r\r\r\t-\ M ^ IV INTRODUCTION. One must not look for more than the author proposes to give. Consequently, when the student has become familiar with the structure or morphological details of flowers by which they may be distinguished, he must proceed to the task of unravelling the mystery of their forms; and that is the methods of fertilization, which afford the clue to the various structures ; as. all flowers are adapted either to Self-fertilization, Wind-fertilization r or Insect-fertilization. The literature on this branch of botanical knowledge is very extensive ; and the reader will, no doubt, find access to such works as Darwin's Fertilization of Orchids, Forms of Flowers, c., as well as H. Miiller's Fertilization of Flowers, and the present writer's Origin of Floral Structures by Insect and other Agencies. The study of this branch of physiology will be found to add very materially to the interest of the student, as it is always desirable, if possible, to know the " why " and the " wherefore " of any facts with which we may be familiar. To explain this a little more fully, we may take, for example, the family Ranunculacese, the first in classification and with which the beginner will probably be first acquainted. A Buttercup has a flower with the petals widely spreading ; so that it has been observed to be visited by more than sixty species of insects. Hence the pistils of the flowers on any plant can be easily fertilized by the pollen derived from those of another plant. It is thus adapted to insects and can be " crossed." It may consequently be called an insect-fertilized flower. As, however, the stigmas are mature simultaneously with the anthers of at least some of its stamens, it can easily be self- fertilized in the absence of insect visitors. On the other hand the Aconite with its great hooded sepal has only two petals, and these are connected with honey-secreting " nectaries " concealed within the hood. Consequently it is by no means so easy of access, and only a few kinds of humble-bee can properly extract the honey and " pollinate " the flower at the same time. Moreover, as the stigma is late in maturing, it does INTRODUCTION. V not readily, even if it be at all able to, set seed on its own account, that is by self-fertilization. As an example of complete self-fertilization we may take the Celery-leaved Ranunculus or J?. sceleratus. This species has minute blossoms, easily overlooked by insects. It seeds abun- dantly and is widely dispersed. When we compare the rarity or commonness of plants for setting seed is the only use of flowers to plants the rule is that self- and wind-fertilized plants are by far the most abundant and wide-spread, while those which have become so modified that the flowers actually exclude all but a few kinds of insects, are greatly restricted in their distribution. The above is but a sample, as a hint to the beginner to see what a wide field of observation is before him if he will but persevere and follow it out ; for cceteris paribus, every family furnishes material for similar observations. In conclusion I can but hope the present work will prove as useful as it ought to be, and help the beginner over the initial but often troublesome stage of finding out the name of a plant and where to locate it in the Vegetable Kingdom. Having done this his real work begins, and that is to study his plant in all its stages till he can find out nothing new about it. CONTENTS. PAGE i LOCAL NAMES . . i ii. CLASSIFICATION 16 in.

Against them are set the names under which the flowers are described in this book, which were given them to allow of their identification by the educated people of all nations, and which are just as easy to remember, and in most cases no more difficult to pronounce than the others. The identification of plants by their local names alone is almost impossible, for in the first place the nomenclature is not systematic, and gives no hint as to grouping, and in the second place, as will be seen from this list, in many cases very different plants have the same name, and in other cases many different names are borne by the same plant. 5*3 Aaron's Beard, Hypericum calycimm.

CLASSIFICATION, W ] rE wish to have a nodding acquaintance with the wild flowers we meet with, to be improved into intimacy if we think fit. Not a wish to be ashamed of, surely ! How many of us are there who would find the world more interesting if we only knew the names of the flowers of the field, and the stars of the sky, and gave a thought to the things around us ? How many but let us to work, and moralise after- wards. Here is a plant dug up by the ditcher and thrown on the footpath. What is its name ? The plant is common enough, but we have never troubled to ascertain how it is distinguished from its fellows. Let us do so now. Here it is, root and all. Let us describe it not too technically, but just technically enough. There is first its fibrous root. From the root 521 rises the stem. The stem is slender, and is lightly clothed with hairs. It is simple ; had it been branched at all it would have been compound ; had the branches been two in number and fairly equal in length, it would have been forked. It is perpen- dicular or erect. Had it been horizontal when it left the root and then turned upward it would have been ascending ; had it trailed along the ground it would have been prostrate ; had it sent out roots from its joints as it trailed it would have been creeping, From the stem spring the leaf-stalks or petioles, and these bear the deeply divided leaves. Had the leaves been directly joined on to the stem they would have been sessile. Deeply cut as the leaves are, they are not quite split into separate leaflets, and so they are simple ; had they been completely separated they would have been compound, and then if they had three leaflets on a stalk they would be ternate, if five leaflets quinate, if more than S.VQ pinnate or feather-like. The divisions of the simple leaf are termed lobes, and the lobes here are uneven in number. There is one at the point and one or two or three on each side. When the lobes are narrow, and five or more in number, the leaf is palmate ; when they are cut back equally down the midrib it is pinnatifid. The petiole is attached to the base of the leaf. Had the attachment been at its centre the leaf would have been peltate or buckler- shaped ; had the stem passed through it the leaf would have been perfoliate ; had each pair of leaves been united at their bases they would have been connate. The edge of the leaf is toothed or jagged ; had its outline been unbroken it would have been entire. From the stem there also springs the flower stalk or peduncle, and th peduncle in this case is smooth and cylindrical. CLASSIFICATION. IJ The blossom consists of three rings. First we have a ring of small green leaves. These are the sepals, five in number ; the ring they form is the calyx or cup. The next ring is the bright yellow one of five delicate leaves. These are the petals, and the ring is called the corolla or little crown. Each petal tapers to a point ; the broad part is the limb, the pointed part the claw. At the claw or base is a small scale covering the nectary, and in the nectary is a drop of honey. The petals are separate one from the other. Had they been united the broad part would have coalesced into the border, the claws into the tube. Having stripped off calyx and corolla, which together form the perianth, we come to the flower proper the essential parts, or reproductive organs. First we have a ring of hair-like filaments springing from a centre cushion and each bearing its anther. Had there been no filament the anthers would have been sessile. These anthers contain the yellow fertilizing dust called pollen. In the centre we have the female portion of the flower, \hepistilorovary, consisting of several carpels or unripe fruitlets. Each carpel contains a single ovule, and will eventually develope into fruit when the pollen has been deposited upon it. Here are the remains of another bloom, one that has done its work, in which the ovary has been impregnated, the fruit has ripened, and the soft single-seeded carpel has become a hard, beaked, achene. To what order does this plant belong ? But what is an "order"? An order is a group of genera, as a "genus" is a group of species. What is a "species"? Species is the collective term for a group of individuals possessing similar characters which remain constant so long as the conditions of existence remain unchanged. It was Linnaeus to whom we owe the modern system of nomen- clature, in which every species has a particular name compounded of a substantive and an adjective, whereof the former indicates the genus and the latter the species. In his day Latin was the general language of science ; in Latin his names were given ; and in Latin it is best they should remain until the English tongue has become universal, or the same plant is known by the same name in all English-speaking lands. In order to avoid a difficulty in distinguish- ing between generic and specific names, we have throughout in this book spelt the specific names without a capital letter. For the employment of the capital in proper adjectives there never was an excuse, the practice having been gradually adopted in ignorance of classical usages ; but in the case of the few genitives we are fully aware that the convenience of the student is our only defence. By systematic botanists the characters of the genera are chiefly based on the forms of the flowers and fruit, while the characters of the species are furnished by all parts of the plant. But as our object is not a complete treatise on botany dealing with all the genera of the two hundred and odd orders into which the flowering plants of the world are divided, but merely to help the ordinary wayfarer to recognise his native flowers, without leading him away from the beaten track, we have confined ourselves to a series of diagnoses in which we have chosen whatever portion of the plant affords the readiest means of identification; and we have used stems, leaves c 1 8 CLASSIFICATION. flowers and fruit indiscriminately, so long as they are sufficient to clearly distinguish between either species and species, genus and genus, or even order and order. For the proper identification of a plant it is important that it should be in flower and fruit in fact, that it should be complete in all its parts ; and as all plants have not the convenient habit of being in full leafage and in flower and fruit all at the same time, it would be necessary that several specimens should be procured in different stages of growth, were not some such general characters as are herein given ordinarily enough for determination. It will be noted, however, that it is with our country's flowers, and not our country's plants, that we profess to deal ; and that, after all, is the natural way, as the only true basis of classification in the organic world must be the organs of reproduction. A few of the Linnsean descriptive terms, referring to these organs, may here be recalled to the reader's recollection. When the stamens and pistils are combined in the same flower, the flower is said to be perfect; when they are in different flowers on the same plant, the plant is said to be monoecious j when they are in different flowers on different plants, the plant is said to be diceciotts. When the stamens and pistil are united in a column, the flower is gynandrous; when the stamens are united by their anthers, the anthers are said to be syngenesious ; when they are united by the filaments in more than two bundles, they are polyadelphous j when they are united in two bundles, they are diadelphous; when they are united in a single bundle, they are monadelphous ; when they are of different lengths, with four long and two short, they are tetradynamous ; when there are two long and two short, they are didynamous. It was chiefly by the stamens that Linnaeus sorted out the plants, and although his system is now obsolete, the stamens are still of prime importance in the classifica- tion of genera. But in species, as we have said, all parts of the plant can be drawn upon for characteristics. Specific names are generally adjectives ; generic names are in- variably substantives ; while in the names of the natural orders we again revert to the adjectival form. Take the Rosa canina for instance : in canina we have the adjective agreeing in gender with the substantive, and out of the substantive we form the adjective Rosacece, the substantive Planttz being understood, the intention being to describe the order as containing the Rosaceous Plants. The orders are, in general botany, grouped into Sub-cohorts, Cohorts, Sub-classes, and Classes ; but with us this elaborate grouping can be simplified, in words if not in fact, and we can content our- selves with stepping direct from Orders to Classes, and thence to Divisions. The- Vegetable Kingdom then, is divided into plants that flower, and plants that do not flower, but reproduce themselves by means of spores. Any given plant must consequently be either Phanerogam Greek, phaneros, evident ; from the mode of re- production being unconcealed, or, Cryptogam Greek, cruptos, hidden ; from the mode of pro- duction being concealed. CLASSIFICATION. 19 If our plant be a Cryptogam, it may be either a Cormophyte, that is one provided with stems, leaves and roots, or their morphological equivalents, or it may not. If it is not so provided, it may be either one of the Algae, the Fungi, or the Protophytes the three classes of the Thallophyta, as such cryptogamic plants are called as have a mere thallus with no special ascending or descending axis, and no contrast of axis and appendages but to have included these classes in our book would have made it too large and unwieldy. And for the same reason we have not included the Mosses and Liverworts which form the second class of the Cormophytes, with the first class of which we begin our identifications. This first class is the Vascularia. To it belong four orders, those of the Ferns, the Lycopods, the Pillworts, and the Horsetails. These are so few that we can dismiss them at once after a very casual glance. 1. Filices the Ferns leafy plants of varied structure with the fructification of seeds or sporules which are included in cap- sules, thecas or sporangia. These are either naked or covered with a membrane, and are generally collected into clusters on the edge or underside of the leaves. 2. Lycopodiaceae the Club Mosses leafy plants with the fructifi- cation in the axils of the leaves or in the bracts of a cone. 3. Marsileaces: the Pillworts plants with slender circinate leaves, with the spores in globular masses, and invested by hardened mucilage. 4. EquisetaceiE the Horsetails herbaceous plants with jointed, furrowed, hollow stems, and whorls of scale-like leaves at the joints. These four orders are so unlike in their British representatives that the distinction between them is easy. And we can profitably devote the rest of our space to the consideration of our flowering plants such as our specimen. If our plant is not a Cryptogam, it must be a Phanerogam. Now, the Phanerogams are divided into two classes : 1. Dicotyledons (plants with two seed leaves). 2. Monocotyledons (plants with one seed leaf) all Cryptogamous plants being necessarily Acotyledonous. This division of plants in accordance with the number of seed leaves is, like all classifications, purely arbitrary. It should never be forgotten that classification is but an aid to memory, and that " natural groups have nuclei but no outlines." Man classifies not Nature. Man has his " kingdoms," and " divisions," and " classes," and " orders," and " species," not Nature. Nature has no pigeon- holes ; her works stand side by side, each growing out of the other, each overlapping the other ; and hard and fast lines and gaps and slips exist only in man's ignorance. In nearly all systems of classification there are inevitable over- lappings. Even among such a broad group as the Dicotyledons, we shall find a few plants with no cotyledons at all, or with one cotyledon, or with more than two cotyledons ; and so with the other distinctive marks of the class. The statement is disheartening, but it is as well C 2 20 CLASSIFICATION. to make it at the outset to avoid misconception. Practically, there is no trouble in sorting out flowering plants into their proper class ; for the sorting is done not on any one character, but on the pre- ponderance of many characters which are held to be more or less distinctive. It is essential, then, that we give the full definition of our two great classes ; and we cannot do better than quote them from Henfrey. Class I. Dicotyledones Flowering Plants, with stems (when woody) having pith and bark separated by a compact layer of wood, which, in perennial plants, receives annual additions on the outside, beneath the bark ; leaves with the ribs mostly distributed in a netted pattern and generally diminishing in size as they branch ; parts of the floral circles mostly five or four, or some multiple of those numbers, rarely three ; embryo with a pair of cotyledons, and a radicle or primary stem, from the apex of which is developed the primary or tap root. Class II. Monocotyledones Flowering Plants, with stems in which the woody bundles are isolated and diffused through a paren- chyma in which there is no distinction of pith and bar]c, the indi- vidual woody bundles rarely being developed further after the fall of the leaves to which they belong ; the leaves (very commonly sheathing at the base) generally with a number of nearly parallel, straight or curved ribs, or with similar ribs given off from a mid-rib ; the cross veins suddenly smaller, occasionally netted-veined ; the flowers generally with three organs in each whorl ; the floral envelopes often all petaloid, or all green or scale-like, rarely with a green calyx and coloured corolla ; seed with an embryo with one cotyledon only. After due consideration of these carefully-worded definitions of the two great classes, we can resume the identification of our British plant. If it be a Monocotyledon, it can be assigned either to 1. Petaloidae plants with a perianth ; or, 2. Glumiferae plants without a perianth, but with glumes. If it be one of the Glumiferas, it must belong either to 1. Cyperacese the galingale or sedge order having solid stems often angular, and frequently without joints, and leaves with entire sheaths ; or, 2. Gramineae the grass order having jointed hollow stems and leaves with split sheaths. There is no need for further detail. If it cannot be assigned to one of these orders, it must be a petaloid. Of the petaloidae there are fifteen orders represented in Britain. Of these five have the ovary inferior, that is below the base of the outer flower circle or perianth, and the rest have it above that base. The five have also the ovary adherent to the perianth tube, while the ten have it free. The five are : Orchidaceae the orchids. Iridacere the flags. Amaryllidaceae the daffodils. Hydrocharidaceas the frog bits. Dioscoreaceas the black bryony. The last we can deal with at once. It is impossible to mistake its one representative. It is a climbing plant. It has netted-veined, CLASSIFICATION. 21 bronzed leaves, alternate, broad, heartshaped and stalked. The flowers are small and have bracts, and the stamens and pistils are in separate flowers. The order has but one British genus, and that genus has but one species, the well-known black bryony. The four are not so easily dismissed. Their leaves are all parallel veined like those of the bulk of the plants among the Monocotyledons, and they all, as we have seen, have the ovary inferior. Let us take the last first. Hydrocharidaceas. Water plants with the leaves floating or sub- merged, radical, that is, at the base of the flowering stem, and will, serrated margins. Flowers conspicuous and unisexual, and with a spathe. Stamens 3 or 6 free from the style. We have three left, all with bi-sexual flowers. Orchidaceae. Stamens three, two of which are abortive, so that with one exception (Cypripedium) the British genera have but one perfect anther. Stamens and style united. Iridaceae. Stamens three, none of them abortive. Stamens free from style. Amaryllidaceae. Stamens six, free from style. These three orders are distinguishable by the stamens alone. There 'are other differences, of course, but we need not give them here. We have now to deal with the petaloids having the ovary above the base of the perianth. Of these there are incur country the repre- sentatives of ten orders, of which this is the usual arrangement : Liliaceae of which the lily is the type. Triiriareae the herb paris. Melanthaceae the saffron. Alismaceae the water plantain. \ Naiadaceae the pond weed. Lemnaceoe the duckweed. Araceae the lords-and-ladies. Typhaceaa the reed-mace (more popularly called the bulrush, a name transferred to it from another p lant,) Restiaceae the pipe wort. Jiincaceas the rush.. . . Four of these we can sort out at once as having their leaves more or less obscurely net-Veined. These are Trilliaceoe. Lemnaceae. Alismaceae. Araceae. The Trilliaceae are represented by but one genus and one species in our flora. The plant is unmistakable. It is Paris quadrifolia. Its flowers are terminal and solitary, and just below them is a whorl of four ovate leaves. The Alismaceae have a perianth ; the other two orders have none, but one is not likely to be mistaken for the other. The Lemnaceae are small, stemless, free, floating plants with flowers in the axils of the leaves or at the edge of the frond. The Araceae are not floating plants : their leaves sheathe at the baseband their flowers are on a spadix enclosed in a leafy sheath. No one would mistake a duckweed for an acorus or an arum. Our ten are thus reduced to Liliacex. Melanthacese. Naiadacea? Typhaceae. Restiaceae. Juncaceae. 22 CLASSIFICATION The Restiaceae have but one representative, the water plant Erioeaulon septangularc. Though the seven angles may not be very clear, the plant is distinct enough, with its compact scaly head of flowers split up by bracts, and its stem with sheaths slit in the side, without referring to see if the colourless perianth is in two, three, four, five, or six parts, with the two or three stamens adherent to its inner segments. The Juncacece, too, are almost sufficiently familiar. The narrow small round leaves of the rush are known to every child who can identify the order without appealing to the scarious, six-parted perianth, the six or three stamens, and the three stigmas that are sometimes reduced to one. The points in which the other four differ are as follows : Typhaceae Perianth wanting ; stamens many. Naiadaceae Perianth of three or four scales or wanting ; stamens four. Melanthacese Perianth in six. Stamens six. Anthers extrorse, that is, opening outwards. Fruit septicidal. Liliaceae Perianth in six. Stamens six. Anthers introrse, that is, opening inwards. Fruit loculicidal, that is to say, dehiscence takes place through the dorsal sutures so as to open the carpel cavity from behind ; whereas, had it been " septicidal," it would have taken place through the septa so as to isolate the previously com- bined carpels. We have no more monocotyledonous orders to deal with. Our plant is neither a glumifer nor a petaloid ; it must belong to one of the eighty-one orders that represent the dicotyledons in Britain. We can treat these conveniently under three divisions : 1. Polypetalse, in which both calyx and corolla are generally present, and the corolla consists of distinct petals. 2. Monopetalae, in which both calyx and corolla are generally present, and the corolla consists of united petals. 3. Incompletas, in which either the calyx, or the corolla, or both are absent. Let us take the Incompletae first. Of these there are two obvious divisions 1. Plants with both floral envelopes absent; 2. Plants with only one of the floral envelopes absent ; And the first of these can be again obviously divided into 1. Plants with their flowers in catkins ; 2. Plants with their flowers not in catkins. Of these latter there are four orders 1. Empetraeeae represented only by the crowberry. 2. Euphorbiaceae represented by the spurges, the box, and the mercury. 3. Urticaceae represented by the stinging nettle, the pellitory, and the hop. 4. Ulmaceje represented by the elm. The Ulmaceae are separable at once. To say nothing of their being the only trees of the group, they have the only perfect flowers, that is, the stamens and pistils are found tog-ether. Again, the fruit is a samara, that is, it is winged. The stamens are always five. In CLASSIFICATION. 23 Urticaceas the stamens may be four or five, and the flower is either moncecious, dioecious, or polygamous. In Ulmaceae the ovary is two celled ; in Urticaceae it is single celled, and the fruit is not a samara. The EuphorbiacejE are herbs with milky stems, with the anthers and pistils in different flowers on different plants, and often having the flowers wrapped in an involucre. The Empetraceae have but one genus in Britain and one species, which is a small shrub with ever- green alternate leaves, bearing dioecious flowers with three stamens. In fact, the stamens alone will distinguish the four orders. Empetraceae have three stamens. Euphorbiacese have either one stamen or more than eight. Urticaceae have four or five stamens. Ulmaceae have four, five, six, seven, or eight, but oftenest five. From this point of view, the only difficulty is with the last two orders, but the elm tree is never likely to be mistaken for a dusty stinging-nettle, a clinging wall pellitory, or the bold climbing hop. There are five orders having their flowers in catkins. Cupuliferae the oak, beech, hornbeam, and hazel. Betulaceae the alder and the birch. Salicaceae the poplar and the willow. Myricaceae the bog myrtle. Coniferae the fir, the juniper and the yew. Of these the Coniferae are at once distinguishable by their having the male flowers in deciduous catkins, and the female flowers in cones. It is the Conifers which bridge the gap between the flowering plants and the ferns. The Myricaceae have but one genus and one species, and this is a small aromatic shrub, with inconspicuous flowers, having from four to eight stamens. The Betulaceae have from one to four stamens ; the Cupuliferae have from five to twenty stamens ; the Salicacese have from two to thirty stamens, but have no perianth. To summarise Cupuliferae fruit in a cup (the acorn, for instance) ; perianth, five or six-lobed ; stamens five to twenty. Betulaceae fruit not in a cup ; perianth in four or none ; stamens, four ; fruit two seeded. Salicaceae fruit not in a cup ; perianth, none ; stamens, two to thirty ; fruit many seeded. Myricaceae fruit a drupe ; perianth, none ; stamens, four to eight. We have now to take up the plants that have only one of the floral envelopes absent. Of these there are seven orders, two of which have the ovary inferior, the remainder having it superior. Those with the ovary inferior need not detain us long. They are 1. Santalaceae, which have less than six stamens. 2. Aristolochiaceae, which have six or more stamens. The others are Amaranthaceae. Chenopodiaceas. Eleagnaceae. Thymelaceae. Polygonaceee. Amaranthaceas are represented by one species, which has an unjointed stem, and very tiny flowers in axillary clusters. Eleag- nacex are also represented by only one species, which has peculiarly 24 CLASSIFICATION. silvery scales and leaves, and no stipules. The male flowers of this order are in catkins, and it would be placed among the Amentiferce were it not for its other characteristics, which ally it closely with the present group. It is, however, so unmistakable, that it matters very little where it is placed ; it is the only plant in the flora with silvery scales and leaves. Thymelaceae have bi-sexual flowers and eight stamens, the leaves not being stipuled, and the perianth being quickly deciduous. The two chief orders of the group are Cheno- podiaceas, with jointed stems and no stipules to the leaves, and Polygonaceae, having stems as though with a series of knees, with large sheathing stipules to the leaves. The state of affairs is thus : 1. Amaranthaceae no joints, no stipules. 2. Chenopodiaceae joints, no stipules. 3. Polygonaceae joints, large stipules. 4. Eleagnaceae the silvery scales. 5. Thymelaceas the deciduous perianth. We have now run through the Incomplete, and the way is clear for our attack on the great class in which both calyx and corolla are generally present. And first for the Monopetalae, in which the corolla consists of inseparate petals. These can be divided at the outset into 1. Flov/ers with the ovary inferior. 2. Flowers with the ovary superior. And the latter can be divided into 1. Flowers with the stamens on the corolla. 2. Flowers with the stamens free from corolla. The latter has its only representative in the Ericaceae or Heath tribe. The Monopetalous flowers having a superior ovary and stamens on the corolla can be divided into 1. Those having the corolla regular. 2. Those having the corolla irregular. The Monopetalous orders with irregular corollas are : 1. Scrophulariaceae such as the foxglove. 2. Orobanchaceae such as the broom rape. 3. Lentibulariaceae such as the bladderwort. 4. Verbenaceae such as the vervain. 5. Labiatae such as the dead nettle. 6. Plantaginaceae such as the plantain. The Orobanchaceae are distinguishable at once as being scaly, leafless root-parasites with brownish flowers, in which are four stamens, two longer than the rest. The Lentibulariaceas are also unmistakable. They have but two stamens, and the corolla is two-lipped ; a combination not found in any other order. They are small marsh herbs, with the leaves radical and undivided, or else compound and bearing bladders. The Verbenaceae have but one representative, the vervain, which is an erect square-stemmed plant, having opposite three-toothed leaves, a tubular calyx, a tubular two-lipped corolla, on which are two long and two short stamens, the flowers being in long spikes. Our six orders are thus reduced to three. 1. Scrophulariaceae. 3. Plantaginaceae. 2. Labiatae. CLASSIFICATION. 25 The last of these are herbaceous plants of humble growth, with undeveloped stems and tufts of ribbed leaves spreading more or less on the ground. There are four stamens which are very long, alternate with the segments of the corolla, and having very lightly attached anthers, and the tubular corolla is very thin, dry and membraneous. The Labiatae have square stems and opposite aromatic leaves. The flowers are in whorls or cymes. The calyx is tubular and bila- biate, or in five; the corolla is generally bilabiate. The stamens are two or four, half being longer than the others. The carpels are united into a four-celled ovary, with the style rising between the lobes. The Scrophulariaceae contain all the monopetalous flowers with superior ovaries and irregular corollas that do not belong to our five other orders. The main difference between the plants of this order and the Labiates being the absence of the square stem, the two-celled ovary as against the four-lobed one, the terminal style as against the basilar one, and the flowers not being in whorls or cymes. Our next concern is with the monopetalous plants having a superior ovary, stamens on the corolla, and regular flowers. There are ten orders that can be so grouped. Two of these have the stamens opposite the corolla lobes. 1. Primulaceae the primrose tribe. 2. Plumbaginaceas the thrift tribe. The latter of these has a tubular, thin, dry, membraneous calyx, sufficiently distinguishing it from the other orders of the group. We have thus eight orders left in which the stamens are alternate with the corolla lobes. These we can divide into halves, one half having opposite leaves, and the other alternate leaves. Those with opposite leaves are 1. Aquifoliaceae the holly. 2. Oleaceas the privet and the ash. 3. Apocynaceae the periwinkle. 4. Gentianaceas the gentian. The holly is the only representative of the Aquifoliaceae we have. Its spiny leaves and scarlet berries are too well known for us to need to linger over its four or five stamens, and its four or five cleft calyx. The periwinkles, major and minor, are the only representatives we have of the Apocynaceae. They have five stamens, and the corolla and calyx are in four or five, generally five, and shaped like a pen- tagon with bisected sides. The Oleaceas are represented by the privet shrub and the ash tree, each having two stamens in their flowers, though the four-cleft corolla and calyx may not exist. These two stamens are a sufficient distinction for our purpose. The Gentianaceae are smooth herbs with a bitter juice and strongly- ribbed sessile leaves, having calyx, corolla, and stamens all from four to ten, and a capsular fruit. The last four orders of our arbitrary grouping have alternate leaves : 1. Polemoniaceae represented by the Jacob's ladder, 2. Convolvulaceae the waywind. 3. Solanaceac the nightshade. 4. Boraginaceas the borage. 26 CLASSIFICATION. The Convolvulaceae are distinguishable at once by their calyx of five imbricated sepals. The Polemoniaceas have but one representative, the purplish blue Jacob's ladder, a bold regular flower in fives with a three-celled ovary. The Boraginaceas are also in fives, but the ovary is four-celled. The Solanaceas are also in fives, though the stamens number occasionally but four, and the ovary is two-celled. In Solanaceae the flowers are in axillary cymes ; in Boraginaceae they are in spikes ; in Polemonium they are in a panicle. Polemonium, too, has pinnate leaves. A spike is when the flowers are sessile along a single undivided stem. When the flowers are borne on pedicels along such an un- branched rachis, they are said to be in a raceme. When the stem is branched and bears two or more flowers, they are said to be in a 'panicle. When several flowers are gathered into a compact cluster, they are said to be capitate; when the branches or pedicels appear to start from the same point and are nearly of the same length, the flowers are said to be in an umbel ' j when the lower branches are much longer than the upper, so that although starting from different points, they all attain the same level, and the flowers are in a flat head, the flowers are said to be in a corymb. When the flower head is branched, and the flowers open from within outwards in a widening ring, the inflorescence is called a cyme. The inflorescence of a plant is the arrangement of its flowering branches and the flowers upon them ; its cestivation is the arrangement of the sepals or petals in the bud ; its vernation is the arrangement of its leaves in the bud. But we need not overburden ourselves with definitions. We have now the Monopetalous flowers with inferior ovaries. Of these there are seven orders, five of them having the stamens on the corolla, and two having the stamens free of the corolla and on the ovary. These two we will deal with first. They are : 1. Campanulaceae the bell flowers. 2. Vacciniaceae the whortleberries. The first have only five stamens ; the last have eight, nine, or ten stamens, a simple, but for our purposes quite adequate, distinction. We are thus left with the five orders having stamens on the corolla. They are : 1. Caprifoliaceae such as the honeysuckle. 2. Rubiaceae such as the madder. 3. Valerianacea2 such as the valerian. 4. Dipsaceae such as the teasel. 5. Composita? such as the dandelion. In this country the Rubiaceae are represented by herbaceous plants with square stems and whorled leaves, and that distinguishes them at a glance. Of the four orders left, three have four or five stamens ; the fourth, Valerianaceae, have either one or three stamens, and that sufficiently separates them from the rest. The Caprifoliaceae have four or five stamens alternate with the corolla lobes, and the calyx is in four or five, attached to the ovary and having bracts. Their fruit is a berry. They are represented in this country by the elder, the guelder rose, the wayfaring tree, the honeysuckle, and the Linnaea, the characteristics of which will be found fully given in our index of genera. CLASSIFICATION. 27 We are thus left with the Dipsaceae and the Composite. The Dipsaceae have the calyx in four enclosed in an involucel, the corolla in four, with the limb oblique, four stamens on the corolla, free anthers, and inferior ovary with one pendulous ovule. The Compositse have the calyx wanting, or with a membraneous or pappose limb, the corolla funnel-shaped, ligulate or bilabiate, nearly always five stamens, connate anthers, and inferior ovary with one erect ovule. We have now found that our plant belongs neither to the acoty- ledons, the monocotyledons, the incompletae nor the monopetalae. It must therefore belong to the Polypetalae, the most extensive sub- division of the Dicotyledons. This great subdivision comprising all Dicotyledonous plants with free, separate petals, can be split con- veniently enough in two groups. 1. Those having hypogynous stamens. 2. Those having perigynous or epigynous stamens. And the latter can be further divided into 1. Those with the ovary superior. 2. Those with the ovary inferior. The latter of which can be still further grouped 1. Those having four petals or less. 2. Those having five petals or more. 3. Those having four or five petals. The first of these need not detain us long. There are only three orders in the group : one being the Haloragaceae, in which there are no petals at all, and which consist of aquatic herbs like the marestail, &c., in which the leaves are in whorls ; another, the Loranthaceae comprising only the parasitic mistletoe in which the leaves are opposite and fleshy, and the fruit a pulpy white berry ; and the other the important willow-herb order, Onagraceas, in which the calyx is in two or four, tubular, adnate to the ovary and valvate in bud ; the petals are two or four, twisted in aestivation, and the stamens are perigynous and number two, four, or eight. The orders in the group having always five petals are : J. Cucurbitaceae, represented in this country by the white bryony, a climbing herb, with alternate palmate leaves, tendrils, greenish flowers, parts in five, and red berries. 2. Araliacse, represented amongst us by the climbing ivy, and the green cubical flowered moschatel. 3. Umbelliferse, the great order whose umbelled flowers and simple or deeply divided sheathing leaves are so unmistakable, however embarrassing may be its detail in genera and species. There are two orders, having sometimes four, and sometimes five petals. These are Grossulariaceae and Cornaceae. In Grossu- lariaceae the leaves are rough, lobed and alternate ; in the other order they are simple, ovate and opposite. Grossulariaceae are represented with us by the one genus Ribes, of which the black and red currants are the most appreciated species. Cornaceae also have but ona genus, Cornus, the dogwood common in our hedges, and the detailed description of which we can very well reserve till we deal with genera and species. In no way are they likely to be mistaken for the marestail, the mistletoe, the willow herb, the white 28" CLASSIFICATION. bryony, or the ivy, and any doubt that may arise between the Cornacae and Umbelliferas will be set at rest at once by a look at the leaves The polypetalous orders with stamens arranged round or on a superior ovary are 1. Celastraceae such as the spindle tree. 2. Rhamnaceae such as the buckthorn. 3. Leguminosae such as the furze. 4. Rosaceae such as the rose. 5. Lythracese such as the purple loose-strife. 6. Tamariscaceas such as the tamarisk. 7. Portulaceae such as the blinks. 8. Illecebraceas such as the strapwort. 9. Scleranthaceas such as the knawel. 10. Crassulaceae such as the stone-crop. ir. Saxifragaceae such as the London pride. The Leguminosae are distinguishable at once by their papilionaceous corollas. The Rosaceae need no lengthened notice ; their characteristics are so well marked alternate leaves with a stipule on each side of the petiole base, calyx four or five lobed, free or adherent to ovary, petals five, equal, stamens many and curved inwards in aestivation, and fruit never a legume. Obvious enough, too, are the tamarisks. There is but one of them in this country, a straggling coniferous-looking shrub with twiggy branches and scale-like leaves, and flowers small and regular, in lateral spikes, and having all their parts in four or five. Portulaceae;, too, with their single representative, the miserable little blinks, can hardly stop the way, as fortunately the two sepals only mark them off from the rest; and Illecebraceas with their sessile leaves, .and Scleranthaceas with their connate leaves, are also sufficiently recognisable. We. are thus left with Celastraceas stamens four or five, alternate with petals. Rhaninaceab stamens four or five, opposite petals. Lythraceae stamens three or six or twelve, leaves opposite or whorled.. Crassulaceae stamens three to twenty ; thick, fleshy leaves ; flowers symmetrical. . Saxifragaceae stamens five or ten ; styles two, diverging ; flowers unsymmetrical. And now our road is clear for noting the distinctions by which the orders can most easily be sorted out among such of the polypetalous plants as have their stamens rising from beneath the ovary. It will simplify matters to consider five of these orders by themselves. . I. Caryophyllaceae a well marked order, mostly with stems tumid at the joints ; leaves at the joints entire and opposite, flowers regular, sepals four or five, distinct or connected in a tube, petals four or five, clawed, stamens four, five, eight or ten ; anthers opening longitudinally, capsule opening at the top with teeth. The commonest plants of the order are the stitch- worts, pinks, and campions. 2. Aceraceas an order with only one genus,' and that of only two species, one of which is the maple tree, and the other the sycamore tree, sufficient descriptions of which will be found in the index. The stamens number from five to twelve, CLASSIFICATION. 29 3. Droseraceae an order with but one genus, having the, three sundews as its representatives. Its .stamens are either five or ten but further description can be postponed for our index. 4. Elatinaceae an order with only one genus, which is repre- sented by the two waterworks, and for which see the index to the genera. Its stamens may be either three, five, six or ten. 5. Ranunculaceae for the one genus Myosurus, for which see the index to genera. These caryophylls, and acers, the little insectivorous sundew, the tiny water herb, and the eccentric mousetail, are so unlike each other, and so unlike all the other orders we have left to us, that their sorting out in this way will embarrass no one. We have, then, eighteen orders left. ^We can group them most easily into those having BXW *h* teliJFamens and those having less than ten stamens, the four orders we* have just parted with being those in which the number of the stamens would overlap and render such grouping impossible. Polypetalous plants, with stamens hypogynous and less than ten: 1. Berberidaceae three, four, or six stamens; a spiny shrub, the spines being in threes. 2. Fumariaceae six stamens in two bundles ; slender herbs, with brittle stems. 3. Cruciferae six stamens, two shorter than the rest ; herbs with alternate leaves. 4. Violaceas five stamens, the connective produced above the anther cells. 5. Polygalaceae eight stamens in two bundles ; small herbs, with irregular flowers. 6. Frankeniaceae four, five, or six stamens ; a low branched herb with opposite leaves and red flowers. 7. Linacese four or five stamens, alternate with petals, with small teeth between them ; flowers blue or white. 8. Balsaminaceas five stamens ; a succulent herb, with axillary yellow flowers. Here at a glance we have just enough to enable us to place a plant in its proper order, and the other detail we can reserve for our alpha- betical list. Our next group will be Polypetalous plants, with stamens hypo- gynous and atnra thnn ten. or-wxore. 1. Ranunculacece stamens, twelve or more. 2. Nymph aeaceae stamens many, partially petaloid. 3. Papaveraceas stamens many. 4. Resedaceae stamens, ten or more. 5. Cistaceae stamens many. 6. Malvaceae stamens many, united into a tube. 7- Tiliaceae stamens many. etiivt. 8. Hypericaceae stamens many, united into three or four tundles. 9. Geraniaceae stamens ten. 10. Oxalidaceae stamens ten, five longer than the others. Here Nymphaeaceae, the water lily order, Malvaceae, the mallow order, Hypericaceae, the St. John's wort order, and Oxalidaceae, the wood sorrel order, are at once distinguishable from the rest and from CLASSIFICATION. each other. The Resedaceae, the mignonette order, is represented by only one genus, Reseda, which is not likely to be assigned to the Geraniacese, as it has neither the habit, the swollen stem, the clawed petals, nor the beaked fruit, as noted in our index to the genera. Our many-stamened orders are thus reduced to 1. Ranunculaceae. 2. Papaveraceae. 3. Cistaceae. 4. Tiliaceas. Now Tiliaceas has but one genus amongst us, and that is Tilia, to which belong the three species of lime tree. Its leaves are lop- sided, alternate and stipulate; its flowers are regular and greenish; its sepals are four or five, and deciduous ; its petals are four or five ; and, generally speaking, it would be like the Malvaceae, if the stamens were united as in that order. Cistaceae has but one genus amongst us, and that is Helianthemum the rock rose, which is a shrubby herb, never over a foot high, and bearing a white or yellow flower, having five sepals, two smaller than the rest and three twisted in the bud, and five petals crumpled and twisted in the bud the contrary way to the sepals. The rock rose, in fact, is not likely to be mistaken for a lime tree. Papaveraceae is the poppy order. It consists of herbs with white or coloured milky juice, leaves alternate, simple, or lobed, and without stipules ; flowers regular, fugacious, and usually crumpled in aestivation and nodding in bud ; sepals two, or very occasionally three, disappearing early ; petals four, rarely five or six ; and a capsular fruit. We have but one order left, the Ranunculaceae. It comprises land and water herbs and a climbing shrub, all having colourless, acrid juice. Its leaves are generally deeply divided and nearly always alternate, and occasionally they have dilated sheathing petioles. Its flowers are regular or irregular, and of all colours. Its sepals are three, five or six, green or petaloid ; its petals are five or more, free and often irregular ; its stamens are (with the exception of Myosurus) twelve or more, and hypogynous, as we have seen ; and its anthers are adnate and mostly reversed. To the Ranunculaceae our plant belongs. But before we proceed further with its identification it is desirable that we should give in tabular form the classification we have adopted, and which, let it be clearly understood, is only entirely applicable to our country's flowers. 3*3.
