one branch shooting on one side of the stem and the next on some other. For in the alternate arrangement no leaf is on the same side of the stem as the one next above or next below it. 55. But the symmetry of branches (unlike that of the leaves) is rarely complete. This is due to several causes, and most commonly to the 56. Non-development of buds. It never happens that all the buds grow. If they did, there might be as many branches in any year as there were leaves the year before. And of those which do begin to grow, a /arge portion perish, sooner or later, for want of nourishment, or for want of light, or because those which first begin to grow have an advantage, which they are apt to keep, taking to themselves the nourishment of the stem, and starving the weaker buds. In the Horse-chestnut (Fig. 72), Hickory (Fig. 73), Magnolia, and most other trees with large scaly buds, the terminal bud is the strongest, and has the advantage in growth ; and next in strength are the upper axillary buds : while the former continues the shoot of the last year, some of the latter give rise to branches, and the rest fail to grow. In the Lilac also (Fig. 75), the uppermost axillary buds are stronger than the lower ; but the terminal bud rarely appears at all; in its place the uppermost pair of axillary buds grow, and so each stem branches every year into two, mating a repeatedly two-forked ramification, as in Fig. 76. 30 BUDS. [SECTION 4. 57. Latent Buds. Axillary buds that do not grow at the proper season, and especially those which make no appearance externally, may long remain latent, and at length upon a favorable occasion start into growth, so form- ing branches apparently out of place as they are out of time. The new shoots seen springing directly out of large stems may sometimes orig- inate from such latent buds, which have preserved their life for years. But commonly these arise from 58. Adventitious Buds. These are buds which certain shrubs and trees produce anywhere on the sur- face of the wood, especially where it has been injured. They give risfr to the slender twigs which often feather the sides of great branches of our American Elms. They some- times form on the root, which natu- rally is destitute of buds ; they are even found upon some leaves ; and they are sure to appear on the trunks and roots of Willows, Pop- lars, and Chestnuts, when these are wounded or mutilated. Indeed Osier-Willows are pollarded, or out off, from time to time, by the culti- vator, for the purpose of produc- ing a crop of slender adventitious twigs, suitable for basket-work. Such branches, being altogether irregular, of course interfere with the natural symmetry of the tree. Another cause of irregularity, hi certain trees and shrubs, is the formation of what are called 59. Accessory or Supernumerary Buds. There are cases where two, three, or more buds spring from the axil of a leaf, instead of the single one which is or- dinarily found there. Sometimes they are placed one over the other, as in the Aris- tolochia or Pipe- Vine, and in the Tartarean Honeysuckle (Fig. 77) ; also in the Honey-Locust, and in the Walnut and Butternut (Fig. 78), where FIG. 75. Shoot of Lilac, with winter buds ; the two uppermost axillary ones strong; the terminal not developed. 76. Forking ramification of Lilac; reduced In size. Fio. 77. Tartarean Honeysuckle, with three accessory buds in each axil. SECTION 4] 31 the upper supernumerary bud is a good way out of the axil and above the others. Arid this is here stronger than the others, and grows into a branch which is considerably out of the axil, while the lower and smaller ones commonly do not grow at all. In other cases three buds stand side by side in the axil, as in the Hawthorn, and the Red Maple (Fig. 79.) If these were all to grow into branches, they would stifle each other. But some of them are commonly flower-buds : in the Red Maple, only the middle one is a leaf-bud, and it does not grow until after those on each side of it have expanded the blossoms they contain. 60. Sorts of Buds. It may be useful to enumerate the kinds of buds which have been described or men- tioned. They are Terminal, when they occupy the summit of (or ter- minate) a stem, Lateral, when they are borne on the side of a stem ; of which the regular kind is the Axillary, situated in the axil of a leaf. These are Accessory or Supernumerary, when they are in addition to the normal solitary bud; and these are Collateral, when side by side ; Superposed, when one above another; Extra-axillary, when they appear above the axil, as some do when superposed, and as occasionally is the case when single. Naked buds ; those which have no protecting scales. Scaly buds ; those which have protecting scales, which are altered leaves or bases of leaves. Leaf-buds, contain or give rise to leaves, and develop into a leafy shoot. Flower-buds, contain or consist of blossoms, and no leaves. Mixed buds, contain both leaves and blossoms. 61. Definite annual Growth from winter buds is marked in most of the shoots from strong buds, such as those of the Horse-chestnut and Hickory (Fig. 72, 73). Such a bud generally contains, already formed in miniature, all or a great part of the leaves and joints of stem it is to pro- duce, makes its whole growth in length in the course of a few weeks, or sometimes even in a few days, and then forms and ripens its buds for the next year's similar growth. 62. Indefinite annual Growth, on the other hand, is well marked in such trees or shrubs as the Honey-Locust, Sumac, and in sterile shoots of FIG. 78. Butternut branch, with accessory buds, the uppermost above the axil. FIG. 79. Red-Maple branch, with accessory buds placed side by side. The an- nular lines toward the base in this and in Fig. 72 are scars of the bud-scales, and indicate the clace of the winter-bud of the preceding year. 32 BUDS. [SECTION 4. the "Rose, Blackberry, and Raspberry. That is, these shoots ave apt to grow all summer long, until stopped by the frosts of autumn or some other cause. Consequently they form and ripen no terminal bud protected by scales, and the upper axillary buds are produced so late in the season that they have no time to mature, nor has their wood time to solidify and ripen. Such stems therefore commonly die back from the top in winter, or at least all their upper buds are small and feeble ; so the growth of the suc- ceeding year takes place mainly from the lower axillary buds, which are more mature. 63. Deliquescent and Excurrent Growth. In the former case, and wherever axillary buds take the lead, there is, of course, no single main stem, continued year after year in a direct line, but the trunk is soon lost in the branches. Trees so formed commonly have rounded or spreading tops. Of such trees with deliquescent stems, that is, with the trunk dissolved, as it were, into the successively divided branches, the common American Elm (Fig. 80) is a good illustration. 64. On the other hand, the main stem of Firs and Spruces, unless de- stroyed by some injury, is carried on in a direct line throughout the whole growth of the tree, by the development year after year of a terminal bud : this forms a single, uninterrupted shaft, an excurrent trunk, which can- not be confounded with the branches that proceed from it. Of such spiry or spire-shaped trees, the Firs or Spruces are characteristic and familiar examples There are all gradations between the two modes. FIQ. 80. An American Elm, with Spruce-trees, and on the left Arbor Vitae. SECTION 5.] ROOTS. 33 SECTION V. ROOTS. 65. It is a property of stems to produce roots. Stems do not spriug from roots in ordinary cases, as is generally thought, but roots from stems. When perennial herbs arise from the ground, as they do at spring-time, they rise from subterranean stems. 66. The Primary "Root, is a downward growth from the root-end of the caulicle, that is, of the initial stem of the embryo (Fig. 5-7, 81). I* it goes on to grow it makes a main or tap-root, as in Fig. 37, etc. Som plants keep this main root throughout their whole life, and send off only small side branches ; as in the Carrot aud Radish : and in various trees, like the Oak, it takes the lead of the side-branches for several years, unless accidentally injured, as a strong tap- root. But commonly the main root divides off very soon, and is lost in the branches. Multiple primary roots now and then occur, as in the seedling of Pumpkin (Fig. 27), where a cluster is formed even at the first, from the root-end of the caulicle. 67. Secondary Roots are those which arise from other parts of the stem. Any pari of the stem may produce them, but they most readily come from the nodes. As a general rule they naturally spring, or may be made to spring, from almost any young stem, when placed in favorable circumstances, that is, when placed in the soil, or otherwise supplied with moisture and screened from the light. For the special tendency of the root is to avoid the light, seek moisture, and therefore to bury itself in the soil. Propagation by division, which is so common and so very important in cultivation, depends upon the proclivity of stems to strike root. Stems or branches which remain uuder ground give out roots as freely as roots themselves give off branches. Stems which creep on the ground most commonly root at the joints ; so will most branches when bent to the ground, as in propagation by layer- ing; and propagation by cuttings equally depends upon the tendency of the cut end of a shoot to produce roots. Thus, a piece of a plant which has stem and leaves, either developed or in the bud, may be made to produce roots, and so become an independent plant. Fio. 81.

Steins are asceudiug axes; roots are descending axes. Stems grow by the successive development of internodes (13), one after another, each leaf-bearing at its summit (or node) ; so that it is of the essen- tial nature of a stem to bear leaves. Roots bear no leaves, are not distinguishable into nodes and inter-. nodes, but grow on continuously from the lower end. They commonly branch freely, but not from any fixed points nor in definite order. 69. Although roots generally do not give rise to stems, and there- fore do not propagate the plant, exceptions are not uncommon. For as stems may produce ad- ventitious buds, so also may roots. The roots of the Sweet Potato among herbs, and of the Osage Orange among trees freely produce adventi- tious buds, developing into leafy shoots; and so these plants are propagated by root-cut- tings. -But most growths of subterranean origin which pass for roots are forms of stems, the common Potato for example. 70. Roots of ordinary kinds and uses may be roughly classed mlojibrous 71. Fibrous Roots, such as those of Indian Corn (Fig. 70), of most annuals, and of many perennials, serve only for absorption : these are slender or thread-like. Fine roots of this kind, and the fine branches which most roots send out are called ROOTLETS. 72. The whole surface of a root absorbs moisture from the soil while fresh and new ; and the newer roots and rootlets are, the more freely do they im- bibe. Accordingly, as long as the plant grows above ground, and expands fresh foliage, from which moisture largely escapes into the air, so long it continues to extend and multiply its roots in the soil beneath, renewing and increasing the fresh surface for absorbing moisture, in proportion to the demand from above. And when growth ceases above ground, and the leaves die and fall, or no longer act, then the roots generally stop growing, FIG. 83-85. Forms of tap-root, SECTION 5.] ROOTS. 35 and their soft and tender tips harden. From this period, therefore, until growth begins anew the next spriiigr, is the best time for transplanting ; especially for trees and shrubs. 73. The absorbing surface of young roots is much increased by the for- mation, near their tips, of ROOT-HAIRS (Fig. 81 82), which are delicate tubular outgrowths from the surface, through the delicate walls of which moisture is promptly imbibed. 74. Fleshy Boots are those in which the root becomes a storehouse of nourishment. Typical roots of this kind are those of such biennials as the turnip and carrot ; in which the food created in the first season's vege- tation is accumulated, to be expended the next season in a vigorous growth and a rapid development of flowers, fruit, and seed. By the time the seed is matured the exhausted root dies, and with it the whole plant. 75. Fleshy roots may be single or multiple. The single root of the commoner biennials is the primary root, or tap-root, which begins to thicken in the seedling. Names are given to its shapes, such as Conical, when it thickens most at the crown, or where it joins the stem, and tapers regularly downwards to a point, as in the Parsnip and Carrot (Fig- 84); Turnip-shaped or napiform, when greatly thickened above, but abruptly becoming slender below ; as the Turnip (Fig. 83) ; and FIG. 86. Sweet-Potato plant forming thickened roots. Some in the middle are just beginning to thicken; one at the left has grown more; one at the right is still larger. FiG. 87.

Spindle-shaped, or Fusiform, when thickest in the middle and tapering to both cuds ; as the common Radish (Fig. 85). 76. These examples are of primary roots. It will be seen that turnips, carrots, and the like, are uot pure root throughout ; for the caulicle, from the lower end of which the root grew, partakes of the thickening, perhaps also some joints of stem above : so the bud-bearing and growing top is stem. 77. A fine example of secondary roots (67), some of which remain fibrous for absorption, while a few thicken and store up food for the next season's growth, is furnished by the Sweet Potato (Fig. 86). As stated above, these are used for propagation by cuttings; for any part will produce ad- ventitious buds and shoots. The Dahlia produces fascicled (i. e. clustered) fusiform roots of the same kind, at the base of the stem (Fig. 87) : but these, like most roots, do not produce adventitious buds. The buds by which Dahlias are propagated belong to the surviving base of the stem above. 78. Anomalous Roots, as they may be sailed, are those which subserve other uses than absorption, food-storing, and fixing the plant to the soil. Aerial Roots, i. e. those that strike from stems in the open air, are common in moist and warm climates, as in the Mangrove which reaches the coast of Florida, the Banyan, and, less strikingly, in some herbace- ous plants, such as Sugar Cane, and even in Indian Corn. Such roots reach the ground at length, or tend to do so. Aerial Rootlets are abun- dantly produced by many climbing plants, such as the Ivy, Poison Ivy, Trumpet Creeper, etc., springing from the side of steins, which they fasten to trunks of trees, walls, or other supports. These are used by the plant frr climbing. 79. Epiphytes, or Air- Plants (Fig. 88), are called by the former name because commonly growing Fio. 88. Epiphytes of Florida and Georgia, viz., Epidendrum conopsenm, a small Orchid, and Tillandsia usneoides, the so-called Long Moss or Black Moss, which is no moss, but a flowering plant, also T. recurvata ; on a bough of Live Oak. SECTION 5.J ROOTS. 37 upon the trunks or limbs of other plants ; by the latter because, having no connection with the soil, they must derive their sustenance from the air only. They have aerial roots, which do not reach the ground, but are used to fix the plant to the surface upon which the plant grows : they also take a part in absorbing moisture from the air. 80. Parasitic Plants, of which there are various kinds, strike their roots, or what answer to roots, into the tissue of foster plants, or form atr tachmeuts with their surface, so as to prey upon their juices. Of this sort is the Mistletoe, the seed of which germinates on the bough where it falls or is left by birds ; and the forming root penetrates the bark and en- grafts itself into the wood, to which it becomes united as firmly as a natural branch to its parent stem ; and indeed the parasite lives just as if it were a branch of the tree it grows and feeds on. A most common parasitic herb is the Dodder; which abounds in low grounds ia summer, and coils its long and slender, leafless, yellowish stems resembling tangled threads of yarn round and round the stalks of other plants ; wherever they touch piercing the bark with minute and very short rootlets in the form of suckers, which draw out the nourishing juices of the plants laid hold of. Other parasitic plants, like the Beech-drops and Pine-sap, fasten their roots under ground upon the roots of neighboring plants, and rob them of their juices. 81. Some plants are partly parasitic ; while most of their roots act in the ordinary way, others make suckers at their tips which grow fast to the roots of other plants and rob them of nourishment. Some of oar species of Gerardia do this (Fig. 89). 82. There are phanerogamous plants, like Monotropa or Indian Pipe, the roots of which feed mainly on decaying vegetable matter in the soil. These are SAPROPHYTES, and they imitate Mushrooms and other Fungi in their mode of life. 83. Duration of Roots, etc. Roots are said to be either annual, bien- nial, or perennial. As respects the first and second, these terms may be applied either to the root or to the plant. 84. Annuals, as the name denotes, live for only one year, generally for PIG. 89.

They are of course herbs ; they spring from the seed, blossom, mature their fruit and seed, and then die, root and all. An- nuals of our temperate climates with severe winters start from the seed in spring, and perish at or before autumn. Where the winter is a moist and growing season and the summer is dry, winter annuals prevail ; their seeds germinate under autumn or winter rains, grow more or less during winter, blossom, fructify, and perish in the following spring or summer. Annuals are fibrous-rooted. 85. Biennials, of which the Turnip, Beet, and Carrot are familiar ex- amples, grow the first season without blossoming, usually thicken their roots, laying up in them a stock of nourishment, are quiescent during the winter, but shoot vigorously, blossom, and seed the next spring or summer, mainly at the expense of the food stored up, and then die completely. Annuals and biennials flower only once ; hence they have been called Monocarpic (that is, once-fruiting) plants. 86. Perennials live and blossom year after year. A perennial herb, in a temperate or cooler climate, usually dies down to the ground at the end of the season's growth. But subterranean portions of stem, charged with buds, survive to renew the development. Shrubs and trees are of course perennial ; even the stems and branches above ground live on and grow year after year. 87. There are all gradations between annuals and biennials, and between these and perennials, as also between herbs and sbrubs ; and the distinc- tion between shrubs and trees is quite arbitrary. There are perennial herbs and even shrubs of warm climates which are annuals when raised in a cli- mate which has a winter, being destroyed by frost. The Castor-oil plant is an example. There are perennial herbs of which only small portions survive, as off-shoots, or, in the Potato, as tubers, etc. SECTION VI. STEMS. 88. The Stem is the axis of the plant, the part which bears all the other organs. Branches are secondary stems, that is, stems growing out of stems. The stem at the very beginning produces roots, in most plants a single root from the base of the embryo-stem, or caulicle. As this root becomes a descending axis, so the stem, which grows in the opposite direc- tion is called the ascending axis. Rising out of the soil, the stem bears leaves ; and leaf-bearing is the particular characteristic of the stem. But there are forms of stems that remain underground, or make a part of their growth there. These do not bear leaves, in the common sense ; yet they bear rudiments of leaves, or what answers to leaves, although not in the form of foliage. The so-called stemless or acaulescent plants are those which bear no obvious stem (caulis) above ground, but only flower-stalks, and the like. SECTION 6.] STEMS. 39 89.

As to direction taken in growing, stems may, instead of growing upright or erect, be Diffuse, that is, loosely spreading in all directions. Declined, when turned or bending over to one side. Decumbent, reclining on the ground, as if too weak to stand. Assurgent or Ascending, rising obliquely upwards. Procumbent or Prostrate, lying flat on the ground from the first.

Twining or Voluble, when coiling spirally around other stems or supports; like the Morning-Glory (Fig. 90) and the Hop. 91. Certain kinds of stems or branches, appropriated to spe- cial uses, have re- ceived distinct substantive names ; such as the following : 92. A Culm, or straw-stem, such as that of Grasses and Sedges. 93. A Caudex is the old name for such a peculiar trunk as a Palm-stem ; it is also used for an upright and thick rootstock. 94. A Sucker is a branch rising from stems under ground. Such are produced abundantly by the Rose, Raspberry, and other plants said to multiply " by the root." If we uncover them, we see at once the great difference between these subterranean branches and real roots. They are only creeping branches under ground. Remarking how the upright shoots from these branches become separate FIG. 90. Twining or voluble stem of Morning-Glory. 40 STEMS, [SECTION 6. plants, simply by the dying off of the connecting under-ground stems, the gardener expedites the result by cutting them through with Ms spade. That is, he propagates the plant " by division." 95. A Stolon is a branch from above ground, which reclines or becomes prostrate and strikes root (usually from the nodes) wherever it rests on the soil. Thence it may send up a vigorous shoot, which has roots of its own, and becomes an independent plant when the connecting part dies, as it does after a while. The Currant and the Gooseberry naturally multiply in this way, as well as by suckers (which are the same thing, only the connect- ing part is concealed under ground). Stolons must have suggested the operation of layering by bending down and covering with soil branches which do not naturally make stolons ; and after they have taken root, as they almost always will, the gardener cuts through the connecting stem, and so converts a rooting branch into a separate plant. 96. An Offset is a short stolon, or sucker, with a crown of leaves at the end, as in the Houseleek (Fig. 91), which propagates abundantly in this way. 97. A Runner, of which the Strawberry presents the most fa- miliar and characteristic example, is a long and slender, tendril-like stolon, or branch from next the ground, destitute of conspicuous leaves. Each runner of the Straw- berry, after having grown to its full length, strikes root from the tip, which fixes it to the ground, then forms a bud there, which develops into a tuft of leaves, and so gives rise to a new plant, which sends out new runners to act in the same way. In this manner a single Strawberry plant will spread over a large space, or produce a great number of plants, in the course of the summer, all connected at first by the slender runners ; but these die in the following winter, if not before, and leave the plants as so many separate individuals. 98. Tendrils are branches of a very slender sort, like runners, not destined like them for propagation, and therefore always destitute of buds or leaves, being intended only for climbing. Simple tendrils are such as those of Passion-flowers (Fig. 92). Compound or branching tendrils are borne by the Cucumber and Pumpkin, by the Grape- Vine, Virginia Creeper, etc. 99. A tendril commonly grows straight and outstretched until it reaches some neighboring support, such as a stem, when its apex hooks around it to secure a hold; then the whole tendril shortens itself by coiling up spirally, and so draws the shoot of the growing plant nearer to the sup- porting object. But the tendrils of the Virginia Creeper (Ampelopsis, Fig. Fio. 91. Houseleek (Sempervivum), with offsets SECTION b. | 41 93), as also the shorter ones of the Japanese species, effect the object differ- ently, namely, by expanding the tips of the tendrils into a flat disk, with an adhesive face. This is applied to the supporting object, and it adheres firmly ; then a shortening of the tendril and its branches by coiling brings up the growing shoot close to the support. This is an adapta- tion for climbing mural rocks or walls, or the trunks of trees, to which ordinary tendrils are unable to cling. The Ivy and Poison Ivy attain the same result by means of aerial rootlets (78). 100. Some tendrils are leaves or parts of leaves, as those of the Pea (Fig. 35). The na- ture of the tendril is known by its position. A tendril from the axil of a leaf, like that of Pas- sion-flowers (rig. 92) is of course a stem, i. e. a branch. So is one which terminates a stem, as in the Grape-Vine. 101. Spines or Thorns (Fig. 95, 96) are commonly stunted and hardened branches or tips of stems or branches, as are those of Hawthorn, Honey-Locust, etc. In the Pear and Sloe all gradations occur between spines and spine-like (spinescent) branches. Spinet i day be reduced and indurated leaves ; as in the Barberry, where theit nature is revealed by their situation, underneath an axillary bud. Bnt FIG. 92.

Tips of a tendril, about the natural size, showing the disks by which they hold fast to walls, etc. 42 STEMS [SECTION 6, prickles, such as those ot Blackberry and Roses, are only excrescences of the bark, aud not branches. 102. Equally strange forms of stems are characteristic of the Cactus family (Fig. 111). These may be better understood by com- parison with 103. Subterranean Stems and Branches. These are very numerous aud various ; but they are commonly overlooked, or else are confounded with roots. From their situation they are out of or- dinary sight ; but they will well repay examination. For the veg- etation that is carried on under ground is hardly less varied or important than that above ground. All their forms may be referred to four principal kinds : namely, the Rhizoma (Rhizome) or Rootstock, the Tuber, the Corn or solid bulb, and the true Bulb. 10*. The Rootstock, or Rhi- zoma, in its simplest form, is merely a creeping stem or branch growing beneath the surface of the soil, or partly covered by it. Of this kind are the so-called creeping, running, or scaly roots, such as those by which the Mint (Fig. 97), the Couch-grass, or Quick -grass, and manj other plants, spread so rapidly and widely, " by the root," as it is said. That these are really stems, and not roots, is evident from the way in which FIG. 95. A branching thorn of Honey Locust, being an indurated leafless branch developed from an accessory bud far above the axil: at the cut portion below, three other buds (a) are concealed under the petiole. FIG. 96. Spine of Cockspur Thorn, developed from an axillary bud, as the leaf- scar below witnesses : an accessory leaf-bud is seen at its base. Fid. 97.

SECTION 6.] STEMS. 43 they grow ; from their consisting of a succession of joints ; and from the leaves which they bear on each node, in the form of small scales, just like the lowest ones on the upright stem next the ground. They also pro- duce buds in the axils of these scales, showing the scales to be leaves ; whereas real roots bear neither leaves nor axillary buds. Placed as they are in the damp and dark soil, such stems naturally produce roots, just as the creeping stem does where it lies oil the surface of the ground. 105. It is easy to see why plants with these running rootstocks take such rapid and wide possession of the soil, and why they are so hard to get rid of. They are always perennials ; the subterranean shoots live over the first winter, if not longer, and are provided with vigorous buds at every joint. Some of these buds grow in spring into upright stems, bearing foliage, to elaborate nourishment, and at length produce blossoms for re. production by seed ; while many others, fed by nour- ishment supplied from above, form a new generation of subterranean shoots ; and this is repeated over and over in the course of the season or in succeeding years. Meanwhile, as the subterranean shoots in- crease in number, the older ones, connecting the suc- cessive growths, die off year by year, liberating the already rooted side-branches as so many separate plants ; and so on indefi- nitely. Cutting these running rootstocks into pieces, therefore, by the hoe or the plough, far from destroying the plant, only accelerates the propaga- tion ; it converts one many -branched plant into a great number of separate individuals. Cutting into pieces only multiplies the pest ; for each piece (Fig. 98) is already a plantlet, with its roots and with a bud in the axil of its scale-like leaf (either latent or apparent), and with prepared nourishment enough to develop this bud into a leafy stem ; and so a single plant is all the more speedily converted into a multitude. Whereas, when the subterra- nean parts are only roots, cutting away the stem completely destroys the plant, except in the rather rare cases where the root freely produces adventitious buds. 106. Rootstocks are more commonly thickened by the storing up of considerable nourishing matter in their tissue. The common species of Iris (Fig. 164) in the gardens have stout rootstocks, which are only partly covered by the soil, and which bear foliage-leaves instead of mere scales, closely covering the upper part, while the lower produces roots. As the leaves die, year by year, and decay, a scar left in the form of a ring marks the place where each leaf was attached, that is, marks so many nodes, separated by very short internodes. 107. Some rootstocks are marked with large round scars of a different PIG. 98. A piece of the running rootstock of the Peppermint, with its node 01 joint, and an axillary bud ready to spovr. STEMS. [SECTION 6. sort, like those of the Solomon's Seal (Pig. 99), which gave this name to the plant, from their looking somewhat like the impression of a seal upon wax. Here the rootstock sends up every spring an herbaceous stalk or stem, which bears the foliage aud flowers, and dies in autumn. The sealis the circular Bear left by the death and separation of the base of the stout stalk from the living rootstock. As but one of these is formed each year, they mark the limits of a year's growth. The bud at the end of the rootstock in the figure (which was taken in summer) will grow the next spring into the stalk of the season, which, dying in autumn, will leave a similar scar, while another bud will be formed farther on, crowning the ever-advancing summit or growing end of the stem. 108. As each year's growth of stem makes its own roots, it soon becomes independent of the older parts. And after a certain age, a portion annually dies off behind, about as fast as it increases at the growing end, death following life with equal and cer- tain step, with only a narrow interval. In vigorous plants of Solomon's Seal or Iris, the living rootstock is several inches or a foot in length ; while in the short rootstock of Trillium or Birthroot (Fig. 100) life is reduced to a narrower span. 109. An upright or short rootstock, like this of Trillium, is commonly called a CAUDEX (93) ; or when more shortened and thickened it would become a corm. 110. A Tuber may be understood to be a portion of a rootstock thick- ened, and with buds (eyes) on the sides. Of course, there are all grada. tions between a tuber and a rootstock. Helianthus tuberosus, the so-called Jerusalem Artichoke (Fig. 101), and the common Potato, are typical aud familiar examples of the tuber. The stalks by which the tubers are at- tached to the parent stem are at once seen to be different from the roots, both in appearance and manner of growth. The scales on the tubers are the rudiments of leaves ; the eyes are the buds in their axils. The Potato-plant PIG. 99.

Those that bear ordinary leaves expanded in the air, to digest what they gather from it and what the roots gather from the soil, and convert it into nourishment. 2. After a while a second set of branches at the summit of the plant bear flowers, which form fruit and seed out of a portion of the nour- ishment which the leaves have pre- pared. 3. But a larger part of this nourishment, while in a liquid state, is carried down the stem, into a third sort of branches under ground, and accumulated in the form of starch at their extremities, which become tu- bers, or deposito- ries of prepared solid food, just as in the Turnip, Carrot, and Dah- lia (Fig. 83-87), it is deposited in L he root. The use of the store of food is obvious enough. In the autumn the whole plant dies, except the seeds (if it formed them) and the tubers ; and the latter are left disconnected in the ground. Just as that small portion of nourishing matter which is deposited in the seed feeds the embryo when it germinates, so the much larger portion deposited in the tuber nourishes its buds, or eyes, when they likewise grow, the next spring, into new plants. And the great supply enables them to shoot with a greater vigor at the beginning, and to produce a greater amount of vegetation than the seedling plant could do in the same space of time ; which vegetation in turn may prepare and store up, in the course of a few weeks or months, the largest quantity of solid nourishing material, in a form most available for food. Taking advantage of this, man has transported the Potato from the cool Andes of Chili to other cool climates, and makes it yield him a copious supply of food, especially important in countries where the season is too short, or the summer's heat too little, for profitably cultivating the principal grain-plants. 111. The Conn or Solid Bulb, like that of Cyclamen (Fig. 103), and of Indian Turnip (Fig. 104), is a very short and thick fleshy subterranean stem, often broader than high. It sends off roots from its lower end, or rather face, leaves and stalks from its upper. The corm of Cyclamen goes on to enlarge and to produce a succession of flowers and leaves year after year.

It is partly consumed by the growth of the stem for the season, and the corm of the year is forming at base of the stem above the line of roots. 112. The corm of Crocus (Pig. 105, 106), like that of its relative Gladiolus, is also reproduced annually, the new ones forming upon the summit and sides of the old. Such a corm is like a tuber in bud- ding from the sides, i. e. from the axils of leaves ; but these leaves, instead of being small scales, are the sheathing bases of fo- liage-leaves which covered the surface. It resem- bles a true bulb in having these sheaths or broad scales ; but in the corm or solid bulb, this solid part or stem makes up the principal bulk. 113. The Bulb, strictly so-called, is a stem like a reduced corm as to its solid part (or plate) ; while the main body consists of thickened scales, which are leaves or leaf-bases. These are like bud- scales ; so that in fact a bulb is a bud with fleshy scales on an exceedingly short stem. Compare a White Lily bulb (Fig. 107) with the strong scaly buds of the Hickory and Horse-chestnut (Fig. 72 and 73), and the resemblance will appear. In corms, as in tubers and rootstocks, the store of food for future growth is deposited in the stem ; while in the bulb, the greater part is deposited in the bases of the leaves, changing them into thick scales, which closely overlap or enclose one another. 114. A Scaly Bulb (like that of the Lily, Fig. 107, 108) is one in which the scales are thick but comparatively narrow. 115. A Tunicated or Coated Bulb is one in which the scales enwrap each other, forming concentric coats or layers, as in Hyacinth and Onion. FIG. 103.

Bulblets are very small bulbs growing out of larger ones ; or small bulbs produced above ground oil some plants, as in the axils of the leaves of the bulbiferous Lilies of the gardens (Fig. 110), and often iu the flower-clusters of the Leek and Onion. They are plainly buds with thickened scales. They never grow into branches, but detach themselves when full grown, fall to the ground, and take root there to form new plants. 117. Consolidated Vegetation. An ordinary herb, shrub, or tree is evidently constructed on the plan developing an extensive surface. In fleshy rootstocks, tubers, corms, and bulbs, the more enduring portion of the plant is con- centrated, and reduced for the time of struggle (as against drought, heat, or cold) to a small amount of exposed surface, and this mostly sheltered in the soil. There are many similar consolidated forms which are not subterranean. Thus plants like the Houseleek (Fig. 91) imitate a bulb. Among Cactuses the columnar species of Cereus (Fig. Ill, 6), may be lik- ened to rootstocks. A green rind serves the purpose of foliage ; but the surface is as nothing compared with an ordinary leafy plant of the same bulk. Compare, for instance, the largest Cactus known, the Giant Cereus of the Gila River (Fig. Ill, in the background), which rises to the height of fifty or sixty feet, with a common leafy tree of the same height, such as that in Fig. 89, and estimate how vastly greater, even without the foli- age, the surface of the latter is than that of the former. Compare, in the FIG. 107. Bulb of a wild Lily. 108. The same divided lengthwise, showing two forming buds of the next generation. FIG. 109.

[SECTION 6. same view, an Opuntia or Prickly-Pear Cactus, its stem and branches formed of a succession of thick and flattened joints (Fig. Ill, a), which may be likened to tubers, or an Epiphyllum (a?), having short and flat joints, with an ordinary leafy shrub or herb of equal size. And finally, in Melon-Cactuses, Echinocactus (c), or other globose forms (which may be likened to permanent conns), with their globular or bulb-like shapes, we have plants in the compactest shape ; their spherical figure being such as to expose the least possible amount of substance to the air. These are adaptations to climates which are very dry, either throughout or for a part of the year. Similarly, bulbous and corm-beariug plants, and the like, are examples of a form of vegetation which in the growing season may expand a large surface to the air and light, while during the period of rest the living vegetable is reduced to a globe, or solid form of the least possible surface; and this protected by its outer coats of dead and dry scales, as well as by its situation under ground. Such are also adapted to a season of drought. They largely belong to countries which have a long hot season of little or no rain, when, their stalks and foliage above and their roots beneath early perishing, the plants rest securely in their compact bulbs, filled with nourishment and retaining their moisture with great tenacity, until the rainy season comes round. Then they shoot forth leaves and flowers with wonderful rapidity, and what was perhaps a desert of arid sand becomes green with foliage and gay with blossoms, almost in a day. SECTION 7.J ORDINARY LEAVES. 49 SECTION VII. LEAVES. 118. STEMS bear leaves, at definite points (nodes, 13) ; and these are produced in a great variety of forms, and subserve various uses. The commonest kind of leaf, which therefore may be taken as the type or pattern, is an expanded green body, by means of which the plant exposes to the air and light the matters which it imbibes, exhales certain portions, and assimilates the residue into vegetable matter for its nourishment and growth. 119. But the fact is already familiar (10-30) that leaves occur under other forms and serve for other uses, for the storage of food already assimilated, as in thickened seed-leaves and bulb-scales ; for covering, as in bud-scales ; and still other uses are to be pointed out. Indeed, sometimes they are of no service to the plant, being reduced to mere scales or rudi- ments, such as those on the rootstocks of Peppermint (Fig. 97) or the tubers of Jerusalem Artichoke (Fig. 101). These may be said to be of service only to the botanist, in explaining to him the plan upon which a plant is constructed. 120. Accordingly, just as a rootstock, or a tuber, or a tendril is a kind of stem, so a bud-scale, or a bulb-scale, or a cotyledon, or a petal of a flower, is a kind of leaf. Even in respect to ordinary leaves, it is natural to use the word either in a wider or in a narrower sense ; as when in one sense we say that a leaf consists of blade and petiole or leaf-stalk, and in another sense say that a leaf is petioled, or that the leaf of Hepatica is three-lobed. The connection should make it plain whether by leaf we mean leaf-blade only, or the bkde with any other parts it may have. And the student will readily understand that by leaf in its largest or morphological sense, the botanist means the organ which occupies the place of a leaf, whatever be its form or its function. 1. LEAVES AS FOLIAGE. 121. This is tautological; for foliage is simply leaves: but it is very convenient to speak of typical leaves, or those which serve the plant for assimilation, as foliage-leaves, or ordinary leaves. These may first be considered. 122. The Parts of a Leaf. The ordinary leaf, complete in its parts, consists of blade, foot-stalk, or petiole, and a pair of stipules. 123. First the BLADE or LAMINA, which is the essential part of ordinary leaves, that is, of such as serve the purpose of foliage. In structure it con- sists of a softer part, the green pulp, called parenchyma, which is traversed and supported by a fibrous frame, the parts of which are called ribs or veins, on account of a certain likeness in arrangement to the veins of animals. 50 LEAVES. [SECTION 7. The whole surface is covered by a transparent skin, the Epidermis, not unlike that which covers the surface of all fresh shoots. 124. Note that the leaf-blade expands horizontally, that is, normally presents its faces one to the sky, the other to the ground, or when the leaf is erect the upper face looks toward the stem that bears it, the lower face away from it. Whenever this is not the case there is something to be explained. 125. The framework consists of wood, a fibrous and tough material which runs from the stem through the leaf-stalk, when there is one, in the form of parallel thi-eads or bundles of fibres ; and in the blade these spread out in a hori- zontal direction, to form the ribs and veins of the leaf. The stout main branches of the framework are called the Ribs. When there is only one, as in Fig. 112, 114, or a middle one decidedly larger than the rest, it is called the Midrib. The smaller divi- sions are termed Veins; and their still smaller subdivisions, Veinlets. The latter subdivide again and again, until they be- come so fine that they are invisible to the naked eye. The fibres of which they are composed are hollow; forming tubes by which the sap is brought into the leaves and carried to every part. 126^ Venation is the name of the mode of veining, that is, of the way in which the veins are distributed in the blade. This is tf two principal kinds ; namely, the parallel-veined, and the netted-veined. 127. In Netted-veined (also called Reticulated) leaves, the veins branch off from the main rib or ribs, divide into finer and finer veinlets, and the branches unite with each other to form meshes of network. That is, they anastomose, as anatomists say of the veins and arteries of the body. The Quince-leaf, in Fig. 112, shows this kind of veining in a leaf with a single rib. The Maple, Basswood, Plane or Buttonwood (Fig. 74) show it in leaves of several ribs. 128. In parallel-veined leaves, the whole framework consists of slender ribs or veins, which run parallel with each other, or nearly so, from the base to the point of the leaf, not dividing and subdividing, nor forming meshes, except by minute cross-veinlets. The leaf of any grass, or that of the Lily of the Valley (Fig. 113) will furnish a good illustration. Such parallel veins Linnaeus called Nerves, and parallel-veined leaves are still eommonlv called nerved leaves, while those of the other kind are said to be FIG. 112. Leaf of the Quince: 6, blade; p, petiole; st, stipules. SECTION 7-3 ORDINARY LEAVES. 51 veined, terms which it is convenient to use, although these " nerves " and " veins " are all the same thing, and have no likeness to the nerves and little to tlie veius of animals. 129. Netted-veined leaves belong to plants which have a pair of seed- leaves or cotyledons, such as the Maple (Fig. 20, 24,), Beech (Fig. 33), and the fike; while pardtkl-veined or nerved leaves belong to plants with one cotyledon or true seed-leaf; such as the Iris (Fig. 59), and Indian Corn (Fig. 70). So chat a mere glance at the leaves generally tells what the structure of the bmbryo is, and refers the plant to one or the other of these two grand classes, which is a great convenience. For when plants differ from each other in some one important respect, they usually differ corres- pondingly in other respects also. 130. Parallel- veined leaves are of two sorts, one kind, and the com- monest, having the ribs or nerves all running from the base to the point of the leaf, as in the examples already given ; while in another kind they run from a midrib to the margin, as in the common Pickerel-weed of our ponds, in the Banana, in Calla (Fig. 114), and many similar plants of warm climates. 131. Netted-veined leaves are also of two sorts, as in the examples al- ready referred to. In one case the veins all rise from a single rib (the midrib), as in Fig. 112, 116-127. Such leaves are called Feather-veined or Penni -veined, i. e. Pinnately-veined ; both terms meaning the same thing, namely, that the veins are arranged on the sides of the rib like the plume of a feather on each side of the shaft. FIG. 113. A (parallel-veined) leaf of the Lily of the Valley. 114. One of the Calla Lilv- 52 LEAVES. [SECTION 7. 132. In the other case (as in Fig. 74, 129-132)) the veins branch off from three, five, seven, or nine ribs, which spread from the top of the leaf- stalk, and run through the blade like the toes of a web-footed bird. Hence these are said to be Palmately or Digitately veined, or (since the ribs di- verge like rays from a centre) Radiate-veined. 133. Since'the general outline of leaves accords with the frame-work or skeleton, it is plain that feather-veined (or penni-veined) leaves will incline to elongated shapes, or at least to be longer than broad ; while in radiate- veined leaves more rounded forms are to be expected. A glance at the following figures shows this. 134. Forms of Leaves as to General Outline. It is necessary to give names to the principal shapes, and to define them rather precisely, since they afford easy marks for distinguishing species. The same terms are used 115 116 117 1 8 119 120 for all other flattened parts as well, such as petals ; so that they make up a great part of the descriptive language of Botany. It will be a good exer- cise for young students to look up leaves answering to these names and definitions. Beginning with the narrower and proceeding to the broadest forms, a leaf is said to be Linear (Fig. 115), when narrow, several times longer than wide, and of the same breadth throughout. Lanceolate, or Lance-shaped, when conspicuously longer than wide, and tapering upwards (Fig. 116), or both upwards and downwards. Oblong (Fig. 117), when nearly twice or thrice as long as broad. Elliptical (Fig. 118) is oblong with a flowing outline, the two ends alike in width. Oval is the same as broadly elliptical, or elliptical with the breadth con- siderably more than half the length. Ovate (Fig. 119), when the outline is like a section of a hen's egg lengthwise, the broader end downward. Orbicular, or Rotund (Fig. 132), circular in outline, or nearly so. 135. A leaf which tapers toward the base instead of toward the apex may be Oblanceolate (Fig. 121) when of the lance-shaped form, only more tapering toward the base than in the opposite direction. Spatulate (Fig. 122) when more rounded above, but tapering thence to a narrow base, like an old-fashioned spatula. FIG. 115-120. A series of shapes of feather- veined leaves. SECTION 7.] ORDINARY LEAVES. 53 Obovate (Fig. 123) or inversely ovate, that is, ovate with the narrower end down. Cuneate or Cuneiform, that is, Wedge-shaped (Fig. 124), broad above and tapering by nearly straight lines to an acute angle at the base. 136. As to the Base, its shape characterizes several forms, such as Cordate or Heart-shaped (Fig. 120, 129), when a leaf of an ovate form, or something like it, has the out- /\ \ \ \^ ^|/ ^/ I /^ line of its rounded base turned in (forming a notch or sinus) where the stalk is attached. Reniform, or Kidney- shaped (Fig. 131), like the last, only rounder and broader than long. Auriculate, or Eared, having a pair - of small J2T and blunt projections, or ears, at the base, as in one species of Magnolia (Fig. 126). Sagittate, marrow -shaped, where such ears are acute and turned downwards, while the main body of the blade tapers upwards to a point, as hi the common Sagittaria or Arrow-head, and in the Arrow-leaved Polygouum (Fig. 125). Hastate, or Halberd-shaped, when such lobes at the base point outwards, giving the shape of the halberd of the olden time, as in another Polygonum (Fig. 127). Peltate, or Shield-shaped (Fig. 132), is the name applied to a curious modification of the leaf, commonly of a rounded form, where the footstalk is attached to the lower surface, instead of the base, and therefore is natu- FIG. 121, oblanceolate ; 122, spatulale ; 123, obovate ; and 124, wedge-shaped, feather-veined, leaves.

[SECTION 7. rally likened to a shield borne by the outstretched arm. The common Watershield, the Nelumbium, and the White Water-lily, and also the Man- drake, exhibit this sort of leaf. On comparing the shield-shaped leaf of the common Marsh Pennywort (Fig. 132) with that of another common species (Fig. 130), it is at once seen that a shield-shaped leaf is like a kidney-shaped (Fig. 130, 131) or other rounded leaf, with the margins at the base brought together and united. 137. As to the Apex, the following terms express the principal varia- tions : Acuminate, Pointed, or Taper-pointed, when the summit is more or less prolonged into a narrowed or tapering point; as in Fig. 133. Acute, ending in an acute angle or not prolonged point ; Fig. 134. Obtuse, with a blunt or rounded apex ; as in Fig. 135, etc. Truncate, with the end as if cut off square ; as in Fig. 136. Refuse, with rounded summit slightly indented, forming a very shallow notch, as in Fig. 137. Emarginate, or Notched, indented at the end more decidedly; as in Fig. 138. Obcordate, that is, inversely heart-shaped, where an obovate leaf is more deeply notched at the end (Fig. 139), as in White Clover and Wood-sorrel ; so as to resemble a cordate leaf inverted. Cuspidate, tipped with a sharp and rigid point ; as in Fig. 140. Mucronate, abruptly tipped with a small and short point, like a mere projection of the midrib ; as in Fig. 141. Aristate, Awn-pointed, and Bristle-pointed, are terms used when this mucronate point is extended into a longer bristle-form or slender appen- dage. . The first six of these terms can be applied to the lower as well as to the upper end of a leaf or other organ. The others belong to the apex only. 138. As to degree and nature of Division, there is first of all the dif- ference between Simple Leaves, those in which the blade is of one piece, however much it may be cut up, and Compound Leave*, those in which the blade consists of two or more sep- arate pieces, upon a common leaf-stalk or support. Yet between these two kinds every intermediate gradation is to be met with. 139. As to Particular Outlines of Simple Leaves (and the same applies to their separate parts), they are FIG. 133-141. Forms of the apex of leaves. SECTION 7.J ORDINARY LEAVES. 55 "Entire, when their general outline is completely filled out, so that the margin is an even line, without teeth or notches. Serrate, or Saw-toothed, when the margin only is cut into sharp teeth, like those of a saw, and pointing forwards : as in Fig. 142. Dentate, or Toothed, when such teeth point outwards, instead of forwards ; as in Fig. 143.

Incised, Cut, or Jagged, when the margin is cut into sharp, deep, and irregular teeth or incisions ; as in Fig. 147- Lobed, when deeply cut. Then the pieces are in a general way called LOBES. The number of the lobes is briefly expressed by the phrase ttoo- lobed, three-lobed,five-lobed, many-lobed, etc., as the case may be. 140. When the depth and character of the lobing needs to be more par- ticularly specified, the following terms are employed, viz. : lobed, in a special sense, when the incisions do not extend deeper than about half-way between the margin and the centre of the blade, if so far, nnd are more or less rounded ; as in the leaves of the Post-Oak, Fig. 148, and the Hepatica, Fig. 152. Cleft, when the incisions extend half way down or more, and especially when they are sharp ; as in Fig. 149, 153. And the phrases two-cleft, or, in the Latin form, bifid, three-cleft or trifid, four-cleft or quadrifid, Jive- cleft or quinquefid, etc., or many -cleft, in the Latin form, multifid, express the number of the Segments, or portions. Parted, when the incisions are still deeper, but yet do not quite reach to the midrib or the base of the blade; as in Fig. 150, 154. And the terms two-parted, three-parted, etc., express the number of such divisions. Divided, when the incisions extend quite to the midrib, as in the lower part of Fig. 151, or to the leaf-stalk, as in Fig. 155 ; which really makes the Fio. 142-147. Kinds of margin of leaves. LEAVES. [SECTION 7 leaf compotmd. Here, using the Latin form, the leaf is said to be bisected, trisected (Tig. 155), etc., according to the number of the divisions. 141. The Mode of Lobing or Division corresponds to that of the veining, \i\\ei\\erpinnately veined or palmately veined. In tne former the notches or incisions, or sinuses, coming between the principal veins or ribs are directed toward the midrib : in the latter they are directed toward the apex of the petiole ; as the figures show. 142. So degree and mode of division may be tersely expressed in brief phrases. Thus, in the four upper figures of pinnately veined leaves, the first is said to be pinnately lobed (in the special sense), the second pinnately cleft (or pinnatifid in Latin form), the third pinnately parted, the fourth pinnately divided, or pinnatisected. 143. Correspondingly in the lower row, of palmately veined leaves, the first is palmately lobed, the second palmately cleft, the third palmately parted, the fourth palmately divided. Or, in other language of the same meaning (but now less commonly employed), they are said to be digitately lobed, cleft, parted, or divided. 144. The number of the divisions or lobes may come into the phrase. Thus in the four last named 6gures the leaves are respectively palmately 119 tkree-lobed, three-cleft (or trtfid), three-parted, three-divided, or better (in Latin form), trisected. And so for higher numbers, ssjive-lobed, five-cleft, PIG. 148, pinnately lobed; 149, pinnately cleft; 150, pinnately parted; 151, pinnately divided, leaves.

SECTION 7.] ORDINARY LEAVES. 57 etc., up to many-lobed, many-cleft or multifid, etc. The same mode of ex- pression may be used for pinnately lobed leaves, as pinnately 1 -lobed, -cleft, -parted, etc. 145. The divisions, lobes, etc., may themselves be entire (without teeth or notches), or serrate, or otherwise toothed or incised; or lobed, cleft, parted, etc. : in the latter cases making twice pinnatifid, twice palmately or pinnately lobed, parted, or divided leaves, etc. From these illustrations one will perceive how the botanist, in two or three words, may describe any one of the almost eudlessly diversified shapes of leaves, so as to give a clear and definite idea of it. 146. Compound Leaves. A compound Jeaf is one which has its blade in entirely separate parts, each usually with a stalklet of its own ; and the stalklet is often jointed (or articulated) with the main leaf-stalk, just a& this 157 158 is Jointed with the stem. When this is the case, there is no doubt that the leaf is compound. But when the pieces have no stalklets, and are not jointed with the main leaf-stalk, it may be considered either as a divided simple leaf, or a compound leaf, according to the circumstances. This is a matter of names where all intermediate forms may be expected. 147. While the pieces or projecting parts of a simple leaf-blade are called Lodes, or in deeply cut leaves, etc., Segments, or Divisions, the sep- arate pieces or blades of a compound leaf are called LEAFLBTS. 148. Compound leaves are of two principal kinds, namely, the Pinnate and the Palmate; answering to the two modes of veining in reticulated ./eaves, and to the two sorts of lobed or divided leaves (141). 149. Pinnate leaves are those in which the leaflets are arranged on the sides of a main leaf-stalk; as in Fig. 156-158. They answer to the Fio. 156-158. Pinnate leaves, the first with an odd leaflet (odd-pinnate); the second with a tendril in place ef uppermost leaflets ; the third abruptly pinnate, or of even pairs. 58 LEAVES. [SECTION 7. feather-veined (i. e. pinnately-veined) simple leaf; as will be seen at once on comparing the forms. The leaflets of the former answer to the lobes or divisions of the ktter ; and the continuation of the petiole, along which the leaflets are arranged, answers to the midrib of the simple leaf. 150. Three sorts of pinnate leaves are here given. Fig. 156 is pinnate Kith an odd or end leaflet, as in the Common Locust and the Ash. Fig. 157 is pinnate with a tendril at the end, in place of the odd leaflet, as in the Vetches and the Pea. Fig. 158 is evenly or abruptly pinnate, as in the Honey-Locust. 151. Palmate (also named Digitate) leaves are those in which the leaf- lets are all borne on the tip of the leaf, stalk, as in the Lupine, the Common Clover, the Virginia Creeper (Fig. 93), and the Horse-chestnut and Buckeye (Fig. 159). They evidently answer to the radiate-veined or palmately-veined simple leaf. That is, the Clover-leaf of three leaflets is the same as a palmately three-ribbed leaf cut into three separate leaflets. And such a simple five-lobed leaf as that of the Sugar-Maple, if more cut, so as to separate the parts, would produce a palmate leaf of five leaflets, like that of the Hovse-chestnut or Buckeye. 152. Either sort of compound leaf may have any number of leaflets ; yet palmate leaves cannot well have a great many, since they are all crowded together on the end of the main leaf-stalk. Some Lupines have nine or eleven ; the Horse-chestnut has seven, the Sweet Buckeye more commonly five, the Clover three. A pinnate leaf often has only seven or five leaflets, or only three, as in Beans of the genus Phaseolus, etc. ; in some rarer cases only t3K>; in the Orange and Lemon and also in the common Barberry there is only one! The joint at the place where the leaflet is united with the petiole distinguishes this last case from a simple leaf. In other specie* of these genera the lateral leaflets also are present. 153. The leaflets of a compound leaf may be either entire (as in Fig. 126-128), or serrate, or lobed, cleft, parted, etc.; in fact, may present all the variations of simple leaves, and the same terms equally apply to them. 154. When the division is carried so far as to separate what would be one leaflet into two, three, or several, the leaf becomes doubly or twice compound, either pinnately or palmately, as the case may be. For example, while the clustered leaves of the Honey-Locust are simply pinnate, that is, once pinnate, those on new shoots are bipinnate, or twice pinnate, as in Fig. 160. When these leaflets are again divided in the same way, the leaf PlO. 169. Palmate (or digitate) leaf of five leaflets of the Sweet Buckeye, SECTION 7.] ORDINARY LEAVES. becomes thrice pinnate, or tripinnate, as in many Acacias. The first divi- sions are called Pinna ; the others, Pinnules ; and the last, or little blades themselves, Leaflets. 155. So the palmate leaf, if again compounded in the same way, be- comes twice palmate, 01, when the d ; visious are in threes, twice ternate (in Latin form biter- nate) ; if a third time compounded, thrice ternate or triternate. But if the division goes still further, or if the degree is variable, we simply say that the leaf is decom- pound ; either palmately or piu- nately decompound, as the case may be. Thus, Fig. 161 repre- sents a four times ternately com- pound (in other words a ternately decompound) leaf of a common Meadow Rue. 156. When the botanist, in de- scribing leaves, wishes to express the number of the leaflets, he may use terms like these : U/iifoliolate, for a compound leaf of a single leaflet ; from the Latiu mum, one, and foliolum, leaflet. Bifoliolate, of two leaflets, from the Latin bis, twice, an&foliolum, leaflet. Trifoliolate (or ternate), of three leaf- lets, as the Clover ; and so on. Palmately bifoliolate, trifoliolate, quadr ifoliate, plurifoliola te (of several leaflets), etc. : or else Pinnately bi-, tri-, quadri-, or pluri- foliolate (that is, of two, three, four, five, or several leaflets), as the case may be: these are terse ways of de- noting in single phrases both the num- ber of leaflets and the kind of com- pounding. 157- Of foliage-leaves having certain peculiarities in structure, the following may be noted: PIG. 160. A twice-pinnate (abruptly) leaf 01 the Honey-Locust. FIG. 161. Ternately decompound leaf of Mwadow Rue. 60 LEAVES. ^SECTION 7. 158. Perforate Leaves, In these the stem that bears them seems to run through the blade of the leaf, more or less above its base. A common Bellwort (Uvularia perfoliata, Pig. 162) is a familiar illustration. The lower and earlier leaves show it distinctly. Later, the plant is apt to produce some leaves merely clasping the stem by the sessile and heart-shaped base, and the latest may be merely sessile. So the series explains the peculiarity : in the formation of the leaf the bases, meeting around the stem, grow together there. 159. Oonnate-perfoliate. Such are the upper leaves of true Honey, suckles. Here (Tig. 163) of the opposite and sessile leaves, some pairs, especially the uppermost, in the course of their formation unite around the stem, which thus seems to run through the disk formed by their union. 160. Equitant Leaves. While ordinary leaves spread horizontally, and present one face to the sky and the other to the earth, there are some that present their tip to the sky, and their faces right and left to the horizon. Among these are the equitant leaves of the Iris or Flower-de-Luce. In- spection shows that each leaf was formed as if folded together lenythwise, FIG. 162.

It was from their straddling over each other, like a man on horseback (as is seen in the cross-section, Fig. 165), that Linnaeus, with his lively fancy, called these Equitant leaves. 161. Leaves with no distinction of Petiole and Blade. The leaves, of Iris just mentioned show one form of this. The flat but narrow leaves, of Jonquils, Daffodils, and the cylindrical leaf of Onions are other instances. Needle-shaped leaves, like those of the Pine, Larch, and Spruce, and the awl-shaped as well as the scale-shaped leaves of Junipers, Red Cedar, and Arbor- Vitse (Fig. 166), are examples. 162. Phyllodia. Sometimes an expanded petiole takes the place of the blade; as in numerous New Holland Acacias, some of which are now common in greenhouses. Such counterfeit blades are called phyllodia, meaning leaf-like bodies. They may be known from true blades by their standing edgewise, their margins being directed upwards and downwards ; while in true blades the faces look upwards and downwards; excepting in equitant leaves, as already explained. 163. Falsely Vertical Leaves. These are apparent exceptions to the rule, the blade standing edgewise in- stead of flatwise to the stem ; but this position comes by a twist of the stalk or the base of the blade. Such leaves present the two faces about equally to the light. The Compass-plant (Silphium laciniatum) is an example. So also the leaves of Bolto- nia, of Wild Lettuce, and of a vast num- ber of Australian Myrtaceous shrubs and trees, which much resemble the phyllodia of the Acacias of the same country. They are familiar in Calliste- mon, the Bottle-brush Mower, and in Eucalyptus. But in the latter the leaves of the young tree have the nor- mal structure and position. 164. Cladophylla, meaning branch- leaves. The foliage of Ruscus (the Butcher's Broom of Europe) and of Myrsiphyllum of South Africa (cultivated for decoration under the false 1G7 FIG. 166.

[SECTION 7. name of Smilax) is peculiar and puzzling. Tf these blades (Fig. 167, 168) are really leaves, they are most anomalous in occupying the axil of another leaf, reduced to a little scale. Yet they have an upper and lower face, as leaves should, although they soon twist, so as to stand more or less edge- wise. If they are branches which have assumed exactly the form and office of leaves, they are equally extraordinary in not making any further development. But in Ruscus, flowers are borne OH one face, in the axil of a little scale : and this would seem to settle that they are branches. In Asparagus just the same things as to position are thread-shaped and branch-like. 2. LEAVES OP SPECIAL CONFORMATION AND USR 165. Leaves for Storage. A leaf may at the same time serve both ordinary and special uses. Thus in those leaves of Lilies, .such as the common White Lily, which spring from the bulb, the upper and green part x serves for foliage and elaborates nourishment, while the thickened por- tion or bud-scale beneath serves for the storage of this nourishment. The thread-shaped leaf of the Onion ful- fils the same office, and the nourishing matter it prepares is deposited in its sheathing base, forming one of the concentric layers of the onion. When these layers, so thick and succulent, have given up their store to the grow- ing parts within, they are left as thin and dry husks. In a Houseleek, an Aloe or an Agave, the green color of the surface of the fleshy leaf indi- cates that it is doing the work of foliage ; the deeper-seated white por- tion within is the storehouse of the nourishment which the green surface has elaborated. So, also, the seed-leaves or cotyledons are commonly used for storage. Some, as in one of the Maples, the Pea, Horse-chestnut, Oak, etc., are for nothing else. Others, as in Beecli and in our common FIG. 169. A young Agave Americana, or Century-plant : fleshy -leaved. SECTION 7.] SPECIAL LEAVES. 63 Beans, give faiat indications of service as foliage also, chiefly in Tain. Still others, as in the Pumpkin and Flax, having served for storage, develop into the first efficient foliage. Compare 11, 22-30, and the accompanying figures. 166. Leaves as Bud-Scales serve to protect the forming parts within. Hav- ing fulfilled this purpose they commonly fall off when the shoot develops and foliage-leaves appear. Occasionally, as in Fig. 170, there is a transition of bud- scales to leaves, which reveals the nature of the former. The Lilac also shows a gradation from bud-scale to simple leaf. In Cornus florida (the Flowering Dog- wood), the four bud-scales which through the winter protect the head of forming flowers remain until blossoming, and then the base of each grows out into FIG. 170. Series of bud-scales and foliage-leaves from a developing bud of the Low Sweet Buckeye (^Esculus parviflora), showing nearly complete gradation, from A scale to a compound leaf of five leaflets; and that the scales answer to reduced petioles.

[SECTION 7. a large and very showy petal-like teaf ; the original dry scale is apparent in the notch at the apex. 167. Leaves as Spines occur in several plants. A familiar instance is that of the common Barberry (Fig. 171)- In almost any summer shoot, most of the gradations may be seen between the ordinary leaves, with sharp bristly teeth, and leaves which are reduced to a branching spine or thorn. The fact that the spines of the Barberry produce a leaf-bud in their axil also proves them to be leaves. 168. Leaves for Climbing are various in adaptation. True foliage- leaves serve this purpose ; as in Gloriosa, where the attenuated tip of a sim pie leaf (otherwise like that of a Lily) hooks around a supporting object ; or in Solanum jasminoides of the gardens (Fig. 172), and in Mauraudia, etc., where the leaf-stalk coils round and clings to a support; or in the compound leaves of Clematis and of Adlumia, in which both the leaflets and their stalks hook or coil around the support. 169. Or in a compound leaf, as in the Pea and most Vetches, and in Cobsea, while the lower leaflets serve for foliage, some of the uppermost are developed as tendrils for climbing (Fig. 167). In the common Pea this is so with all but one or two pairs of leaflets. 170. In one European Vetch, the leaflets are wanting and the whole petiole is a tendril, while the stipules become the only foliage (Fig. 173). 171. Leaves as Pitchers, or hollow tubes, are familiar in the common Pitcher-plant or Side-saddle Flower (Sarracenia, Fig. 174) of our bogs. These pitchers are generally half full of water, in which flies and other in- sects are drowned, often in such numbers as to make a rich manure for the plant. More curious are some of the southern species of Sarracenia, which seem to be specially adapted to the capture and destruction of flies and other insects. FIG. 172.

Insects are caught in another way, and more expertly, by the most extraordinary of all the plants of this country, the Dionaea or Venus's Fly- trap, which grows in the sandy bogs around Wilmington, North Carolina, Here (Fig. 176) each leaf bears at its summit an appen- dage which opens and shuts, in shape some- thing like a steel-trap, and operating much like one. For when open, no sooner does a fly alight on its surface, and brush against any one of the two or three bristles that grow there, than the trap suddenly closes, captur- ing the intruder. If the fly escapes, the trap soon slowly opens, and is ready for another capture. When retained, the insect is after a time moistened by a secretion from mi- nute glands of the inner surface, and is In the various species of Drosera or Sundew, insects are caught FIG. 174.

STIPULES. 174. A leaf complete in its parts consists of blade, leaf-stalk or petiole, and a pair of stipules. But most leaves have either fugacious or minute stipules or none at all ; many have no petiole (the blade being sessile or stalkless) ; some have no clear distinction of blade and petiole ; and many of these, such as those of the Onion and all phyllodia (] 66), consist Oi petiole only. 175. The base of the petiole is apt to be broadened and flattened, sometimes into thin margins, sometimes into a sheath which embraces the stem at the point of attachment 180 176. Stipules are such appendages, either wholly or partly separated from the petiole. When quite separate they are said to be free, as in Fig. 112.

When the two stipules unite and sheathe the stem above the insertion, as in Polygonum (Fig. 178), this sheath is called an Ocrea, from its likeness to a greave or leggin. 177. In Grasses, when the sheathing base of the leaf may answer to petiole, the summit of the sheath commonly projects as a thin and short membrane, like an ocrea : this is called a LIGULA or LIGTJLE. 178. When stipules are green and leaf-like they act as so much foliage, la the Pea they make up no small part of the actual foliage. In a related plant (Lathyrus Aphaca, Fig. 173), they make the whole of it, the remainder of the leaf being tendril. 179. In many trees the stipules are the bud-scales, as in the Beech, and very conspicuously in the Fig-tree, Tulip-tree, and Magnolia (Fig. 179). These fall off as the leaves unfold. 180. The stipules are spines or prickles in Locust and several other Leguminous trees and shrubs ; they are tendrils in Srnilax or Greenbrier f 4. THE ARRANGEMENT OP LEAVES. 181. Phyllotaxy, meaning leaf-arrangement, is the study of the position t/ leaves, or parts answering to leaves, upon the stem. 182. The technical name for the attachment of leaves to the stem is the insertion. Leaves (as already noticed, 54) are inserted in three modes. They are Alternate (Fig. 181), that is, one after another, or in other words, with only a single leaf to each node ; PIG. 181. Alternate leaves, in Linden, Lime-tree, or Basswood. FIG. 182. Opposite leaves, in Red Maple. 68 LEAVES. [SECTION 7. Opposite (Fig. 182), when there is a pair to each node, the two leaves in this case being always on opposite sides of the stem ; Wkorled or Verticillate (fig. 183) when there are more than two leaves on a node, in whica. case they divide the circle equally between them, forming a Verticel or whorl. When there are three leaves in the whorl, the leaves are one third of the circumference apart ; when four, one quarter, and so on. So the plan of opposite leaves, which is very common, is merely that of whorled leaves, with the fewest leaves to the whorl, namely, two. 183. In both modes and in all their modifica- tions, the arrangement is such as to distribute the leaves systematically and in a way to give them a good exposure to the light. 184. No two or more leaves ever grow from the same point. The so- called Fascicled or Clustered leaves are the leaves of a branch the nodes of which are very close, just as they are in the bud, so keeping the leaves in a cluster. This is evident hi the Larch (Fig. 184), in which examination shows each cluster to be made up of nume- rous leaves crowded on a spur or short axis. In spring there are only such clusters ; but in summer some of them lengthen into ordinary shoots with scat- tered alternate leaves. So, likewise, each cluster of two or three needle- shaped leaves in Pitch Pines (as in Pig. 185), or of five leaves in White Pine, answers to a similar extremely short branch, springing from the axil of a thin and slender scale, which represents a leaf of the main shoot. Por Pines produce two kinds of leaves, 1. primary, the proper leaves of the shoots, not as foliage, but in the shape of delicate scales in spring, which soon fall away ; and 2. secondary, the fascicled leaves, from buds in the axils of the former, and these form the actual foliage. Fig. 183. Whorled leaves of Galium. Fid. 184. A piece of stem of Larch with two clusters (fascicles) of numerous leaves. Fid. 185. Piece of a branch of Pitch Pine, with three leaves in a fascicle or bun- dle, in the axil of a thin scale which answers to a primary leaf. The bundle is sur- rounded at the base by a short sheath, formed of the delicate scales of the axillary bud. SECTION 7.] THEIR ARRANGEMENT, 185. Phyllotaxy of Alternate Leaves. Alternate leaves are distrib- uted along the stem in an order which is uniform for each species. The arrangement in all its modifications is said to be spiral, because, if we draw a line from the insertion (i. e. the point of attachment) of one leaf to that of the next, and so on, this line will wind spirally around the stem as it rises, and in the same species will always bear the same number of leaves for each turn round the stem. That is, any two successive leaves will always be separated from each other by an equal portion of the circum- ference of the stem. The distance in height between any two leaves may vary greatly, even on the same shoot, for that depends upon the length of the internodes, or spaces between the leaves ; but the distance as measured around the circumference (in other words, the Angular Divergence, or angle formed by any two successive leaves) is uniformly the same. 186. Two-ranked. The greatest possible di- vergence is, of course, where the second leaf stands on exactly the opposite side of the stem from the first, the third on the side opppsite the second, and therefore over the first, and the fourth over the second, This brings all the leaves into two ranks, one on one side of the stem and one on the other, and is therefore called the Two-ranked arrangement. It occurs in all Grasses, in Indian Corn, for in- stance; also, in the Basswood (Fig. 181). This is the simplest of all arrangements, and the one which most widely distributes successive leaves, but which therefore gives the fewest vertical ranks. Next is the 187. Three-ranked arrangement, that of all Sedges, and of White Hellebore. Here the second leaf is placed one third of the way round the stem, the third leaf two thirds of the way round, the fourth leaf accordingly directly over the first, the fifth over the second, and so on. That is, three leaves occur in each turn round the stem, and they are separated from each other by one third of the circumference. (Fig. 186, 187.) 188. Five-ranked is the next in the series, and the most common. It is seen in the Apple (Fig. 188), Cherry, Poplar, and the greater number of trees and shrubs. In this case the line traced from leaf to leaf will pass twice round the stem before it reaches a leaf FIG. 186.

Here the sixth leaf is over the first ; the leaves stand in five perpendicular ranks, with equal angular distance from each other; and this distance between any two successive leaves is just two fifths of the circumference of the stem. 189. The five-ranked arrangement is expressed by the fraction |. This fraction denotes the divergence of jgg the successive leaves, i. e. the air gle they form with each other : the ' numerator also expresses the num- ber of turns made round the stem by the spiral line in completing one cycle or set of leaves, namely, two ; and the denominator gives the number of leaves in each cy- cle, or the number of perpendic- ular ranks, namely, five. In the same way the fraction ^ stands for the two-ranked mode, and J for the three-ranked : and so these different sorts are expressed by yie series of fractions , , f . Other cases follow in the same numerical progression, the next being the 190. Eight-ranked arrangement. In this the ninth leaf stands over the first, and three turns are made around the stem to reach it; so it is expressed by the fraction f . This is seen in the Holly, and in the common Plantain. Then conies the 191. Thirteen-ranked arrangement, in which the fourteenth leaf is over the first, after five turns around the stem, common Houseleek (Fig. 191) is a good example. 192. The series so far, then, is \, , \, f , ^ ; the numerator and the denominator of each fraction being those of the two next preceding ones added together. At this rate the next higher should be ^ T , then Jf , and so on ; and in fact just such cases are met with, and (commonly) no others. These higher sorts are found in the Pine Family, both in the leaves and the cones and in many other plants with small and crowded leaves.

The SECTION 7.] THEIR ARRANGEMENT. 71 be made out by direct inspection. They may be indirectly ascertained, how- ever, by studying the secondary spirals, as they are called, which usually become conspicuous, at least two series of them, one turning to the right and one to the left, as shown in Fig. 191. Tor au account of the way in which the character of the phyllotaxy may be deduced from the secondary spirals, see Structural Botany, Chapter IV. 193. Phyllotaxy of Opposite and whorled Leaves. This is simple and comparatively uniform. The leaves of each pair or whorl are placed over the intervals between those of the preceding, and therefore under the intervals of the pair or whorl next above. The whorls or pairs alternate or cross each other, usually at right angles, that is, they decussate. Opposite leaves, that is, whorls of two leaves only, are far com- moner than whorls of three or four or more members. This arrangement in successive decussating pairs gives an advantageous distribution on the stem in four verti- cal ranks. Whorls of three give six vertical ranks, and so on. Note that in descriptive botany leaves in whorls of two are simply called opposite leaves ; and that the term verticillate or whorled, is employed only for cases of more than two, unless the latter number is specified. 194. Vernation or Praefoliation, the disposition of the leaf-blades in the bud, comprises two things ; 1st, the way in which each separate leaf is folded, coiled, or packed up in the bud; and 2d, the arrangement of the leaves in the bud with respect to one another. The latter of course depends very much upon the phyllotaxy, i. e. thb position and order of the leaves upon the stem. The same terms are used for it as for the arrangement of the leaves of the flower in the flower-bud. See, therefore, " ^Estivation, or Praefloration." 195. As to each leaf separately, it is sometimes straight and open in vernation, but more commonly it is either bent, folded, or rolled up. When the upper part is bent down upon the lower, as the young blade in the Tulip-tree is bent upon the leafstalk, it is said to be Inflexed or Reclined in vernation. When folded by the midrib so that the two halves are placed face to face, it is Conduplicate (Fig. 193), as in the Magnolia, the Cherry, and the Oak. W T hen folded back and forth like the plaits of a fan, it is FIG. 191.

If rolled, it may be so either from the tip downwards, as in Ferns and the Sundew (Fig. 197), when in unroll- ing it resembles the head of a crosier, and is said to be Circinate; or it may be rolled up parallel with the axis, either from one edge into a coil, when it is Con- volute (Fig. 195), as in the Apricot and Plum ; or rolled from both edges towards the midrib, sometimes inwards, when it is Invo- 196 197 198 'lute (Fig. 198), as in 'the Violet and Water - Lily ; sometimes outwards, when it is Eevolute (Fig. 196), in the Rosemary and Azalea. The figures are diagrams, representing sections through the leaf, in the way they were represented by Linuseus. SECTION VIII. FLOWEB& 196. Flowers are for the production of seed (16). Stems and branches, which for a time put forth leaves for vegetation, may at length put forth flowers for reproduction. 1 1. POSITION AND ARRANGEMENT OP FLOWERS, OR INFLOR- ESCENCE. 197. Flower-buds appear just where, leaf -buds appear; that is, they are either terminal or axillary (47-49). Morphologically, flowers answer to shoots or branches, and their parts to leaves. 198. In the same species the flowers are usually from axillary buds only, or from terminal buds only; but in some they are both axillary and terminal. 199. Inflorescence, which is the name nsed by Linnaeus to signify mode of flower-arrangement, is accordingly of three classes : namely, Indeterminate, when the flowers are in the axils of leaves, that is, are from axillary buds; Determinate, when they are from terminal buds, and so terminate a stem or branch ; and Mixed, when these two are combined. 200. Indeterminate Inflorescence (likewise, and for the same reason, called indefinite inflorescence) is so named because, as the flowers all come from axillary buds, the terminal bud may keep on growing and prolong the stem indefinitely. This is so in Moneywort (Fig. 199). SECTION 8.J INFLORESCENCE, 73 201. "VYhen Sowers thus arise singly from the axils of ordinary leaves, they are axillary and solitary, not collected into flower-clusters. 202. But when several or many flowers are produced near each other, the accompanying leaves are apt to be of smaller size, or of different shape or character : then they are called BRACTS, aud the flowers thus brought together form a cluster. The kinds of flower-clusters of the indeterminate class have re- ceived distinct names, according to their form and disposition. They are principally Raceme, Corymb, Umbel, Spike, Head, Spadix, Catkin, and Panicle. 203. In defining these it will be necessary to use some of the following terms of descriptive botany which relate to inflorescence. If a flower is stalkless, i. e. sits directly in the axil or other support, it is said to be sessile. If raised on a naked stalk of its own (as in Fig. 199) it is pedun- culate, and the stalk is a PEDUNCLE. 204. A peduncle on which a flower-cluster is raised is a Common peduncle. That which supports each separate flower of the cluster is a Partial peduncle, and is generally called a PEDICEL. The portion of the general stalk along which flowers are disposed is called the Axis of inflorescence, or, when covered with sessile flowers, the Rhachis (back-bone), and sometimes the Receptacle. The leaves of a flower-cluster generally are termed BRACTS. But when bracts of different orders are to be distinguished, those on the common pedun- cle or axis, and which have a flower in their axil, keep the name of bracts ; and those on the pedicels or partial flower- stalks, if any, that of BRACTLETS or Bracteoles. The for- mer is the preferable English name. 205. A Raceme (Fig. 200) is that form of flower-cluster in which the flowers, each on their own foot-stalk or pedicel, are arranged along the sides of a common stalk or axis of inflorescence; as in the Lily of the Valley, Currant, Bar- berry, one section of Cherry, etc. Each flower comes from the axil of a small leaf, or bract, which, however, is often 200 so small that it might escape notice, and even sometimes (as m the Mustard Family) disappears altogether. The lowest blossoms of a FIG. 199.

[SECTION 8. raceme are of course the oldest, and therefore open first, aiid the order of blossoming *s ascending from the bottom to the top. The summit, never being stopped by a terminal flower, may go on to grow, and often does so (as in the common Shepherd's Purse), producing lateral flowers one after another for many weeks. 206. A Corymb (Fig. 202) is the same as a raceme, except that it is flat and broad, either convex, or level-topped. That is, a raceme becomes a corymb by lengthening the lower pedicels while the uppermost remain 203 shorter. The axis of a corymb is short in proportion to the lower pedicels By extreme shortening of the axis the corymb may be converted into *207. An Umbel (Pig. 203) as in the Milkweed, a sort of flower-cluster where the pedicels all spring apparently from the same point, from the top of the peduncle, so as to resemble, when spreading, the rays of an umbrella ; whence the name. Here the pedicels are sometimes called the Rays of the umbel. And the bracts, when brought in this way into a cluster or circle, form what is called an INVOLUCRE. 208. The corymb and the umbel being more or less level- topped, bringing the flowers into a horizontal plane or a con- vex form, the ascending order of development appears as Cen- tripetal. That is, the flowering proceeds from the margin or circumference regularly towards the centre; the lower flowers of the former answering to the outer ones of the latter. 209. In these three kinds of flower-clusters, the flowers are raised on conspicuous pedicels (204) or stalks of their own. The shortening of these pedicels, so as to render the flowers sessile or nearly so, converts a raceme into a Spike, and a corymb or an umbel into a Head. 210. A Spike is a flower-cluster with a more or less length- ened axis, along which the flowers are sessile or nearly so ; as in 801 the Plantain (Fig. 204). 211. A Head (Capitulum) is a round or roundish cluster of flowers, Pio. 201. A raceme. 202. A corymb. 203, An umbel. FIQ. 204. Spike of the common Plantain or Ribwort.

It is just what a spike would become if its axis were shortened ; or an umbel, if its pedicels were all shortened until the flowers became sessile. The head of the Button-b:ish is naked ; but that of the Thistle, of the Dandelion, and the like, is surrounded by empty bracts, which form an Involucre. Two particular forms of the spike and the head have received particular name?, namely, the S$adix and the Catkin. 212. A Spadix is a fleshy spike or head, with small and often imperfect flowers, as in the Calla, Indian Turnip, (Fig. 206), Sweet Flag, etc. It is commonly surrounded or embraced by a peculiar enveloping leaf, called a SPATHE. 213. A Catkin, or Ament, is the name given to the scaly sort of spike of the Birch (Fig. 207) and Alder, the Willow and Poplar, and one sort of flower-clusters of the Oak, Hickory, and the like, the so-called Amen- taceous trees. 214. impound flower-clusters of these kinds are not uncommon. When the stalks which in the sim- ple umbel are the pedicels of single flowers themselves branch into an umbel, a Compound Umbel is formed. FIQ. 205. Head of the Button-bush (Cephalanthns). FIG. 206.

This is the inflorescence of Caraway (Fig. 208), Parsnip, and almost all of the great family of Umbelliferous (umbel-bearing) plants. 215. The second- ary or partial umbels of a compound um. bel are UMBELLETS. When the umbellets are subtended by an involucre, this sec- ondary involucre is called an IKVOLTJCEL. 216. A Compound raceme is a cluster of racemes racemosely arranged, as in Smilacina racemosa. A compound corymb is a corymb some branches of which branch again in the same way, as in Mountain Ash. A compound spike is a spicately disposed cluster of spikes. 217. A Panicle, such as that of Oats and many Grasses, is a compound flower-cluster of a more or less open sort which branches with apparent irregularity, neither into corymbs nor racemes. Tig. 209 repre- sents the simplest panicle. It is, as it were, a raceme of which some of the pedicels have branched so as to bear a few flowers on pedicels of their own, while others remain simple. A compound panicle is one that branches in this v 7 ay again and again. 218. Determinate Inflorescence is that in which the flowers are from terminal buds. The simplest case is that of a solitary terminal flower, as 212 in Fig. 210. This stops the growth of the stem ; for its terminal bud, be- coming a blossom, can no more lengthen in the manner of a leaf-bud. Any FIG. 208. Compound Umbel of Caraway. FIG. 209.

If such branches are leafy shoots, at length terminated by single blossoms, the inflorescence still consists of solitary flowers at the summit of stem and branches. But if the flowering branches bear only bracts in place of ordi- nary leaves, the result is the kind of flower-cluster called 219. A Cyme. This is commonly a flat-topped or convex flower-cluster, like a corymb, only the blossoms are from terminal buds. ... Fig. 211 illustrates the simplest cyme in a plant with oppo- ^ i/5 /*& site leaves, namely, with three flowers. The middle flower, y j^ a, terminates the stem ; the two others, b b, terminate branches, \ / one from the axil of each of the uppermost leaves ; and being later than the middle one, the flowering proceeds from the centre outwards, or is Centrifugal. This is the opposite of the indeterminate mode, or that where all the flower-buds are axillary. If flowering branches appear from the axils below, . the lower ones are the later, so that the order of blossoming K\ continues centrifugal or, which is the same thing, descending, ^ as in Fig. 213, making a sort of reversed raceme we false ra- ceme, a kind of cluster which is to the true raceme just what the flat cyme is to the corymb. 220. Wherever there are bracts or leaves, buds may be 213 produced from their axils and appear as flowers. Fig. 212 represents the case where the brandies, b b, of Fig. 211, each with a pair of small leaves or bracts about their middle, have branched again, and produced the brauchlets and flowers c <?, on each side. It is the continued repetition of this which forms the full or compound cyme, such as that of the Laures- tiuus, Hobble-bush, Dogwood, and Hydrangea (Fig. 214). 221. A Fascicle (meaning a bundle), like that of the Sweet William and Lychnis of the gardens, is only a cyme with the flowers much crowded. 222. A Glomerule is a cyme still more compacted, so as to imitate a head. It may be known from a true head by the flowers not expanding centripetally, that is, not from the circumference towards the centre. 223. The illustrations of determinate or cymose inflorescence have been taken from plants with opposite leaves, which give rise to the most regular cymes. But the Rose, Cinque foil, Buttercup, etc., with alternate leaves, furnish also good examples of cymose inflorescence. 224. A Cymule (or diminutive cyme) is either a reduced small cyme of few flowers, or a branch of a compound cyme, i. e. a partial cyme. 225. Scorpioid or Helicoid Cymes, of various sorts, are forms of de- terminate inflorescence (often puzzling to the student) in which one half of the ramification fails to appear. So that they may be called incomplete cymes. The commoner forms may be understood by comparing a complete FIG. 213.

These distinctions between determinate and indeterminate inflores- cence, between corymbs and cymes, and between the true and the false raceme and spike, were not recognized by botanists much more than half a century ago, and even now are not always attended to in descriptions. It is still usual and convenient to describe rounded or flat-topped and open ramification as corymbose, even when essentially cymose; also to call the reversed or false racemes or spikes by these (strictly incorrect) names. 227. Mixed Inflorescence is that in which the two plans are mixed or combined in compound clusters. A mixed panicle is one in which, while the primary ramification is of the indeterminate order, the secondary or ultimate is wholly or partly of the determinate order. A contracted or elongated inflorescence of this sort is called a THYRSUS. Lilac and Horse- chestnut afford common examples of mixed inflorescence of this sort. When loose and open such flower-clusters are called by the general name of Panicles. The heads of Composite are centripetal; but the branches 01 peduncles which bear the heads are usually of centrifugal order. 2. PARTS OE ORGANS OF THE FLOWER, 228. These were simply indicated in Section II. 16. Some parts are necessary to seed-bearing ; these are Essential Organs, namely, the Stamens and Pistils. Others serve for protection or for attraction, often for both. Such are the leaves of the Flower, or the Floral Envelopes. 229. The Floral Envelopes, taken together, are sometimes called the PERIANTH, also Perigone, in Latin form Perigonium. In a flower which possesses its full number of organs, the floral envelopes are of two kinds, namely, an outer circle, the CALYX, and an inner, the COROLLA. 230. The Calyx is commonly a circle of green or greenish leaves, but not always. It may be the most brightly colored part of the blossom. Each calyx-leaf or piece is called a SEPAL. 231. The Corolla is the inner circle of floral envelopes or flower-leaves, usually of delicate texture and colored, that is, of some other color than 'green. Each corolla-leaf is called a PETAL. 232. There are flowers in abundance whhAi consist wholly of floral envel- opes. Such are the so-called full double flowers, of which the choicer roses and camellias of the cultivator are familiar examples. In them, under the gardener's care and selection, petals have taken the, place of both stamens and pistils. These are monstrous or unnatural flowers, incapable of pro- ducing seed, and subservient only to human gratification. Their common name of double flowers is not a sensible one : except that it is fixed by custom, it were better to translate their Latin name, flores pleni, and call them full flowers, meaning full of leaves. 233. Moreover, certain plants regularly produce neutral flowers, consist- ing of floral envelopes only. In Fig. 214, some are seen around the margin 80 FLOWERS. [SECTION 8. of the cyme in Hydrangea. They are likewise familiar in the Hobble-bush and in Wild-Cranberry tree, Viburnum Oxycoccus ; where they form an attractive setting to the cluster of small and comparatively inconspicuous perfect flowers which they adorn. In the Guelder Rose, or Snow-ball of ornamental cultivation, all or most of the blossoms of this same shrub are transformed into neutral flowers. 234. The Essential Organs are likewise of two kinds, placed one above or within the other ; namely, first, the STAMENS or fertilizing organs, and second, the PISTILS, which are to be fertilized and bear the seeds. 235. A Stamen consists of two parts, namely, the FILAMENT or stalk (Fig. 219 a), and the ANTHER (4). The latter is the only essential part. It is a case, commonly with two lobes or cells, each opening lengthwise by a slit, at the proper time, and discharging a powder or dust- like substance, usually of a yellow color. This powder is the POLLEN, 01 fertilizing matter, to produce which is the office of the stamen. 236. A Pistil (Fig. 220, 221) when complete, has three parts; OVARY, STYLE, and STIGMA. The Ovary, at base, is the hollow portion, which con- tains one or more OVULES or rudimentary seeds. The Style is the tapering Fia. 218. Kflosplenus, namely, a full double flower of Rose. Fio. 219.

SECTION 8.] PLAN OF THE FLOWER. 81 portion above : the Stigma is a portion of the style, usually its tip, with moist naked surface, upon which grains of pollen may lodge and adhere, and thence make a growth which ex- tends down to the ovules. When there is no style then the stigma occupies the tip of the ovary. 237. The Torus or Receptacle is the end of the flower-stalk, or the portion of axis or stem out of which the several organs of the flower grow, upon which they are borne (Fig. 223). 238. The parts of the flower are thus disposed on the receptacle or axis essentially as are leaves upon a very short stem ; first the sepals, or outer floral leaves ; then the petals or inner floral leaves ; then the stamens ; lastly, at summit or centre, the pistils, when thtere are two or more of them, or the single pistil, when only one. Fig. 223 shows the organs displayed, two of each kind, of such a simple and symmetrical flower as that of a Sedum or Stonecrop, Fig. 222. 221 3. PLAN OF FLOWER. 239. All flowers are formed upon one general plan, but with almost In- finite variations, and many disguises. This common plan is best understood by taking for a type, or standard for comparison, some perfect, complete, regular, and symmetrical blossom, and one as simple as such a blossom could well be. Flowers are said to be Perfect (hermaphrodite), when provided with both kinds of essential or- gans, i. e. with both stamens and pistils. Complete, when, besides, they have the two sets of floral envelopes, namely, FIG. 221. Model of a simple pistil, with ovary cut across and slightly opened ventrally, to show the ovules and their attachment.' FIG. 222. Flower of Sedum ternatnm, a Stonecrop. FIG. 223. Parts of same, two of each kind, separated and displayed ; the torus or receptacle in the centre; a, a sepal ; b, a petal; c, a stamen ; d, a pistil. 82 FLOWERS- [SECTION 8. calyx, and corolla. Such are completely furnished with all that belongs to a flower. Regular, when all the parts of each set are alike in shape and size. Symmetrical, when there is an equal number of parts in each set or circle of organs. 240. Flax-flowers were taken for a pattern in Section II. 16. But in them the five pistils have their ovaries as it were consolidated into one body. Sedum, Fig. 222, has the pistils and all the other parts free from such combination. The flower is perfect, complete, regular, and symmetrical, but is not quite as simple as it might be ; for there are twice as many stamens as there are of the other organs. Crassula, a relative of Sedum, cultivated in the conservatories for winter blossoming (Fig. 224) is simpler, being isostemonous, or with just as many stamens as petals or sepals, while Sedum is diplostemonous, having double that number : it has, indeed, two sets of stamens. 241. Numerical Plan. A certain number either runs through the flower or is discernible in some of its parts. This number is most commonly either five or three, not very rarely four, occasionally two. Thus the ground-plan of the flowers thus far used for illus- tration is five. That of Trillium (Fig. 226, 227) is three, as it likewise is as really, if not as plainly, in Tulips and Lilies, Crocus, Iris, and all that class of blossoms. In some Sedums all the flowers are in fours. In others the first flowers are on the plan of five, the rest mostly on the plan of four, that is, with four sepals, four petals, eight stamens (i. e. twice four), and four pis- tils. Whatever the ground number may be, it runs through the whole in symmet- rical blossoms. 242. Alternation of the successive Circles. In these flowers the parts of the successive circles alternate ; and such is the rule. That is, FIG. 224. Flower of a Crassula. 225. Diagram or ground-plan of same. FIG. 226. Flower of a Trillium ; its parts in threes. FIG. 227. Diagram of flower of Trillium. In this, as in all such diagrams of cross- section of blossoms, the parts of the outer circle represent the calyx ; the next, co- rolla; within, stamens (here in two circles of three each, and the cross-section is through the anthers) ; in the centre, section of three ovaries joined into a compound sne of three cells SECTION 8.] PLAN OF THE FLOWER. 83 the petals stand over the intervals between the sepals ; the stamens, when of the same number, stand over the intervals between the petals ; or when twice as mauy, as in the Trillium, the outer set alternates with the petals, and the inner set, alternating with the other, of course stands before the petals; and the pistils alternate with these. This is just as it should be 011 the theory that the circles of the blossom answer to whorls of leaves, which alternate in this way. While in such flowers the circles are to be regarded as whorls, in others they are rather to be regarded as condensed spirals of alternate leaves. But, however this may be, in the mind of a morphological botanist, 243. Flowers are altered Branches, and their parts, therefore, altered leaves. That is, certain buds, which might have grown and lengthened into a leafy branch, do, under other circumstances and to accomplish other purposes, develop into blossoms. In these the axis remains short, nearly as it is in the bud ; the leaves therefore remain close together in sets or circles ; the outer ones, those of the calyx, generally partake more or less of the character of foliage ; the next set are more delicate, and form the co- rolla, while the rest, the stamens and pistils, appear under forms very dif- ferent from those of ordinary leaves, and are concerned in the production of seed. This view gives to Botany an interest which one who merely no- tices the shape and counts the parts of blossoms, without understanding their plan, has no conception of. 244. That flowers answer to branches may be shown, first, from their position. As explained in the section on Inflorescence, flowers arise from the same places as branches, and from no other ; flower-buds, like leaf-buds, appear either on the summit of a stem, that is, as a terminal bud, or in the axil of a leaf, as an axillary bud. And, as the plan of a symmetrical flower shows, the arrangement of the parts on their axis or receptacle is that ol leaves upon the stem. 245. That the sepals and petals are of the nature of leaves is evident from their appearance ; they are commonly called the leaves of the flower. The calyx is most generally green in color, and foliaceous (leaf-like) in texture. And though the corolla is rarely green, yet neither are proper leaves always green. In our wild Painted-cup, and in some scarlet Sages, common in gardens, the leaves just under the flowers are of the brightest red or scarlet, often much brighter-colored than the corolla itself. And sometimes (as in many Cactuses, and in Carolina Allspice) there is such a regular gradation from the last leaves of the plant (bracts or bractlets) into the leaves of the calyx, that it is impossible to say where the one ends and the other begins. If sepals are leaves, so also are petals ; for there is no clearly fixed limit between them. Not only in the Carolina Allspice and Cactus (Tig. 229), but in the Water-Lily (Fig. 228) and in a variety of flowers with more than one row of petals, there is such a complete transi- tion between calyx and corolla that no one can surely tell how many of the leaves belong to the one and how many to the other. 84 FLOWERS. [SECTION 8. 246. That stamens are of the same general nature as petals, and there- fore a modification of leaves, is shown by the gradual transitions that ocfcui between the one and the other in many blos- soms ; especially in cul- tivated flowers, such as Roses and Camelh'as, when they begin to double, that is, to change their stamens into pet- als. Some wild and natural flowers show the same interesting transitions. The Caro- lina Allspice and the White Water-Lily ex- hibit complete grada- tions not only between sepals and petals, but between petals and stamens. The sepals of our Water-Lily are green out- side, but white and petal-like on the inside ; the petals, in many rows, gradually grow narrower towards the centre of the flower ; some of these are tipped with a trace of a yellow anther, but still are petals; the next are more contracted and sta- men-like, but with a flat petal-like filament; and a further narrow- ing of this completes the genuine stamen. 247. Pistils and stamens now and then change into each other in some Willows; pistils often turn into petals in cultivated flowers; and in the Double Cherry they are occasionally replaced by small green leaves. Sometimes a whole blossom changes into a cluster of green leaves, as in the "green roses " occasionally noticed in gar- dens, and sometimes it degenerates into a leafy branch. So the botanist regards pistils also as answering to leaves ; that is, to single leaves when simple and separate, to a whorl of leaves when conjoined. Fio. 228. Series of sepals, petals, and stamens of White Water-Lily, showing the transitions. fto.229. A Cactus blossom. SECTION 8.J MODIFICATIONS OF THE TYPE. 4. MODIFICATIONS OF THE TYPE. 248. The Deviations, as they may be called, from the assumed type or pattern of flower are most various and extensive. The differences between one species and another of the same genus are comparatively insignificant ; those between different genera are more striking ; those between different families and classes of plants more and more profound. They represent different adaptations to conditions or modes of life, some of which have" obvious or probable utilities, although others are beyond particular expla- nation. The principal modifications may be conveniently classified. Eirst those which in place of perfect (otherwise called hermaphrodite or bisexual) flowers, give origin to 249. Unisexual, or Separated, or Diclinous Flowers, imperfect flow- ers, as they have been called in contradistinction to perfect flowers ; but that term is too ambiguous. In these some flowers want the stamens, while others want the pistils. Taking hermaphrodite flowers as the patteru, it is natural to say that the missing organs are suppressed. This expression is justified by the very numerous cases in which the missing parts are abortive, that is, are represented by rudiments or vestiges, which serve to exemplify the plan, although useless as co office. Unisexual flowers are Monoecious (or Monoicous, i. e. of one household), when flowers of both sorts or sexes are produced by the same individual plant, as in the Ricinus or Castor-oil Plant, Fig. 230. Dioecious (or Dioicous, i. e. of separate households), when the two kinds are borne on different plants ; as in Willows, Poplars, Hemp, and Moon- seed, Fig. 231, 232. Polygamous, when the flowers are some of them perfect, and some staminate or pistillate only. Fio. 230. Unisexual flowers of Castor-oil plant : s, staminate flower ; p, pistillate flower. FIQ. 231, staminate, and 232, pistillate flower of Moonseed. 86 FLOWERS, [SECTION 8. 250. A blossom having stamens and no pistil is a Staminate or Male flower. Sometimes it is called a Sterile flower, not appropriately, for other flowers may equally be sterile. One having pistil but no stamens is a Pistillate or Female flower. 251. Incomplete Flowers are so named in contradistinction to complete : they waut either one or both of the floral envelopes. Those of Fig. 230 are incomplete, having ca- lyx but no corolla. So is the flower of Anem- one (Fig. 233), although its calyx is colored like a corolla. The flowers of Saururus orLizard's-tail, although perfect, have neither calyx nor corolla (Fig. 234). Incomplete flowers, accordingly, are Naked or Achlamydeous, destitute of both floral en- velopes, as in Fig. 234, or dpetalow, when wanting only the corolla. The case of corolla present and calyx wholly wanting is extremely rare, although there are seeming instances. In fact, a single or simple perianth is taken to be a calyx, unless the absence or abortion of a calyx can be made evident. 252. In contradistinction to regular and symmetrical, very many flowers are Irregular, that is, with the members of some or all of the floral circles unequal or dissim- ilar, and Unsymmetrical, that is, when the circles of the flower or some of them differ in the num- *** of tbeir members. (Sym- metrical and unsymmetrical are Bse< ^ * n a different sense in some recent books, but the older use should be adhered to.) Want of numerical symmetry and irregularity commonly go to- gether; and both are common. Indeed, few flowers are entirely FIG. 233. Flower of Anemone Pennsylvania; apetalous, hermaphrodite. FIG. 234. Flower of Saurnrus or Lizard's- tail; naked, but hermaphrodite. FIG. 235. Flower of Mustard. 236. Its stamens and pistil separate and enlarged. FIG. 237. Flower of a Violet. 238.

SECTION 8.J MODIFICATIONS OF THE TYPE. symmetrical beyond calyx, corolla, and perhaps stamens ; and probably no irregular blossoms are quite symmetrical. 253. Irregular and Unsymmetrical Flowers may therefore be illus- trated together, beginning with cases which are comparatively free from other complications. The blossom of Mustard, and of all the very natural family which it represents (Fig. 235, 236), is regular but unsymmetrical hi the stamens. There are four equal sepals, four equal petals ; but six stamens, and only two members in the pistil, which for the present may FIG. 839. Flower of a Larkspur. 240.

These are in two circles, an outer and an inner. The outer circle consists of two stamens only; the inner has its proper number of four. The flower of Violet, which is on the plan of five, is symmetrical in calyx, corolla, and stamens, inas- much as each of these circles consists of five members ; but it is conspicu- ously irregular in the corolla, one of the petals being very different from the rest. 254. The flowers of Larkspur, and of Monkshood or Aconite, which are nearly related, are both strikingly irregular in calyx and corolla, and con- siderably unsymmetrical. In Larkspur (Pig. 239-241) the irregular calyx consists of five sepals, one of which, larger than the rest, is prolonged be- hind into a large sac or spur ; but the corolla is of only four petals (of two shapes), the fifth, needed to complete the symmetry, being left out. And the Monkshood (Fig. 242-244) has five very dissimilar sepals, and a corolla of only two very snaall and curiously-shaped petals, the three needed to make up the symmetry being left out. The stamens in both are out of symmetry with the ground-plan, being numerous. So are the pistils, which are usually diminished to three, sometimes to two or to one. 255. Flowers with Multiplication of Parts are very common. The stamens are indefinitely numerous in Larkspur and in Monkshood (Fig. 242, 243), while the pistils are fewer than the ground-plan suggests. Most Cactus-flowers have all the organs much in- creased in number (Fig. 229), and so of the Water-Lily. In Anemone (Fig. 233) the stamens and pistils are multiplied while the petals are left out. In Buttercups or Crowfoot, while the sepals and petals conform to the ground-plan of five, both stamens and pistils are indefi- nitely multiplied (Fig. 245). 256. Flowers modified by Union of Parts, so that these parts more or less lose the appearance of separate leaves or other organs growing out of the end of the stem or receptacle, are extremely common. There are two kinds of such union, namely : Coalescence of parts of the same circle by their contiguous margins; and Adnation, or the union of adjacent circles or unlike parts. 257. Coalescence is not rai-e in leaves, as in the upper pairs of Honey- suckles, Fig. 163. It may all the more be expected in the crowded circles or whorls of flower-leaves. Datura or Stramonium (Fig. 246) shows this coalescence both in calyx and corolla, the five sepals and the five petals be- ing thus united to near their tips, each into a tube or long and narrow cup. These unions make needful the following terms : FIG. 245. Flower of Ranunculus bulbosus, or Buttercup, in section. SECTION 8.] MODIFICATIONS OF THE TYPE. 89 Gamopetalous, said of a corolla the petals of which are thus coalescent into one body, whether only at base or higher. The union may extend to the very summit, as in Morning Glory and the like (Fig. 247), so that the number of petals in it may not be apparent. The old name for this was Monopetalous, but that means " one-petalled ; " while gamopetalous means " petals united," and therefore is the proper term. Polypetalous is the counterpart term, to denote a corolla of distinct, that is, separate petals. As it means " many petalled," it is not the best possible name, but it is the old one and in almost universal use. Gamosepalous applies to the calyx when the sepals are in this way united. Polysepalous, to the calyx when of sepa- rate sepals or calyx-leaves. 258. Degree of union or of separation in descriptive botany is expressed in the same way as is the lobing of leaves (139). See Fig. 249-253, and the explanations. 259. A corolla when gamopetalous com- monly shows a distinction (well marked in Fig. 249-251) between a contracted tubular portion below, the TUBE, and the spread- ing part above, the BORDER or LIMB. The junction between tube and limb, or a more or less enlarged upper portion of the tube between the two, is the THROAT. The same is true of the calyx. 260. Some names are given to partic- ular forms of the gamopetalous corolla, applicable also to a gamosepalous calyx, such as WTieel-shaped, or Rotate; when spread- ing out at once, without a tube or with a very short one, something in the shape of a wheel or of its diverging spokes, Fig. 252, 253.

Although sepals and petals are usually all blade or lamina (123), like a sessile leaf, yet they may have a contracted and stalk-like base, an- swering to petiole. This is called its CLAW, in _ ^WlT Latin Unguis. Unguicu- late petals are universal and strongly marked in the Pink tribe, as in Soapwort (Fig. 248). 262. Such petals, and various others, may have 259 260 an outgrowth of the in- ner face into an appendage or fringe, as in Soapwort, and in Silene (Fig. 259), where it is at the junction of claw and blade. This is called a CROWN, or Corona. In Passion- flowers (Fig. 260) the crown consists of numerous threads on the base of each petal. 263. Irregular Flowers may be polypetalous, or nearly so, as in the papilionaceous corolla; but most of them are irregular through coales- cence, which often much disguises the numerical symmetry also. As affecting the corolla the following forms have received particular names : 264. Papilionaceous .Corolla, Fig. 261, 262. This is polypetalous, except that two of the petals cohere, usually but slightly. It belongs only to the Leguminous or Pulse family. The name means butterfly-like; but the likeness is hardly obvious. The names of the five petals of the papilionaceous corolla are curiously incongruous. They are, FIG. 259. Unguiculate (clawed) petal of a Silene; with a two-parted crown. FIG. 260.

The STANDARD or Banner (Fexittuni), the large upper petal which is external in the bud and wrapped around the others. The WINGS (Aloe), the pair of side petals, of quite different shape from the standard. The KEEL (Carina), the two lower and usually smallest petals ; these are lightly coalescent into a body which bears some likeness, not to the keel, but to the prow of a boat ; and this encloses the stamens and pistil. A Pea-blossom is a typical example ; the present illustration is from a species of Locust, Robinia hispida. 265. Labiate Corolla (Fig. 256-258), which would more properly have been called Bilabiate, that is, two-lipped. This is a common form of gamopetalous co- rolla ; and the calyx is often bilabiate also. These flowers are all on the plan of five; and the irregularity in the corolla is owing to unequal union of the petals as well as to diversity of form. The two petals of the upper or posterior side of the flower unite with each other higher up than with the lateral petals (in Fig. 256, quite to the top), forming the Upper lip : the lateral and the lower similarly unite to form the Lower lip. The single notch which is generally found at the summit of the upper lip, and the two notches of the lower lip, or in other words the two lobes of" the upper and the three of the lower lip, reveal the real composition. So also does the alternation of these five parts with those of the calyx outside. When the calyx is also bilabiate, as in the Sage, this alternation gives three lobes or sepals to the upper and two to the lower lip. Two forms of the labiate corolla have been desig- nated, viz. : Rinffetit or Gaping, when the orifice is wide open, as in Fig. 256. .

Corolla of Catalpa laid open, displaying two good stamens abortive ones or vestiges. - SECTION 8.] MODIFICATIONS OF THE TYPB. 93 266. There are all gradations between labiate and regular corollas. In those of Gerardia, of some species of Pentstemon, and of Catalpa (Fig. 263-265), the labiate character is slight, but is manifest on close inspection, In almost all such flowers the plan of five, which is obvious or ascertain- able in the calyx and corolla, is obscured in the stamens by the abortion or suppression of one or three of their number. 267. Ligulate Corolla. The ligulate or Strap-shaped corolla mainly belongs to the family of Composite, in which numerous small flowers are gathered into a head, within an involucre that imitates a calyx. It is best exemplified in the Dandelion and in Chiccory (Fig. 266). Each one of these straps or Ligules, looking like so many petals, is the corolla of a dis- tinct flower: the base is a short tube, which opens out into the ligule : the five minute teeth at the end indicate the number of constituent petals. So this is a kind of gamopetalous corolla, which is open along one side nearly FlO. 266. Two flower-heads of Chiccory- FKk 207. One of them half rot vmj, setter Bhowlnjr ome of the flow*^ 94 FLOWERS. [SECTION 8. to the base, and outspread. The nature of such a corolla (and of the sta- mens also, to be explained in the next section) is illustrated by the flower of a Lobelia, Fig. 285. 268. In Asters, Daisies, Sunflower, Coreopsis (Fig. 268), and the like, only the marginal (or Ray) corollas are ligulate; the rest (those of- the Disk) ar* regularly gamopetalous, tubular, and five-lobed at summit ; ' but they are small and individually inconspicuous, only the ray-Jiowers making a show. In fact, those of Coreopsis and of Sunflower are simply for show, these ray-flowers being not only sterile, but neutral, that is, having neither stamens nor pistil. But in Asters, Daisies, Golden-rods, and the like, these ray-flowers are pistillate and fertile, serving therefore for seed-bearing as well as for show. Let it not be supposed tha* the show is useless. See Section XIII. 269. Actuation, or Consolidation, is the onion of the members of parts belonging to different circles of the flower (256). It is of course under- stood that in this (as likewise in coalescence) the parts are not formed and then conjoined, but are produced in union. They are born united, as the term adnate implies. To illustrate this kind of union, take the accompany, ing series of flowers (Fig. 270-274), shown in vertical section. In the first, Fig. 270, Flax-flower, there is no adnation ; sepals, petals, and sta- mens, are free as well as distinct, being separately borne on the receptacle, Dne circle within or above the next j only the five pistils have their ovaries coalescent. In Fig. 271, a Cherry flower, the petals and stamens are borne on the throat of the calyx-tube ; that is, the sepals are coalescent into a cup, and the petals and stamens are adnate to the inner face of this; in other Pio. 268.

SECTION 8.] MODIFICATIONS OF THE TYPE, 95 words, the sepals, petals, and stamens are all consolidated up to a certain height. In Fig. 272, a Purslane-flower, the same parts are adnate to or consolidated with the ovary up to its middle. In Fig. 273, a Haw- thorn-flower, the consolidation has extended over the whole ovary; and petals and stamens are adnate to the calyx still further. In Fig. 274, a Cranberry-blossom, it is the same except that all the parts are free at the same height; all seem to arise from the top of the ovary. 270. In botanical description, to express tersely such differences in the relation of these organs to the pistil, they are said to be Hypogynous (i. e. under the pis- til) when they are all/ra?, that is, not adnate to pistil nor connate with each other, as in Fig. 270. Perigynous (around the pistil) when couuate with each other, that is, when petals and stamens are inserted or borne on the calyx, whether as in Cherry -flowers (Fig. 271) they are free from the pistil, or as in Purslane and Hawthorn (Fig, 272, 273) they are also ad- nate below to the ovary. Epigynous (on the ovary) when so adnate that all these parts ap- pear to arise from the very summit of the ovary, as in Fig. 274. The last two terms are not very definitely distinguished. 271. Another and a simpler form of expression is to describe parts of the flower as being Free, when not united with or inserted upon other parts. Distinct, when parts of the same kind are not united. This term is the counterpart of coalescent, as free is the counterpart of adnate. Many writers use the term " free " indiscriminately for both ; but it is better to distinguish them. FIG. 270 Flax-flower in section; the parts all free, hypogyuous. FIG. 271. Cherry-flower in section; petals and stamens adnate to tube of calyx, perigynous. FIG. 272. Purslane-flower in section; calyx, petals, stamens, all adnate to lower half of ovary, perigynous. FLOWERS. [SECTION 8. Connate is a term common for either not free or not distinct, that is, foi parts united congenitally, whether of same or of different kinds. Adnate, as properly used, relates to the union of dissimilar parts. 272. In still another form of ex- pression, the terms superior and inferior have been much used in the sense of above and below. Superior is said of the ovary of Flax-flower, Cherry, etc., because above the other parts ; it is equiv- alent to "ovary free." Or it is said of the calyx, etc., when above the ovary, as in Eig. 273-275. Inferior, when applied to the ovary, means the same as " calyx adnate ; " when applied to the flo- ral envelopes, it means that they are free. 273. Position of Flower or of its Parts. The terms superior and inferior, or upper and lower, are also used to indicate the relative position of the parts of a flower in reference to the axis of inflorcs- An axillary flower stands between the bract or leaf which sub- tends it and the axis or stem which bears this bract or leaf. This is represented in sectional diagrams (as in ig. 275, 276) by a transverse line for the bract, and a small circle for the axis of inflorescence. Now the side of the blossom which faces the bract is the Anterior, or Inferior, or Lower side ; while the side next the axis is the Posterior, or Superior, or Upptr side of the flower. 274. So, in the labiate corolla (Fig. 256-258), the lip which is composed of three of the five petals is the anterior, or inferior, or lower lip; the other is the posterior, or superior^ or upper lip.

SECTION 8.] ARRANGEMENTS IN THE BUD. 97 975. In Violets (Fig. 238, 276), the odd sepal is posterior (next the axis) ; the odd petal is therefore anterior, or next the subtending leaf. In the papilionaceous flower (Fig. 261, and diagram, Fig. 275), the odd sepal is anterior, and so two sepals are posterior; consequently, by the alternation, the odd petal (the standard) is posterior or upper, and the two petals form- ing the keel are anterior or lower. 5. ARRANGEMENT OP PARTS IN THE BUD. 276. -Estivation was the fanciful name given by Linnaeus to denote the disposition of the parts, especially the leaves of the flower, before An- thesis, i. e. before the blossom opens. Prafloration, a better term, is some- times used. This is of importance in distinguishing different families or genera of plants, being generally uniform in each. The aestivation is best seen by making a slice across the flower-bud ; and it may be expressed in diagrams, as in the accompanying figures. 277. The pieces of the calyx or the corolla either overlap each other in the bud, or they do not. When they do not overlap, the aestivation is Vahate, when the pieces meet each other by their abrupt edges, without any infolding or overlapping; as the calyx of the Linden or Basswood (Fig. 277). Induplicate, which is valvate with the margins of each piece projecting inwards, as in the calyx of a common Virgin's-bower, Fig. 278, or Involute, which is the same but the margins rolled y^_ _// inward, as in most of the large-flowered species of 377 """ Clematis, Fig. 279. Reduplicate, a rarer modification of valvate, is similar but with margins projecting outward. Open, the parts not touching in the bud, as the calyx of Mignonette. 278. When the pieces overlap in the bud, it is in one of two ways ; either every piece has one edge in and one edge out, or some pieces are whdly outside and others wholly inside. In the first case the estivation is Convolute, also named Contorted or Twisted, as in Fig. 280, a cross-sec- tion of a corolla very strongly thus convolute or rolled up together, and in the corolla of a Flax-flower (Fig. 281), where the petals only moderately overlap in this way. Here one edge of every petal covers the next before Pio. 277. Diagram of a flower of Linden, showing the calyx valvate and corolla imbricate in the bud, etc. FIG. 278.

[SECTION 9. ft, while its other edge is covered by the next behind it The other mode is the Imbricate or Imbricated, in which the outer parts cover or overlap the inner so as to "break joints," like tiles or shingles on a roof ; whence the name. When the parts are three, the first, or outermost is wholly external, the third wholly internal, the second has one margin covered by the first while the other overlaps the third or innermost piece: this is the arrangement of alternate three- ranked leaves (187). When there are five pieces, as in the corolla of Fig. 825, and calyx of Fig. 281, as also of Fig. 241, 276, two are external, two are internal, and one (the third in the spiral) has one edge covered by the outermost, while its other edge covers the in- nermost; which is just the five-ranked arrangement of alternate leaves (188). When the pieces are four, two are outer and two are inner; which answers to the ar- rangement of opposite leaves. 279. The imbricate and the convolute modes some- times vary one into the other, especially in the corolla. 280. In a gamopetalous corolla or gamosepalons calyx, the shape of the tube in the bud may sometimes be notice- able. It may be Plicate or Plaited, that is, folded lengthwise; and the plaits may either be turned outwards, forming projecting ridges, as in the corolla of Campanula; or turned in- wards, as in that of Gentian Belladonna ; or Supervolvte, when the plaits are convolutely wrapped round each other, as in the corolla of Morning Glory and of Stramonium, Fig. 882. SECTION IX. STAMENS IN PARTICULAR. 881. Androecium is a technical name for the staminate system of flower (that is, for the stamens taken together), which it is sometimes con- venient to use. The preceding section has dealt with modifications of the flower pertaining mainly to calyx and corolla. Those relating to the sta- mens are now to be indicated. First as to Pio. 280.

The stamens usually go with the petals. Not rarely they are at base Epipetalous, that is, inserted on (or adnate to) the corolla, as in Tig. 283. When free from the corolla, they may be Hypogynous, inserted on the receptacle under the pistil or gynoecium. Perigynous, inserted on the calyx, that is, with the lower part of filament adnate to the calyx-tube. Epigynous, borne apparently on the top of the ovary ; all which is ex- plained in Fig. 270-274. Grynandrous is another term relating to insertion of rarer occurrence, that is, where the stamens are inserted on (in other words, adnate to) the style, as in ^ Lady's Slipper (Fig. 284), and in the Orchis family generally. 283. In Relation to each Other, stamens are more com- monly Distinct, that is, without any union with each other. But when united, the following technical terms of long use 285 indicate their modes of mutual connection : Monadelphous (from two Greek words, meaning " in one brotherhood "), when united by their filaments into one set, usually into a ring or cup below, or into a tube, as in the Mallow Family (Fig. 286), the Passion- flower (Fig. 260), the Lupine (Fig. 287), and in Lobelia (Fig. 285). Diadelphous (meaning in two brotherhoods), when united by the fila- ments into two sets, as in the Pea and most of its near relatives (Fig. 288), usually nine in one set, and one in the other. Triadelphous (three brotherhoods), when the filaments are united in three sets or clusters, as in most species of Hypericum. FIG. 283.

Pentadelphous (five brotherhoods), when in five sets, as in some species of Hypericum and in American Linden (Fig. 277, 289). Polyadelphous (many or several brotherhoods) is the term generally employed when these sets are several, or even more than two, and the par- ticular number is left unspecified. These terms all relate to the fila- ments. Syngenesious is the term to denote that stamens have their anthers united, coalesceut into a ring or tube ; as in Lobelia (Fig. 285), in Violets, and hi all of the great family of Compositse. 284. Their Number in a flower is commonly expressed directly, but sometimes adjectively, by a series of terms which were the name of classes in the Linnsean artificial system, of which the following names, as also the preceding, are a survival -. Monandrous, i. e. solitary-stamened, when the flower has only one stamen, Diandrous, when it has two stamens only, Triandrous, when it has three stamens, Tetrandrous, when it has four stamens, Pentandrous, when it has five stamens, Hexandrous, when with six stamens, and so on to Polyandrous, when it has many stamens, or more than a dozen. 285. For which terms, see the Glossary. They are all Greek numerals prefixed to -andria (from the Greek), which Linnseus used for andrcecium, and are made into an English adjective, -androus. Two other terms, of same origin, designate particular cases of number (four or six) in con- nection with unequal length. Namely, the stamens are Didynamous, when, being only four, they form two pairs, one pair longer than the other, as in the Trumpet Creeper, in Gerardia (Fig. 263), etc. FIG. 286.

SECTION 9-3 ANTHERS. 101 Tetradynamous, when, being only six, four of them surpass the other two, as iu the Mustard-flower and all the Cruciferous family, Fig. 235. 286. The Filament is a kind of stalk to the anther, commonly slender or thread-like : it is to the anther nearly what the petiole is to the blade of a leaf. Therefore it is not an essential part. As a leaf may be without a stalk, so the anther may be Sessile, or without a filament. 287. The Anther is the essential part of the stamen. It is a sort of case, tilled with a One powder, the Pollen, which serves to fertilize the pis- til, so that it may perfect seeds. The antber is said to be Innate (as in Fig. 292), when it is attached by its base to the very apex of the filament, turning neither inward nor outward; Adnate (us in Fig. 293), when attached as it were by one face, usually for its whole length, to the side of a continuation of the filament ; and Versatile (as in Fig. 291), when fixed by or near its middle only to the very point of the filament, so as to swing loosely, as in the Lily, in Grasses, etc. Versatile or ad- nate anthers are Introrse, or Incumbent, when facing in- ward, that is, toward the centre of the flow- ^ 2 93 294 er, as in Magnolia, Water-Lily, etc. Extrorse, when facing outwardly, as in the Tulip-tree. 288. Rarely does a stamen bear any resemblance to a leaf, or even to a petal or flower-leaf. Nevertheless, the botanist's idea of a stamen is that it answers to a leaf developed in a peculiar form and for a special purpose. In the filament he sees the stalk of the leaf; in the anther, the blade. The blade of a leaf consists of two similar sides ; so the anther consists of two LOBES or CELLS, one answering to the left, the other to the right, side of the blade. The two lobes are often connected by a prolongation of the filament, which answers to the midrib of a leaf ; this is called the CONNECTIVE. This is conspicuous in Fig. 292, where the connective is so broad that it separates the two cells of the anther to some distance. 289. A simple conception of the morphological relation of an anther to a leaf is given in Fig. 295, an ideal figure, the lower part rep- resenting a stamen with the top of its anther cut away; the upper, the corresponding upper part of a leaf. FIG. 292. Stamen of Isopyrum, with innate anther. 293. Of Tulip-tree, with adnate (and extrorse) anther. 294. Of Evening Primrose, with versatile anther. FIG. 295. Diagram of the lower part of an anther, cut across above, and the upper part of a leaf, to show how the one answers to the other; the filament to petiole, the connective to midrib; the two cells to the right and left halves of the blade. 102 STAMENS. [SECTION 9, 890. So anthers are generally two-celled. But as the pollen begins to form in two parts of each cell (the anterior and the posterior), sometimes these two strata are not confluent, and the anther even at maturity may be four-celled, as in Moonseed (Fig. 296) ; or rather, in that case (the word cell being used for each lateral half of the PF\ ^fiS& r ^\ or S an )> ifc fa to- celled > but the cells bikcel- LD /\ y/M^ late. 291. But anthers may become one-celled, and that either by confluence or by suppres- sion. 292. By confluence, when the two cells run together into one, as they nearly do in most species of Pentstemou (Fig. 297), more so in Monarda (Fig. 300), and completely in the Mallow (Fig. 298) and all the Mallow family. 3ns 804 FIG. 296.

SECTION 9.] POLLEN. 103 293. By suppression ih certain cases the anther may be reduced to one cell or halved. In Globe Amaranth (Fig. 299) there is a single cell without vestige of auy other. Different species of Sage and of the White Sages of California show various grades of abortion of one of the anther-cells, along with a singular lengthening of the connective (Fig. 302-305). 294-. The splitting opeu of an anther for the discharge of its pollen is termed its Dehiscence. 295. As the figures show, this is commonly by a line along the whole length of each cell, either lateral or, when the anthers are extrorse, often along the outer face, and when introrse, along the inner face of each cell. Some- times the opening is only by a chink, hole, or pore at the top, as hi the Azalea, Py- rola (Fig. 307), etc. ; sometimes a part of the face separates as a sort of trap-door (or valve), hinged at the top, and open- ing to allow the escape of the pollen, as in the Sassafras, Spice-bush, and Barberry (Fig. 308). 296. Pollen, This is the powdery matter, commonly of a yeflow color, which fills the cells of the anther, and is discharged during blossoming, 809 810 811 812 818 after which the stamens generally fall or wither away. Under the micro- scope it is found to consist of grains, usually round or oval, and all alike in the same species, but very diiferent in different plants. So that the Q.Q 314 315 316 817 818 plant may sometimes be recognized from the pollen alone. Several forms are shown in the accompanying figures. FIG. 306.

An ordinary pollen-grain has two coats; the outer coat ehickish, but weak, and frequently adorned with lines or bands, or studded with points ; the inner coat is extremely thin and delicate, but extensible, and its cavity when fresh contains a thickish protoplasmic fluid, often rendered turbid by an immense number of minute particles that float in it. As the pollen matures this fluid usually dries up, but the protoplasm does not lose its vitality. When the grain is wetted it absorbs water, swells up, and is apt to burst, discharging the contents. But when weak syrup is used it absorbs this slowly, and the tough in- ner coat will sometimes break through the outer and begin a kind of growth, like that which takes place when the pollen is placed upon the stigma. 298. Some pollen - grains are, as it were, lobed (as in Fig. 315, 316), or formed of four grains united (as in the Heath family, Fig. 317) : that of Pine (Fig. 318) has a large rounded and empty bladder-like expansion upon each side. This renders such pollen very buoyant, and capable of being trans- ported to a great distance by the wind. 299. In species of Acacia simple grains lightly cohere into globular pellets.

ANGIOSPERMOUS OB ORDINARY GYNCECIUM. 300. Gynoecium is the technical name for the pistil or pistils of a flower taken collectively, or for whatever stands in place of these. The various modifications of the gyucecium and the terms which relate to them require particular attention. 301. THE- PISTIL, when only one, occupies the centre of the flower ; when there are two pistils, they stand facing each other in the centre of the flower ; when several, they commonly form a ring or circle ; and when very numerous, they are generally crowded in rows or spirals on the sur- face of a more or less enlarged or elongated receptacle. Their number gives rise to certain terms, the counterpart of those used for stamens (284), which are survivals of the names of orders in the Linnsean artificial system. The names were coined by prefixing Greek numerals to -gynia used for gynoecium, and changed into adjectives in the form of -gynous. That is, a flower is Monogynous, when it has a single pistil, whether that be simple or com- pound ; Digynous, when it has only two pistils ; Trigynous, when with three ; Tetragynous, with four ; Pentagynous, with five ; Hexagynous, with six ; and so on to Polygynous, with many pistils. 302. The Parts of a Complete Pistil, as already twice explained (16, 236), are the OVARY, the STYLE, and the STIGMA. The ovary is one es- sential part: it contains the rudiments of seeds, called OVULES. The stigma at the summit is also essential : it receives the pollen, which fer- tilizes the ovules in order that they may become seeds. But the style, commonly a tapering or slender column borne on the summit of the ovary, and bearing the stigma on its apex or its side, is no more necessary to a pistil than the filament is to the stamen. Accordingly, there is no style in many pistils : in these the stigma is sessile, that is, rests directly on the ovary (as in Fig. 326). The stigma is very various in shape and appear- ance, being sometimes a little knob (as in the Cherry, Fig. 271), sometimes a point or small surface of bare tissue (as in Fig. 327-330), and sometimes a longitudinal crest or line (as in Fig. 324, 341-343), or it may occupy the whole length of the style, as in Fig. 331. 303. The word Pistil (Latin, Pistilluni) means a pestle. It came into use in the first place for such flowers as those of Crown Imperial, or Lily, in which the pistil in the centre was likened to the pestle, and the perianth around it to the mortar, of the apothecary. 304. A pistil is either simple or compound. It is simple when it answers to a single flower-leaf, compound when it answers to two or three, or a fuller circle of such leaves conjoined. 106 SIMPLE PISTILS. [SECTION 10. 305. Carpels. It is convenient to have a name for each flower-leaf of the gyucecium ; so it is called a Carpel, in Latin Carpellum or Carpidium. A simple pistil is a carpel. Each component flower-leaf of a compound pistil is likewise a carpel. When a flower has two or more pistils, these of course are simple pistils, that is, separate carpels or pistil-leaves. There may be only a single simple pistil to the flower, as in a Pea or Cherry blossom (Eig. 271) ; there may be two such, as in many Saxifrages ; or many, as in the Strawberry. More commonly the single pistil in the centre of a blossom is a compound one. Then there is seldom much difficulty in ascertaining the number of carpels or pistil-leaves that com- pose it. 306. The Simple Pistil, viewed morphologically, answers to a leaf, blade with margins incurved and united where they meet, so forming a closed case or pod (the ovary), and bearing ovules at the suture or junction of these margins : a tapering upper portion with margins similarly inrolled, is supposed to form the style ; and these same margins, exposed at the tip or for a portion of the length, become the stigma. Compare, under this view, the three accompanying figures. 307. So a simple pistil should have a one-celled ovary, only one line of attachment for the ovules, a single style, and a single stigma. Certain variations from this normal condition which some- times occur do not invalidate this mor- phological conception. For instance, the stigma may become two-lobed or two- ridged, because it consists of two leaf- margins, as Fig. 324- shows; it may become 2-locellate by the turning or grow- ing inward of one of the sutures, so as to divide the cavity. 308. There are two or three terms which primarily relate to the parts of a simple pistil or carpel, and are thence carried on to the compound pistil, viz. : VENTRAL SUTURE, the line which answers to the united margins of the carpel-leaf, therefore naturally called a suture or seam, and the ventral or inner one, because in the circle of carpel-leaves it looks inward or to the centre of the flower. DORSAL SUTURE is the line down the back of the carpel, answering to FIG. 323. An inrolled small leaf, such as in double-flowered Cherry blossoms is often seen to occupy the place of a pistil. FIG. 324. A simple pistil (of Isopyrum), with ovary cut across ; the inner (ven- tral) face turned toward the eye : the ovules seem to be borne on the ventral suture, answering to leaf-margins : the stigma above seen also to answer to leaf-margins.

SECTION 10.] PISTILS. 107 the midrib of the leaf, not a seam therefore ; but at maturity many fruits, such as pea-pods, open by this dorsal as well as by the ventral line. PLACENTA, a name given to the surface, whatever it be, which bears the ovules and seeds. The name may be needless when the ovules grow directly on the ventral suture, or from its top or bottom ; but when there are many ovules there is usually some expansion of an ovule-bearing or seed-bearing surface ; as is seen in our Mandrake or Podophyllum, Fig. 326. 309. A Compound Hstfl is a combination of two, three, or a greater number of pistil-leaves or carpels in a circle, united into one body, at least by their ovaries. The annexed figures should make it clear. A series of Saxifrages might be selected the gyncecium of which would show every gradation between two simple pistils, or separate carpels, and their com- plete coalescence into one compound and two-celled ovary. Even when the constituent styles and stigmas are completely coalescent into one, the nature of the combination is usually revealed by some external lines or grooves, or (as in Fig. 328-330) by the internal partitions, or the number of the placentse. The simplest case of compound pistil is that 310. With two or more Cells and Axile Placentae, namely, with as many cells as there are carpels, that have united to compose the organ. FIG. 326. Simple pistil of Podophyllum, cut across, showing ovules borne on placenta. FIQ. 327.

Compound 3-carpellary pistil of Tradescantia or Spiderwort ; the three stigmas as well as styles and ovary completely coalescent into one. 108 COMPOUND PISTILS, [SECTION 10. Such a pistil is just what would be formed if the simple pistfls (two, three, or five in a circle, as the case may be), like those of a Pseony or Stonecrop (Fig. 224, 225), pressed together in the centre of the flower, were to cohere by their contiguous parts. In such a case the placentae are naturally axile, or all brought together in the axis or centre ; and the ovary has as many DISSEPIMENTS, or internal Partitions, as there are carpels in its composition. For these are the contiguous and coalesceut walls or sides of the component carpels. When such pistils ripen into pods, they often separate along these lines into their elementary carpels. 311. One-celled, with free Central Placenta. The commoner case is that of Purslane (Fig. 272) and of the Pink and Chickweed families (Fig. 331, 332). This is ex- plained by supposing that the partitions (such as those of Fig. 329) have early vanished or have been suppressed. In- deed, traces of them may often be detected in Pinks. On the other hand, it is equally supposable that in the Primula family the free central is de- rived from parietal placentation by the carpels bearing ovules only at base, and forming a consolidated common placenta in the axis. Mitella and Dionaea help out this conception. 312. One-celled, with Parietal Placentae. In this not uncommon case it is conceived that the two or three or more carpel-leaves of such a compound pistil coalesce by their adjacent edges, just as sepal-leaves do to form a gamo- sepalous calyx, or petals to form mm \*s. y*\ wST^M is shown in the diagram, Fig. 333, and in an actual cross-sec- tion, Fig. 334. Here each carpel is an open leaf, or with some introflexion, bearing ovules along its margins ; and each placenta consists of the con- PIG. 331, 832.

There is every grada- tion between this and the three-celled ovary with the placentae in the axis, even in the same genus, sometimes even in different stages in the same pistil (Fig. 335, 336). 2. GYMNOSPEEMOUS GYNffiCIUM. 318. The ordinary pistil has a closed ovary, and accordingly the pollen can act upon the contained ovules only indirectly, through the stigma. This is expressed in a term of Greek derivation, viz. : Angiospermous, meaning that the seeds are borne in a sac or closed vessel. The counterpart term is Gymnospermous, meaning naked-seeded. This kind of pistil, or gynoe- cium, the simplest of all, yet the most peculiar, characterizes the Pine family and its relatives. 314. While the ordinary simple pistil is conceived by the botanist to be a leaf rolled together into a closed pod (306), those of the Pine, Larch (Fig. 337), Cedar, and Arbor-Vita? (Fig. 338, 339) are open leaves, in the form of scales, each bearing two or more ovules on the inner face, next the base. At the time of blossoming, these pistil-leaves of the young cone diverge, and the pollen, so abundantly shed from the stam- inate blossoms, falls directly upon the exposed, ovules. Afterward the scales close over each' other until the seeds are ripe. Then they sepa- rate that the seeds may be shed. As the pollen acts directly on the ovules, such pistil (or organ acting as pistil) has no stigma. 315. In the Yew, and in Torreya and Gingko, the gynoecium is reduced to extremest simplicity, that is, to a naked ovule, without any visible carpel. 316. In Cycas the large naked ovules are borne on the margins or lobes of an obvious open leaf. All GYMNOSPEEMOUS plants have other peculiarities, also distinguishing them, as a class, from ANGIOSPEBMOUS plants. FIG. 337.

Ovule (from the Latin, meaning a little egg) is the technical of that which in the flower answers to and becomes the seed. 318. Ovules are naked in gymnospermous plants (as just described) ; in %U others they are enclosed in the ovary. They may be produced along the whole length of the cell or cells of the ovary, and then they are apt to be numerous ; or only from some part of it, generally the top or the bottom. In this case they are usually few or single (solitary, as in Fig. 341-343). They may be sessile, L e. without stalk, or they may be attached by a distinct stalk, the FUNICLE or FUNICULUS (Fig. 340). 319. Considered as to their position and direction in the ovary, they are Horizontal, when they are neither turned upward nor downward, as in Podophyllum (Fig. 326) ; Ascending^ when rising obliquely upwards, usually from the side of the cell, not from its very base, as in the But- tercup (Fig. 341), and the Purslane (Fig. 272); Erect, when rising upright from the very base of the cell, as in the Buck- wheat (Fig. 342); Pendulous, when hanging from the 841 342' 843 side or from near the top, as in the Flax (Fig. 270) ; and Suspended, when hanging perpendicularly from the very summit of the cell, as in the Anemone (Fig. 343). All these terms equally apply to seeds. 320. In structure an ovule is a pulpy mass of tissue, usually with one or two coats or coverings. The following parts are to be noted ; viz : KERNEL or NUCLEUS, the body of the ovule. In the Mistletoe and some related plants, there is only this nucleus, the coats being wanting. TEGUMENTS, or coats, sometimes only one, more commonly two. When two, one has been called PRIMINE, the other SECUNDINE. It will serve all purposes to call them simply outer and inner ovule-coats. ORIFICE, or FORAMEN, an opening through the coats at the organic apex of the ovule. In the seed it is Micropyle. CHALAZA, the place where the coats and the kernel of the ovule blend. HILUM, the place of junction of the ftmiculus with the body of the ovule. Fio. 340. A cluster of ovules, pendulous on their funicles. Fio. 841.

The ovules iu their growth develop in three or four different ways, and thereby, are distinguished into Ortkotropoits or Straight, those which develop without curving or turn- 347 ing, as in Fig. 344. The chalaza is at the insertion or base ; the foramen or orifice is at the apex. This is the simplest, but the least common kind of ovule. Campylotropous or Incurved, in which, by the greater growth of one side, the ovule curves into a kidney-shaped outline, so bringing the orifice down close to the base or chalaza; as in Fig. 345. Amphitropous or Half-Inverted, Fig. 346. Here the forming ovule, instead of curving perceptibly, keeps its axis nearly straight, and, as it grows, turns round upon its base so far as to become transverse to its funiculus, and adnate to its upper part for some distance. Therefore in this case the attachment of the funiculus or stalk is about the middle, the chal- aza is at one end, the orifice at the other. Anatropous or Inverted, as in Fig. 347, the com- monest kind, so called because in its growth it has as it were turned over upon its stalk, to which it has continued adnate. The organic base, or chalaza, thus becomes the apparent summit, and the FIG. 344. Orthotropous ovule of Buckwheat : e, hilum and chalaza; /, orifice. FIG. 345.

[SECTION 12. orifice is at the base, by the side of the hilum or place of attachment. The aduate portion of the fuuiculus, which appears as a ridge or cord extending from the hilum to the chalaza, and which distinguishes this kind of ovule, is called the RHAPHE. The amphitropous ovule (Fig. 346) has a short or incomplete rhaphe. 322. Fig, 348-352 show the stages through which an ovule becomes anatropous in the course of its growth. The annexed two figures are sec- tions of such an ovule at maturity ; and Fig. 355 is Fig. 353 enlarged, with the parts lettered. SECTION XII. MODIFICATIONS OF THE RECEPTACLE. 323. The Torus or Receptacle of the flower (237, Fig. 223) is the por- tion which belongs to the stem or axis. In all preceding illustrations it is small and short. But it sometimes lengthens, sometimes thickens or vari- ously enlarges, and takes on various forms. Some of these have received special names, very few of which are in common use. A lengthened por- tion of the receptacle is called A STIPE. This name, which means simply a trunk or stalk, is used in 8CT botany for various stalks, even for the leaf-stalk in Ferns. It is also applied to the stalk or petiole of a carpel, in the rare cases when there is any, as in FIG. 356. Longitudinal section of flower of Silene Pennsylvania, showing stipe between calyx and corolla. FIG. 357. Flower of a Cleome of the section Gynandropsis, showing broadened receptacle to bear petals, lengthened stipe below the stamens, and another between these and pistil. FIG. 358. Pistil of Geranium or Cranesbill. FIG. 359. The same, ripe, with the five carpels splitting away from the long beak (carpophore), and hanging from its top by their recurving styles. SECTION 12.] THE RECEPTACLE. 113 Goldthread. Then it is technically distinguished as a THECAPHORE. When there is a stalk, or lengthened internode of receptacle, directly under a compound pistil, as in Stanleya and some other Cruciferae, it is called a GYNOPHORE. When the stalk is developed below the stamens, as in most species of Silene (Tig. 356), it has been called an ANTHOPHORE or GONO- PHORE. In Fig. 357 the torus is dilated above the calyx where it bears the petals, then there is a long internode (gonophore) between it and the stamens ; then a shorter one (gynophore) between these and the pistil. 324. A Carpophore is a prolongation of receptacle or axis between the carpels and bearing them. Umbelliferous plants and Geranium (Fig. 358, 359) afford characteristic examples. 325. Flowers with very numerous simple pistils generally have the re- ceptacle enlarged so as to give them room ; sometimes becoming broad and tot, as in the Flowering Raspberry, sometimes elongated, as in the Black- berry, the Magnolia, etc. It is the receptacle in the Strawberry (Fig. 360), much enlarged and pulpy when ripe, which forms the eatable part qf the fruit, and bears the small seed-like pistils on its surface. In the Rose (Fig. 361), instead of being convex or conical, the receptacle is deeply concave, or urn-shaped. Indeed, a Rose-hip may be likened to a straw- berry turned inside out, like the finger of a glove reversed, and the whole covered by the adherent tube of the calyx. The calyx remains beneath in the strawberry. 326. In Nelumbium, of the Water-Lily family, the singu- lar and greatly enlarged receptacle is shaped like a top, and bears the small pistils immersed in separate cavities of its flat upper surface (Fig. 362). 327. A Disk is an enlarged low receptacle or an out- growth from it, hypogynous when underneath the pistil, as in Rue and the Orange (Fig. 363), and periffynom when aduate to calyx-tube (as in Buckthorn, Fig. 364, 365), and Cherry (Fig. 271), or FIG. 360. Longitudinal section of a young strawberry, enlarged. FIG. 361. Similar section of a young Rose-hip. FIG. 362. Enlarged and top-shaped receptacle of Nelumbium, at matnrity. Fio. 363.

A flattened hypogyuous disk, underlying the ovary or ovaries, and from which they fall away at maturity, is sometimes called GYNOBASE, as in the Rue family. In some Borragineous flowers, such as Houndstongue, the gynobase runs up in the centre between the carpels into a carpophore. The so-called epigynous disk (or STYLOPODIUM) crowning the summit of the ovary in flowers of Umbelliferse, etc., cannot be said to belong to the receptacle. SECTION XIIL FERTILIZATION. 328. The end of the flower is attained when the ovules become seeds. A flower remains for a certain time (longer or shorter according to the species) in anthesis, that is, in the proper state for the fulfilment of this end. During anthesis, the ovules have to be fertilized by the pollen ; or at Ibast some pollen has to reach the stigma, or in gymuospermy the ovule itself, and to set up the peculiar growth upon its moist and permeable tis- sue, which has for result the production of an embryo in the ovules. By this the ovules are said to be fertilized. The first step is pollination, or, so to say, the sowing of the proper pollen upon the stigma, where it is to germinate. 1. ADAPTATIONS FOR POLLINATION OF THE STIGMA. 329. These various and ever-interesting adaptations and processes are illustrated in the " Botanical Text Book, Structural Botany," chap. VI. sect, iv., also in a brief and simple way in " Botany for Young People, How Plants Behave." So mere outlines only are given here. 330. Sometimes the application of pollen to the stigma is left to chance, as in dioecious wind-fertilized flowers ; sometimes it is rendered very sure, as in flowers that are fertilized in the bud ; sometimes the pollen is prevented from reaching the stigma of the same flower, although placed very near to it, but then there are always arrangements for its transference to the stigma of some other blossom of the kind. It is among these last that the most exquisite adaptations are met with. 331. Accordingly, some flowers are particularly adapted to close or self- fertilization ; others to cross fertilization ; some for either, according to circumstances. FIG. 364. Flower of a Buckthorn showing a conspicuous perigynous disk. Flo. 365. Vertical section of same flowf . SECTION 13.J FERTILIZATION. 115 Close Fertilization occurs when the pollen reaches and acts upon a stigma of the very same flower (this is also called self-fertilization), or, less closely, upon other blossoms of the same clustei or the same individual plant. Cross Fertilization occurs when ovules are fertilized by pollen of other individuals of the same species. Hybridization occurs when ovules are fertilized by pollen of some other (necessarily some nearly related) species. 332. Close Fertilization would seem to be the natural result in ordi-' nary hermaphrodite flowers; but it is by no means so in all of them. More commonly the arrangements are such that it takes place only after some opportunity for cross fertilization has been afforded. But close fertiliza- tion is inevitable in what are called Cleistogamous Flowers, that is, in those which are fertilized in the flower-, bud, while still unopened. Most flowers of this kind, indeed, never open at all ; but the closed floral coverings are forced off by the growth of the precociously fertilized pistil. Common examples of this are found in the earlier blossoms of Specularia perfoliata, in the later ones of most Violets, es- pecially the stemless species, in our wild Jewel weeds or Impatiens, in the subterranean shoots of Amphicarpsea. Every plant which produces these cleistogamous or bud-fertilized flowers bears also more conspicuous and open flowers, usually of bright colors. The latter very commonly fail to set seed, but the former are prolific. 333. Cross Fertilization is naturally provided for in dioecious plants (249), is much favored in monoecious plants (249), and hardly less so in dichogamous and in heterogonous flowers (338). Cross fertilization depends upon the transportation of pollen ; and the two principal agents of convey- ance are winds and insects. Most flowers are in their whole structure adapted either to the one or to the other. 334. Wind-fertilizable or Anemophilous flowers are more commonly dioecious or monoecious, as in Pines and all coniferous trees, Oaks, and Birches, and Sedges; yet sometimes hermaphrodite, as in Plantains and most Grasses ; they produce a superabundance of very light pollen, adapted to be wind-borne; and they offer neither nectar to feed winged insects, nor fragrance nor bright colors to attract them. 335. Insect-fertilizable or Entomophilous flowers are those which are sought by insects, for pollen or for nectar, or for both. Through their visits pollen is conveyed from one flower and from one plant to another. Insects are attracted to such blossoms by their bright colors, or their fra- grance, or by the nectar (the material of honey) there provided for them. While supplying their own needs, they carry pollen from anthers to stigmas and from plant to plant, thus bringing about a certain amount of cross fer- tilization. Willows and some other dioecious flowers are so fertilized, chiefly by bees. But most insect-visited flowers have the stamens and pis- tils associated either in the same or in contiguous blossoms. Even when in the same blossom, anthers and stigmas are very commonly so pihia*-J 116 FERTILIZATION. [SECTION 13. that under insect- visitation, some pollen Is more likely to be deposited upon other than upon own stigmas, so giving a chance for cross as well as for close fertilization. On the other hand, numerous flowers, of very various kinds, have their parts so arranged that they must almost necessarily be cross- fertilized or be barren, and are therefore dependent upon the aid of insects. This aid is secured by different exquisite adaptations and contrivances, which would need a volume for full illustration. Indeed, there is a good number of volumes devoted to this subject. 1 336. Some of the adaptations which favor or ensure cross fertilization are peculiar to the particular kind of blossom. Orchids, Milkweeds, Kal- mia, Iris, and papilionaceous flowers each have their own special contriv- ances, quite different for each. 337. Irregular flowers (253) and especially irregular corollas are usu ally adaptations to insect-visitation. So are all Nectaries, whether hollow spurs, sacs, or other concavities in which nectar is secreted, and all nectar- iferons glands. 338. Moreover, there are two arrangements for cross fertilization com- mon to hermaphrodite flowers in various different families of plants, which have received special names, Dichogamy and Heterogony. 339. Dichogamy is the commoner case. Flowers are dichogamous when the anthers discharge their pollen either before or after the stigmas of that flower are in a condition to receive it. Such flowers are Proterandrous, when the anthers are earlier than the stigmas, as in Gen- tians, Campanula, Epilobium, etc. Proterogynous, when the stigmas are mature and moistened for the re- ception of pollen, before the anthers of that blossom are ready to supply it, and are withered before that pollen can be supplied. Plantains or Ribworts (mostly wind-fertilized) are strikingly proterogynous : so is Amor- pha, our Papaws, Scrophularia, and in a less degree the blossom of Pears, Hawthorns, and Horse-chestnut. 340. In Sabbatia, the large-flowered species of Epilobium, and strikingly hi Clerodendron, the dichogamy is supplemented and perfected by move- ments of the stamens and style, one or both, adjusted to make sure of cross fertilization. 341. Heterogony. This is the case in which hermaphrodite and fer- tile flowers of two sorts are produced on different individuals of the same species ; one sort having higher anthers and lower stigmas, the other hav- ing higher stigmas and lower anthers. Thus reciprocally disposed, a visit- ing insect carries pollen from the high anthers of the one to the high stigma of the other, and from the low anthers of the one to the low stigma of the other. These plants are practically as if dioecious, with the advantage thai 1 Beginning with one by C. C. Sprengel in 1793, and again in our day with Darwin, " On the Varions Contrivances by which Orchids are fertilized by Insects," nd in succeeding works. SECTION 14.] FRUIT. 117 both kinds are fruitful. Houstonia and Mitchella, or Partridge-berry, are excellent and familiar examples. These are cases of Heterogone Dimorphism, the relative lengths being only short and long reciprocally. Heterogone Trimorphism, in which there is a mid-length as well as a long and a short set of stamens and style ; occurs in Lythruin Salicaria and some species of Oxalis. 342. There must be some essential advantage in cross fertilization or cross breeding. Otherwise all these various, elaborate, and exquisitely adjusted adaptations would be aimless. Doubtless the advantage is the same as that which is realized in all the higher animals by the distinction of sexes. $ 2. ACTION OP POLLEN, AND FORMATION OF THE EMBRYO. 343. Pollen-growth. A grain of pollen may be justly likened to one of the simple bodies (spores') which answer for seeds in Cryptogamous plants. Like one of these, it is capable of germination. When deposited upon the moist surface of the stigma (or in some cases even when at a certain dis- tance) it grows from some point, its living inner coat breaking through the inert outer coat, and protruding in the form of a delicate tube. This as it lengthens penetrates the loose tissue of the stigma and of a loose conduct- ing tissue in the style, feeds upon the nourishing liquid matter there pro- vided, readies the cavity of the ovary, enters the orifice of an ovule, and attaches its extremity to a sac, or the lining of a definite cavity, in the ovule, called the Embryo-Sac. 344. Origination of the Embryo. A globule of living matter in the embryo-sac is formed, and is in some way placed in close proximity to the apex of the pollen tube ; it probably absorbs the contents of the latter ; it then sets up a special growth, and the Embryo (8-10) or rudimentary plautlet in the seed is the result. SECTION XIV. THE FEUIT. 345. Its Nature. The ovary matures into the Fruit. In the strictest sense the fruit is the seed-vessel, technically named the PERICARP. But practically it may include other parts organically connected with the peri- carp. Especially the calyx, or a part of it, is often incorporated with the ovary, so as to be undistinguishably a portion of the pericarp, and it even forms along with the receptacle the whole bulk of such edible fruits as apples and pears. The receptacle is an obvious part in blackberries, and is the whole edible portion in the strawberry. 346. Also a cluster of distinct carpels may, in ripening, be consolidated or compacted, so as practically to be taken for one fruit. Such are raspber- 118 FRUIT. [SECTION 14. ries, blackberries, the Magnolia fruit, etc. Moreover, the ripened product of many flowers may be compacted or grown together so as to form a single compound fruit. 347. Its kinds have therefore to be distinguished. Also various names of common use in descriptive botany have to be mentioned and defined. 348. In respect to composition, accordingly, fruits may be classified into Simple, those which result from the ripening of a single pistil, and con- sist only of the matured ovary, either by itself, as in a cherry, or with calyx-tube completely incorporated with it, as in a gooseberry or cranberry. Aggregate, when a cluster of carpels of the same flower are crowded into a mass ; as in raspberries and blackberries. Accessory or Anthocarpous, when the surroundings or supports of the pistil make up a part of the mass ; as does the loose calyx changed into a fleshy and berry-like envelope of our Wintergreen (Gaultheria, Fig. 366, 367) and Buffalo- berry, which are otherwise simple fruits. In an aggregate fruit such as the straw- berry the great mass is receptacle (Fig. 360, 368) ; and in the blackberry (Fig. 369) the juicy receptacle forms the central part of the savory mass. Multiple or Collective, when formed from several flowers consolidated into one mass, of which the common receptacle or axis of inflorescence, the floral envelopes, and even the bracts, etc., make a part. A mul- berry (Fig. 408, which superficially much resembles a blackberry) is of this multiple sort. A pine- apple is another ex- ample. 349. In respect to texture or consist- ence, fruit* may be distinguished into three kinds, viz. : Fleshy Fruits, those which are more or less soft and juicy throughout ; FIG. 366. Forming fruit (capsule) of Gaultheria, with calyx thickening around its base. 367. Section of same mature, the berry -like calyx nearly enclosing the capsule. FIG. 368.

In reference to the way of disseminating the contained seed, fruits are said to be IndeUscent when they do not open at maturity. Fleshy fruits and stone fruits are of course indehiscent. The seed becomes free only through decay or by being fed upon by animals. Those which escape digestion are thus disseminated by the latter. Of dry fruits many are indehiscent ; and these are variously arranged to be transported by animals. Some burst irregularly; many are Dehiscent, that is, they split open regularly along certain lines, and discharge the seeds. A dehiscent fruit almost always contains many or several seeds, or at least more than one seed. 871 373 878 374 351. The principal kinds of fruit which have received substantive names and are of common use in descriptive botany are the following. Of fleshy fruits the leading kind is 352. The Berry, such as the gooseoerry and currant, the blueberry and cranberry (Fig. 371), the tomato, and the grape. Here the whole flesh is soft throughout. The orange is a berry with a leathery rind. 353. The Pepo, or Gourd-fruit, is a hard-rinded berry, belonging to the Gourd family, such as the pumpkin, squash, cucumber, and melon, Fig. 372, 373. 354. The Pome is a name applied to the apple, pear (Fig. 374), and quince ; fleshy fruits, like a berry, but the principal thickness is calyx, only FIG. 371.

The fruit of the Hawthorn is a drupaceous pome, something be- tween pome and drupe. 355. Of fruits which are externally fleshy and internally hard the lead- ing kind is 356. The Drupe, or Stone-fruit; of which the cherry, plum, and peach (Tig. 375) are familiar examples. In this the outer part of the thickness of the pericarp be- comes fleshy, or softens like a berry, while the inner hardens, like a nut. From the way in which the pistil is constructed, it is evident that the fleshy part here answers to the lower, and the stone to the upper face of the component leaf. The layers or concentric portions of a drupe, or of any pericarp which is thus separable, are named, when thus distinguishable into three portions, Epicarp, the external layer, often the mere skin of the fruit, Mesocarp, the middle layer, which is commonly the fleshy part, and Endocarp, the innermost layer, the stone. But more commonly only two portions of a drupe are distinguished, and are named, the outer one Sarcocarp or Exocarp, for the flesh, the first name referring to the fleshy character, the second to its being an external layer; and Putamen or Endocarp, the Stone, within. 357. The typical or true drupe is of a single carpel. But, not to multiply technical names, this name is extended to all such fruits when fleshy without and stony within, although of compound pistil, even to those having several or separable stones, such as the fruit of Holly. These stones in such drupes, or drupaceous fruits, are called Pyretue, or Nucules, or simply Nutlets of the drupe. 358. Of Dry fruits, there is a greater diversity of kinds hav- ing distinct names. The indehis- cent sorts are commonly one- 359. The Akene or Ache- nium is a small, dry and indehis- cent one-seeded fruit, often so seed-like in appearance that it is 377 popularly taken for a naked seed. The fruit of the Butter cup or Crowfoot is a good example, Tig. 376, 377. Its nature, as a ripened pistil (in this Fio. 375. Longitudinal section of a peach, showing flesh, stone, and seed. Fio. 376.

It may retain the style and use it in various ways for dissemination (Fig. 378). . 360. The fruit of Composite (though not of a single carpel) is also an akene. In this case the pericarp is invested by an adherent calyx-tube ; the limb of which, when it has any, is called the PAPPUS. This name was first given to the down like that of the Thistle, but is applied to all forms under which the limb of the calyx of the " compound flower" appears. In Lettuce, Dandelion (Fig. 384), and the like, the achenium as it matures tapers upwards into a slendei beak, like a stalk to the pappus. 361. A Cremocarp (Fig. 385), a name given to the fruit of Umbelli ferae, consists as it were of a pair of akenes united com- pletely in the blossom, but splitting apart when ripe into the two closed carpels. Each of these is a Heri~ carp or Hemicarp, names seldom used. 362. A Utricle is the same as an akene, but with a thin and bladdery loose pericarp; like that of the Goosefoot or Pigweed (Fig. 386). When ripe it may burst open irregularly to discharge the seed ; or it may open by a circular line all round, the upper part fall- ing off like a lid ; as in the Amaranth (Tig. 387). 363. A Caryopsis, or Grain, is like an akene with the seed adhering to the thin pericarp throughout, so that fruit and seed are incorporated into one body ; as in wheat, Indian corn, and other kinds of gram,. 364. A Nut is a dry and indehiscent fruit, commonly one-celled and one. FIG. 379. Akene of Mayweed (uo pappus). 380. That of Succory (its pappus a shallow cup). 381.

[SECTION 14. seeded, with a hard, crustaceous, or bony wall, such as the cocoanut, hazel- nut, chestnut, and the acorn (Fig. 37, 388.) Here the involucre, in the form of a cup at the base, is called the CUPULE. In the Chestnut the cupule forms the bur; in the Hazel, a leafy husk. 365. A Samara, or Key-fruit, is either a nut or an akene, pr any other iudehiscent fruit, furnished with a wing, like that of Ash (Fig. 389), and Elm (Tig. 390). The Maple-fruit is a pair of keys (Fig. 391). 366. Dehiscent Fruits, or Pods, are of two classes, viz., those of a simple pistil or carpel, and those of a compound pistil. Two common sorts of the first are named as follows : 367. The Follicle is a fruit of a simple carpel, which dehisces down one side only, i. e. by the inner or ventral suture. The fruits of Marsh Marigold (Fig. 392), Pseony, Larkspur, and Milkweed are of this kind. 368. The Legume or true Pod, such as the peapod (Fig. 393), and the fruit of the Leguminous or Pulse family generally, is one which opens along the dorsal as well as the ventral suture. The two pieces into which it splits are called VALVES. A LOMENT is a legume which is constricted between the seeds, and at length breaks up crosswise into dis- tinct joints, as in Fig. 394. 369. The pods or dehiscent fruits belonging to a compound ovary have several technical names : but they all may be regarded as kinds of 370. The Capsule, the dry and dehiscent fruit of any compound pistil. The capsule may discharge its seeds through chinks or pores, as in the FIG. 388. Nut (acorn) of the Q0k, with its cup or cupule.

SECTION 14.] FRUIT. 123 Poppy, or burst irregularly iu some part, as in Lobelia and the Snapdragon ; but commonly it splits open (or is dehiscent) lengthwise into regular pieces, called VALVES. 371. Regular Dehiscence in a capsule takes place in two ways, which are best illustrated in pods of two or three cells. It is either Loculicidal, or, splitting directly into the loculi or cells, that is, down the back (or the dorsal suture) of each cell or carpel, as in Iris (Fig. 395) ; or A * Septicidal, that is, splitting through the partitions or septa, as in St. Jolm's-wort (Fig. 396), Rhododendron, etc. This divides the capsule into its compo- nent carpels, which then open by their ventral suture. 372. In loculicidal dehiscence the valves nat- urally bear the partitions on their middle ; in the septicidal, half the thickness of a partition is borne on the margin of each valve. See the annexed diagrams. A variation of either mode occurs when the valves break away from the partitions, these remaining attached in the axis of the fruit. This is called Septifrugal dehiscence. One form is seen in the Morning-Glory (Fig. 400). 373. The capsules of Rue, Spurge, and some others, are both loculi cidal and septicidal, and so split ^ into half-carpellary valves or pieces, f 374. The Silique (Fig. 401) is /\ the technical name of the peculiar I pod of the Mustard family ; which is two-celled by a false partition stretched across between two pa- rietal placentae. It generally opens by two valves from below up- /^ >>. ward, and the placentae with the / ^V partition are left behind when the / \. ^^ \ valves fall off. |^ 375 .

The Pyxis is a pod which opens by a circular horizontal line, the upper part forming a lid, as in Purslane (Fig. 404), the Plantain, Hen- bane, etc. In these the dehisceuce extends all round, or is cir- cumscissile. So it does in Amaranth (Fig. 387), forming a one- seeded utricular pyxis. In Jeffersouia, the line does not separate quite round, but leaves a portion for a hinge to the lid. 377. Of Multiple or Collective Fruits, which are properly masses of fruits aggregated into one body (as is seen in the Mulberry (Fig. 408), Pine- apple, etc.), there are two kinds with special names and of pe- culiar structure. 378. The Syconiumor Fig- 403 402 404 fruit (Fig. 405, 406) is a fleshy axis or summit of stem, hollowed out, and lined within by a multitude of minute flowers, the whole becoming pulpy, and in the common fig, luscious. 406 401 379. The Strobile or Cone (Fig. 411), is the peculiar multiple fruit of Pines, Cypresses, and the like : hence named Coniferee, viz. cone-bearing FIG. 401. Silique of a Cadamine or Spring Cress. FIG. 402.

Same, with fleshy calyx cat across. SECTION 15.] 125 plants. As already shown (313), these cones are open pistils, mostly in the form of flat scales, regularly overlying each other, and pressed together in a spike or head. Each scale bears one or two naked seeds on its inner face. When ripe and dry, the scales turn back or diverge, and in the Pine the seed peels off and falls, generally carrying with it a wing, a part of the lining of the scale, which facilitates the disper- sion of the seeds by the wind (Fig. 412, 413). In Arbor- Vitae, the scales of the small cone are few, and not very unlike the leaves. In Cy- press they are very thick at the top and narrow at the base, so as to make a peculiar sort of closed cone. In Juniper and Red Cedar, the few scales of the very small cone become fleshy, and ripen into a fruit which closely resembles a berry. SECTION XV. THE SEED. 380. Seeds are the final product of the flower, to which all its parts and offices are subservient. Like the ovule from which it originates, a seed consists of coats and kernel. 381. The Seed-coats are commonly two (320), the outer and the inner. Fig. 414 shows the two, in a seed cut through lengthwise. The outer coat is often hard or crustaceous, whence it is called the Testa, or shell of the seed ; the inner is almost al- ways thin and delicate. 382. The shape and the markings, so various in different seeds, depend mostly on the outer coat. Sometimes this fits the kernel closely ; sometimes it is expanded into a wing, as in the Trum- pet-Creeper (Fig. 415), and occasionally this wing is cut up into shreds or tufts, as in the Catalpa (Fig. 416) ; or instead of a wing it may bear a Coma, or tuft of long and soft hairs, as in the Milkweed or Silkweed (Fig. 417). The use of wings, or downy tufts is to render the seeds buoyant FIG. 411. Cone of a common Pitch Pine. 412. Inside view of a separated scale or open carpel ; one seed in place : 413, the other seed.

This is clear, not only from their evident adaptation to this purpose, but also from the fact that winged and tufted seeds are found only in fruits that split open at maturity, never in those jrifo that remain closed. The coat of some seeds is beset with /" v'.r\ long linirs or wool. Chiton, one of the most important vege- table products, since it forms the principal clothing of the larger part of the human race, consists of the long and woolly hairs which thickly cover the whole surface of the seed. There are also crests or other appendages of various sorts on certain seeds. A few seeds have an additional, but more or less incomplete covering, out- side of the real seed-coats called an 383. Aril, or Arillus. The loose and transparent bag which encloses the seed of the White Water-Lily (Fig. 418) is of this kind. So is the mace of the nutmeg ; and also the scarlet pulp around the seeds of the Waxwork (Celastrus) and Strawberry-bush (Euonymus). The aril is a growth from the ex- tremity of the seed-stalk, or from the placenta when there is no seed-stalk. 384. A short and thickish appendage at or close to the hilam in certain seeds is called a CARUNCLE or STROPHIOLE (Fig. 419). 385. The various terms which define the position or direc- tion of the ovule (erect, ascending, etc.) apply equally to the seed : so also the terms anatropous, orthotropous, campylotro- pous, etc., as already denned (320, 321), and such terms as HILUM, or Scar left where the seed-stalk or funiculus falls away, or where the seed was attached directly to the placenta when there is no seed-stalk. RHAPHE, the line or ridge which runs from the hilum to the chalaza in anatropous and amphitropous seeds. CHALAZA, the place where the seed-coats and the kernel or nucleus are organically connected, at the hilum in orthotropous and campylotropous seeds, at the extremity of the rhaphe or tip of the seed in other kinds. MICROPTLE, answering to the Foramen or orifice of the ovule. Compare the accompanying figures and those of the ovules, Fig. 341-355. Fio. 415. A winged seed of the Trumpet-Creeper. Flo. 416.

In many seeds the ker- nel is all Embryo , in others a large part of it is the ^/- bumen. For example, in Fig. 423, it is wholly embryo; in Fig. 422, all but the small 420 speck (g) is albumen. 387. The Albumen or Endosperm of the seed is sufficiently charac- terized and its office explained in Sect. III., 31-35. 388. The Embryo or Germ, which is the rudimentary plantlet and the final result of blossoming, and its development in germination have been extensively illustrated in Sections II. and III. Its essential parts are the Radicle and the Cotyledons. 389. Its Radicle or Caulicle (the former is the term long and gener- ally used in botanical descriptions, but the latter is the more correct one, for it is the initial stem, which merely gives origin to the root), as to its position in the seed, always points to and lies near the micropyle. In re- lation to the pericarp it is Superior, when it points to the apex of the fruit or cell, and Inferior, when it points to its base, or downward. 390. The Cotyledons have already been illustrated as re- spects their number, giving the important distinction of Dicoty- ledonous, Polycotyledonous and Monocotyledonous embryos (36-43), also as regards their thickness, whether foliaceous or fleshy ; and some of the very various shapes and adaptations to the seed have been figured. They may be straight, or folded, or rolled up. In the latter case the cotyledons may be rolled up as it were from one margin, as in Calycanthus (Fig. 424), or from apex to base in a flat spiral, or they may be both folded (plicate) and rolled up (convolute), as in Sugar Maple (Fig. 11.) In one very natural family, the Cruciferae, two different modes prevail in the way the two cotyledons are brought round against the radicle. In one series 425 426 they are FIG. 420. Seed of a Violet (anatropous) : o, hilum; b, rhaphe; c, chalaza. FIG. 421. Seed of a Larkspur (also anatropous); the parts lettered as in the last. FIG. 422.

Aecnmlent, that is, the edges of the flat cotyledons lie against the radicle, as in Fig. 425, 426. In another they are Incumbent, or with the plane of the cotyledons brought up in the opposite direction, so that the back of one of them lies against the radicle, as shown in Fig. 427, 428. 391. As to the situation of the embryo with respect to the albumen of the seed, when this is present in any quantity, the embryo may be Axile, that is occupying 427 428 the axis or centre, either for most of its length, as in Violet (Fig. 429), Barberry (Fig. 48), and Pine (Fig. 56) ; and in these it is straight. But it may be variously curved or coiled in the albumen, as in Helianthemum (Fig. 430), in a Potato-seed (Fig. 50), or Onion-seed (Fig. 60), and Linden (Fig. 414) ; or it may be coiled around the outside of the albumen, partly or into a circle, as in Chickweed (Fig. 431, 432) and in Mirabilis (Fig. 52). The latter mode prevails in Campylo- tropous seeds. In the cereal grains, such as Indian Corn (Fig. 67) and Rice, 430 ), and in all other Grasses, the embryo b straight and applied to the outside of the abundant albumen. 392. The matured seed, with embryo ready to germinate and reproduce the kind, completes the cycle of the vegetable life in a phanerogamous plant, the account of which began with the seed and seedling. SECTION XVI. VEGETABLE LIFE AND WOEK. 393. The following simple outlines of the anatomy and physiology ot plants (3) are added to the preceding structural part for the better prepar- ation of students in descriptive and systematic botany ; also to give to all learners some general idea of the life, growth, intimate structure, and action of the beings which compose so large a part of organic nature. Those who would extend and verify the facts and principles here outlined will use the Physiological Botany of the " Botanical Text Book," by Professor Goodale, or some similar book. FIG. 427.

Growth is the increase of a living thing in size and substance* It appears so natural that plants and animals should grow, that one rarely thinks of it as requiring explanation. It seems enough to say that a thing is so because it grew so. Growth from the seed, the germination and de- velopment of an embryo into a plantlet, and at length into a mature plant (as illustrated in Sections II. and III.), can be followed by ordinary obser- vation. But the embryo is already a miniature plantlet, sometimes with hardly any visible distinction of parts, but often one which has already made very considerable growth in the seed. To investigate the formation and growth of the embryo itself requires well-trained eyes and hands, and the expert use of a good compound microscope. So this is beyond the reach of a beginner. 395. Moreover, although observation may show that a seedling, weigh- ing only two or three grains, may double its bulk and weight every week of its early growth, and may in time produce a huge amount of vegetable matter, it is still to be asked what this vegetable matter is, where it came from, and by what means plants are able to increase and accumulate it, and build it up into the fabric of herbs and shrubs and lofty trees. 396. Protoplasm. All this fabric was built up under life, but only a small portion of it is at any one time alive. As growth proceeds, life is passed on from the old to the new parts, much as it has passed on from parent to offspring, from generation to generation in unbroken continuity. Protoplasm is the common name of that plant-stuff in which life essentially resides. All growth depends upon it; for it has the peculiar power of growing and multiplying and building up a living structure, the animal MO less than the vegetable structure, for it is essentially the same in both. Indeed, all the animal protoplasm comes primarily from the vegetable, which has the prerogative of producing it ; and the protoplasm of plants furnishes all that portion of the food of animals which forms their flesh and living fabric. 397- The very simplest plants (if such may specifically be called plants rather than animals, or one may say, the simplest living things) are mere particles, or pellets, or threads, or even' indefinite masses of protoplasm of vague form, which possess powers of motion or of changing their shape, of imbibing water, air, and even other matters, and of assimilating these into plant-stuff for their own growth and multiplication. Their growth is increase in substance by incorporation of that which they take in and assimilate. Their multiplication is by spontaneous division of their sub- stance or body into two or more, each capable of continuing the process. 398. The embryo of a phanerogamous plant at its beginning (344) is es- sentially such a globule of protoplasm, which soon constricts itself into two and more such globules, which hold together inseparably in a row ; then the last of the row divides without separation in the two other planes, tc 130 VEGETABLE LIFE AND WORK. [SECTION 16. form a compound mass, each grain or globule of which goes on to double itself as it grows; aud the definite shaping of this still increasing mass builds up the embryo into its form. 399. Cell-walls. While this growth was going on, each grain of the forming structure formed and clothed itself with a coat, tliiu and trans parent, of something different from protoplasm, something which hardly and only transiently, if at all, partakes of the life and action. The protoplasm forms the living organism ; the coat is a kind 433 f protective covering or shelL The protoplasm, like the flesh of animals which it gives rise to, is composed of four chemical elements: Carbon, Hydrogen, Oxygen, and Nitro- gen. The coating is of the nature of wood (is, indeed, that which makes wood), and has only the three elements, Car. bon, Hydrogen, and Oxygen, in its composition. 400. Although the forming structure of an embryo in the fertilized ovule is very minute and difficult to see, there are many simple plants of lowest grade, abounding in pools of water, which more readily show the earlier stages or sim- plest states of plant-growth. One of these, which is common in early spring, requires only moderate magnifying power to bring to view what is shown in Fig. 437. In a slimy mass which holds all loosely together, little spheres of green vegetable matter are seen, assembled in fours, and these fours themselves in clusters of fours. A transient inspection shows, what prolonged watching would confirm, that each sphere di- vides first in one plane, then in the other, to make four, soon acquiring the size of the original, and so on, producing successive groups of fours. These pellets each form on their surface a transparent wall, like that just des- cribed. The delicate wall is for some time capable of expan- sive growth, but is from the first much firmer than the protoplasm within; through it the latter imbibes sur- rounding moisture, which becomes a watery sap, occupy- ing vacuities in the protoplasmic mass which enlarge or run together as the periphery increases and distends. When full grown the protoplasm may become a mere lining to the wall, or some of it central, as a nucleus, this usually connected with the wall-lining by delicate threads of the same substance. So, when full grown, the wall with its lining a vesicle, containing liquid or some Flo. 433-436.

Bat the name was suggested by, and first used only for, cells in combination or built up into a fabric, much as a wall is built of bricks, that is, into a 401. Cellular Structure or Tissue. Suppose numerous cells like those of Fig. 437 to be heaped up like a pile of cannon-balls, and as they grew, to be compacted together while soft and yielding ; they would flatten where they touched, and each sphere, being touched by twelve surrounding ones would become twelve-sided. Fig. 438 would represent one of them. Suppose the contiguous faces to be united into one wall or partition be- tween adjacent cavities, and a cellular itructure would be formed, like that shown in Fig. 439. Hoots, stems, leaves, and the whole of phan- erogamous plants are a fabric of countless num- bers of sucli cells. No such exact regularity in size and shape is ever actually found ; but a nearly truthful magnified view of a small portion of a slice of the flower-stalk of a Calla Lily (Fig. 440) shows a fairly oorres ponding structure; except that, owing to the great air-spaces of the interior, the fabric may be likened rather to a stack of chimneys than to a solid fabric. In young and partly transparent parts one may discern the cel- lular structure by looking down directly on the surface, as of a form- ing root. (Fig. 82, 441, 442). 402. The substance of which cell-walls are mainly composed is called CELLULOSE. It is essentially the same in the stem of a delicate leaf or petal and in the wood of an Oak, except that in the latter the walls are Fio. 438.

The protoplasm of each living cell appears to be completely shut up and isolated in its shell of cellulose ; but microscopic investigation has brought to view, in many cases, minute threads of protoplasm which here and there traverse the cell-wall through minute pores, thus connecting the living portion of one cell with that of adjacent cells. (See Fig. 447, &c.) 403. The hairs of plants are cells formed on the surface ; either elongated single cells (like the root-hairs of Fig. 441, 442), or a row of shorter cells. Cotton fibres are long and simple cells grow- ing from the surface of the seed. 404. The size of the cells of which common plants are made up varies from about the thirtieth to the thou- sandth of an inch in diameter. An ordinary size of short or roundish cells is from -gfa to -fa of an inch ; so that there may generally be from 27 to 125 millions of cells in the compass of a cubic inch 1 405. Some parts are built up as a compact structure ; in others cells are arranged so as to build up regular air- channels, as in the stems of aquatic and other IjjIiHf: water-loving plants (Fig. 440), or to leave Wjj$ irregular spaces, as in the lower part of most ^M^ leaves, where the cells only here and there come into close contact (Fig. 443). 406. All such soft cellular tissue, like this of leaves, that of pith, and of the green bark, is called PARENCHYMA, while fibrous and woody parts are composed of PBOSEN- CHYMA, that is, of peculiarly transformed 407. Strengthening Cells. Common cellular tissue, which makes uu the whole structure of all very young plants, and the whole of Mosses and other vegetables of the lowest grade, even when full grown, is too tender or too brittle to give needful strength and toughness for plants which are to rise to any considerable height and support themselves. In these needful strength is imparted, and the conveyance of sap through the plant is facilitated, by the change, as they are formed, of some cells into thicker-walled and tougher tubes, and by the running together of some of Fia. 441.

Two sorts of such transformed cells go together, and essentially form the 408. Wood. This is found in all common herbs, as well as in shrubs and trees, but the former have much less of it in proportion to the softer cellular tissue. It is formed very early in the growth of the root, stem, and leaves, traces of it appearing in large embryos even while yet in the seed. Those cells that lengthen, and at the same time thicken their walls form the proper WOODY FIBRE or WOOD-CELLS ; those of larger size and thinner walls, which are thickened only in certain parts so as to have peculiar markings, and which often are seen to be made up of a row of cylindrical cells, with the partitions between absorbed or bro- ken away, are called DUCTS, or sometimes VESSELS. There are all gradations between wood-cells and ducts, and between both these and common cells. But in most plants the three kinds are fairly distinct. 409. The proper cellular tissue, or paren- chyma, is the ground-work of root, stem, and leaves ; this is traversed, chiefly lengthwise, by the strengthening and conducting tissue, wood-cells and duct-cells, in the form of bundles or threads, which, in the stems and stalks of herbs are fewer and comparatively scattered, but in shrubs and trees so numer- rous and crowded that in the stems and all permanent parts they make a solid mass of wood. They extend into and ramify in the leaves, spreading out in a horizontal plane, as the framework of ribs and veins, which supports the softer cellular portion or parenchyma, 410. Wood-Cells, or Woody Fibres, consist of tubes, commonly between one and two thousandths, but in Pine-wood sometimes two or three hundredths, of an inch in diameter.

Those of Buttonwood (Fig. 447) are larger, and are here highly magnified besides. The figures show the way wood-cells are commonly put together, namely, with their tapering ends overlapping each other, spliced together, as it were, thus giving more strength and toughness. In hard woods, such as Hickory and Oak, the walls of these tubes are very thick, as well as dense ; while in soft woods, such as White-Pine and Basswood, they are thinner. 411. Wood-cells in the bark are generally louger, finer, and tougher than those of the proper wood, and appear more like fibres. Tor example, Fig. 446 represents a cell of the wood of Basswood of average length, and Fig. 444 one (and part of another) of the fibrous bark, both drawn to the same scale. As these long cells form the principal part of fibrous bark, or bast, they are named Bast-cells or Bast-Jibres. These give the great tough- ness and flexibility to the inner bark of Basswood (i. e. Bast-wood) and of Leatherwood; and they furnish the invaluable fibres of flax and hemp; the proper wood of their stems being tender, brittle, and de- j stroyed by the processes which separate for use the tough and slender bast-cells. In Leather- wood (Dirca) the bast-cells are remarkably slender. A view of one, if magnified on the scale of Fig. 444, would be a foot and a half long. 412. The wood-cells of Pines, and more or less of all other Coniferous trees, have on two of their sides very peculiar disk-shaped markings (Fig. 448-450) by which that kind of wood is recognizable. 413. Ducts, also called VESSELS, are mostly larger than wood-cells : indeed, some of them, as in Red Oak, have calibre large enough to be discerned on a cross section by the naked eye. They make the visible porosity of such kinds of wood. This is particularly the case with Dotted ducts (Fig. 451, 452), the surface of which appears as if riddled with round or oval pores. Such ducts are commonly made up of a row of large cells more or less confluent into a tube.

Annular ducts (Fig. 457) are marked with cross lines or rings, which are thickened portions of the cell-wall. 457 Spiral ducts or vessels (Fig. 453-455) have thin walls, strengthened by a spiral fibre adherent within. This is as delicate and as strong as spider- web : when uncoiled by pulling apart, it tears up and annihilates the cell- wall. The uncoiled threads are seen by gently pulling apart many leaves, such as those of Amaryllis, or the stalk of a Strawberry leaflet. Laticiferous ducts, Vessels of the Latex, or Milk-vessels are peculiar branching tubes which hold latex or milky juice in certain plants. It is very difficult to see them, and more so to make out their nature. They are peculiar in branching and inosculating, so as to make a net-work of tubes, running in among the cellular tissue; and they are very small, except when gorged and old (Fig. 460, 461).

[SECTION 16. } 2. CELL-CONTENTS. 414. The living contents of young and active cells are mainly protoplasm with water or watery sap which this has imbibed. Old and effete cells are often empty of solid matter, containing only water with whatever may be dissolved in it, or air, according to the time and circumstances. All the various products which plants in general elaborate, or which particular plants specially elaborate, out of the common food which they derive from the soil and the air, are contained in the cells, and in the cells they are produced. 415. Sap is a general name for the principal liquid contents, Crude sap, for that which the plant takes in, Elaborated sap for what it has digested or assimilated. They must be undistinguishably mixed in the cells. 416. Among the solid matters into which cells convert some of their elaborated sap two are general and most important. These are Chlorophyll and Starch. 417. Chlorophyll (meaning leaf-green) is what gives the green color to herbage. It consists of soft grains of rather complex nature, partly wax- like, partly protoplasmic. These abound in the cells of all common leaves and the green rind of plants, wherever exposed to the light. The green nolor is seen through the transparent skin of the leaf and the walls of the containing cells. Chlorophyll is essential to ordinary assimilation in plants : . by its means, under the influence of sunlight, the plant converts crude sap into vegetable matter. 418. Tar the largest part of all vegetable matter produced is that which goes to build up the plant's fabric or cellular structure, either directly or indirectly. There is no one good name for this most important product of vegetation. In its final state of cell-walls, the permanent fabric of herb and shrub and tree, it is called Cellulose (408) : in its most soluble form it is Sugar of one or another kind ; in a less soluble form it is Dextrine, a kind of liquefied starch : in the form of solid grains stored up in the cells it is Starch. By a series of slight chemical changes (mainly a variation in the water entering into the composition), one of these forms is converted into another. 419. Starch (Farina or Fecula) is the form in which this common plant material is, as it were, laid by for future use. It consists of solid grains, somewhat different in form in different plants, in size varying from -g^-g- to 3-^jft, of an inch, partly translucent when wet, and of a pearly lustre. From the concentric lines, which commonly appear under the microscope, the grains seem to be made up of layer over layer. When loose they are com- monly oval, as in potato-starch (Fig. 462) : when much compacted the grains may become angular (Fig. 463). 420. The starch in a potato was produced in the foliage. In the soluble form of dextrine, or that of sugar, it was conveyed through the cells of the herbage and stalks to a subterranean shoot, and there stored up in the SECTION 16.) CELL-CONTENTS. 137 tuber. When the potato sprouts, the starch in the vicinity of developing buds or eyes is changed back again, first into mucilaginous dextrine, then into sugar, dissolved in the sap, and in this form it is made to flow to the growing parts, where it is laid down into cellulose or cell-wall. 421. Besides these cell-contents which are in obvious and essential rela- tion to nutrition, there are others the use of which is problematical. Of such the commonest are 422. Crystals. These when slender or needle-shaped are called RHAPHIDES. They are of inorganic matter, usually of oxalate or phosphate or sulphate of lime. Some, at least of the latter, may be direct crystalliza- tions of what is taken in dissolved in the water absorbed, but others must be the result of some elaboration in the plant. Some plants have hardly any ; others abound in them, especially in the foliage and bark. In Locust- bark almost every cell holds a crystal ; so that in a square inch not thicker than writing-paper there may be over a million and a half of them. When FIG. 462.

This is so nearly the same that an account of the internal structure of stems may serve for the root also. 424. At the beginning, either in the embryo or in an incipient shoot from a bud, the whole stem is of tender cellular tissue or parenchyma. But wood (consisting of wood-cells and ducts or vessels) begins to be formed in the earliest growth ; and is from the first arranged in two ways, making two general kinds of wood. The difference is obvious even in herbs, but is more conspicuous in the enduring stems of shrubs and 425. On one or the other of these two types the stems of all phanero- gamous plants are constructed. In one, the wood is made up of separate threads, scattered here and there throughout the whole diameter of the stem. In the other, the wood is all collected to form a layer (in a slice across the stem appearing as a ring) between a central cellular part which has none in it, the Pith, and an outer cellular part, the Bark. 426. An Asparagus-shoot and a Corn-stalk for herbs, and a rattan for a woody kind, represent the first kind. To it belong all plants with monocotyledonous em- bryo (40). A Bean-stalk and the stem of any com- mon shrub or tree rep- resent the second; and 471 472 to it belong all plants with dicotyledonous or polycotyledonous embryo. The first has been called, not very properly, Endogenous, which means in- side-growing ; the second, properly enough, Exogenous, or outside-growing. 427. Endogenous Stems, those of Monocotyls (40), attain their greatest size and most characteristic development "in Palms and Dragon- trees, therefore chiefly in warm climates, although the Palmetto and some Pro. 471.

SECTION 16.] ANATOMY OF STEMS. 139 Yuccas become trees along the southern borders of the United States. la such stems the woody bundles are more numerous and crowded toward the circumference, and so the harder wood is outside ; while in an exogenous stem the oldest and hardest wood is toward the centre. An endogenous stem has no clear distinction of pith, bark, and wood, concentrically ar- ranged, no silver grain, no annual layers, no bark that peels off clean from the wood. Yet old steins of Yuccas and the like, that continue to increase in diameter, do form a sort of layers and a kind of scaly bark when old. Yuccas show well the curving of the woody bundles (Fig. 471) which below taper out and are lost at the rind. 428. Exogenous Stems, those of Dicotyls (37), or of plants coming from dicotyledonous and also polycotyledouous embryos, have a structure which is familiar in the wood of our ordinary trees and shrubs. It is the same in an herbaceous shoot (such as a Flax-stem, Fig. 474) as in a Maple-stem of the first year's growth, except that the woody layer is com- monly thinner or perhaps reduced to a circle of bundles. It was so in the tree-stem at the beginning. The wood all forms in a cylinder, in cross section a ring around a cen- tral cellular part, dividing the cellular core within, the pith, from a celliv lar bark without. As the wood-bundles increase in number and in size, they press upon each other and become -wedge-shaped in the cross sec- tion ; and they continue to grow from the outside, next the bark, so that they become very thin wedges or plates. Between the plates or wedges are very thin plates (in cross section lines) of mnch compressed cellular tissue, which connect the pith with the bark. The plan of a one-year-old woody stem of this kind is exhibited in the figures, which are essentially diagrams. 429. Wlien such a stem grows on from year to year, it adds annually a Pio. 474.

[SECTION 16. layer of wood outside the preceding one, between that and the bark. This is exogenous growth, or outside-growing, as the name denotes. 430. Some new bark is formed every year, as well as new wood, the former inside, as the latter is outside of that of the year preceding. The ring or zone of tender forming tissue between the bark and the wood has been called the Cambium Layer. Cambium is an old name of the physiologists for nutritive juice. And this thin layer is so gorged with rich nutritive sap when spring growth is re- newed, that the bark then seems to be loose from the wood and a layer of viscid sap (or cambium) to be poured out between the two. But there is all the while a connection of the bark and the wood by delicate cells, rapidly mul- tiplying and growing. 431. The Bark of a year-old stem consists of three parts, more or less distinct, namely, beginning next the wood, 1. THE LIBER or FIBROUS BARK, the Inner Bark. This contains some wood-cells, or their equivalent, commonly in the form of bast or bast-cells (411, Fig. 444), such as those of Basswood or Linden, and among herbs those of flax and hemp, which are spun and woven or made into cordage. It also contains cells which are named *<?p*-cells, on account of numerous slits and pores in their walls, by which thf protoplasm of contiguous cells communicates. In woody stems, whenever a new layer ot wood is formed, some new liber or inner bark is also formed outride of it. 480 Fio. 478.

SECTION 16.] ANATOMY OF STEMS. 141 2. THE GREEN BARK or Middle Bark. This consists of cellular tissue only, and contains the same green matter (chlorophyll, 417) as the leaves. In woody stems, before the season's growth is completed, it becomes cov- ered by 3. THE CORKY LATEE or Outer Bark, the cells of which contain no chlorophyll, aud are of the nature of cork. Common cork is the thick corky layer of the bark of the Cork-Oak of Spain. It is this which gives to the stems or twigs of shrubs and trees the aspect and the color peculiar to each, light gray in the Ash, purple in the Red Maple, red in several Dogwoods, etc. 4. THE EPIDERMIS, or skin of the plant, consisting of a layer of thick- sided empty cells, which may be considered to be the outermost layer, or in most herbaceous stems the only layer, of cork-cells. 432. The green layer of bark seldom grows much after the first season. Sometimes the corky layer grows and forms new layers, inside of the old, for years, as in the Cork-Oak, the Sweet Gum-tree, and the White and the Paper Birch. But it all dies after a while ; and the continual enlargement of the wood within finally stretches it more than it can bear, and sooner or later cracks and rends it, while the weather acts powerfully upon its sur- face ; so the older bark perishes and falls away piecemeal year by year. 433. So on old trunks only the inner bark remains. This is renewed every year from within and so kept alive, while the older and outer layers die, are fissured and rent by the distending trunk, weathered and worn, and thrown off in fragments, in some trees slowly, so that the bark of old trunks may acquire great thickness ; in others, more rapidly. In Honey- suckles and Grape-Vines, the layers of liber loosen and die when only a year or two old. The annual layers of liber are sometimes as distinct as those of the wood, but often not so.

Section in the opposite direction, from bark (on the left) to beginning 9f pith (on the right), and a medullary ray extending from one to the other. 142 VEGETABLE LIFE AND WOR3, [SECTION 16. 434. The Wood of an exogenous trunk, having the old growths covered by the new, remains nearly unchanged in age, except from decay. Wherever there is an annual suspension and renewal of growth, as in temperate cli- mates, the annual growths are more or less distinctly marked, in the form of concentric rings on the cross section, so that the age of the tree may bt known by counting them. Over twelve hundred layers have been counted on the p*umps of Sequoias in California, and it is probable that some trees now living antedate the Christian era. 435. The reason why the annual growths are distinguishable is, that the wood formed at the beginning of the season is more or less different in the size or character of the cells from that of the close. In Oak, Chestnut, etc., the first wood of the season abounds in dotted ducts, the calibre of which is many times greater than that of the proper wood-cells. 436. Sap-wood, or Alburnum. This is the newer wood, living or recently alive, and taking part in the conveyance of sap. Sooner or later, each layer, as it becomes more and more deeply covered by the newer ones and farther from the region of growth, is converted into 437. Heart-wood, or Duramen. This is drier, harder, more solid, and much more durable as timber, than sap-wood. It is generally of a different color, and it exhibits in different species the hue peculiar to each, such as reddish in Red-Cedar, brown in Black-Walnut, black in Ebony, etc. The change of sap-wood into heart- wood results from the thickening of the walls of the wood-cells by the deposition of hard matter, lining the tubes and diminishing their calibre ; and by the deposition of a vegetable coloring- matter peculiar to each species. The heart-wood, being no longer a living part, may decay, and often does so, without the least injury to the tree, except by diminishing the strength of the trunk, and so rendering it more liable to be overthrown. 438. The Living Parts of a Tree, of the exogenous kind, are only these : first, the rootlets at one extremity ; second, the buds and leaves of the season at the other ; and third, e zone consisting of the newest wood and the newest bark, connecting the rootlets with the buds or leaves, how- ever widely separated these may be, in the tallest trees from two to foui h'm(*red feet apart. And these parts of the tree are all renewed every year. !No * :*><ler, therefore, that trees may live so long, since they annually re- prod tee everything that is essential to their life and growth, and since only a very small part of their bulk is alive at once. The tree survives, but nothing now living has been so long. In it, as elsewhere, life is a transi- tory tiling, ever abandoning the old, and renewed in the young, | 4. ANATOMY OF LEAVES. 439. The wood in leaves is the framework of ribs, veins, and veinlet* (125), serving not only to strengthen them, but also to bring in the sap, and to distribute it throughout nrery part. The cellular portion is the SECTION 16.] ANATOMY OF LEAVES. 143 green pulp, and is nearly the same as the green layer of the bark. So that the leaf may properly enough be regarded as a sort of expansion of the fibrous and green layers of the bark. It has no proper corky layer ; but the whole is covered by a transparent skin or epidermis, resembling that of the stem. 440. The cells of the leaf are of various forms, rarely so compact as to form a close cellular tissue, usually loosely arranged, at least in the lower part, so as to give copious intervening spaces or air passages, communi- cating throughout the whole interior (Fig. 443, 483). The green color is given by the chlorophyll (417), seen through the very transparent walls of the cells and through the translucent epidermis of the leaf. 441. In ordinary leaves, having an upper and under surface, the green cells form two distinct strata, of different arrangement. Those of the upper stratum are oblong or cylindrical, and stand endwise to the surface of the leaf, usually close together, leaving hardly any vacant spaces ; those of the lower are commonly irregular in shape, most of them with their longer diameter parallel to the face of the leaf, and are very loosely ar- ranged, leaving many and wide air-chambers. The green color of the lower is therefore diluted, and paler than that of the upper face of the leaf. The upper part of the leaf is so constructed as to bear the direct action of the sunshine ; the lower so as to afford freer circulation of air, and to facilitate transpiration. It communicates more directly than the upper with the external air by means of Stomates. 442. The Epidermis or skin of leaves and all young shoots is best seen in the foliage. It may readily be stripped off from the surface of a Lily-leaf, and still more so from more fleshy and soft leaves, such as those FIG. 483. Magnified section of a leaf of White Lily, to exhibit the cellular structure, both of upper and lower stratum, the air-passages of the lower, and the epidermis or skin, in section, also a little cf that of the Icwer face, with som of its stomate*. 144 VEGETABLE LIFE AND WORK. [SECTION 16. of Houseleek. The epidermis is usually composed of a single layer, occa- sionally of two or three layers, of empty cells, mostly of irregular outline. The sin- uous lines which traverse it, and may be dis- / " ^ ^ ) ( cerned under low powers of the microscope (Fig. 487), are the boundaries of the epidermal cells. 443. Breathing-pores, or Stomates, Stomata (singular, a Stoma, literally, a mouth) are openings through the epidermis into the air-chambers or intercellular passages, always between and guarded by a pair of thin- walled guardian cells. Although most abundant in leaves, especially on their lower face (that which is screened from direct sunlight), they are found on most other green parts. They establish a direct communication between the external air and that in the loose interior of the leaf. Their guardian cells or lips, which are soft and delicate, like those of the green pulp within, by their greater or less turgidity open or close the orifice as the moisture or dryness varies. 444. In the White Lily the stomata are so remarkably large that they may be seen by a simple microscope of moderate power, and may be dis- cerned even by a good hand lens. There are about 60,000 of them to the square inch of the epidermis of the lower face of this Lily-leaf, and only about 3000 to the same space on the upper face. It is computed that an average leaf of an Apple-tree has on its lower face about 100,000 of these mouths. 5. PLANT FOOD AND ASSIMILATION. 445. Only plants are capable of originating organizable matter, or the materials which compose the structure of vegetables and animals. The es- sential and peculiar work of plants is to take up portions of earth and air (water belonging to both) upon which animals cannot live at all, and to convert them into something organizable; that is, into something that, under life, may be built up into vegetable and animal structures. All the food of animals is produced by plants. Animals live upon vegetables, FIG. 484. Small portion of epidermis of the lower face of a White-Lily leaf, nth stomata. FIQ. 485.

The Food of plants, then, primarily, is earth and air. This is evident enough from the way in which they live. Many plants will flourish in pure sand or powdered chalk, or on the bare face of a rock or wall, watered merely with rain. And almost any plant may be made to grow from the seed in moist sand, and increase its weight many times, even if it will not come to perfection. Many naturally live suspended from the brandies of trees high in the air, and nourished by it alone, never hav- ing any connection with the soil ; and some which naturally grow on the ground, like the Live-forever of the gardens, when pulled up by the roots and hung in the air will often flourish the whole summer long. 447. It is true that fast-growing plants, or those which produce much vegetable matter in one season (especially in such concentrated form as to be useful as food for man or the higher animals) will come to maturity only in an enriched soil. But what is a rich soil ? One which contains decomposing vegetable matter, or some decomposing animal matter; that is, in either case, some decomposing organic matter formerly produced by plants. Aided by this, grain-bearing and other important vegetables will grow more rapidly and vigorously, and make a greater amount of nourish- ing matter, than they could if left to do the whole work at once from the beginning. So that in these cases also all the organic or organizable matter was made by plants, and made out of earth and air. Far the larger and most essential part was air and water. 448. Two kinds of material are taken in and used by plants ; of which the first, although more or less essential to perfect plant-growth, are in a certain sense subsidiary, if not accidental, viz. : Earthy constituents, those which are left in the form of ashes when a leaf or a stick of wood is burned in the open air. These consist of some potash (or soda in a marine plant), some silex (the same as flint), and a little lime, alumine, or magnesia, iron or manganese, sulphur, phosphorus, etc., some or all of these in variable and usually minute proportions. They are such materials as happen to be dissolved, in small quantity, in the water taken up by the roots ; and when that is consumed by the plant, or flies off pure (as it largely does) by exhalation, the earthy matter is left behind in the cells, just as it is left incrustiug the sides of a teakettle b which much hard water has been boiled. Naturally, therefore, there is more earthy matter (i. e. more ashes) in the leaves than in any other part (sometimes as much as seven per cent, when the wood contains only two per cent) ; because it is through the leaves that most of the water escapes from the plant. Some of this earthy matter incrusts the cell-walls, some goes to form crystals or rhaphides, which abound in many plants (422), some enters into certain special vegetable products, and some appears to be ne- cessary to the well-being of the higher orders of plants, although forming no necessary part of the proper vegetable structure. 10 U6 VEGETABLE LIFE AND WORK. [SECTION 16. The essential constituents of the organic fabric are those which are dissi- pated into air and vapor in complete burning. They make up from 88 to 99 per cent of the leaf or stem, and essentially the whole both of the cellu- lose of the walls and the protoplasm of the contents. Burning gives these materials of the plant's structure back to the air, mainly in the same condi- tion in which the plant took them, the same condition which is reached more slowly in natural decay. The chemical elements of the cell-walls (or cellulose, 402), as also of starch, sugar, and all that class of organizable cell-material, are carbon, hydrogen, and oxygen (399). The same, with nitrogen, are the constituents of protoplasm, or the truly vital part of vegetation. 449. These chemical elements out of which organic matters are com- posed are supplied to the plant by water, carbonic acid, and some combina- tions of nitrogen. Water^ far more largely than anything else, is imbibed by the roots ; also more or less by the foliage in the form of vapor. Water consists of oxygen and hydrogen; and cellulose or plant- wall, starch, sugar, etc., however different in their qualities, agree in containing these two elements in the same relative proportions as in water. Carbonic acid gas (Carbon dioxide) is one of the components of the atmos- phere, a small one, ordinarily only about 5-5^ ^ ^ s bulk, sufficient for the supply of vegetation, but not enough to be injurious to animals, as it would be if accumulated. Every current or breeze of air brings to the leaves expanded in it a succession of fresh atoms of carbonic acid, which it absorbs through its multitudinous breathing-pores. This gas is also taken up by water. So it is brought to the ground by rain, and is absorbed by the roots of plants, either as dissolved in the water they imbibe, or in the form of gas in the interstices of the soil. Manured ground, that is, soil containing decomposing vegetable or animal matters, is constantly giving out this gas into the interstices of the soil, whence the roots of the growing crop absorb it. Carbonic acid thus supplied, primarily from the air, is the source of the carbon which forms much the largest part of the substance of every plant. The proportion of carbon may be roughly estimated by charring some wood or foliage; that is, by heating it out of contact with the air, so as to decom- pose and drive off all the other constituents of the fabric, leaving the large bulk of charcoal or carbon behind. Nitrogen, the remaining plant-element, is a gas which makes up more than two thirds of the atmosphere, is brought into the foliage and also to the roots (being moderately soluble in water) in the same ways as is car- bonic acid. The nitrogen which, mixed with oxygen, a little carbonic acid, and vapor of water, constitutes the air we breathe, is the source of this fourth plant-element. But it is very doubtful if ordinary plants can use any nitrogen gas directly as food ; that is, if they can directly cause it to combine with the other elements so as to form protoplasm. But when com- bined with hydrogen ''forming ammonia), or wheu combined with oxygen SECTION 16.] PLANT FOOD AND ASSIMILATION. 147 (uitric acid and nitrates) plants appropriate it with avidity. And several natural processes are going on in which nitrogen of the air is so combined and supplied to the soil in forms directly available to the plant. The most efficient is nitrification, the formation of nitre (nitrate of potash) in the soil, especially in all fertile soils, through the action of a bacterial ferment. 450. Assimilation in plants is the conversion of these inorganic sub- stances essentially, water, carbonic acid, and some form of combined or combinable nitrogen into vegetable matter. This most dilute food the living plant concentrates and assimilates to itself. Only plants are capable of converting these mineral into organizable matters ; and this all-important work is done by them (so far as all ordinary vegetation is concerned) only 451. Under the light of the sun, acting upon green parts or foliage, that is, upon the chlorophyll, or upon what answers to chlorophyll, which these parts contain. The sun in some way supplies a power which enables the living plant to originate these peculiar chemical combinations, to organ- ize matter into forms which are alone capable of being endowed with life. The proof of this proposition is simple ; and it shows at the same time, in the simplest way, what a plant does with the water and carbonic acid it consumes. Namely, 1st, it is only in sunshine or bright daylight that the green parts of plants give out oxygen gas, then they regularly do so ; and 3d, the giving out of this oxygen gas is required to render the chemical composition of water and carbonic acid the same as that of cellulose, that is, of the plant's permanent fabric. This shows why plants spread out so large a surface of foliage. Leaves are so many workshops, full of ma- chinery worked by sun-power. The emission of oxygen gas from any sun-lit foliage is seen by placing some of this under water, or by using an aquatic plant, by collecting the air bubbles which rise, and by noting that a taper burns brighter in this air. Or a leafy plant in a glass globe may be supplied with a certain small percentage of carbonic acid gas, and after proper exposure to sunshine, the air on being tested will be found to con- tain less carbonic acid and just so much the more oxygen gas. 452. Now if the plant is making cellulose or any equivalent substance, that is, is making the very materials of its fabric and growth, as must generally be the case, all this oxygen gas given off by the leaves comes from the decomposition of carbonic acid taken in by the plant. For cellu- lose, and also starch, dextrine, sugar, and the like are composed of carbon along with oxygen and hydrogen in just the proportions to form water. And the carbonic acid and water taken in, less the oxygen which the carbon brought with it as carbonic acid, and which is given off from the foliage in sunshine, just represents the manufactured article, cellulose. 453. It comes to the same if the first product of assimilation is sugar, or dextrine which is a sort of soluble starch, or starch itself. And in the plant all these forms are readily changed into one another. In the tiny seedling, as fast as this assimilated matter is formed it is used in growth, that is, in the formation of cell-walls. After a time some or much 01 148 VEGETABLE LIFE AND WORK. [SECTION 16. the product may be accumulated in store for future growth, as in the root of the turnip, or the tuber of the potato, or the seed of corn or pulse, rhia store is mainly in the form of starch. When growth begins anew, this starch is turned into dextrine or into sugar, in liquid form, and used to nourish and build up the germinating embryo or the new shoot, where it is at length converted into cellulose and used to build up plant-structure. 454> But that which builds plant-fabric is not the cellular structure itself; the work is doue by the living protoplasm which dwells within the walls. This also has to take and to assimilate its proper food, for its own maintenance and growth. Protoplasm assimilates, along with the other three elements, the nitrogen of the plant's food. This comes primarily from the vast stock in the atmosphere, but mainly through the earth, where it is accumulated through various processes in a fertile soil, mainly, so far as concerns crops, from the decomposition of former vegetables and animals. This protoplasm, which is formed at the same time as the simpler cellulose, is essentially the same as the flesh of animals, and the source of it. It is the common basis of vegetable and of animal life. 455. So plant-assimilation produce* all the food and fabric of animals, Starch, sugar, the oils (which are, as it were, these farinaceous matters more deoxidated), chlorophyll, and the like, and even cellulose itself, form the food of herbivorous animals and much of the food of man. When digested they enter into the blood, undergo various transformations, and are at length decomposed into carbonic acid and water, and exhaled from the lungs in respiration, in other words, are given back to the air by the ani- mal as the very same materials which the plant took from the air as its food, are given back to the air in the same form that they would have taken if the vegetable matter had been left to decay where it grew, or if it had been set on fire and burned ; and with the same result, too, as to the heat, the heat in this case producing and maintaining the proper temperature of the animal. 456. The protoplasm and other products containing nitrogen (gluten, legumine, etc.), and which are most accumulated in grains and seeds (for the nourishment of their embryos when they germinate), compose the most nutritious vegetable food consumed by animals; they form their proper flesh and sinews, while the earthy constituents of the plant form the earthy matter of the bones, etc. At length decomposed, in the secretions and excretions, these nitrogenous constituents are through successive changes finally resolved into mineral matter, into carbonic acid, water, and ammonia or some nitrates, into exactly or essentially the same materials which the plants took up and assimilated. Animals depend upon vegetables abso- lutely and directly for their subsistence ; also indirectly, because 457. Plants purify the air for animals. In the very process by which they create food they take from the air carbonic acid gas, injurious to animal res- piration, which is continually poured into it by the breathing of all animals, by all decay, by the burning of fuel aud all other ordinary combustion; and SECTION 16.] MOVEMENTS. 149 they restore an equal bulk of life-sustaining oxygen needful for the respiration of animals, needful, also, in a certain measure, for plants in any work they do. for in plants, as well as in animals, work is done at a certain coat 6. PLANT WORK AND MOVEMENT. 458. As the organic basis and truly living material of plants is identical with that of animals, so is the life at bottom essentially the same ; but in animals something is added at every rise from the lowest to highest organ- isms. Action and work in living beings require movement. 459. Living things move; those not living are only moved. Plants move as truly as do animals. The latter, nourished as they are upon or- ganized food, which has been prepared for them by plants, and is found only here and there, must needs have the power of going after it, of collect- ing it, or at least of taking it in ; which requires them to make spontaneous movements. But ordinary plants, with their wide-spread surface, always hi contact with the earth and air on which they feed, the latter every- where the same, and the former very much so, might be thought to have no need of movement. Ordinary plants, indeed, have no locomotion ; some float, but most are rooted to the spot where they grew. Yet probably ah 1 of them execute various movements which must be as truly self-caused as are those of the lower grades of animals, movements which are over- looked only because too slow to be directly observed. Nevertheless, the motion of the hour-hand and of the minute-hand of a watch is not less real than that of the second-hand. 460. Locomotion. Moreover, many microscopic plants living in water are seen to move freely, if not briskly, under the microscope ; and so like- wise do more conspicuous aquatic plants in their embryo- like or seedling state. Even at maturity, species of Oscillaria (such as hi Fig. 488, minute worm-shaped plants of fresh waters, taking this name from their oscillating motions) freely execute three different kinds of movement, the very delicate investing coat of cellulose not impeding the action of the living protoplasm within. Even when this coat is firmer and hardened with a siliceous deposit, such crescent-shaped or boat-shaped one-celled plants as Closterium or Navicvla are able in some way to move along from place to place in the water. 461. Movements in Cells, or Cell-circulation, sometimes called Cy* closis, has been detected in so many plants, especially in comparatively FIG. 488. Two individuals of an Oscillaria, magnified. 150 VEGETABLE LIFE AND WORK. [SECTION 16. transparent aquatic plants and in hairs on the surface of land plants (where it is easiest to observe), that it may be inferred to take place in all cells during the most active part of their life. This motion is commonly a treaming movement of threads of protoplasm, carrying '^ A tr~=si along solid granules by which the action may be ob- served and the rate measured, or in some cases it is a rotation of the whole protoplasmic contents of the cell. A comparatively low magnifying power will show it in the cells of Nitella and Chara (which are cryptogamous plants) ; and under a moderate power it is well seen in the Tape Grass of fresh water, Vallisneria, and in Naias flexilis (Fig. 489). Minute particles and larger green- ish globules are seen to be carried along, as if in a cur- rent, around the cell, passing up one side, across the end, down the other and across the bottom, completing the circuit sometimes within a minute or less when well warmed. To see it well in the cell, which like a string of beads form the hairs on the stamens of Spiderwort, a high magnifying power is needed. 462. Transference of Liquid from Cell to Cell, and so from place to place in the plant, the absorption of water by the rootlets, and the exhalation of the greater part of it from the foliage, these and similar operations are governed by the physical laws which regulate the diffusion of fluids, but are controlled by the action of living protoplasm. Equally under vital control are the various chemical transformations which attend assimilation and growth, and which involve not only molecular movements but conveyance. Growth itself, which is the formation and shaping of new parts, implies the direction of internal activities to definite ends. 463. Movements of Organs. The living protoplasm, in all but the lowest grade of plants, is enclosed and to common appearance isolated in separate cells, the walls of which can only in their earliest state be said to be alive. Still plants are able to cause the protoplasm of adjacent cells to act in concert, and by their combined action to effect movements in roots, stems, or leaves, some of them very slow and gradual, some manifest and striking. Such movements are brought about through individually minute changes in the form or tension in the protoplasm of the innumera- ble cells which make up the structure of the organ. Some of the slower movements are effected during growth, and may be explained by inequality of growth on the two sides of the bending organ. But the more rapid changes of position, and some of the slow ones, cannot be so explained. FIG. 489. A few cells of a leaf of Naias flexilis, highly magnified: the arrows Indicate the courses of the circulating currents- SECTION 16.J MOVEMENTS. 151 464. Boot-movements, In its growth a root turns or bends away from the light and toward the centre of the earth, so that in lengthening it buries itself in the soil where it is to live and act. Every one must have observed this in the germination of seeds. Careful observations have shown that the tip of a growing root also makes little sweeps or short 'movements from side to side. By this means it more readily insinuates itself into yielding portions of the soil. The root-tips will also turn toward moisture, and so secure the most favorable positions in the soil. 465. Stem-movements. The root end of the caulicle or first joint ot stem (that below the cotyledons) acts like the root, in turning downward in germination (making a complete bend to do so if it happens to point upward as the seed lies in the ground), while the other end turns or points skyward. These opposite positions are taken in complete dark- ness as readily as in the light, in dryness as much as in moisture : there fore, so far as these movements are physical, the two portions of the same internode appear to be oppositely aifected by gravitation or other in- fluences. 466. Rising into the air, the stem and green shoots generally, while young and pliable, bend or direct themselves toward the light, or toward the stronger light when unequally illuminated ; while roots turn toward the darkness. 467. Many growing stems have also a movement of Nutation, that is, of nodding successively in different directions. This is brought about by a temporary increase of turgidity of the cells along one side, thus bowing the stem over to the opposite side; and this line of turgescence travels round the shoot continually, from right to left or from left to right accord- ing to the species : thus the shoot bends to all points of the compass in succession. Commonly this nutation is slight or hardly observable. It is most marked in 468. Twining Stems (Fig. 90). The growing upper end of such stems, as is familiar in the Hop, Pole Beans, and Morning-Glory, turns over in an inclined or horizontal direction, thus stretching out to reach a neighboring support, and by the continual change in the direction of the nodding, sweeps the whole circle, the sweeps being the longer as the stem lengthens. When it strikes against a support, such as a stem or branch of a neighboring plant, the motion is arrested at the contact, but continues at the growing apex beyond, and this apex is thus made to wind spirally around the supporting body. 469. Leaf-movements are all but universal. The presentation by most leaves of their upper surface to the light, from whatever direction that may come, is an instance ; for when turned upside down they twist or bend round on the stalk to recover this normal position. Leaves, and the leaflets of compound leaves, change this position at nightfall, or when the light is withdrawn ; they then take what is called their sleeping posture, resuming the diurnal position when daylight returns. This is very striking 152 VEGETABLE LIFE AND WORK. [SECTION 16. in Locust-trees, in the Sensitive Plant (Fig. 490), and in Woodsorrel. Young seedlings droop or close their leaves at night in plants which are not thus affected in the adult foliage. All this is thought to be a protec- tion against the cold by nocturnal radiation. 470. Various plants climb by a coiling movement of their leaves or their leaf-stalks. Familiar examples are seen in Clematis, Maurandia, Tropseo- lum, and in a Solanum which is much cultivated in greenhouses (Fig. 172). In the latter, and in other woody plants which climb in this way, the petioles thicken and harden after they have grasped their support, thus securing a very firm hold. 471. Tendril movements. Tendrils are either leaves or stems (98, 168), specially developed for climbing purposes. Cobeea is a good exam. pie of partial transformation ; some of the leaflets are normal, some of the same leaf are little tendrils, and some intermediate in character. The Passion-flowers give good examples of simple stem-tendrils (Fig. 92) ; Grape- Vines, of branched ones. Most tendrils make revolving sweeps, like those of twining stems. Those of some Passion-flowers, in sultry weather, are apt to move fast enough for the movement actually to be seen for a part of the circuit, as plainly as that of the second-hand of a watch. Two herbaceous species, Passiflora gracilis and P. sicyoides (the first an annual, the second a strong-rooted perennial of the easiest cultivation), are admirable for illustration both of revolving movements and of sensitive coiling. 472. Movements under Irritatioa The most familiar case is that of the Sensitive Plant (Fig. 490). The leaves suddenly take their nocturnal position when roughly touched or when shocked by a jar. The leaflets close in pairs, the four outspread par- tial petioles come closer together, and the common petiole is depressed. The seat of the move- ments is at the base of the leaf-stalk and stalk- lets. Schrankia, a near relative of the Sensitive Plant, acts in the same way, but is slower. These are not anoma- lous actions, but only extreme manifestations of a faculty more or less common in foliage. In Locust and Honey-Locusts for example, repeated jars will slowly pro* dnce similar effects. FIG. 490. Piece of stem of Sensitive Plant (Mimosa pudica), with two leaves, the lower open, the upper in the closed state. SECTION 16.] MOVEMENTS. 153 473. Leaf -stalks and tendrils are adapted to their uses in climbing by a similar sensitiveness. The coiling of the leaf-stalk is in response to a kind of irritation produced by contact with the supporting body. This may be shown by gentle rubbing or prolonged pressure upon the upper face of the leaf-stalk, which is soon followed by a curvature. Ten- drils are still more sensitive to contact or light friction. This causes the free end of the tendril to coil round the support, and the sensitiveness, propagated downward along the tendril, causes that side of it to become less turgesceut or the opposite side more so, thus throwing the tendril into coils. This shortening draws the plant up to the support. Tendrils which have not laid hold will at length commonly coil spontaneously, in a simple coil, from the free apex downward. In Sicyos, Echinocystis, and the above mentioned Passion-flowers (471), the tendril is so sensitive, under a high summer temperature, that it will curve and coil prompt- ly after one or two light sttokes by the hand. 474. Among spontaneous move- ments the most singular are those of Desmodium gyrans of India, sometimes called Telegraph-plant, which is cultivated on account of this action. Of its three leaflets, the larger (terminal) one moves only by drooping at nightfall and rising with the dawn. But its two small lateral leaflets, when in a congenial high temperature, by day and by night move upward and downward in a succession of jerks, stopping occasionally, as if to re- cover from exhaustion. In most plant-movements some obviously useful purpose is subserved : this of Desmodium gyrans is a riddle. 475. Movements in Flowers are very various. The most remarkable are in some way connected with fertilization (Sect. XIII.). Some occur under irritation : the stamens of Barberry start forward when touched at the base inside : those of many polyandrous flowers (of Sparmannia very strikingly) spread outwardly when lightly brushed : the two lips or lobes FIG. 491. Portion of stem and leaves of Telegraph-plant (Desmodium gyrans), almost of natural size. 154 VEGETABLE LIFE AND WORK. [SECTION 16. of the stigma in Mimulus close after a touch. Some are automatic and are connected with dichogamy (339) : the style of Sabbatia and of large- flowered species of Epilobium bends over strongly to one side or turns down- ward when the blossom opens, but slowly erects itself a day or two later. 476. Extraordinary Movements connected with Capture of In- sects. The most striking cases are those of Drosera and Dionaea ; for an account of which see "How Plants Behave," and Goodale's " Physiological Botany." 477. The upper face of the leaves of the common species of Drosera, or Sundew, is beset with stout bristles, having a glandular tip. This tip secretes a drop of a clear but very viscid liquid, which glistens like a dew- drop in the sun ; whence the popular name. When a fly or other small insect, attracted by the liquid, alights upon the leaf, the viscid drops are so tenacious that they hold it fast. In struggling it only becomes more com- pletely entangled. Now the neighboring bris- tles, which have not been touched, slowly bend inward from all sides toward the captured in- sect, and bring their sticky apex against its body, thus increasing the number of bonds. Moreover, the blade of the leaf commonly aids in the capture by becoming concave, its sides or edges turning inward, which brings still more of the gland-tipped bristles into contact with the captive's body. The insect per- ishes ; the clear liquid disappears, apparently by absorption into the tissue of the leaf. It is thought that the absorbed secretion takes with it some of the juices of the insect or the products of its decompo- sition. 478. Dionsea muscipula, the most remarkable vegetable fly-trap (Fig. 176, 492), is related to the Sundews, and has a more special and active apparatus for fly- catching, formed of the summit of the leaf. The two halves of this rounded body move as if they were hinged upon the midrib; their edges are fringed with spiny but not glandular bristles, which interlock when the organ closes. Upon the face are two or three short and delicate bristles, whicli are sensitive. They do not themselves move when touched, but they propagate the sensitiveness to the organ itself, causing it to close with a quick movement. In a fresh Fio. 492. Plant of Dionaea muscipula, or Venus's Fly-trap, reduced in size. SECTION 16.] TRANSFORMING MATERIAL AND ENERGY. 155 and vigorous leaf, under a high summer temperature, and when the trap lies widely opeu, a touch of any one of the minute bristles on the face, by the finger or any extraneous body, springs the trap (so to say), and it closes suddenly ; but after an hour or so it opens again. When a fly or other small insect alights on the trap, it closes in the same manner, and so quickly that the intercrossing marginal bristles obstruct the egress of the insect, unless it be a small one and not worth taking. Afterwards and more slowly it completely closes, and presses down upon the prey ; then some hidden glands pour out a glairy liquid, which dissolves out the juices of the insect's body ; next all is re-absorbed into the plant, and the trap opens to repeat the operation. But the same leaf perhaps never captures more than two or three insects. It ages instead, becomes more rigid and motionless, or decays away. 479. That some few plants should thus take animal food will appear less surprising when it is considered that hosts of plants of the lower grade, known as Fungi, moulds, rusts, ferments, Bacteria, etc., live upon animal or other organized matter, either decaying or living. That plants should execute movements in order to accomplish the ends of their existence is less surprising now when it is known that the living substance of plants and animals is essentially the same ; that the beings of both kingdoms par- take of a common life, to which, as they rise in the scale, other and higher endowments are successively superadded. 480. Work uses up material and energy in plants as well as in ani- mals. The latter live and work by the consumption and decomposition of that which plants have assimilated into organizable matter through an energy derived from the sun, and which is, so to say, stored up hi the as- similated products. In every internal action, as well as in every movement and exertion, some portion of this assimilated matter is transformed and of its stored energy expended. The steam-engine is an organism for con- verting the sun's radiant energy, stored up by plants in the fuel, into me- chanical work. An animal is an engine fed by vegetable fuel in the same or other forms, from the same source, by the decomposition of which it also does mechanical work. The plant is the producer of food and accumu- lator of solar energy or force. But the plant, like the animal, is a con- sumer whenever and by so much as it does any work except its great work of assimilation. Every internal change and movement, every transforma- tion, such as that of starch into sugar and of sugar into cell-walls, as well as every movement of parts which becomes externally visible, is done at the expense of a certain amount of its assimilated matter and of its stored energy ; that is, by the decomposition or combustion of sugar or some such product into carbonic acid and water, which is given back to the air, just as in the animal it is given back to the air in respiration. So the respira tion of plants is as real and as essential as that of animals. But what plants consume or decompose in their life and action is of insignificant amount ia comparison with what they compose. 156 CRYPTOGAMOUS OE FLOWEKLESS PLANTS. [SECTION 17. SECTIO* XVH. CBYPTOGAMOU8 OB FLOWERLESS PLANTS. 481. Even the beginner in botany should have some general idea of what cryptogamoua plants are, and what are the obvious distinctions of the principal families. Although the lower grades are difficult, and need special books and good microscopes for their study, the higher orders, such as Ferns, may be determined almost as readily as phanerogamous plants. 482. Linnaeus gave to this lower grade of plants the name of Crypto- gamia, thereby indicating that their organs answering to stamens and pistils, if they had any, were recondite and unknown. There is no valid reason why this long-familiar name should not be kept up, along with the counterpart one of Phanerogamia (6), although organs analogous to stamens and pistil, or rather to pollen and ovule, have been discovered in all the higher and most of the lower grades of this series of plants. So also the English synonymous name of Flowerless Plants is both good and con- venient : for they have not flowers in the proper sense. The essentials of flowers are stamens and pistils, giving rise to seeds, and the essential of a seed is an embryo (8). Cryptogamous or Flowerless plants are propagated by SPORES; and a spore b not an embryo-plantlet, but mostly a single plant-cell (399). 483. Vascular Cryptogams, which compose the higher orders of this series of plants, have stems and (usually) leaves, constructed upon the general plan of ordinary plants ; that is, they have wood (wood-cells and vessels, 408) in the stem and leaves, in the latter as a frame work of veins. But the lower grades, having only the more elementary cellular structure, are called Cellular Cryptogams. Far the krger number of the former are Ferns : wherefore that class has been called 484. Pteridophyta, Pteridophytes in English form, meaning Fern- plants, that is, Ferns and their relatives. They are mainly Horsetails, Ferns, Club-Mosses, and various aquatics which have been called Hi/drop- terides, i. e. Water-Ferns. 485. HorsetaUs, Equisetacea, is the name of a family which consists only (among now-living plants) of Equisetum, the botanical name of Horse- tail and Scouring Rush. They have hollow stems, with partitions at the nodes; the leaves consist only of a whorl of scales at each node, these coalescent into a sheath : from the axils of .these leaf-scales, in many species, branches grow out, which are similar to the stem but on a much smaller scale, close-jointed, and with the tips of the leaves more apparent. At the apex of the stem appears the fructification, as it is called for lack of a better term, in the form of a short spike or head. This consists of a good num ber of stalked shields, bearing on their inner or under face several wedge. shaped spore-cases. The spore-cases when they ripen open down the innef SECTION 17.] PTERIDOPHYTES. 157 side and discharge a great number of green spores of a size large enough to he well seen by a hand-gkss. The spores are aided in their discharge and dissemination by four club-shaped threads attached to one part of them These are hygrometric : when moist they are rolled up over the spore ; when dry they straighten, and exhibit lively movements, closing over the spore when breathed upon, and unrolling promptly a moment after as they dry. (See Fig. 493-498.; 486. Ferns, or Filices, a most attractive family of plants, are very numerous and varied.

The subterranean trunk or stem of any strong-growing herbaceous Fern shows a similar structure. Most Ferns are circinate in the bud ; that is, are rolled up in the manner shown in Fig. 197. Uncoiling as they grow, they have some likeness to a crosier. 487. The fructification of Ferns is borne on the back or under side of the leave" The early botanists thought this such a peculiarity that they 606 607 always called a Fern-leaf a FROND, and its petiole a STIPE. Usage con- tinues these terms, although they are superfluous. The fruit of Ferns consists of SPORE-CASES, technically SPORANGIA, which grow out of the veins of the leaf. Sometimes these are distributed over the whole lower Fio. 501. The Walking-Fern, Camptosorus, reduced in size, showing its fruit- dots on the veins approximated in pairs. 502.

Commonly the spore-cases occupy only detached spots or iines, each of which is called a SOKUS, or in English merely a Fruit-dot. In many Ferns these fruit-dots are naked ; in others they are produced under a scale-like bit of membrane, called an INDUSIUM. In Maidenhair-Ferns a little lobe of the leaf is folded back over each fruit-dot, to serve as its shield or indusium. In the true Brake or Bracken (Pteris) the whole edge of the fruit-bearing part of the leaf is folded back over it like a hem. 488. The form and structure of the spore-cases can be made out with a common hand magnifying glass. The commonest kind (shown in Fig. 503) has a stalk formed of a row of jointed cells, and is itself composed of a layer of thin-walled cells, but is incompletely surrounded by a border of thicker-walled cells, forming the RING. This extends from the stalk up one side of the spore-case, round its summit, descends 011 the other side, but there gradually vanishes. In ripening and drying the shrinking of the cells of the ring on the outer side causes it to straighten ; in doing so it tears the spore-case open on the weaker side and discharges the minute spores that fill it, com- monly with a jerk which scatters them to the wind. Another kind of spore-case (Fig. 507) is stalkless, and has its ring-cells forming a kind of cap at the top : at ma- turity it splits from top to bottom by a regular dehiscence. A third kind is of firm texture and opens across into two valves, like a clam-shell (Fig. 508): this kind makes an approach to the next family. 489. The spores germi- nate on moistened ground. In a conservatory they may be found germinating on a damp wall or on the edges of a well-watered flower-pot. Instead of directly forming a fern-plautlet, the spore grows first into a body which FIG. 509.

[SECTION 17. closely resembles a small Liverwort. This is named a PROTHJLLLUS (Fig. 509) : from some point of this a bud appears to originate, which produces the first fern-leaf, soon followed by a second and third, and so the stem %nd leaves of the plant are set up. 490. Investigation of this prothallus under the microscope resulted in the disoovary of a wholly unsuspected kind of fertilization, taking place at this germinating stage of the plant. On the under side of the prothallus two kinds of organs appear (Fig. 510). One may be likened to an open and depressed ovule, with a single cell at bottom answering to nucleus ; the other, to an anther; but instead of pollen, it discharges corkscrew- shaped microscopic filaments, which bear some cilia of extreme tenuity, by the rapid vibration of which the filaments move freely over a wet surface. These filaments travel over the surface of the prothallus, and even to other prothalli (for there are natural hybrid Ferns), reach and enter the ovule- Pio. 511.

This thereupon sets up a growth, forms a vegetable bud, and so develops the new plant. 491. Au essentially similar process of fertilization has been discovered in the preceding and the following families of Pteridophytes ; but it is mostly subterranean and very difficult to observe. 492. Club-Mosses or Lycopodiums. Some of the common kinds, called Ground Pine, are familiar, being largely used for Christmas wreaths and other decoration. They are low evergreens, some creeping, all with considerable wood in their stems : this thickly beset with small leaves. In the axils of soce of these leaves, or more commonly, in the axils of pecu- liar leaves changed into bracts (as in Fig. 511, 512) spore-cases appear, as roundish or kidney-shaped bodies, of firm texture, opening round the top into two valves, and discharging a 'great quantity of a very fine yellow powder, the spores. 493. The Selaginellas have been separated from Lycopodium, which they much resemble, because they produce two kinds of spores, in sepa- rate spore-cases. One kind (MICKOSPOBES) is just that of Lycopodium ; the other consists of only four large spores (MACKO- SPORES), in a spore-case which usually breaks in pieces at maturity (Fig. 513-515). 494. The Qum\rorts, Isoetes (Tig. 516-519), are very unlike Club Mos- ses in aspect, but have been associated with them. They look more like Rushes, and live in water, or partly out of it. A very short stem, like a corm, bears a cluster of roots underneath ; above it is covered by the broad bases of a cluster of awl- shaped or thread-shaped leaves. The spore-cases are immersed in the bases of the leaves. The outer leaf-bases contain numerous macrospores ; the inner are filled with innu- merable ttjicrospores. 495. The Kllworts (Marsilia and Pilularia) are low aquatics, which FIG. 520. Plant of Marsilia quadrifoliata, reduced in size ; at the right a pair of sporo-carps of about natural size. 162 CRYPTOGAMOUS OR FLOWERLESS PLANTS.

The leaves of the commoner species of Marsilia might be taken for four-leaved Clover. (See Fig. 520.) The sporocarps are usually raised on a short stalk. Within they are divided lengthwise by a partition, and then crosswise by several partitions. These partitions bear numerous delicate sacs or spore-cases of two kinds, intermixed. The larger ones contain each a large spore, or macrospore ; the smaller contain numerous microspores, immersed in mucilage. At maturity the fruit bursts or splits open at top, and the two kinds of spores are discharged. The large ones in germination produce a small prothallus ; upon which the contents of the microspores act in the same way as iu Ferns, and with a similar result 496. Azolla is a little floating plant, looking like a small Liverwort or Moss. Its branches are covered with minute and scale-shaped leaves. On the under side of the branches are found egg-shaped thin- walled sporo- carps of two kinds. The small ones open across and discharge micro- spores ; the larger burst irregularly, and bring to view globose spore-cases, attached to the bottom of the sporocarp by a slender stalk. These delicate spore-cases burst and set free about four macrospores, which are ferti. lized at germination, in the manner of the Pillworts and Quillworts. (See Fig. 521-526.) 521 497. Cellular Cryptogams (483) are so called because composed, even in their higher forms, of cellular tissue only, without proper wood- cells or vessels. Many of the lower kinds are mere plates, or ribbons, or simple rows of cells, or even single cells. But their highest orders follow the plan of Ferns and phanerogamous plants in having stem and leaves for their upward growth, and commonly roots, or at least rootlets, FIG. 521.

Biyophyta, Bryophytes in English form, Bryum being the Greek name of a Moss. These plants are of two principal kinds : true Mosses (Musci, which is their Latin name in the plural) ; and Hepatic Mosses, or Liverworts (Hepatictg). 499. Mosses or Musoi. The pale Peat-mosses (species of Sphagnum, the principal component of sphagnous bogs) and the strong-growing Hair- cap Moss (Polytrichum) are among the lar- ger and commoner representatives of this numerous family ; while Fountain Moss (Fon- tinalis) in running water sometimes attains the length of a yard or more. On the other hand, some are barely individually distinguishable to the naked eye. Fig. 52?' represents a com- mon little Moss, enlarged to about twelve times its natural size ; and by its side is part of a leaf, much magnified, showing that it is composed of cellular tissue (parenchyma-cells) only. The leaves of Mosses are always sim- ple, distinct, and sessile on the stem. The fructification is an urn-shaped spore-case, in this as in most cases raised on a slender stalk. The spore-case loosely bears on its summit a tliin and pointed cap, like a candle-extin- guisher, called a Calyptra. Detaching this, it is found that the spore-case is like a pyxis (376), that is, the top at maturity comes off as a lid (Operculum) ; and that the interior is filled with a green powder, the spores, which are discharged through the open mouth. In most Mosses there is a fringe of one or two rows of teeth or membrane around this month 628 B27 or orifice, the Peristone. When moist the peristome closes hygrometri- cally over the orifice more or less; when drier the teeth or processes commonly bend outward or recurve ; and then the spores more readily es- cape. In Hair-cap Moss a membrane is stretched quite across the mouth, like a drum-head, retaining the spores until this wears away. See Figures 527-541 for details. 500. Fertilization in Mosses is by the analogues of stamens and pistils, which are hidden in the axils of leaves, or in the cluster of leaves at the Flo. 527o Single plant of Physcomitrium pyriforme, magnified. 628.

The analogue of the anther (Antheridium) is a cellulai sac, which in bursting discharges innumerable delicate cells floating in a mucilaginous liquid; each of these bursts and sets free a vibratile self- 681 84 Ml 640 moving thread. These threads, one or more, reach the orifice of the pistil, shaped body, the Pistillidium, and act upon a particular cell at its base within. This cell in its growth develops into the spore-case and its stalk (when there is any), carrying on its summit the wall of the pistillidium, which becomes the calyptra. 501. Liverworts or Hepatio Mosses (Hepaticee) in some kinds re- semble true Mosses, having distinct stem and leaves, although their leaves occasionally run together ; while in others there is no distinction of stem and leaf, but the whole plant is a leaf-like body, which produces rootlets on the lower face and its fructification on the upper. Those of the moss-like kind (sometimes called Scale-Mosses) have their tender spore-cases splitting into four valves ; and with their spores are intermixed some slender spiral FIG. 529.

Marchantia, the commonest and largest of the true Liverworts, forms large green plates or fronds on damp and shady ground, and sends up from some part of the upper face a stout stalk, ending in a several-lobed umbrella-shaped body, under the lobes of which hang several thin-walled spore-cases, which burst open and discharge spores and elaters. Riccia natans (Fig. 545) consists of wedge-shaped or heart-shaped fronds, which float free in pools of still water. The under face bears copious rootlets ; in the substance of the upper face are the spore-cases, their pointed tips 544 merely projecting: there they burst open, and discharge their spores. These are comparatively few and large, and are in fours ; so they are very like the macrospores of Pillworts or Quillworts. 503. ThaUophyta, or Thallophytes in English form. This is the name for the lower class of Cellular Cryptogams, plants in which there is no marked distinction into root, stem, and leaves. Roots in any proper sense they never have, as organs for absorbing, although some of the larger Seaweeds (such as the Sea Colander, Fig. 553) have them as holdfasts. Instead of axis and foliage, there is a stratum of frond, in such plants commonly called a THALLUS (by a strained use of a Greek and Latin word which means a green shoot or bough), which may have any kind of form, leaf-like, stem-like, branchy, extended to a flat plate, or gathered into a sphere, or drawn out into threads, or reduced to a single row of cells, or even reduced to single cells. Indeed, Thallophytes are so multifarious, so numerous hi kinds, so protean in their stages and transformations, so re- condite in their fructification, and many so microscopic in size, either of FIG. 542.

[SECTION 17. the plant itself or its essential organs, that they have to be elaborately described in separate books and made subjects of special study. 504-. Nevertheless, it may be well to try to give some general idea of what Algse and Lichens and Fungi are. Linnaeus had them all under the orders of Algse and Fungi. Afterwards the Lichens were separated ; but 645 646 647 549 of late it has been made most probable that a Lichen consists of an Alga and a Fungus conjoined. At least it must be so in some of the ambiguous Forms. Botanists are in the way of bringing out new classifications of the Thallophytes, as they come to understand their structure and relations better. Here, it need only be said that 505. Lichens live in the air, that is, on the ground, or on rocks, trunks, walls, and the like, and grow when moistened by rains. They assimilate air, water, and some earthy matter, just as do ordinary plants. Algse, or Sea- weeds, live in water, and live the same kind of life as do ordinary plants. Fungi, whatever medium they inhabit, live as animals do, upon organic mat- ter, upon what other plants have assimilated, or upon the products of FIG. 545, 546.

True as these general distinctions are, it is no less true that these orders run together in their lowest forms ; and that Algse and Fungi may be traced down into forms so low and simple that no clear line can be drawn between them ; and even into forms of which it is uncertain whether they should be called plants or animals. It is as well to say that they are not high enough in rank to be distinctively either the one or the other. On the other hand there is a peculiar group of plants, which in simplicity of composition resemble the simpler Algse, while in fructification and in the arrangements of their simple cells into stem and branches they seem to be of a higher order, viz. : 506. Characea9. These are aquatic herbs, of considerable size, abound- ing in poud. The simpler kinds (Nitella) have the stem formed of a single row of tubular cells, and at the nodes, or junction of the cells, a whorl of similar branches. Chara (Fig. 550-552) is the same, except that the cells which make up the stem and the principal branches are strength- ened by a coating of many smaller tubular cells, applied to the surface of the main or central cell. The fructifi cation consists of a globular sporocarp of considerable size, which is spirally enwrapped by tubular cells twisted around it: by the side of this is a smaller and globular autheridium. The latter breaks up into eight shield- Fia 553. Agarum Turneri, Sea Colander (so called from the perforations with which the frond, as it grows, becomes riddled); very much reduced in size.

[SECTION 17. shaped pieces, with an internal stalk, and bearing long and ribbon -shaped filaments, which consist of a row of delicate cells, each of which dis- charges a free-moving microscopic thread (the analogue of the pollen or pollen-tube), nearly in the manner of Ferns and Mosses. One of these threads reaches and fertilizes a cell at the apex of the nucleus or solid body of the sporocarp. This subsequently germinates and forms a new individual. 507. Algse or Seaweeds. The proper Seaweeds may be studied by the aid of Professor Farlow's " Marine Algse of New England ; " the 556 fresh-water species, by Prof. H. C. Woods's "Fresh- water Algae of North America," a larger and less accessible volume. A few common forms are here very briefly mentioned and illustrated, to give an idea of the family. But they are of almost endless diversity. 508. The common Rockweed (Fucus vesiculosus, Fig. 554, abounding between high and low water mark on the coast), the rarer Sea Colander (Agarutn Turneri, Fig. 553), and Laminaria, of which the larger forms are called Devil's Aprons, are good representatives of the olive green or brownish Seaweeds. They are attached either by a disk-like base or by root-like holdfasts to the rocks or stones on which they grow. 509. The hollow and inflated places in the Fucus vesiculosus or Rock- weed (Fig- 554) are air-bladders for buoyancy. The fructification forms in the substance of the tips of the frond : the rough dots mark the places where the conceptacles open. The spores and the fertilizing cells are in different plants. Sections of the two kinds of conceptacles are given in Fig. 555 and 556. The contents of the conceptacles are discharged through PIG. 555.

The large spores are formed eight together in a mother-cell. The minute motile filaments of the antheridia fertilize the large spores after injection into the water: and then the latter promptly acquire a cell- wall and germinate. 510. The Florideae or Rose-red series of marine Algae (which, however, are sometimes green or brownish) are the most attractive to amateurs. The delicate Porphyra or Laver is in some countries eaten as a delicacy, and the cartilaginous Chondrus crispus has been largely used for jelly. Besides their conceptacles, which contain true spores (Fig. 560), they mostly have a fructifi- cation in Tetraspores, that is, of spores originating in fours (Fig. 559). 511. The Grass-green Alga? sometimes form broad membranous fronds, such as those of the common Ulva of the sea-shore, but most of them form icre threads, either simple or branched. To this division belong almost FIG. 557.

[SECTION 17 all the Fresh-water Algse, such as those which constitute the silky threads or green slime of running streams or standing pools, and which were .all called Confervas before their immense diversity was known. Some are formed of a single row of cells, developed each from the end of another. Others branch, the top of one cell producing more than one new one (Fig. 564). Others, of a kind which is very common in fresh water, simple threads made of a line of cells, have the chlorophyll and protoplasm of each cell ar- ranged in spiral lines or bands. They form spores in a peculiar way, which gives to this family the designation of conjugating Alg. 512. At a certain time two par- allel threads approach each other more closely ; contiguous parts of a cell of each thread bulge or grow out, and unite when they meet ; the cell-wall partitions between them are absorbed so as to open a free commu- nication; the spiral band of green matter in both cells breaks up ; the whole of that of one cell passes over into the other ; and of the united contents a large green spore is formed. Soon the old cells decay, and the spore FIG. 564.

Fig. 565 represents several stages of the conjugating process, which, however, would never be found all together like this in one pair of threads. 513. Desinids and Diatomes, which are microscopic one-celled plants of the same class, conjugate in the same way, as is shown in a Closterium bj Fig. 566, 567. Here the whole living contents of two individuals are in- corporated into one spore, for a fresh start. A reproduction which costs the life of two individuals to make a single new one would be fatal to the species if there were not a provision for multiplication by the prompt divi- sion of the new-formed individual into two, and these again into two, and so on in geometrical ratio. And the costly process would be meaningless if there were not some real advantage in such a fresh start, that is, ia 574 514. There are other Algae of the grass-green series which consist of single cells, but which by continued growth form plants of considerable size. Three kinds of these are represented in Fig. 568-574. 515. Lichens, Latin Lichenes, are to be studied in the works of the late Professor Tuckermau, but a popular exposition is greatly needed. The subjoined illustrations (Fig. 575-580) may simply indicate what some of the commoner forms are like.

Most Lichens are flat expansions of grayish hue ; some of them foliaceous in textnre, but never of bright green color; more are crusta- ceous ; some are wholly pulverulent and nearly formless. But in several the vegetation lengthens into an axis (as in Fig. 5 SO), or imitates stem 573 580 and branches or threads, as in the Reindeer-Moss on the ground in our northern woods, and the Usnea hanging from the boughs of old trees overhead. 516. Fungi For this immense and greatly diversified class, it must here suffice to indicate the parts of a Mushroom, a Sphseria, and of one or two common Moulds. The true vegetation of common Fungi consists of slender cells which form what is called a Mycelium. These filamentous FIG. 575.

In a Mushroom (Agaricus), a knobby mass is at length formed, which develops into a stout stalk (Stipe), bearing the cap (Pileus") : the under side of the cap is covered by the Hymenium, in this genus consisting of radiating plates, the gills or Lamella; aud these bear the powdery spores in immense numbers. Under the microscope, the gills are found to be studded with projecting cells, each of which, at the top, produces four stalked spores. These form the powder which collects on a sheet of paper upon which a mature Mushroom is allowed to rest for a day or two. (Fig. 581-586.) 517. The esculent Morel, also Sphseria (Fig. 585, 586), and many other Fungi bear their spores in sacs (asci) exactly in the manner of Lichens 518. Of the Moulds, one of the commoner is the Bread Mould (Fig. 587). In fruiting it sends up a slender stalk, which bears a globular sac ; FIG. 581. Agaricus campestris, the common edible Mushroom. 582.

CLASSIFICATION AND NOMENCLATIVE. 519. Classification, in botany, is the consideration of plants in respect to their kinds and relationships. Some system of Nomenclature, or nam- ing, is necessary for fixing and expressing botanical knowledge so as to make it available. The vast multiplicity of plants and the various degrees of their relationship imperatively require order and system, not only as to names for designating the kinds of plants, but also as to terms for defining their differences. Nomenclature is concerned with the names of plants. Terminology supplies names of organs or parts, and terms to designate their differences. 1. KINDS AND RELATIONSHIP. 520. Plants and animals have two great peculiarities : 1st, they form themselves ; and 2d, they multiply themselves. They reproduce their kind in a continued succession of 521. Individuals. Mineral things occur as masses, which are divisible into smaller and still smaller ones without alteration of properties. But organic things (vegetables and animals) exist as individual beings. Each owes its existence to a parent, and produces similar individuals in its turn. So each individual is a link of a chain; and to this chain the natural- historian applies the name of 522. Species. All the descendants from the same stock therefore com- pose one species. And it was from our observing that the several sorts of plants or animals steadily reproduce themselves, or, in other words, keep up a succession of similar individuals, that the idea of species originated. There are few species, however, in which man has actually observed the succession for many generations. It could seldom be proved that all the White Pine trees or White Oaks of any forest came from the same stock. But observation having familiarized us with the general fact that indi- viduals proceeding from the same stock are essentially alike, we infer from their close resemblance that these similar individuals belong to the same species. That is, we infer it when the individuals are as much like each other as those are which we know, or confidently suppose, to have sprung from the same stock. 523. Identity in species is inferred from close similarity in all essential respects, or whenever the differences, however considerable, are not known or reasonably supposed to have been originated in the course of time under changed conditions. No two individuals are exactly alike ; a tendency to variation pervades all living things. In cultivation, where variations are looked after and cared for, very striking differences come to light ; and if in wild nature they are less common or less conspicuous, it is partly be- cause they are uncared for. When such variant forms are pretty well marked they are called 176 CLASSIFICATION. [SECTION 18. 524. Varieties. The White Oak, for example, presents two or three varieties in the shape of the leaves, although they may be all alike upon each particular tree. The question often arises, and it is often hard to answer, whether the difference in a particular case is that of a variety, or is specific. If the former, it may commonly be proved by finding such intermediate degrees of difference in various individuals as to show that no clear distinction can be drawn between them ; or else by observing the variety to vary back again in some of its offspring. The sorts of Apples, Pears, Potatoes, and the like, show that differences which are permanent in the individual, and continue unchanged through a long series of gen- erations when propagated by division (as by offsets, cuttings, grafts, bulbs, tubers, etc.), are not likely to be reproduced by seed. Still they sometimes are so, and perhaps always tend in that direction. For the fundamental law in organic nature is that offspring shall be like parent. RACES are such strongly marked varieties, capable of coming true to seed. The different sorts of Wheat, Maize, Peas, Radishes, etc., are familiar examples. By selecting those individuals of a species which have developed or inherited any desirable peculiarity, keeping them from min- gling with their less promising brethren, and selecting again the most promising plants raised from their seeds, the cultivator may in a few generations render almost any variety transmissible by seed, so long as it is cared for and kept apart. In fact, this is the way the cultivated domesti- cated races, so useful to man, have been fixed and preserved. Races, in fact, can hardly, if at all, be said to exist independently of man. But man does not really produce them. Such peculiarities often surprising enough now and then originate, we know not how (the plant sports, as the gardeners say) ; they are only preserved, propagated, and generally further developed, by the cultivator's skilful care. If left alone, they are likely to dwindle and perish, or else revert to the original form of the species. Vegetable races are commonly annuals, which can be kept up only by seed, or herbs of which a succession of generations can be had every year or two, and so the education by selection be completed without great lapse of time. But all fruit-trees could probably be fixed into races in an equal number of generations. BUD-VARIETIES are those which spring from buds instead of seed. They are uncommon to any marked extent. They are sometimes called Sports, but this name is equally applied to variations among seedlings. CROSS-BREEDS, strictly so-called, are the variations which come from cross-fertilizing one variety of a species with another. HYBRIDS are the varieties, if they may be so called, which come from the crossing of species (331). Only nearly related species can be hybridized; and the resulting progeny is usually self-sterile, but not always. Hybrid plants, however, may often be fertilized and made prolific by the pollen of one or the other parent. This produces another kind of cross-breeds. 525. Species are the units in classification. Varieties, although of SECTION 18.] KINDS AND RELATIONSHIP. 177 utmost importance In cultivation and of considerable consequence in the flora of any country, are of less botanical significance. For they are apt to be indefinite and to shade off one form into another. But species, the botanist expects to be distinct. Indeed, the practical difference to the botanist between species and varieties is the definite limitation of the one and the indefiniteness of the other. The botanist's determination is partly a matter of observation, partly of judgment. 526. In an enlarged view, varieties may be incipient species ; and nearly related species probably came from a common stock in earlier times. For there is every reason to believe that existing vegetation came from the more or less changed vegetation of a preceding geological era. However that may be, species are regarded as permanent and essentially unchanged in their succession of individuals through the actual ages. 527. There are, at nearly the lowest computation, as many as one hun- dred thousand species of phanerogamous plants, and the cryptogamous species are thought to be still more numerous. They are all connected by resemblances or relationships, near and remote, which show that they are all parts of one system, realizations in nature, as we may affirm, of the con- ception of One Mind. As we survey them, they do not form a single and connected chain, stretching from the lowest to the highest organized species, although there obviously are lower and higher grades. But the species throughout group themselves, as it were, into clusters or constel- lations, and these into still more comprehensive clusters, and so on, with gaps between. It is this clustering which is the ground of the recognition of kinds of species, that is, of groups of species of successive grades or degree of generality ; such as that of similar species into Genera, of genera into Families or Orders, of orders into Classes. In classification the se- quence, proceeding from higher or more general to lower or special, is always CLASS, ORDER, GENUS, SPECIES, VARIETY (if need be). 528. Genera (in the singular, Genus) are assemblages of closely related species, in which the essential parts are all constructed on the same partic- ular type or plan. White Oak, Red Oak, Scarlet Oak, Live Oak, etc., are so many species of the Oak genus (Latin, Quercus). The Chestnuts compose another genus; the Beeches another. The Apple, Pear, and Crab are species of one genus, the Quince represents another, the various species of Hawthorn a third. In the animal kingdom the common cat, the wild-cat, the panther, the tiger, the leopard, and the lion are species of the cat kind or genus ; while the dog, the jackal, the differed species of wolf, and the foxes, compose another genus. Some genera are represented by a vast number of species, others by few, very many by only one known species. For the genus may be as perfectly represented in one species as in several, although, if this were the case throughout, genera and species would of course be identical. The Beech genus and the Chestnut genus would be just as distinct from the Oak genus even if but one Beech and one Chestnut WPJ-B known ; as Indeed was once the case. 18 17 CLASSIFICATION. [SECTION 18, 529. Orders are groups of genera that resemble each other ; that is, they are to genera what genera are to species. As familiar illustrations, the Oak, Chestaut, and Beech genera, along with the Hazel genus and the Hornbeams, all belong to one order. The Birches and the Alders make another; the Poplars and Willows, another; the Walnuts (with the But- ternut) and the Hickories, still another. The Apple genus, the Quince and the Hawthorns, along with the Plums and Cherries and the Peach, the Raspberry with the Blackberry, the Strawberry, the Rose, belong to a large order, which takes its name from the Rose. Most botanists use the names "Order" and "Family" synonymously; the latter more popularly, as "the Rose Family," the former more technically, as "Order Rosaceee" 530. But when the two are distinguished, as is common in zoology, Family is of lower grade than Order. 531. Classes are still more comprehensive assemblages, or great groups. Thus, in modern botany, the Dicotyledonous plants compose one class, the Monocotyledonous plants another (36-40). 532. These four grades, Class, Order, Genus, Species, are of universal use. Variety comes in upon occasion. For, although a species may have no recognized varieties, a genus implies at least one species belonging to it ; every genus is of some order, and every order of some class. 533. But these grades by no means exhaust the resources of clas- sification, nor suffice for the elucidation of all the distinctions which botanists recognize. In the first place, a higher grade than that of class is needful for the most comprehensive of divisions, that of all plants into the two Series of Phanerogamous and Cryptogamous (6) ; and in natu- ral history there are the two Kingdoms or Realms, the Vegetable and the Animal. 534. Moreover, the stages of the scaffolding have been variously ex- tended, as required, by the recognition of assemblages lower than class but higher than order, viz. Subclass and Cohort ; or lower than order, a Sub- order; or between this and genus, a Tribe ; or between this and tribe, a Subtribe ; or between genus and species, a Subgenus ; and by some a species has been divided into Subspecies, and a variety into Subvarieties. Last of all are Individuals. Suffice it to remember that the following are the principal grades in classification, with the proper sequence ; also that only those here printed in small capitals are fundamental and universal in botany: SERIES, CLASS, Subclass, Cohort, ORDEB, or FAMILY, Suborder, Tribe, SubtrtDe, GENUS, Subgenus or Section, SPECIES, Variety, SECTION 18. J NOMENCLATURE. 179 { 2. NAMES, TERMS, AND CHARACTERS. 535. The name of a plant is the name of its genus followed by that of the species. The name of the genus answers to the surname (or family name) ; that of the species to the baptismal name of a person. Thus Quer. cus is the name of the Oak genus; Quercus alba, that of the White Oak, Q. rubra, that of Red Oak, Q. nigra, that of the Black-Jack, etc. Botani- cal names being Latin or Latinized, the adjective name of the species comes after that of the genus. 536. Names of Genera are of one word, a substantive. The older ones are mostly classical Latin, or Greek adopted into Latin; such as Quercus for the Oak genus, Fagus for the Beech, Corylus, the Hazel, and the like. But as more genera became known, botanists had new names to make or borrow. Many are named from some appearance or property of the flowers, leaves, or other parts of the plant. To take a few examples from the early pages of the " Manual of the Botany of the Northern United States," the genus Hepatica comes from the shape of the leaf, resembling that of the liver. Myosurus means mouse-tail. Delphinium is from del- phin, a dolphin, and alludes to the shape of the flower, which was thought to resemble the classical figures of the dolphin. Xanthorrhiza is from two Greek words meaning yellow-root, the common name of the plant. Cimi- cifuga is formed of two Latin words meaning to drive away bugs, i. e. Bugbane, the Siberian species being used to keep away such vermin. Sanguinaria, the Bloodroot, is named from the blood-like color of its juice. Other genera are dedicated to distinguished botanists or promoters of science, and bear their names : such are Magnolia, which commemorates the early French botanist, Magnol ; and Je/ersonia, named after President Jefferson, who sent the first exploring expedition over the Rocky Moun- tains. Others bear the name of the discoverer of the plant ; as, Sarra- cenia, dedicated to Dr. Sarrazin, of Quebec, who was one of the first to send the common Pitcher-plant to the botanists of Europe ; and Ctaytonia, first made known by the early Virginian botanist Clayton. 537. Names of Species. The name of a species is also a single word, appended to that of the genus. It is commonly an adjective, and therefore agrees with the generic name in case, gender, etc. Sometimes it relates to the country the species inhabits ; as, Claytonia Virginica, first made known from Virginia; Sanguinaria Canadensis, from Canada, etc. More com- monly it denotes some obvious or characteristic trait of the species ; as, for example, in Sarracenia, our northern species is named purpurea, from the purple blossoms, while a more southern one is named fava^ because its petals are yellow ; the species of Jeffersonia is called diphylla, meaning two-leaved, because its leaf is divided into two leaflets. Some species are named after the discoverer, or in compliment to a botanist who has made them known ; as, Magnolia Frateri, named after the botanist Fraser, onp 180 NOMENCLATURE. [SECTION 18. of the first to find this species ; and Sarracenia Drummondii, for a Pitcher- plant found by Mr. Drummond in Florida, Such personal specific names are of course written with a capital initial letter. Occasionally some old substantive name is used for the species ; as Magnolia Umbrella, the Um- brella tree, and Ranunculus Flammula. These are also written with a capital initial, and need not accord with the generic name in gender. Geo- graphical specific names, such as Canadensis, Caroliniana, Americana, in the later usage are by some written without a capital initial, but the older usage is better, or at least more accordant with English orthography. 538. Varietal Names, when any are required, are made on the plan of specific names, and follow these, with the prefix var. Ranunculus Flam- mula, var. reptans, the creeping variety: R. abortivus, var. micranthus, the small-flowered variety of the species. 539. In recording the name of a plant it is usual to append the name, or an abbreviation of the name, of the botanist who first published it ; and in a flora or other systematic work, this reference to the source of the name is completed by a further citation of the name of the book, the volume and page where it was first published. So " Ranunculus acris, L.," means that this Buttercup was first so named and described by Lin- nseus ; " R. multifidus, Pursh," that this species was so named and pub- lished by Pursh. The suffix is no part of the name, but is an abbreviated reference, to be added or omitted as convenience or definiteness may re- quire. The authority for a generic name is similarly recorded. Thus, " Ranunculus, L.," means that the genus was so named by Linnaeus ; " Myosurus, Dill.," that the Mouse-tail was established as a genus under this name by Dilleuius ; Caulophyllum, Michx., that the Blue Cohosh was published under this name by Michaux. The full reference in the last- named instance would be, " in Flora Boreali-Americana, first volume, 205th page," in the customary abbreviation, "Michx. Fl. i. 205." 540. Names of Orders are given in the plural number, and are com- monly formed by prolonging the name of a genus of the group taken as a representative of it. For example, the order of which the Buttercup or Crowfoot genus, Ranunculus, is the representative, takes from it the name of Ranunculaceee ; meaning Planta Ranunculaceee when written out in full, that is, Ranunculaceous Plants. Some old descriptive names of orders are kept up, such as Cruciferce for the order to which Cress and Mustard belong, from the cruciform appearance of their expanded corolla, and Umbelliferee, from the flowers being in umbels. 541. Names of Tribes, also of suborders, sabtribes, and the like, are plurals of the name of the typical genus, less prolonged, usually in eee, nea, idea, etc. Thus the proper Buttercup tribe is Ranunculea, of the Clematis tribe, Clematidea. While the Rose family is Rosaceee, the special Rose tribe is Roseee. 542. Names of Classes, eto. For these see the following synopsis of the actual classification adopted, p. 183. SECTION 18.] TERMINOLOGY. 181 543. So a plant is named in two words, the generic and the specific names, to which may be added a third, that of the variety, upon occasion. The generic name is peculiar : obviously it must not be used twice over in botany. The specific name must not be used twice over in the same genus, but is free for any other genus. A Quercus alba, or White Oak, is no hindrance to Betula alba, or White Birch ; and so of other names. 544. Characters and Descriptions. Plants are characterized by a terse statement, in botanical terms, of their peculiarities or distinguishing marks. The character ot the order should include nothing which is com- mon to the whole class U belongs to ; that of the genus, nothing which is common to the orde v ; that of the species nothing which is shared with all other species or the genus; and so of other divisions. Descriptions may enter into complete details of the whole structure. 545. Terminology, also called Glossology, is nomenclature applied to organs or p*\rts, and their forms or modifications. Each organ or special part has ? substantive name of its own : shapes and other modifications of an orgin or part are designated by adjective terms, or, when the forms are peculiar, substantive names are given to them. By the correct use of such botanical terms, and by proper subordination of the characters under the order, genus, species, etc., plants may be described and deter- mined with much precision. The classical language of botany is Latin. While modern languages have their own names and terms, these usually lack the precision of the Latin or Latinized botanical terminology. For. tuuately, this Latinized terminology has been largely adopted and incor- porated into the English technical language of botany, thus securing pre- cision. And these terms are largely the basis of specific names of plants. 546. A glossary or vocabulary of the principal botanical terms used in phanerogamous and vascular cryptogamous botany is appended to this Tolume, to which the student may refer, as occasion arises. 3. SYSTEM. 547. Two systems of classification used to be recognized in botany, the artificial and the natural ; but only the latter is now thought to deserve the name of a system. 548. Artificial classifications have for object merely the ascertaining of the name and place of a plant. They do not attempt to express relation- ships, but serve as a kind of dictionary. They distribute the genera and species according to some one peculiarity or set of peculiarities (just as a dictionary distributes words according to their first letters), disregarding all other considerations. At present an artificial classification in botany is needed only as a key to the natural orders, as an aid in referring an unknown plant to its proper family ; and such keys are still very needful, at least for the beginner. Formerly, when the orders themselves were not clearly made out, an artificial classification was required to lead the 182 SYSTEM. [SECTION 18. student down to the genus. Two such classiflcatious were long in vogie : First, that of Tournefort, founded mainly on the leaves of the flower, the calyx and corolla : this was the prevalent system throughout the first half of the eighteenth century ; but it has long since gone by. It was suc- ceeded by the well-known 549. Artificial System of Linnaeus, which was founded on the sta- mens and pistils. It consists of twenty-four classes, and of a variable number of orders ; the classes founded mainly on the number and dispo- sition of the stamens ; the orders partly upon the number of styles or stig- mas, partly upon other considerations. Useful and popular as this system was down to a time within the memory of still surviving botanists, it is now completely obsolete. But the tradition of it survives in the names of its classes, Monandria, Diandria, Triandria, etc., which are familiar in terminology in the adjective terms monandrous, diandrous, triandrous, etc. (284) ; also of the orders, Monogyuia, Digynia, Trigynia, etc., preserved in the form of monogynous, digynous, trigyuous, etc. (301) ; and in the name Cryptogamia, that of the 24th class, which is continued for the lower series in the natural classification. 550. Natural System. A genuine system of botany consists of the orders or families, duly arranged under their classes, and having the tribes, the genera, and the species arranged in them according to their relation- ships. This, when properly carried out, is the Natural System ; because it is intended to express, as well as possible, the various degrees of relation- ship among plants, as presented in nature; that is, to rank those species and those genera, etc., next to each other in the classification which are really most alike in all respects, or, in other words, which are constructed most nearly on the same particular plan. 551. There can be only one natural system of botany, if by this term is meant the plan according to which the vegetable creation was called into being, with all its grades and diversities among the species, as well of past as 'of the present time. But there may be many natural systems, if we mean the attempts of men to interpret and express that plan, systems which will vary with advancing knowledge, and with the judgment and skill of different botanists. These must all be very imperfect, bear the impress of individual minds, and be shaped by the current philosophy of the age. But the endeavor always is to make the classification answer to Nature, as far as any system can which has to be expressed in a definite and serial arrangement. 552. So, although the classes, orders, genera, etc., are natural, or as natural as the systematist can make them, their grouping or order of arrangement in a book, must necessarily be in great measure artificial. Indeed, it is quite impossible to arrange the orders, or even the few classes, in a single series, and yet have each group stand next to its nearest relatives on both sides. 553. Especially it should be understood that, although phanerogamous SECTION 1S.J SYSTEM. 183 plants are of higher grade than cryptogamous, and angiospermous or or- dinary phanerogamous higher than the gymnospermous, yet there is no culmination in the vegetable kingdom, nor auy highest or lowest order of phanerogamous plants. 554. The particular system most largely used at present in the classi- fication of the orders is essentially the following : SERIES I. PHANEROGAMIA : PHANEROGAMOUS OB. FLOWERING PLANTS. CLASS I. D1COTYLEDONES ANGIOSPERME^J, called for shortness in English, DICOTYLEDONS or DICOTYLS. Ovules in a closed ovary. Embryo dicotyledonous. Stem with exogenous plan of growth.

Some bints and brief instructions for the collection, examination, and preservation of specimens are added. They are especially intended for the assistance of those who have not the advantage of a teacher. They apply to phanerogamous plants and Ferns only, and to systematic botany. 1 fi 1. COLLECTION, OB HERBORIZATION. 556. As much as possible, plants should be examined in the living state, or when freshly gathered. But dried specimens should be prepared for more leisurely examination and for comparison. To the working botanist good dried specimens are indispensable. 557. Botanical Specimens, to be complete, should have root or root- stock, stem, leaves, flowers, both open and hi bud, and fruit. Some- times these may all be obtained at one gathering ; more commonly two or three gatherings at different times are requisite, especially for trees and shrubs. 558. In Herborizing, a good knife and a narrow and strong trowel are needed ; but a very strong knife will serve instead of a trowel or small pick for digging out bulbs, tubers, and the like. To carry the specimens, either the tin box (vasculum) or a portfolio, or both are required. The tin box is best for the collection of specimens to be used fresh, as in the class-room ; also for very thick or fleshy plants. The portfolio is indispensable for long expeditions, and is best for specimens which are to be preserved in the herbarium. 559. The Pasculwm, or Botanical Collecting-box, is made of tin, in shape like a candle-box, only flatter, or the smaller sizes like an English sandwich- case ; the lid opening for nearly the whole length of one side of the box. Any portable tin box of convenient size, and capable of holding specimens a foot or fifteen inches long, will answer the purpose. The box should shut close, so that the specimens may not wilt : then it will keep leafy branches and most flowers perfectly fresh for a day or two, especially if slightly moistened. They should not be wet. 560. The Portfolio is best made of two pieces of solid binder's-board, covered with enamel cloth, which also forms the back, and fastened by straps and buckles. It may be from a foot to twenty inches long, from nine to eleven or twelve inches wide. It should contain a needful quantity of smooth but strong and pliable paper (thin so-called Manilla paper is best), either fastened at the back as in a book, or loose in folded sheets when not very many specimens are required. As soon as gathered, the specimens should be separately laid between the leaves or in the folded sheets, and kept under moderate pressure in the closed portfolio. 1 For fuller directions in many particulars, see "Structural Botany," pp. 370- 874. SECTION 19.] HEEBOEIZATION. 186 561. Of small herbs, especially annuals, the whole plant, root and all, should be taken for a specimen. Of larger ones branches will suffice, with some leaves from near the root. Enough of the root or subterranean part of the plant should be collected to show whether it is an annual, a biennial, or a perennial. Thick roots, bulbs, tubers, or branches of speci- mens intended to be pressed should be thinned with a knife, or cut into slices. Keep the specimens within the length of fifteen or sixteen inches, by folding, or when that cannot be done, by cutting into lengths. 562. For Drying Specimens a good supply of soft and unsized paper is wanted; and some convenient means of applying considerable pressure. To make good dried botanical specimens, dry them as rapidly as possible between many thicknesses of sun-dried paper to absorb their moisture, under as much pressure as can be given without crushing the more delicate parts. This pressure may be had by a botanical press, of which various forms have been contrived; or by weights placed upon a board, from forty to eighty or a hundred pounds, according to the quantity of specimens drying at the time. For use while travelling, a good portable press may be made of thick binders' boards for the sides, and the pressure may be applied by strong straps with buckles. Still better, on some accounts, are portable presses made of wire network, which allow the dampness to escape by evaporation between the meshes. For herborization in a small way, a light wire-press may be taken into the field and made to serve also as a portfolio. 563. It is well to have two kinds of paper, namely, driers of bibulous paper, stitched into pads (or the pads may be of thick carpet-paper, cut to size) and thin smooth paper, folded once ; the specimens to be laid into the fold, either when gathered or on returning from the excursion. These, sheets are to hold the specimens until they are quite dry. Every day, or at first even twice a day, the specimens, left undisturbed in their sheets, are to be shifted into fire-dried or sun-dried fresh driers, and the pressure renewed, while the moist sheets are spread out to dry, so as to take their turn again at the next shifting. This course must be continued until the specimens are no longer moist to the touch. Good and comely specimens are either made or spoiled within the first twenty-four or thirty-six hours. After that, when plenty of driers are used, it may not be necessary to change them so frequently. 664. Succulent plants, which long refuse to part with life and moisture, and Spruces and some other evergreens which are apt to cast off their leaves, may be plunged for a moment into boiling water, all but the flowers. Delicate flowers may be encased in thin tissue paper when put into the press. Thick parts, like the heads of Sun-flowers and Thistles, may be cut in two or into slices. 565. Dried specimens may be packed in bundles, either in folded paper or upon single half-sheets. It is better that such paper should not be bibulous. The packages should be well wrapped or kept in close cases. 186 BOTANICAL WORK. [SECTION 19. 560. Poisoning is necessary if specimens are to be permanently pre- served from the depredatiou of insects. The usual application is an almost saturated solution of corrosive sublimate in 95 per cent alcohol, freely ap- plied with a large and soft brush, or the specimens dipped into some of the solution poured into a large and flat dish; the wetted specimens to be transferred for a short time to driers. 52. HERBARIUM. 567. The botanist's collection of dried specimens, ticketed with their names, place, and time of collection, and systematically arranged under their genera, orders, etc., forms a Hortus Siccus or Herbarium. It com. prises not only the specimens which the proprietor has himself collected, but those which he acquires through friendly exchanges, or in other ways. The specimens of an herbarium may be kept in folded sheets of paper; or they may be fastened on half-sheets of thick and white paper, either by gummed slips, or by glue applied to the specimens themselves. The former is best for private and small herbaria; the latter for large ones which are much turned over. Each sheet should be appropriated to one species ; two or more different plants should never be attached to the same sheet. The generic and specific name of the plant should be added to the lower right-hand corner, either written on the sheet, or on a ticket pasted down; and the time of collection, the locality, the color of the flowers, and any other information which the specimens themselves do not afford, should be duly recorded upon the sheet or the ticket. The sheets of the herbarium should all be of exactly the same dimensions. The herbarium of Linnaeus is on paper of the common foolscap size, about eleven inches long and seven wide. This is too small. Sixteen and three eighths inches by eleven and a half inches is an approved size. 568. The sheets containing the species of each genus are to be placed in genus-coven, made of a full sheet of thick paper (such as the strong- est Manilla-hemp paper), to be when folded of the same dimensions as the species-sheet but slightly wider: the name of the genus is to be writ- ten on one of the lower corners. These are to be arranged under the orders to .which they belong, and the whole kept in closed cases or cabi- nets, either laid flat in compartments, like " pigeon-holes," or else placed in thick portfolios, arranged like folio volumes. All should be kept, as much as practicable, in dust-proof and insect-proof cases or boxes. 569. Fruits, tubers, and other hard parts, too thick for the herbarium, may be kept in pasteboard or light wooden boxes, in a collection apart. Small loose fruits, seeds, detached flowers, and the like may be conven- iently preserved in paper capsules or envelopes, attached to the herbarium ifceeto. SECTION 19.] INVESTIGATION AND DETERMINATION. 187 3. INVESTIGATION AND DETERMINATION OF PLANTS. 570. The Implements required are a band magnifying glass, a pocket lens of an inch or two focus, or a glass of two lenses, one of the lower and the other of the higher power ; and a sharp penknife for dissection. With these and reasonable perseverance the structure of the flowers and fructification of most phanerogamous plants aud Ferns can be made out. But for ease and comfort, as well as for certainty and right training, the student should have some kind of simple stage microscope, and under this make all dissections of small parts. Without it the student will be apt to fall into the bad habit of guessing where he ought to ascertain. 571. The simple microscope may be reduced to a good lens or doublet, of an inch focus, mounted over a glass stage, so that it can be moved up and down and also sidewise, and with (or without) a little mirror under- neath. A better one would have one or two additional lenses (say of half and of a quarter inch focus), a pretty large stage, on the glass of which several small objects can be placed and conveniently brought under the lens ; and its height or that of the lens should be adjustable by a rack- work; also a swivel-mounted little mirror beneath, which is needed for minute objects to be viewed by transmitted light. 572. For dissecting and displaying small parts on the stage of the microscope, besides a thin-bladed knife, the only tools needed are a good stock of common needles of various sizes, mounted in handles, and one or more saddler's-needles, which, being triangular, may be ground to sharp edges convenient for dissection. Also a pair of delicate-pointed forceps ; those with curved points used by the dentist are most convenient. A cup of clean water is indispensable, with which to moisten or wet, or in which occasionally to float delicate parts. Small flowers, buds, fruits, and seeds of dried specimens can be dissected quite as well as fresh ones. They have only to be soaked in warm or boiling water. 573. The compound microscope is rarely necessary except in crypto- gamic botany and vegetable anatomy ; but it is very useful and convenient, especially for the examination of pollen. To the advanced botanist it is a necessity, to all students of botany an aid and delight. 574. Analysis. A few directions and hints may be given. The most important is this : In studying an unknown plant, make a complete ex- amination of all its parts, and form a clear idea of its floral structure and that of its fruit, from pericarp down to the embryo, or as far as the materials in hand allow, before taking a step toward finding out its name and relationship by means of the keys or other helps which the Manuals and Floras provide. If it is the name merely that is wanted, the shorter way is to ask some one who already knows it. To verify the points of structure one by one as they happen to occur in an artificial key, without any preparatory investigation, is a usual but is not the best nor the surest 188 BOTANICAL WORK. [SECTION 19. way. It is well to make drawings or outline sketches of the smaller parts, and especially diagrams of the plaa of the flower, such as those of Fig. 225, 227, 241, 244, 275-277. For these, cross sections of the flower-bud or flower are to be made : and longitudinal sections, such as Fig. 270-274, are equally important. The dissection eveu of small seeds is not difficult after some practice. Commonly they need to be soaked or boiled. 575. The right appreciation of characters and terms used in description needs practice and calls for judgment. Plants do not grow exactly by rule and plummet, and measurements must be taken loosely. Diiference of soil and situation are responded to by considerable variations, and other divergences occur which cannot be accounted for by the surroundings, nor be anticipated in general descriptions. Annuals may be very depauperate in dry soils or seasons, or very large when particularly well nourished. Warm and arid situations promote, and wet ones are apt to diminish pubes- cence. Salt water causes increased succulence. The color of flowers is apt to be lighter in shade, and brighter in open and elevated situations. A color or hue not normal to the species now and then occurs, which nothing in the conditions will account for. A white-flowered variation o/ any other colored blossom may always be expected ; this, though it may be notable, no more indicates a distinct variety of the species than an albino would a variety of the human species. The numerical plan is subject to variation in some flowers ; those on the plan of five may now and then vary to four or to six. Variations of the outline or lobing of leavss are so familiar that they do not much mislead. Only wider and longer observation suf- fices to prevent or correct mistakes in botanical study. But the weighing of evidence and the balancing of pi-obabilities, no less than the use of the well-ordered and logical system of classification, give as excellent training to the judgment as the search for the facts themselves does to the observing powers. f 4 SIGNS AND ABBREVIATIONS. 576. For a full account of these, whether of former or actual use, see " Structural Botany " of the " Botanical Text Book," pp. 367, 392, as also for the principles which govern the accentuation of names. It is needful here to explain only those used in the Manuals and Floras of this country, for which the present volume is an introduction and companion. They are not numerous. 577. In arranging the species, at least those of a large genus, the divi- sions are denoted and graduated as follows : The sign is prefixed to sec- tions of the highest rank : these sections when they have names affixed to them (as PRUNUS CEEASUS) may be called subgenera. When the divi- sions of a genus are not of such importance, or when divisions are mado under the subgenus itself, the most comprehensive ones are marked by as- terisks, * for the first, * * for the second, and so on. Subdivisions are SECTION 19.] SIGNS AND ABBREVIATIONS. 189 marked with a prefixed -i- ; those under this head with ++ ; and those under this with , if there be so many grades. A similar notation is fol- lowed in the synopsis of the genera of an order. 578. The interrogation point is used in botany to indicate doubt. Thus Clematis crispa, L.? expresses a doubt whether the plant in question is really the Clematis crispa of Liuua3us. Clematis ? polypetala expresses a doubt whether the plant so named is really a Clematis. On the other hand the exclamation point (!) is used to denote certainty whenever there is special need to affirm this. 579. For size or height, the common signs of degrees, minutes, and seconds, have been used, thus, 1, 2', 3", stand respectively for a foot, two inches, and three lines or twelfths of an inch. A better way, when such brevity is needed, is to write 1". 2 to . 3 1 . 580. Signs for duration used by Linnaeus were Q for an annual, $ for a biennial, # for a perennial herb, 5 for a shrub or tree. DeCandolle brought in for a plant that died after once flowering, (T) if annual, (2) if biennial. 581. To indicate sexes, $ means staminate or male plant or blossom; 9 , pistillate or female ; K , perfect or hermaphrodite. 582. To save room it is not uncommon to use oo in place of " many ; " thus, " Stamens oo," for stamens indefinitely numerous : "oo flora " for pluriflora or many-flowered. Still more common is the form " Stamens 5-20," or "Calyx 4-5-parted," for stamens from five to twenty, calyx four-parted or five-parted, and the like. Such abbreviations hardly need explanation. 583. The same may be said of such abbreviations as Cat. for calyx, Cor. for corolla, Pet. for petals, St. for stamens, Fist, for pistil, Hab. for habitat, meaning place of growth, Herb, for herbarium, Hort. for garden. Also /. c., loco citato, which avoids repetition of volume and page. 584. "Structural Botany" has six pages of abbreviations of the names of botanists, mostly of botanical authors. As they are not of much consequence to the beginner, while the more advanced botanist will know the names in full, or know where to find them, only a selection is here 190 ABBREVIATIONS OF THE NAMES OF BOTANISTS.

OKAY'S F. F. & 0. BOTANY. w. p. 9 PEEFACE TO THE FIRST EDITION. THIS book is intended to furnish botanical classes and beginners generally with an easier introduction to the plants of this country than the Manual, and one which includes the common cultivated as well as the native species. It is made more concise and simple, first, by the use of somewhat less technical language ; second, by the omis- sion, as far as possible, of the more recondite and, for the present purpose, less essential characters ; and also of most of the obscure, insignificant, or rare plants which students will not be apt to meet with or to examine, or which are quite too difficult for beginners ; such as the Sedges, most Grasses, and the crowd of Golden Rods, Asters, Sunflowers, and the like, which require very critical study. On the other hand, this small volume is more comprehensive than the Manual, since it comprises the common herbs, shrubs, and trees of the Southern as well as the Northern and Middle States, and all which are commonly cultivated or planted, for ornament or use, in fields, gardens, pleasure grounds, or in house culture, including even the conservatory plants ordinarily met with. It is very desirable that students should be able to use exotic as well as indigenous plants in analysis ; and a scientific acquaintance with the plants and flowers most common around us in garden, field, and greenhouse, and which so largely contribute to our well-being and enjoyment, would seem to be no less important than in the case of our native plants. If it is worth while so largely to assemble around us ornamental and useful trees, plants, and flowers, it is cer- tainly well to know what they are and what they are like. To stu- dents in agricultural schools and colleges this kind of knowledge will be especially important. One of the main objects of this book is to provide cultivators, gardeners, and amateurs, and all who are fond of plants and flowers, with a simple guide to a knowledge of their botanical names and 6 6 PREFACE. structure. There is, I believe, no sufficient work of this kind in the English language, adapted to our needs, and available even to our botanists and botanical teachers for whom the only resource is to a botanical library beyond the reach and means of most of these, and certainly quite beyond the reach of those whose needs I have here endeavored to supply, so far as I could, in this small volume. The great difficulties of the undertaking have been to keep the book within the proper compass, by a rigid exclusion of all extraneous and unneces- sary matter, and to determine what plants, both native and exotic, are common enough to demand a place in it, or so uncommon that they may be omitted. It is very unlikely that I can have chosen wisely in all cases and for all parts of the country, and in view of the different requirements of botanical students on the one hand and of practical cultivators on the other the latter commonly caring more for made varieties, races and crosses, than for species, which are the main objects of botanical study. But I have here brought together, within less than 350 pages, brief and plain botanical descriptions or notices of 2650 species, belonging to 947 genera ; and have constructed keys to the natural families, and analyses of their contents, which I hope may enable students, who have well studied the First Lessons, to find out the name, main char- acters, and place of any of them which they will patiently examine in blossom, and, when practicable, in fruit also. If the book answers its purpose reasonably well, its shortcomings as regards cultivated plants may be made up hereafter. As to the native plants omitted, they are to be found, and may best be studied, in the Manual of the Botany of the Northern United States, and in Chapman's Flora of the Southern United States. This book is designed to be the companion of the First Lessons in Botany, which serves as grammar and dictionary ; and the two may be bound together into one compact volume, forming a comprehensive School Botany. For the account of the Ferns, and the allied families of Cryptoga- mous Plants I have to record my indebtedness to Professor D. C. Eaton of Yale College. These beautiful plants are now much cul- tivated by amateurs; and the means here so fully provided for studying them will doubtless be appreciated. HARVARD UNIVERSITY HERBARIUM, Cambridge, Mass., August 29, 1868. PREFACE TO THE REVISION. THREE motives have dominated the course of this revision ; First, to preserve, so far as possible, the method of the original ; it is still Asa Gray's botany, and the reviser has attempted nothing more than to bring it down to date. Second, it is a companion to the Manual, and, therefore, the nomenclature is made to conform strictly with that volume ; and the authorities have been added for the purpose of identifying the names, and to distinguish them from other systems of nomenclature which are now advocated. Third, it is primarily a school book, and there has been no attempt to include either all the wild or all the cultivated plants of its territory, but rather to consider those species which are most readily accessible for demonstration, and which are most likely to attract the attention of a beginner in botany. If it is said that many conspicuous wild plants are omitted, the reviser will answer that all such plants are described in the Manual, and Chapman's Flora of the Southern States, while there is no other account of our domesticated flora. Therefore, in cases of doubt as to the relative importance, to this volume, of wild and cultivated species, the cultivated rather than the native plants have been inserted. A preliminary draft of this revision, through the family Legumi- nosae, was made by Professor Charles R. Barnes, of the University of Wisconsin, of which I have been glad to avail myself. L. H.

The signs for degrees, minutes, and seconds are used for feet, inches, and lines, the latter twelve to the inch. Thus 1 means a foot in length or height, &c. ; 2', two inches ; 6", five lines, or five-twelfths of an inch. The dash between two figures, as 5- 10 means from five to ten, &c. The character oo means many. Fl. stands for flowers or flowering. Cult, stands for cultivated. Nat. stands for naturalized. N., E., S., W. stand for North, East, South, and West. The geographical abbreviations, such as Eu. for Europe, and the com- mon abbreviations for the names of the States, need no particular expla- nation. Species printed in heavy-faced Roman type are indigenous to some part of our territory (the U. S., East of the 100th meridian). Those in heavy-faced Italic type are not indigenous to this territory, and they exist in our region only in cultivation or as introduced weeds. The species and varieties in SMALL CAPITAL ROHAN LETTERS are hor- ticultural forms or hybrids. When in parenthesis, they are simply synonyms. Pronunciation. In accordance with the usage in Gray's botanies, it is intended that the Latin names in this volume shall be pronounced after the English method. The accent marks designate both the accentuation (or most emphatic syllable), and the length of the vowel. The grave (*) designates a long vowel, and the acute (') a short one. The letters <n", like to, representing the Greek ending -oe5ijs, should properly be pro- nounced separately. If the i, in this case, is the penultimate syllable (next to the last) , it should be pronounced long, as in prino-ides, usneo- ides ; but if it is the antepenultimate (third syllable from the end), it is pronounced short, as rhomb o-idea. In names derived from dioicus and monoicus (dioecious and monoecious), oi is a true diphthong, as in choice. 27 28 STATISTICS. The diphthong au is given its customary English sound. The pupil should bear in mind that the final e in the names of plants should always be pronounced (taking the sound of short i), as in officina-le, vulga-re, commu-ne. STATISTICS OF THE REVISION.

NOMENCLATIVE. THE first part of the name of a plant designates the genus to which it belongs, or is generic; the second part belongs to the particular species, or is specific; but both words are necessary for the designation of the plant or species. The literature of systematic botany is so voluminous, however, that, in order to identify the plant names and to aid in tracing them to their origins, it is necessary to cite the author of the name along with the name itself. In accordance with the method in Gray's botanies, this author is understood to be the one who first used the two names together ; that is, he is the author of the com- plete name or combination and not necessarily of either part of it.

SERIES L FLOWERING OR PHJENOGAMOUS PLANTS. Plants bearing true flowers ; that is, having stamens and pistils, and producing seeds containing an embryo. CLASS I. ANGIOSPERMS. Plants having a closed ovary which contains the ovules : includes all but the Pine and Cycas families. SUBCLASS I. DICOTYLEDONS (or EXOGBNS). Distinguished by having the woody strands of the stem in a circle around a pith ; the wood often increasing by yearly layers when the stem is more than one year old ; the embryo with a pair of cotyledons or seed leaves ; leaves generally net-veined; parts of the flower seldom in threes, most commonly in fives or fours. See Lessons, pp. 23, 139. This class includes all our ordinary trees and shrubs, and the greater part of our herbs. I. POLYPETALOUS DIVISION. Includes the families which have, at least in some species, both calyx and corolla, the latter with the petals not united with each other. Yet some plants of almost all these families have apetalous flowers, and in some species the petals are more or less united. GRAY'S F. F. & o. HOT. 3 33 34 CBOWFOOT FAMILY. L EANTTNCULACK41, CROWFOOT FAMILY. Not perfectly distinguished by any one or two particular marks, but may be known, on the whole, by having numerous stamens, and usually more than one pistil, all the parts of the flower distinct, and inserted on the receptacle. The calyx is often colored like a corolla, when the latter is wanting. The bulk of the seed is hard albumen, the embryo being very small. The plants are herbs with an acrid watery juice (not milky or colored), or a few barely shrubby. Many are cultivated for ornament. 1. Sepals valvate, or with their edges turned inward in the bud. Petals none, o\ minute. Leaves opposite, the plants mostly climbing by their leaf -stalks. 1. CLEMATIS. Sepals commonly 4, sometimes several, petal-like. 2. Sepals imbricated in the bud.

Alternate leaves, chiefly compound, entire leaflets, and stipules, are almost universal in this great family. I. PULSE SUBFAMILY. Flower (always on the plan of 5, and stamens not exceeding 10) truly papilionaceous, i.e. the standard outside of and in the bud enwrapping the other petals, or only the standard present in Amorpha.

Trees, shrubs, or herbs with alternate stipulate leaves and regular flowers, with usually indefinite unconnected stamens inserted on the calyx, one, few, or many simple separate pistils (except in the division to which the Pear belongs), and single, few, or occasionally numerous seeds ; these filled with a straight embryo. Calyx usually of 5 sepals, but sometimes reinforced by a row of sepal-like bracts beneath. Petals as many as the sepals, or sometimes wanting. Destitute of noxious qualities (excepting the bark, leaves, and kernels of some Cherries, the Almond, etc.), and furnishing the most important fruits of temperate climates, as well as the queen of flowers. We have three principal great divisions. I. ALMOND or PLUM SUBFAMILY ; consists of trees or shrubs, with simple leaves, stipules free from the petiole (often minute or early deciduous, so that there may appear to be none), a calyx which is deciduous after flowering, and a single pistil, its ovary superior and tipped with a slender style (Lessons, p. 95, Fig. 271), containing a pair of ovules, and becoming a simple drupe or stone-fruit. (Lessons, p. 120, Fig. 375.) 1. PRUNUS. Calyx with a bell-shaped or urn-shaped tube and 5 spreading lobes. Petals 5, and stamens 3-5 times as many, or indefinitely numerous, inserted on the throat of the calyx. Flowers white or rose-color. II. EOSE SUBFAMILY PROPER: consists of herbs or shrubs, with stipules either free from or united with the base of the petiole, calyx persisting below or around the fruit, which is composed of sometimes one, but commonly several or many distinct pistils. 1. Calyx not a fleshy tube or cup, nor closed over the fruit. * Ovaries about 5 (2-12), becoming little pods, mostly several-(\-W-) seeded; calyx with only 5 or rarely 4 lobes. 2. SPIRJ5A.

Myrtus communis, Linn. COMMON MYRTLE. From the Mediter- ranean region ; smooth, with ovate or lance-ovate, opposite, shining leaves, small in the variety usually cultivated ; peduncles in their axils hearing a small white or rose-tinged flower (sometimes full double), fol- lowed by a black berry, containing several kidney-shaped seeds. 2. Eugenia Jambos, Linn. ROSE APPLE. From India ; smooth, with opposite, shining, long, and lanceolate leaves, and clusters of large white flowers, with their long stamens most conspicuous ; the calyx tube dilated and prolonged beyond the ovary, which forms a large edible berry, like a small apple, scentless, but when eaten, of a rose-like savor ; seeds very few, large. 3. Psidium Guyava, Linn. GUAVA. With oval, feather-veined, opposite leaves, pubescent beneath, and one or two white flowers at the end of an axillary peduncle ; the fruit a large and pear-shaped yellowish berry, which is edible, and from which Guava jelly is made in the West Indies. The WHITE, PEAR, and APPLE GTTAVAS are of this species. P. POMf- FERUM and P. pYRfFERUM are forms of this species. The plant is prob- ably native to tropical America, although now widely distributed. P. Cattleianum, Sabine. CATTLE Y GUAVA. Has obovate, and thick, and shining leaves, and a small reddish fruit, which lacks the muskiness of the common sorts. 4. Callistemon lanceolatus, Sweet. Of Australia, called BOTTLE BRUSH, on account of the appearance of the flowers (sessile all round the stem below the later leaves) with their very long, deep red stamens ; the 5 petals small and falling early ; the fruit a small, many-seeded pod, open- ing at the top; the alternate lanceolate leaves remarkable for being turned edgewise by a twist at their base, as in many related Myrtaceous plants of Australia. 176 MELASTOMA FAMILY.

Herbs, some innocent and many of them aromatic, others acrid-narcotic poisons, with small flowers in umbels, calyx adherent to the 2-celled ovary, which has a single ovule hang- ing from the summit of each cell, 5 minute calyx teeth or none, 5 petals, 5 stamens, and 2 styles ; the dry fruit usually splitting into 2 seed-like portions or akenes ; seed with hard albumen and a minute embryo. Eryngiurn and one or two others have the flowers in heads instead of umbels. Stems usually hollow. Leaves alternate, more commonly compound or decompound. Umbels mostly compound; the circle of bracts often present at the base of the general umbel is called the involucre; that at the base of an umbellet, the involucel. The flowers are much alike in all, and the characters are taken from the form of the fruit, and much stress is laid upon the receptacles of aromatic oil (vittce or oil tubes) which are found in most species and' give characteristic flavor. The family is too difficult for the beginner ; so that only the common culti- vated species, and the most conspicuous or noteworthy wild ones are given here. 1.

() 220 COMPOSITE FAMILY. LXI. COMPOSITE, COMPOSITE FAMILY. Herbs, or a very few shrubs, known at once by the " com- pound flower," as it was termed by the older botanists, this consisting of several or many flowers in a head, surrounded by a set of bracts (formerly likened to a calyx) forming an involucre, the stamens as many as the lobes of the corolla (almost always 5) and inserted on its tube, their anthers syngenesious, i.e. united in a ring or tube through which the style passes. (Lessons, Figs. 290, 291.) Calyx with its tube incorporated with the surface of the ovary, its limb or border (named the pappus) consisting of bristles, either rigid or downy, or of teeth, awns, scales, etc., or of a cup or crown, or often none at all. (Lessons, Figs. 379-384.) Corollas either tubular or funnel-form and lobed, or strap-shaped (ligulate), or sometimes both sorts in the same head, when the outermost or marginal row has the strap-shaped corollas, forming rays (which answered to the corolla of the supposed compound flower), the separate flowers therefore called ray flowers; those of the rest of the head, or disk, called disk flowers. The dilated end of the stalk or branch upon which the flowers are borne is called the receptacle. The bracts, if there are any, on the receptacle (one behind each flower) are called the chaff of the receptacle. The bracts or leaves of the involucre out- side the flowers are commonly called scales. Style 2-cleft at the apex. Ovary 1-celled, containing a single ovule, erect from its base, in fruit becoming an akene. Seed filled by the embryo alone. (For the flowers, and the particular terms used in describing them, see Lessons, pp. 93, 94, Figs. 266-269 ; for the fruit, see p. 121, Figs. 379-384.) The largest family of Flowering Plants, generally too diffi- cult for the beginner ; but most of the common kinds, both wild and cultivated, are here briefly sketched. For fuller details as to the wild ones, with all the species, the student will consult the Manual, and Chapman's Southern Flora.

The flowers are rather too difficult for the beginner readily to understand throughout. For a particular study of them the Manual must be used. 1. Erect herbs, with ordinary foliage, and deeply 5-parted calyx and corolla,. Flowers in simple umbels.

GRAY'S F. F. & G. EOT. 26 402 FKOGBIT FAMILY. SUBCLASS II. MONOCOTYLEDONS (or ENDOGENS). Distinguished by having the woody matter of the stem in distinct bundles scattered without obvious order through- out its whyle breadth, never so arranged as all to come in a circle; when abundant enough to. form proper wood, as in Palms and the like, this is hardest and the bundles most crowded toward the circumference. Embryo with a sin- gle cotyledon; the first leaves in germination alternate. Leaves mostly, but not always, parallel-veined. Parts of the flower almost always in threes, never in fives. See Lessons, p. 138, and for style of vegetation, p. 26, Fig. 71. The plants of this class may be arranged under three generally well-marked divisions. I. PETALOIDEOTJS DIVISION. Flowers with a perianth (calyx and corolla) which is usually (except in Rush-like plants) colored, not on a spadix. CXI. HYDROCHARIDACKE, FROGBIT FAMILY. Water plants, with dioecious, monoecious, or polygamous flowers on scape-like peduncles from a sort of spathe of one or two leaves, or sessile, the perianth in the fertile flowers of 6 parts united below into a tube which is coherent with the surface of a compound ovary ; stamens 3-12, sometimes mono- delphous ; stigmas 3 or 6. Fruit ripening under water. Growing under water, the fertile flowers only rising to the surface ; the sterile (not often detected) breaking off their short stalks, and floating on the surf ace around the pistillate flowers. 1. ELODEA. Stems leafy and branching. Fertile flowers rising from a tubular spathe; the perianth prolonged into an exceedingly slender stalk-like tube, 6-lobed at top, commonly bearing 3-9 apparently good stamens ; ovary 1-celled with a few ovules on the walls ; style coherent with the tube of the perianth ; stigmas 3, notched. 2. VALLISNERIA. Stemless ; leaves all in tufts from creeping rootstocks. Fertile flowers with a tubular spathe, raised to the surface of the water on an extremely long and slender scape ; tube of the perianth not prolonged beyond the 1-celled ovary, with 8 obovate outer lobes (sepals) and 8 small inner linear ones (petals), and no stamens. Ovules very numerous, lining the walls. Stigmas 3, sessile, 2-lobed. Fruit cylindrical, berry-like. ORCHIS FAMILY. 403 Floating, spreading by proliferous shoots ; leaves long-petioled, rounded heart- shaped. 8. LIMNOBIUM. Flowers monoecious or dioecious, from sessile or short-stalked leaf-like spathes, the sterile spathe of one leaf surrounding 8 long-pediceled staminate flowers ; the fertile 2-leaved, with one short-pediceled flower. Perianth of 3 outer oval lobes (calyx) and 3 narrow inner ones (petals). A cluster of 6-12 unequal monadelphous stamens in the sterile flower ; some awl-shaped rudiments of stamens and a 6-9-celled ovary in the fertile flower ; stigmas 6-9, each 2-parted. Fruit berry-like, many seeded. 1. ELODEA (or ANACHARIS), WATER WEED. (Greek: marshy.) Flowers summer. 2Z E. Canadensis. Michx. Slow streams and ponds ; a rather homely weed, with long branching stems, beset with pairs or whorls of pellucid and veinless, 1-nerved, minutely serrulate, sessile leaves ('-!' long), varying from linear to ovate-oblong, the thread-like tube of the yellowish perianth often several inches long. 2. VALLISNERIA, TAPE GRASS, EELGRASS of fresh water. (Xamed for A. Vallisneri, an early Italian botanist.) Flowers late summer. If. V. spiralis, Linn. In clear ponds and slow streams, with bright green and grass-like linear leaves (l-2 long), delicately nerved and netted; fertile scapes rising 2-4 long, according to the depth of the water, after- wards coiling up spirally and 'drawing the fruit under water to ripen. The leaves of this and the preceding are excellent to show cyclosis. 3. LIMITOBIUM, FROGBIT. (Greek: living in pools.) Flowers whitish, the fertile ones larger, in summer. 2/ L. Sp6ngia, Richard. Floating free on still water, N. J., W. and S. ; rooting copiously ; leaves l'-2' long, purple beneath, tumid at base, with spongy air cells. CXH. ORCHIDACEJS, OECHIS FAMILY. Herbs, with perfect flowers of peculiar structure, the perianth adherent to the 1-celled ovary (which has numberless minute ovules on 3 parietal placentae), its chiefly corolla-like 6 parts irregular, 3 in an outer set answering to sepals, 3 within and alternate with these answering to petals, one of these, generally larger and always different from the others, called the labellum or lip; the 1 or 2 stamens are gynandrous, being borne on or connected with the style or stigma (Lessons, Fig. 284) ; the pollen is mostly coherent in masses of peculiar appearance, celled pollinia (Lessons, Figs. 320, 321, 322). All perennials, and all depend more or less upon insects for fertilization. Beginners will not very easily comprehend the remarkable structure of most Orchideous flowers. There are numerous 404 ORCHIS FAMILY. species and hybrids in cultivation in choice greenhouses, but only the commonest or most conspicuous wild species are mentioned here. * EPIPHYTE or A IB-PLANT ORCHIDS. Of these a great variety are cultivated in the choicest conservatories. We have one genus in the most Southern States. 1. EPLDENDRUM. The 3 sepals and 2 petals nearly alike and widely spreading ; the odd petal or lip larger and 3-lobed, its base united with the style, which bears a lid-like anther, containing 4-stalked pollen masses, over the glutinous stigma. * TERRESTRIAL ORCHIDS, growing in the soil, in woods or low grounds, but sometimes leafless and parasitic on roots. +- Anther only one, but of 2 cells, which when separated (as in Orchis) must not be mis- taken for two anthers ; pollen collected into one or more masses in each cell ; stigma a glutinous surface. ++Lip, or odd petal, sac-like and inflated. 2. CALYPSO. Sepals and petals nearly similar, lanceolate and pointed. Lip larger than the other parts (j* long), Lady's Slipper-like and hairy inside. Pollen masses 2, waxy, each 2-parted, sessile. Delicate little plant with a 1-flowered scape, and a single radical leaf. ++ ++ Lip neither saccate nor spurred (or spur adnate to the ovary); anther inverted on the apex of the style, commonly attached by a sort of hinge ; pollen 2 or 4 separate soft masses, not attached to a stalk or gland. = Flowers mostly small, dull-colored, in a spike or raceme on a brownish or yellowish leafless scape ; pollen masses 4, globular, soft-waxy. 8. APLECTKTJM. Flowers as in the next, but no trace of a spur or sac, larger. Scape rising from a large solid bulb or conn, which also produces, at a different season, a broad and many-nerved green leaf. 4. COEALLOEHIZA. Flowers with sepals and petals nearly alike ; the lip broader, 2, ridged on the fece below, from its base descending a short sac or obscure spur which adheres to the upper part of the ovary. Scape with sheaths in place of leaves ; the root or rootstock thickish, much branched and coral-like. = = Flowers rather large ; pollen masses soft, of lightly-connected powdery grains. 5. ABETHUSA. Flower only one, on a naked scape ; the 3 sepals and 2 petals lanceolate and nearly alike, all united at the base, ascending and arching over the top of the long and somewhat wing-margined style, on the petal-like top of which rests the helmet-shaped hinged anther, over a little shelf, the lower face of which is the stigma. Lip broad, erect, with a recurving rounded apex and a bearded crest down the face. Pollen masses 4, 2 hi each cell of the anther. 6. CALOPOGON. Flowers 2, 3, or several, in a raceme-like loose spike ; the lip turned towards the axis, diverging widely from the slender (above wing-margined) style, narrower at base, larger and rounded at the apex, strongly bearded along the face. Sepals and the 2 petals nearly alike, lance-ovate, separate and spreading. Anther lid-like; pollen masses 4. 1. POGONIA. Flowers one or few terminating a leaf-bearing stem ; the sepals and petals separate; lip crested or 3-lobed. Style club-shaped, wingless; stigma lateral. Anther lid-like, somewhat stalked ; pollen masses 2, only 1 in each cell. H- ++ ++ Lip not spurred or saccate ; anthers borne on the back of the style, below its tip, erect or inclined ; the ovate stigma on the front. Flowers in a spike, small, white. 8. 8PIRANTHES. Flowers oblique on the ovary, all the parts of the perianth erect or conniving, the lower part of the lip involute around the style and with a callosity on each side of the base, its narrower tip somewhat recurved and crisped. Pollen masses 2 (one to each cell), each 2-parted into a thin plate (composed of grains lightly united by delicate threads), their summits united to the back of a narrow boat-shaped sticky gland set in the beaked tip over the stigma. Leaves not variegated. ORCHIS FAMILY. 405 9. QOODYERA. Flowers like Spiranthes, bat the lip more sac-shaped, closely sessile, and destitute of the callous protuberances at base. Leaves variegated with white veining. ++ -H- ++ -H- Lip produced underneath into a free honey-bearing horn or spur ; pollen of each cell all connected by elastic threads with a central axis or stalk ; the lower- end of which is a sticky gland or disk, by adhesion to which the whole mass of pollen is dragged from the opening anther and carried off by insects. 10. OKCHIS. The 3 sepals and 2 petals are conniving and arched on the upper side of the flower; the lip turned downwards (i.e. as the flower stands on its twisted ovary). Anther erect, its two cells parallel and contiguous ; the 2 glands side by side just over the concave stigma, and inclosed in a sort of pouch or pocket opening at the top. 11. HABENARIA. Flower generally as in Orchis, but the lateral sepals commonly spread- ing ; the glands attached to the pollen masses naked and exposed. t- +- Anthers 2 (Lessons, Fig. 284), borne one on each side of the style, and a trowel- shaped body on the upper side answers to the third stamen, the one that alone is present in other Orchids ; pollen powdery or pulpy ; stigma roughish, not glutinous, 12. CYPRIPEDItJM. Sepals in appearance generally only 2, and petals 2, besides the lip which is a large inflated sac, into the mouth of which the style, bearing the stamens and terminated by the broad terminal stigma, is declined. Pollen sticky on the sur- face, as if with a delicate coat of varnish, powdery or at length pulpy underneath. 1. EFIDENDRUM. (Name in Greek means upon a tree, i.e. an epi- phyte.) E. condpseum. Ait.

CXm. SCITAMLNKE, BANANA FAMILY. A group of tropical or subtropical perennial plants, with leaves having distinct petiole and blade, the latter traversed by nerves running from the midrib to the margin; flowers irregular, with a perianth of at least two ranks of divisions, below all combined into a tube which is adherent to the 3-celled ovary; the stamens 1-6 and distinct. We have two wild representatives on our southeastern borders ; the many culti- vated ones are chiefly grown for their ornamental foliage, and some of them are rarely seen in blossom. They are therefore seldom available for botanical study. I. GINGER SUBFAMILY. Seeds, rootstocks, or roots hot-aromatic. Stamen 1, with a 2-celled anther, commonly embracing the style, but not united with it ; staminodia some- times present. GINGER is the dried rhizomes of ZINGIBER OFFICINALE of the tropics. 1. HEDYCHITTM. Flowers with a slender tube bearing 6 divisions which may be likened to those of an Orchideous flower, one (answering to the lip) much larger and broader than the 5 others, and a very long, protruding, reddish filament terminated by a yellow unappendaged anther sheathing the style up almost to the stigma. II. ARROWROOT or INDIAN SHOT SUBFAMILY. No hot-aromatic properties, the thick rootstocks, etc., com- monly containing much starch, from which genuine arrowroot is produced. Stamen 1, with a 1-celled anther. ARROWROOT is the product of species of MARANTA. BANANA FAMILY. 411 * Capsule \-celledand I -seeded. 2. THALIA. Stemless herbs, with an elongated scape and radical long-stalked leaves. Corolla tubular, the three exterior divisions similar and equal, the interior ones une- qual (the anterior division broad and hooded, one elongated and clawed and one partly adnate to the stamen and furnished with two bristles on one side). Stigma 2-lipped. * * Ovary 3-celled (rarely 2-celled) , the cells \-ovuled. 3. CALATHEA. Strong-growing ornamental-leaved plants with flowers in imbricated bracteate heads or cone-like spikes or rarely in somewhat lax spikes. Outer 3 seg- ments of perianth lanceolate, the 3 inner ones irregular and obtus*. Corolla tube often slender. Staminodia present and petal-like. * * * Capsule %-celled, the cells several-** -seeded. 4. CANNA. Mostly tall plants with showy flowers in an erect spike or raceme terminating the stem. Stamen a petal-like filament with the anther upon one side. III. BANANA SUBFAMILY PBOPEB. Not aromatic or pungent. Stamens 5 with 2-celled anthers, and an abortive naked filament. 5. MUSA.

Thalius, a German botanist, died in 1588.) T. dealbata, Roscoe. Plant dusted over with a white powder ; heart- ovate, long-petioled leaves all from the root ; reed-like scape (3-5 high) branching above into panicled erect spikes of small, much-bracted, purple flowers. Ponds and bogs, S. Car., S. and W. 3. CALATHEA. (Greek: a basket, alluding either to the basket- shaped stigma or to the use of the leaves in basket-making in S. Amer.)

(Name obscure.) The 3 small green leaves which remain on the capsule are the sepals. The showy parts of the flower, inside the petals, are the petal-like staminodia, the upper two or three of which are very prominent. Tropical (mostly American) plants, now much used in lawn decorations. The cultivated forms, which are much confused, are chiefly from the following : * Corolla lobes and staminodia united into a short tube, the two or three upper staminodia being developed. i- Upper staminodia 3.

The Cannas known as C. LIMB\TA or AtREo-viTT\TA (the upper staminodia red bor- dered with yellow), and C. coccfNEA (with red-tinged sepals and petals, and often bordered staminodia) are evidently forms of this species.

C. EHEMANNI of gardens is a hybrid of this and probably C. Warsce- wiczii. The modern race of dwarf and Crozy "flowering" Cannas is mostly sprung from this garden form again crossed, the red-flowered ones being mainly hybrids of C. Ehemanni and C. Warscewiczii, and the yel- low-flowered ones largely of C. Ehemanni and C. glauca. C. liliifldra, Warsc. Similar to C. iridiflora in habit, but the flowers white and fragrant. Not yet common, but it will undoubtedly play an important part in garden forms in the future. 5. MUSA, BANANA, PLANTAIN. (Antonius Musa, physician to Augustus.) M. Sapientum, Linn. BANANA.

Four small families, mostly of rush-like plants, are some- what related to the foregoing, but they are unattractive to the beginner and are rather too recondite for description here. For their study, the Manual should be consulted. These are CXXm. XYRIDACRE, YELLOW-EYED GRASS F. Small, rush-like herbs, with equitant leaves, like Bulrushes in having flowers in a head or spike, one under each firm glume-like bract, but with a regular perianth of 3 sepals and 3 colored (yellow) petals ; also a 1-celled many-seeded ovary and pod with 3 parietal placentae, and a 3-cleft stigma. Over a dozen species of XYKIS in our territory, mostly in boggy places or pine barrens. CXXIV. MAYACR2E, MAYACA FAMILY. Moss-like aquatic plants, densely clothed with narrow-linear, sessile, and pellucid leaves, and bearing axillary, naked, 1- flowered peduncles, the perfect white flower 3-androus. One species, MAYACA MICHAUXII, in shallow water, Va., S. CXXV. ERIOCAULONACEE, PIPEWORT FAMILY. Another small group of marsh or aquatic herbs, of rush-like appearance, with a head of monoecious, white-bearded flowers, in structure somewhat like the Yellow-eyed Grass, terminat- ing a naked scape, at the base of which is a tuft of grassy awl- shaped, linear, or lanceolate leaves of loose cellular texture, not equitant, but the upper surface concave. A half dozen spe- cies in the genera EBIOCAULON, P^EPALANTHUS, LACHNOCAULON. CXXVI. JTTNCACKE, RUSH FAMILY. Plants with the appearance and herbage of Sedges and Grasses, yet with flowers of the structure of the Lily Family, having a complete perianth of 6 parts, 3 outer and 3 inner, but greenish and glume-like. Stamens 6 or 3, style 1 ; stigmas 3. 1. JTTNCUS. Ovary and pod 3-ceUed or almost 3-celled, many-seeded. Herbage smooth ; stems often leafless, generally pithy. 2. LUZULA. Ovary and pod 1-celled, with 8 parietal placentae, and one seed to each. Stems and leaves often soft-hairy. The only conspicuous species is Jtmcus EFFUSUS, Linn., the COMMON BULRUSH, in low grounds ; has soft and pliant stems in clumps, 2-4 high ; panicle of many greenish flowers ; 3 stamens ; and very blunt pod. ARUM FAMILY. 457 II. SPADICEOUS DIVISION. Flowers either naked, i.e. destitute of calyx and corolla, or these, if present, not brightly colored, collected in the sort of spike called a spadix, which is embraced or sub- tended by the kind of developing bract termed a spathe. The most familiar examples of this division are offered by the Arum Family. There are various exceptions to this style of inflorescence, and the division, like all others, is merely artificial, but it will serve to aid the beginner. The first two families are too difficult for the beginner. CXXVH. NAIADACKE, PONDWEED FAMILY. Marsh or aquatic plants with stems mostly leafy and jointed, the leaves stipulate or sheathing, the flowers (sometimes not spathaceous) perfect or unisexual, with 4 or 6 distinct incon- spicuous segments, or the perianth tubular, or even wanting. Stamens 1-6. Ovaries 1-6, distinct or nearly so, 1-celled and usually 1-ovuled, the fruit follicular or fleshy. Our genera are TRIGLOCHIN, SCHEUCHZERIA, with bladeless leaves, allied to the water Plantain Family, the former with naked, scape-like stems ; and POTAMOGETON, the POND WEEDS, with many diffi- cult species, RUPPIA and ZOSTERA, grass-like immersed plants on the seacoast, ZANXICHELLIA, a similar plant in fresh water, and NAIAS, slender and inconspicuous branchy plants, mostly in fresh water. CXXVm. LEMNACEfi, DUCKWEED FAMILY. Minute, stemless plants reduced to a floating leaf-like body three fourths inch or less long (in LEMNA) or even to minute, green grains (in WOLFFIA). The least of flowering plants. CXXIX. ARACILE, ARUM FAMILY. Perennial herbs with pungent or acrid watery juice, leaves often with veins reticulated so as to resemble those of Dicoty- ledons, small perfect or imperfect flowers in a fleshy head or spike called a spadix, usually furnished with the colored or peculiar enveloping bract called a spathe. Floral envelopes 458 ARUM FAMILY. 4-6, or 0. Fruit generally a berry. A large family in the tropics, and comprising many plants of choice collections, cul- tivated for the foliage, or for the showy, so-called "flowers," which are really colored spathes. Plants with expanded leaf blade (never linear), and with spreading nerves or veins. +- Spadix surrounded by a conspicuous, generally colored, spathe. H- Leaves (in ours) compound. 1. ARIS^EMA. Leaves only one or two, with stalks sheathing the simple stem, which rises from a fleshy conn, and terminates in a long spadix bearing nude flowers only at its hase, where it is enveloped by the convolute lower part of the greenish or pur- plish spathe. Sterile flowers above the fertile, each of a few sessile anthers ; the fertile each a 1-celled 5-6-ovuled ovary, in fruit becoming a scarlet berry ; commonly dioecious, the stamens being abortive in one plant, the pistils abortive in the other.

Spadix long and tapering, covered completely with nude flowers, i.e. above with naked shield-shaped anthers each of 5 or 6 cells, opening by a hole at the top, below with 1-celled ovaries bearing several erect ovules, in fruit a 1-3-seeded fleshy bag. Seeds obovate, sur- rounded by a tenacious jelly. 4. RICHARDIA. Leaves arrow-shaped ; these and the long scape from a short tuberous rootstock. Spathe broad, spreading above, convolute at base around the slender cylindrical spadix, which is densely covered above with yellow anthers, below with ovaries, each incompletely 3-celled, and containing several hanging ovules. Flowers with no envelopes. [ I Spalhe shell-form or hooded, inclosing the globular spadix, in ichich the flowers are as it were nearly immersed. 5. SYMPLOCARPUS. Leaves ovate, very large and veiny, short-petioled, appearing much later than the flowers from a fibrous-rooted conn or short rootstock. Spathe ovate, incurved, thick, barely raised out of the ground. Each flower has 4 hooded sepals, 4 stamens with 2-celled anthers turned outwards, and a 1-celled, 1-ovuled ovary tipped with a short awl-shaped style ; the fruit is the enlarged spongy spadix under the rough surface of which are imbedded large fleshy seeds. 1 1 1 Spathe open and spreading (not rolling around the spadix). 6.

Flowers inclosed or subtended by glumes or husk-like bracts ; no proper calyx or corolla, except sometimes mi- nute bristles or scales which represent the perianth. Stems of the straw-like sort, called culms. CXXXIIL CYPERACKE, SEDGE FAMILY. Some rush-like, others grass-like plants, with flowers in spikes or heads, one in the axil of each glume, the glume being a scale-like or husk-like bract. No calyx nor corolla, except some vestiges in the form of bristles or occasionally scales, or a sac which imitates a perianth; the 1-celled 1- ovuled ovary in fruit an akene. Divisions of the style 2 when the akene is flattish or lenticular, or 3, when it is usually tri- angular. Leaves, when present, very commonly 3-ranked, and their sheath a closed tube ; the stem not hollow. A large family, to be studied in the Manual, and too difficult for the beginner. The most prominent genera are the following: * Flowers commonly all perfect. *- Spikelets usually many-flowered with only one or two of the lower scales without flowers. - Scales 2-ranked, the spikelet therefore flat. = No bristles about the akene, and no beak at its top. 1. CYPERUS. Spikelets few-many-flowered, mostly flat and slender, in simple or compound terminal umbels or heads. Culms mostly tri- angular and simple, most of the leaves at the base. Many species in low grounds ; three should be mentioned here : C. rotiindus, Linn. NOT GRASS, Coco GRASS. A bad weed in sandy lands from L. I.,S. ; early leaves grass-like and tufted, 3'-6' high, followed later in the season by a single, leafless, triangular culm, 6'-20' high ; umbel simple or slightly compound, about equaling its involucral leaves, its rays few, and each one bearing 4-9 dark-chestnut, 12-40-flowered, acute spikelets ; scales nerveless. The plant is introduced in the N. It persists in the soil by means of little, nut-like tubers which are borne from several inches to 4 away from the base of plant, on stolons. C. escule'ntuB, Linn. CHUFA. Cultivated, especially at the S., for its edible tubers, which are clustered about the base of the plant, and also wild ; early leaves 15'-30' high, slightly rough, about as long as the stem ; umbel 4-7-rayed, sometimes compound, much shorter than the involucrai leaves ; spikelets numerous and light colored, 12-30-flowered, the scales nerved. The cultivated form rarely flowers in the N. GRAY'S F. F. & G. BOX. 30 466 SEDGE FAMILY. C. alternifblius, Linn. UMBRELLA PLANT. A greenhouse aquatic from Madagascar ; culms in clumps, 2-6 tall, smooth and triangular, leafless below, but bearing a leafy, many-rayed, great involucre at the top, from the axils of which spring slender-peduncled small clusters of flowers. C. Papyrus, Linn. (PAPYRUS ANTIQU&RUM). EGYPTIAN PAPER PLANT. Sometimes grown in aquaria, not hardy N. ; sends up a jointless triangular stem 4-10 high, which is terminated by a great involucre of very narrow drooping or bending leaves. = = Bristles about the akene, which is beaked on top. 2. DULICHIUM. Spikelets 6-10-flowered, sessile in 2 ranks on axil- lary peduncles springing from the sheaths of the leaves. Perianth com- posed of 6-9 barbed bristles. One species, D. spathaceum, Pers., in bogs and on borders of ponds, remarkable in the family for having terete and hollow culms, l-2 high. -M. -w Scales not 2-ranked, the spikelet therefore terete. = Bristles ; culm leafy. 3. FIMBRISTYLIS. Spikelets umbelled, the involucral leaves 2-3. Small plants of either low or dry grounds, of about a half dozen species in our territory. = = Bristles generally present ; culm leafy or naked. II Style somewhat thickened or bulbous at the base, and persistent upon the top of the akene. 4. ELEOCHARIS. Spike one, and without involucre, terminating a slender, simple, leafless culm. Many species (mostly small) in moist grounds and borders of ponds. || || Style not swollen at the base, deciduous. 5. SCIRPUS. Spikelets generally clustered in a compound umbel. Bristles (sometimes 0) barbed. Mostly tall, rush-like, leafy, common plants, but in some species the stems are slender and leafless, and the spike is single and terminal, thus approaching Eleocharis, but the invo- lucre is present in the form of a scale or small leaf. This genus now includes ISOLEPIS, to which the slender species with a solitary terminal spike, leafless and jointless culms, have been referred. 6. ERIOFHORUM. Like Scirpus, but the bristles not barbed and often becoming silky and long exserted in fruit. A few plants in bogs, mostly distinguished when mature by the white, or rusty, woolly heads. t- -- Spikelets only l-2-flowered, and 2 or many of the lower scales flower- less. 7. RHYNCHOSPORA. Spikelets flattish, clustered, or panicled, often whitish or rusty in color. Bristles usually surrounding the beaked or tubercle-topped akene. A score of critical species, mostly small and slender plants, in bogs. 8. CLADITJM. Spikelets terete. Akene not tubercled, and no bris ties. A single species, C. mariscoldes, Torr., l-2 high, in wet places, with small, rusty cymes of capitate spikelets. GRASS FAMILY. 467 * * Flowers unisexual (plants monoecious or dioecious"). 9. SCLERIA. Monoecious. No bristles, and the bony or crustaceous akene naked. About a score of small plants known as NUT RUSH. 10. CAREX. Monoecious or dioecious. Ordinarily no bristles, but the lenticular or triangular akene inclosed in a sac or perigynium. A vast genus, comprising over 200 species in our region, much too difficult for the beginner. Common in all lo*w grounds and in open woods. CXXXTV. GRAMINKE, GKASS FAMILY. Grasses, known from other glumaceous plants by their 2- ranked leaves having open sheaths, the jointed stems com- monly, but not always hollow, and the glumes in pairs, viz. a pair to each spikelet even when it consists of a single flower (these called glumes proper), then a succeeding pair (flowering glumes), rarely one of them wanting, these each inclosing a thinner scale or palet. Flower, when perfect, as it more com- monly is, consisting of 3 stamens (rarely 1, 2, or 6), and a pistil, with 2 styles or a 2-cleft style, and 2 either hairy or plumose-branched stigmas; ovary 1-celled, 1-ovuled, becoming a caryopsis (the thin pericarp adnate to the seed and seeming to be an integral part of it) ; the floury part is the albumen of the seed, outside of which lies the embryo (Lessons, Figs. 66-70). The real structure and arrangement of the flowers and spike- lets of Grasses are too difficult and recondite for a beginner. For their study the Manual must be used ; in which the gen- era both of this and the Sedge Family are illustrated by plates. Here is offered merely a short way of reaching the names of the commonest or most conspicuous species. I. CEREAL GRAINS, cultivated for the seed-like fruits. (II., p. 468; III., p. 469 ; IV., p. 470 ; V., p. 471 ; VI., p. 473 ; VII. , p. 475). * Stems hollow, or soon becoming so, making straw when cut. - Spikelets in panicles, often crowded, but not so as to form a spike. Oryza saflva, Linn. RICE. Cult. S., from Asia, in low grounds ; 2-4 high, with upper surface of the lance-linear leaves rough ; flowers one and perfect in each spikelet, with or without rudiments of others ; branches of the panicle erect ; outer glumes minute, the inner coriaceous, very much flattened laterally, so as to be strongly boat-shaped or conduplicate, clos- ing over the grain and falling with it, the outer one commonly bearing an awn ; stamens 6. 468 GRASS FAMILY. Kvena saflva, Linn. COMMON OAT. From Old World ; soft and smooth, with a loose panicle of large, drooping spikelets, the palets investing the grain ; one flower with a long, twisted awn on the back, the other awn- less ; flowers 2 or 3 in the spikelet, perfect, or the uppermost rudimen- A. ndda, Linn. NAKED OAT. Rarely cult., from Old World; has nar- rower, roughish leaves, 3 or 4 flowers in the spikelet, and grain loose in the palets. - +- Spikelets in strict spikes, or in such a dense panicle as to appear to be spicate. M- Glumes 2 to each spikelet. Trlticum sativum, Lam. WHEAT. Spike dense, somewhat 4-sided; the spikelets crowded, 4-5-flowered, turgid; glumes ventricose, blunt; palet either awned or awnless ; grain free. Unknown wild. Secale ceredle, Linn. RYE. Tall ; spike as in wheat ; spikelets with only 2 perfect flowers ; glumes a little distant, bristly towards the base ; lower palet ventricose, long awned; grain brown. Probably from W. Asia. H- -w Glumes 6 at each joint, in front of the 3 spikelets, forming an involucre. Hdrdeum satlvum, Jessen. COMMON BARLEY. From the Old World ; spike dense, the 3 spikelets at each joint of the rhachis all with a fertile flower, its lower palet long-awned. Originally from W. Asia. H. distichon, Linn. TWO-ROWED BARLEY. From Tartary ; evidently a cultivated state of the above ; only one spikelet at each joint of the rhachis with a fertile flower, the two lateral spikelets being reduced to sterile rudiments ; the flowers therefore two-rowed in the spike. H. hex&stichon, Linn. SIX-ROWED BARLEY. Another form of H. sativum, with roundish spikes, its joints very short and the flowers diver- gently 6-rowed. Not common. * * Stems pithy and thick, not becoming hollow. Z&a Mays, Linn. MAIZE, INDIAN CORN. Stem terminated by the clus- tered, slender spikes of staminate flowers (the tassel) in 2-flowered spike- lets ; the pistillate flowers in a dense and many-rowed spike borne on a short axillary branch (the ear), two flowers within each pair of glumes, but the lower one neutral, the upper pistillate, with an extremely long style, the silk. Very many forms. Cent, and S. Amer. (Lessons, Figs. 66-70.) II. CANES AND SORGHUMS, with pithy, solid stems. Cultivated for sugar or broom-making (occasionally for fodder). Spikelets clustered or scattered in an ample panicle, each with one perfect and one neutral or staminate flower. Sdrghum vulgare, Pers. (ANDROPOGON SORGHUM of some writers).

Cone woody ; the shield-shaped scales closed without overlapping, and bearing 8-6 flat wing-margined seeds hanging from the upper par'', of their stalk-like b*se. 478 PINE FAMILY. ++++++ Leaves evergreen, opposite, awl-shaped and scale- shaped (the former on the more vigorous lengthening shoots, the latter closely imbricated and decussate on the succeeding branchlets), commonly with a resinous gland on the back. Seeds and ovules erect ; cotyledons only 2 or 3. 11. CUPEESSUS. Cones spherical ; the shield-shaped scales closing by their well-fitted margins, not overlapping, separating at maturity, each scale bearing many ovules and narrowly-winged seeds, its broad summit with a central boss or short point. 12. CHAM^ECYPAEIS. Cone globose, terminal, firmly closed, but opening at maturity, the scales peltate. Sterile flowers composed of shield-shaped, scale-like filaments bearing 2-4 anther cells. Leaves small and scale-like, appressed or spreading. Seeds 2-3 below each scale, in which it differs chiefly from Cupressus. 13. THUJA. Cones oblong or globular, the scales not shield-shaped, but concave and fixed by their base, overlapping in pairs, pointed if at all from or near their summit, spreading open at maturity, each bearing a single pair of ovules and winged seeds. (Lessons, Figs. 338, 389.) +- +- Fruit berry-like ; flowers commonly dioecious. 14. JUNIPEKUS. Catkins very small, lateral ; the fertile catkin of 3-6 fleshy' scales grow- ing together, and ripening into a sort of globular berry, containing 1-3 bony seeds. Leaves evergreen, opposite or whorled. III. YEW SUBFAMILY. Distinguished by having the fertile catkin, if it may be so called, reduced to a single, ter- minal flower, consisting of an ovule only, surrounded by some bracts or a fleshy disk, ripening into a nut-like or drupe-like seed ; cotyledons only 2. There is nothing answering to the scales of a pine cone. Leaf buds scaly as in the true Pine Family. Flowers mostly dioecious, axillary. 15. TAXUS. Leaves linear, appearing more or less 2-ranked, green both sides. Both kinds of catkins, if such they may be called, are small axillary buds imbricated with per- sistent scales, bearing at the apex, one a few naked stamens each with 3-8 anther cells under a somewhat shield-shaped apex, the other an ovate ovule. This in fruit becomes a nut-like blackish seed, resting in the bottom of a berry-like red cup. 16. TOEREYA. Leaves, catkins, etc., nearly as in Taxus. Stamens more scale-shaped at top, each bearing 4 hanging anther cells. Xaked seed resembling a thin-fleshed drupe or when dry a nut, with no cup around it, as large as a nutmeg, which it resembles also in the brain -like interior structure. 17. GINKGO. Leaves wedge-shaped and fan-shaped, deeply 2-cleft and the lobes wavy- toothed and somewhat cleft at the broad truncate end, traversed with straight simple or forking nerves or veins, like a Fern. Flowers not often seen. Sterile catkins slender and loose. Seed drupe-like, and with a fleshy short cup around its base. 18. PODOCAEPUS. The fleshy seed raised on a sort of stalk. Leaves sometimes much unlike those of other Coniferous trees, being large, linear, lanceolate, or even ovate, and veinless, except the midrib. 1. PINUS, PINE. (The classical Latin name.)

Plants with creeping or ascending rootstocks, or even erect trunks, bearing distinct leaves (fronds) on stalks (or stipes) which are rolled up (circinate) in the bud, and bear commonly 1 The account of the Flowerless Plants In the original edition was prepared by Professor D. C. Eaton of Tale College. FEKN FAMILY. 487 on the under surface or on the edges the simple fructification, consisting of 1-celled spore cases (technically called sporangia) variously grouped in dots, lines, or masses (called sort or fruit dots) and containing but one kind of minute, 1-celled, powdery, numerous spores, which are discharged when the sporangia finally split open. A large family, most abundant in warm and moist regions. [ The divisions of a pinnatiftd frond are properly called segments ; of a pinnate frond, pinnce ; of a 2-3-4-pinnate frond, pinnules or ultimate segments. The stalk of the frond is a stipe ; its continuation through the frond, the rhachis ; its branches, partial or secondary rhachises. A rha- chis bordered by the leafy portion becomes a midrib, tohich may be primary, secondary, etc.~] I. POL YPODIUM SUBFAMILY. Characterized by stalked spore cases, having a vertical, incomplete, many-jointed, elastic ring, which straightens at maturity, breaking open the spore case transversely, and so discharging the spores. Spore cases rarely if ever on very narrow thread-like branches ; the fruit dots often covered by a scale-like involucre (the indusium). 1. No definite fruit dots, but the spore cases in large patches on the under surface of the fertile frond, or entirely covering the under surface ; no indusium. 1. ACEOSTICHUM CHRYSODIUM. Fronds simple or pin nately branched, with retic- ulated veins ; spore cases covering the whole under surface of the frond or of its upper divisions. 2. PLATTOERIUM. Fronds irregularly forking ; veins reticulated ; spore cases in large patches on special portions of the under -surface. 2. Spore cases on the back of the frond, sometimes near the margin, in dots or lines (sort} placed on the veins or at the ends of the veins, but without indusium of any kind. 3. POLTPODITJM. Fronds simple or pinnate, rarely twice pinnate ; veins free or retic- ulated ; fruit dots round or roundish, at the ends of the veins, or at the point where several veins meet (anastomose). Stalk articulated to the rootstock, and leaving a distinct scar when decayed away. (15. PHEGOPTERIS may be sought here.) 4. GYMNOGRAMME CEROPTERIS.

Botanist's Microscope Designed to be used with the Botanical Text- Books published by the American Book Company. This convenient instrument, devised and manufactured first for the use of the students in Harvard University, has given so great satisfaction there, and elsewhere, that we have made arrangements by which we are able to offer it to students in all parts of the country at a very reasonable price. A thousand things about forest, field, or garden afford objects of intense interest for daily study, and a good Micro- scope furnishes the best means for unlocking their secrets. Of this Microscope the late Dr. GRAY said : "I do not think any- thing better can be made for the money." This Microscope is attached to a box, one and a half inches high and less than four inches long, into which it is neatly folded when not in use. The needles are used for dissecting flowers or other objects too small to be otherwise handled for analysis.

Apgar's Trees of the Northern United States Their Study, Description, and Determination. For the use of Schools and Private Students. By AUSTIN C. APGAR. Cloth, I2mo, 224 pages. Copiously Illustrated . . . $1 .00 This work has been prepared as an accessory to the study of Botany, and to assist and encourage teachers in introducing into their classes instruction in Nature Study. The trees of our forests, lawns, yards, orchards, streets, borders and parks afford a most favorable and fruitful field for the purposes of such study. They are real objects of nature, easily accessible, and of such a character as to admit of being studied at all seasons and in all localities. Besides, the subject is one of general and increasing interest, and one that can be taught successfully by those who have had no regular scientific training.

Of the Ames Botanical Laboratory Prepared at the request of the Botanical Department of Harvard University LEAVITT'S OUTLINES OF BOTANY. Cloth, 8vo. 272 pages . $1.00 With Gray's Field, Forest, and Garden Flora, 791 pp. . .1 .80 With Gray's Manual, 1087 pp 2.25 This book has been prepared to meet a specific demand. Many schools, having outgrown the method of teaching botany hitherto prevalent, find the more recent text-books too difficult and comprehensive for practical use in an elementary course. In order, therefore, to adapt this text-book to present requirements, the author has combined with great simplicity and definiteness in presentation, a careful selection and a judicious arrangement of matter. It offers 1. A series of laboratory exercises in the morphology and physiology of phanerogams. 2. Directions for a practical study of typical cryptogams, represent- ing the chief groups from the lowest to the highest. 3. A substantial body of information regarding the forms, activities, and relationships of plants, and supplementing the laboratory studies. The laboratory work is adapted to any equipment, and the instruc- tions for it are placed in divisions by themselves, preceding the related chapters of descriptive text, which follows in the main the order of topics in Gray's Lessons in Botany. Special attention is paid to the ecological aspects of plant life, while at the same time morphology and physiology are fully treated. There are 384 carefully drawn illustrations, many of them entirely new. The appendix contains full descriptions of the necessary laboratory materials, with directions for their use. It also gives helpful sugges- tions for the exercises, addressed primarily to the teacher, and indicating clearly the most effective pedagogical methods. Copies sent, prepaid, on receipt of price. American Book Company New York Cincinnati Chicago (174) Birds of the United States A Manual for the Identification of Species East of the Rocky Mountains By AUSTIN C. APGAR Author of "Trees of the Northern United States," etc. Cloth, I 2mo, 415 pages, with numerous illustrations. Price, $2.00 The object of this book is to encourage the study of Birds by making it a pleasant and easy task. The treat- ment, while thoroughly scientific and accurate, is interest- ing and popular in form and attractive to the reader or student. It covers the following divisions and subjects : PART I. A general description of Birds and an explanation of the technical terms used by ornithologists. PART II. Classification and description of each species with Key. PART III. The study of Birds in the field, with Key for their identification. PART IV. Preparation of Bird specimens. The descriptions of the several species have been pre- pared with great care and present several advantages over those in other books. They are short and so expressed that they may be recalled readily while looking at the bird. They are thus especially adapted for field use. The illustrations were drawn especially for this work. Their number, scientific accuracy, and careful execution add much to the value and interest of the book. The general Key to Land and Water Birds and a very full index make the book convenient and serviceable both for the study and for field work.

By F. W. CLARKE Chief Chemist of the United States Geological Survey and L. M. DENNIS Professor of Inorganic and Analytical Chemistry in Cornell University THE study of chemistry, apart from its scientific and detailed applications, is a training in the interpretation of evidence, and herein lies one of its chief merits as an instrument of education. The authors of this Elementary Chemistry have had this idea constantly in mind: theory and practice, thought and application, are logically kept together, and each generalization follows the evidence upon which it rests. The application of the science to human affairs, and its utility in modern life, are given their proper treatment. The Laboratory Manual contains directions for experi- ments illustrating all the points taken up, and prepared with reference to the recommendations of the Committee of Ten and the College Entrance Examination Board. Each alter- nate page is left blank for recording the details of the experi- ment, and for writing answers to suggestive questions which are introduced in connection with the work. The books reflect the combined knowledge and experi- ence of their distinguished authors, and are equally suited to the needs both of those students who intend to take a more advanced course in chemical training, and of those who have no thought of pursuing the study further. AMERICAN BOOK COMPANY Publishers NEW YORK CINCINNATI CHICAGO A New Astronomy DAVID P. TODD, M.A., Ph.D. Professor of Astronomy and Director of the Observatory, Amherst College. Cloth, i2mo, 480 pages. Illustrated - - Price, $1.30 This book is designed for classes pursuing the study in High Schools, Academies, and Colleges. The author's long experience as a director in astronomical observatories and in teaching the subject has given him unusual qualifi- cations and advantages for preparing an ideal text-book. The noteworthy feature which distinguishes this from other text-books on Astronomy is the practical way in which the subjects treated are enforced by laboratory experiments and methods. In this the author follows the principle that Astronomy is preeminently a science of observation and should be so taught. By placing more importance on the physical than on the mathematical facts of Astronomy the author has made every page of the book deeply interesting to the student and the general reader. The treatment of the planets and other heavenly bodies and of the law of universal gravita- tion is unusually full, clear, and illuminative. The mar- velous discoveries of Astronomy in recent years, and the latest advances in methods of teaching the science, are all represented. The illustrations are an important feature of the book. Many of them are so ingeniously devised that they explain at a .glance what pages of mere description could not make clear.

DANA, LL.D. Late Professor of Geology and Mineralogy in Yale University. DANA'S GEOLOGICAL STORY BRIEFLY TOLD . . . $1.15 A new and revised edition of this popular text-book for beginners in the study, and for the general reader. The book has been entirely rewritten, and improved by the addition of many new illustrations and interesting descriptions of the latest phases and discoveries of the science. In contents and dress it is an attractive volume, well suited for its use. DANA'S REVISED TEXT-BOOK OF GEOLOGY . . . $1.40 Fifth Edition, Revised and Enlarged. Edited by WILLIAM NORTH RICE, Ph.D., LL.D., Professor of Geology in Wesleyan University. This is the standard text-book in geology for high school and elementary college work. While the general and distinctive features of the former work have been preserved, the book has been thoroughly revised, enlarged, and improved. As now published, it combines the results of the life experience and observation of its distinguished author with the latest discoveries and researches in the science. DANA'S MANUAL OF GEOLOGY $5.00 Fourth Revised Edition. This great work is a complete thesaurus of the principles, methods, and details of the science of geology in its varied branches, including the formation and metamorphism of rocks, physiography, orogeny, and epeirogeny, biologic evolution, and paleon- tology. It is not only a text-book for the college student but a hand- book for the professional geologist. The book was first issued in 1862, a second edition was published in 1874, an d a third in 1880. Later investigations and developments in the science, especially in the geology of North America, led to the last revision of the work, which was most thorough and complete. This last revision, making the work substantially a new book, was performed almost exclusively by Dr. Dana himself, and may justly be regarded as the crowning work of his life. Copies of any of Dana's Geologies will be sent, prepaid, to any address on receipt of the price.

AMERICAN BOOK COMPANY Publishers of School and College Text-Books NEW YORK CINCINNATI CHICAGO BOSTON ATLANTA DALLAS SAN FRANCISCO (3") FOR THE STUDY OF METEOROLOGY Waldo's Elementary Meteorology, $1.50 BY FRANK WALDO, PH.D. Late Junior Professor in the United States Signal Service THIS book embodies the latest phases of the science, and applies the most approved methods in teaching them. The treatment, as far as practicable, is inductive. The style is simple, concise, and clear. The fact that meteorology is largely an observational study is kept constantly in mind. The student is introduced to rational methods of investigation and taught to observe weather conditions, to account intelligently for successive changes in the same, and to make intelligent predictions for himself. Special chapters are devoted to the meteorology of the United States, in which the work of the Weather Bureau is clearly explained. The charts and illus- trations are an important feature. Price's Observations and Exercises on the Weather $0.30 BY JAMES A. PRICE, A. M. Instructor in Physiography in Fort Wayne High School, Fort Wayne, Ind. THIS laboratory manual is intended to supplement the reci- tation work in physical geography and meteorology in sec- ondary schools. It consists of a blank weather record covering forty days, to be filled in by the pupil for his own observations of the thermometer, barometer, hygrometer, weather gauge, clouds, winds, etc. Following these tables is a series of ingeniously devised exercises whereby the pupil, from the observation and study of his weather record, is led to deduce many of the general principles of meteorology. The instruments necessary for the observations are few and inexpensive.
