THE present Volume contains all the figures of the dif- ferent species, and the most prominent varieties, that the Author has at present been able to procure : he has, there- fore, brought the work to a conclusion ; which he be- lieves will be more agreeable to the greater part of his Subscribers, than to keep it open for a length of time, to admit others occasionally, as they may be newly in- troduced to the gardens, or as the old species might be sometimes found in obscure collections, where they are little expected to be. A great many interesting species that were plentiful in the nursery collections some years back, are not now to be met with, many of them being sufficiently hardy to endure a favourable Winter without protection, but to be destroyed by a severe one, when the least covering would preserve them ; the correct names of them were also so little known, and one substituted for another so frequently, that caused less attention to be paid to them than they deserved, which we hope will not be the case in future, as a very little protection is sufficient for the whole of them, and nothing produces a more brilliant effect, than a collection of them planted in rock- work, or even grown in small pots, and placed together in a clump, where the different colours may all be intermixed, or kept separate, according to the taste or fancy of the possessor. 602 v ADVERTISEMENT. We are aware that there are still several species in the different collections, that we have not met with in flower ; three or four species in Mr. Anderson's collection, at the Botanic Garden at Chelsea, some others in Mr. Barclay's collection, at Bury-Hill ; those at the Chelsea Botanic Garden have not yet flowered, most probably owing to Pftt 1 the cold wet Summer ; several annual species that We have often raised from seeds several years back, we have not been able to procure since the commencement of the present publication. We have also given a description of the Natural Order and of the published species that we have not been for- tunate enough to meet with ; this should be placed at the beginning of the work, to follow the list of books referred to, which must also follow the title-page. To A. B. Lambert, Esq. we render our grateful ac- knowledgments for allowing us free access to his Li- brary and Herbarium, which has been of great service to us in determining the plants of different authors, many of the original specimens from the authors them- selves being now in Mr. Lambert's collection. To Mr. William Anderson, the worthy Curator of the Chelsea Bo- tanic Garden, we have also to return our best thanks, for his kindness in allowing us to make drawings of several rare species, which we have not met with in any other collection ; and also to the various Nurserymen, for their readiness in assisting us with specimens or plants for drawing and description, from their various establish- ments. . >lfaflA) XJAKlii sdl fl* ssiaaqg JJSIST t BOOKS REFERRED TO.

The present plant was not unfrequent at the Nurseries some years ago, where it was considered a spreading variety of H. algarvense; and, from its habit, was not so much esteemed. We believe it has now quite disappeared from them ; but is most probably still cultivated in some of the gardens in the neighbourhood of Paris. Ventenat's figure was from a plant cultivated in the garden of M. Cels. 3. H. atriplicifblium ( W. enum. 569.)

Native of England? France, Italy, Spain, Portugal, and Turkey ; but is not H. eriocaulon intended for some of the above habitats ? Not having seen a wild specimen of the English plant, we are not certain to which of the two it belongs; the one generally cul- tivated in flower borders, is H. eriocaulon, which is readily known by its very hairy stem, and bracteate racemes ; the stem of H. guttatum being nearly smooth, and the racemes without bractes.

Stem shrubby, erect, not much branched : branches erect, or slightly spreading, with a green glossy bark : the young shoots thickly clothed with short woolly down, and long spreading hairs intermixed, more or less vis- cous. Leaves shortly petiolate, ovately lanceolate, taper-pointed, margins undulate, and slightly denticu- late, the teeth terminated by hairs, strongly 3-nerved from the base, reticulately veined on the lower side, and rugose on the upper : old leaves nearly smooth, young ones hairy on both sides and slightly viscous. Petioles clasping the stem at the base, but not connected, chan- nelled on the upper side, furrowed on each side, and keeled at the back. Peduncles axillary, villosely hairy, terminated by a paniculate cyme, clothed with small oblongly lanceolate, concave, acute, keeled bractes at the base, which are deciduous, and fall off before the expansion of the flowers : upper bractes larger, sessile, oblongly lanceolate, acute, concave, hairy, and fringed. Pedicles slender, cylindrical, villosely hairy. Calyx of 5 sepals, very hairy: 2 outer ones largest, cordate, acute, the sides more or less turned back, much fringed : inner ones narrower, ovate, concave, taper- pointed, the margins scariose or membranaceous. Flowers rather cupped, of a paper white. Petals 5, obcordate, very much imbricate, more or less crumpled, with a light yellow spot at the base. Stamens about 80, spreading, the inner ones longest : filaments smooth, slender, of a pale yellow : pollen bright yellow, inclining to orange. Germen densely clothed with close pressed hairs. Style very short. Stigma large, capitate, slightly 5-lobed, tuberculate. Our drawing and description of this fine species were taken from plants kindly communicated to us from the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham, in June last ; we have no doubt but it is the C. laxus of M. Decandolle, although it belongs to the same division of the section as C. populifolius and lon- gifolius, bearing small deciduous bractes at the base of the peduncles ; we believe the present plant, from the description, to be what is meant by Professor Spren- gel, for C. longifolius, in his Systema Vegetabilium, but very different from Decandolle's C. longifolius, of which we also have a drawing in our possession : the present plant is quite hardy, or only requires slight protection in very severe frost, thriving well in the common garden soil, but prefers rather a dryish situa- tion ; it may also be grown in pots, which can be pro- tected in a frame in severe frost, and may then be planted into the borders in spring ; if grown in pots, the best soil is an equal mixture of light turfy loam, and peat. Young cuttings taken off at a joint, and planted under hand-glasses in autumn, will strike root readily; it may also be increased by layers or seeds. 8 CISTUS corbariensis. Mountain Rock- Rose. Sect.

Stem shrubby, erect, much branched, clothed with a brown glossy bark, more or less warted : branches opposite, spreading', thickly clothed with leaves, smooth or slightly pubescent. Leaves opposite, cordate at the base, ovate, tapering to a point, points a little reflexed, reticulately nerved and rugose, of a dark glossy green on the upper side, and stellately pubescent underneath, slightly glutinous, margins fimbriate with tufts of short hairs. Petioles clothed with a stellate pubescence, and fringed with longer hairs, channelled on the upper side and rounded on the lower, widened at the base and clasping the stem. Peduncles I to 5-flowered, ax- illary, slender, stellately pubescent, nodding before the flowers expand, then becoming erect. Bractes deci- duous, cordately ovate, acute, bluntly keeled, pubes- cent and ciliate. Pedicles thickly clothed with a starry pubescence, at first nodding, then becoming erect. Calyx of 5 sepals ; outer ones largest, cordate, acute, the margins a little recurved ; inner ones membrana- ceous, concave, mucronate. Petals 5, spreading flat, imbricate at the base, the points spreading, obovate or obcordate, slightly crumpled, the margins slightly curved upwards, white with a yellow spot at the base, and tinged with red at the points. Stamens about 100, spreading : filaments short, smooth, straw-coloured : anthers 2-celled, attached near the base by their back to the filaments : pollen orange-coloured. Germen se- riceous. Stigma very large, capitate, papillose, nearly sessile, and hiding the style. Our drawing of this plant was taken at the Nursery of Mr. Colvill, in June last ; it is one of the hardiest species of the genus, thriving well in the common gar- den soil, and in any situation where it is not too moist, continuing to bloom for about two months, and each day covered with a profusion of handsome white flowers, whose margins are tinged with rose ; the rose-coloured buds are also very pretty, before the flowers expand : plants grown in pots make very handsome snug bushes, and have a lively appearance when in bloom ; a mix- ture of loam and peat suits it very well ; and young cuttings, planted under hand-glasses, root without difficulty. This species is a native of mountains in the south of France and Spain, and is sold in the nurseries under the name of C. populifolius minor, but is in reality much nearer related to C. salvifolius than to that species; the C. populifolius $ minor of Decandolle, which is the C. populifolius of Cavanilles, is the C. populifolius major of the Gardens, but is very different from C. po- pulifolius major of Decandolle, a native of Mauri- tania, of which we have a drawing taken from a plant at the Nursery of Mr. Lee, at Hammersmith, the only one that we have ever seen in a living state ; but fine specimens of it are preserved in Mr. Lambert's Her- barium ; it is certainly a very different species from C. populifolius, and we believe no person would con- sider them as belonging to the same that had an oppor- tunity of comparing them when growing together; we therefore propose to name it C. latifolius. 78 CISTUS acutifolius.

Cistus salvifolius /3 humijusus. DC. prodr. 1. p. 265 ? Stem shrubby, branched, spreading : branches long and slender, scarcely strong enough to support their own weight, when young clothed with a short tomen- tum, and stellate bunches of hairs, more or less of a purple tinge, older ones becoming rough, by the little tubercles on which the bunches of hairs have been seated. Leaves ovate, acute, sometimes cordate and sometimes rounded at the base, spreading flat when full grown, afterwards becoming undulate and the sides folded inwards, slightly rugose, 3-nerved at the base, reticulately veined, clothed on both sides and the margins with numerous tufts of short hairs, upper side of a darkish green, paler underneath : young leaves of a hoary appearance, and undulate. Petioles short, di- lated at the base, channelled on the upper side, and convex below, hairy. Peduncles axillary, generally 3-flowered, rough, clothed with a short tomentum and numerous little tufts of hairs. Bractes ovate, acute, opposite, besides some small ones at the base of the pedicles that are deciduous. Pedicles cylindrical, nod- ding before the flowers expansion, afterwards erect, tomentosely hairy. Calyx of 5 sepals, more or less purple, glossy, a little hairy and fringed, acute, .outer ones broadly cordate, inner ones ovate. Petals 5, ob- cordate, white, yellow at the bottom, imbricate at the base, the points distinct. Stamens numerous, spread- x2 ing, unequal in length: filaments yellow. Capsule large, glossy, clothed with short hairs. Stigma large, sessile, capitate, tuberculate. This is probably the plant meant by M. Decandolle as C. salmfolius ]3 humrfusus, as it is the most trailing of any of the genus that we are acquainted with, by which character, its slender shoots, and acute leaves, it is readily distinguished from that species and all others, approaching nearer to C. Cupanianus, but that is a much stronger upright growing plant, with much larger leaves, and of a brighter green ; we have there- fore no doubt but the present is as good a species as any of the others. It is a free growing but dwarf plant, quite hardy, and thrives well in a light sandy soil, con- tinuing to flower successively nearly all the Summer, and ripens its seeds; young cuttings, planted under hand-glasses in Autumn, strike root readily. Our drawing was made from a plant, at the Nursery of Mr. Colvill, King's-road, Chelsea. 23 54 CISTUS saivifolius. Sage-leaved Rock- Rose. Sect. II. LEDONIA. Suprafol.l 1 .

Leaves petiolate, ovate, obtuse or rounded at the points, becoming narrow to- wards the base, more or less rugose, reticulately veined, clothed with fascicles of short hairs on the upper side, and of woolly ones underneath, of a pale green colour, hoary when young, margins sometimes a little undulate, clothed all round with stellate tufts of hairs. Petioles short and broadish, channelled on the upper side, and rounded below, green or sometimes purple, slightly- winged. Peduncles axillary, jointed, one-flowered, dense- ly clothed with short woolly hairs. Bractes 2 or 4 near the base of the peduncle, opposite, broadly lanceolate or ovate, acute.

Sta- mens about 100 '.filaments unequal in length, spreading, yellow : pollen yellow. Germen clothed with a short thin pubescence. Stigma sessile, large, capitate, granular. A great many different species are sold by the name of C. salvifolius at different Nurseries, scarcely any of the Nurserymen knowing the real plant, though it is very readily distinguished from all others, by its solitary one-flowered jointed peduncles, and its obtuse leaves, that are not cordate at the base, and it cannot be easily confused with any other. It is a native of several parts of Europe, and succeeds well in the open air in a shel- tered situation, thriving well in the common garden soil, or, if grown in pots, a mixture of sandy loam and peat will suit it very well. Young cuttings, planted under hand-glasses, any time from the latter end of July, to the beginning of September, will root freely ; they may also be raised from seeds, which ripen in abundance. Our drawing was made from a plant at the Nursery of Mr. Colvill, last Summer. 24. 42 CISTUS obtusifolius. Blunt-leaved Cretan Rock- Rose. Sect. II. LEDONIA. Supra fol 8. 1.

Leaves opposite, sessile, or nearly so, ovately oblong, obtuse, or with rounded points, attenu- ated at the base into a sort of short footstalk, slightly 3-nerved, rugose, reticulately veined, very rough and rigid, clothed on both sides with a starry pubescence, or clusters of short hairs, of a dark green on the upper side, and lighter underneath, margins slightly denticu- late, and fringed with tufts of short hairs: upper leaves quite sessile, and embracing the stem. Flowers termi- nal in a many-flowered cyme. Pedicles rather short and stout, cylindrical, clothed with a white canescence, and longer hairs intermixed. Calyx of 5 sepals, the outer ones broadly cordate, acute, hairy on both sides, the margins slightly reflexed : inner ones ovate, taper-point- ed or mucronate, with scariose membranaceous mar- gins. Petals 5, obcordate, a little crumpled, white, with a yellow spot at the base, imbricate at the base, the points spreading. Stamens about 100, spreading, overtopping M 2 the stigma : filaments unequal in length, slender, bright yellow. Germen clothed with silky hairs. Style very short, erect, hid by the large, capitate, slightly 5-lobed, papillose Stigma. We have seen some fine specimens of this plant in the Herbarium of A. B. Lambert, Esq. who received them from Crete under the name of C. salvifolius, but it is very different from that species, or any other with which we are acquainted ; it forms a pretty little com- pact bush, which is covered with flowers a good part of the Summer; the plants that we have seen have not been more than a foot to eighteen inches in height, and very bushy, and it appears to be one of the dwarfest grow- ing species of the genus. Being a native of Crete, it requires a little shelter in severe frost, either to be covered with mats, or some other covering, if planted in the open ground : but if grown in pots, it may be protected in a frame or Green- house in frosty weather, and can then be turned out in the borders in Spring. It thrives well in any light sandy soil, or a mixture of light sandy loam and peat will suit it very well. Young cuttings, planted under hand- glasses in August or September, will strike root readily. Our drawing was made at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham ; and it was most probably first introduced from Greece by Dr. Sib- thorp, and has been in our collections ever since, with- out being noticed as a distinct species. 19 CISTUS hirsutus.

Stem shrubby, very much branched : branches spread- ing, thickly clothed with unequal spreading hairs. Leaves opposite, sessile, oblong, obtuse, more or less undulate, 3-nerved at the base, rugose, strongly nerved underneath, the nerves much branched, hairy on both sides, the margins fringed : upper ones much broader than the lower ones, particularly towards their base, and more hairy, also more strongly 3-nerved. Flowers terminal, generally cymose, seldom solitary. Pedicles short, villosely hairy, slightly viscous, cylindrical. Ca- lyx large, broad at the base, with a taper point, or py- ramidal ; sepals 5, villosely hairy, the hairs white and spreading : outer ones very broadly cordate, acute, leafy, their margins recurved or revolute: inner ones smaller, ovate, with taper points, their margins mem- branaceous. Petals 5, obovate or obcordate, imbricate, white, yellow at the base. Stamens about 100, unequal in length, spreading, far overtopping the stigma: fila- ments smooth, pale yellow : pollen bright yellow. Ger- men rough, pubescent. Style very short, erect. Stigma large, capitate. This pretty plant is a native of Spain, and some other parts of the South of Europe, and is readily distin- guished from all others by its very large pyramidal calyx and small capsules; it is often confused with C. laxus in the nurseries ; but a comparison of our figures will readily distinguish them. The present plant is hardy enough to bear our Winters in the open borders without protection, except very severe ones, when a mat placed round it will preserve it well ; but this is very seldom needed : when grown in the ground it is much more robust than the plant from which our drawing was made, which was grown in a pot ; it pro- duces a great profusion of flowers, which continue to expand in succession for a considerable time. Our drawing was taken at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham, last Summer, where we have also obtained drawings of many very rare, and some quite new species : the present plant thrives well in the common garden soil ; or if grown in pots, it succeeds best in a mixture of sandy loam and peat. Young cuttings, planted under hand-glasses in August or September, or any time between that and the middle of February, will strike root freely ; when they are rooted, they must be managed as mentioned under C. purpureus; young plants may also be raised from seeds, which ripen plentifully. 47 CISTUS platysepalus.

Stem shrubby, very much branched : branches spread- ing in all directions, erect or ascending, thickly clothed with long spreading villous white hairs. Leaves lan- ceolate, or oblongly-lanceolate, sessile, 3-nerved from the base, rugose, reticulately veined underneath, clo- thed on both sides with long villous hairs, the mar- gins fringed : lower ones bluntish and narrowest ; upper ones broad at the base, ovately lanceolate, many nerved and acute. Flowers terminal, in a branching cyme. Peduncles thickly clothed with villous spread- ing hairs. Bractes leaf-like, deciduous, ovate or ovately lanceolate, acute. Pedicles short, scarcely as long as the calyx, villous. Calyx of 5 sepals, the outer ones broadly cordate, taper-pointed, villosely hairy on both sides, and fringed, the margins bent back a little: inner ones narrower, oblong or ovate, taper-pointed, concave, membranaceous, villous at the back, and smooth inside. Petals 5, distinctly spreading, not im- bricate, obcordate, more or less crumpled, narrow at the base, white with a small yellow spot at the base. Stamens numerous, about 80, very unequal in length, overtopping the stigma : filaments slender, smooth and yellow : pollen yellow. Germen hairy. Style short, erect. Stigma large, capitate, papillose, covering the short style, like an umbrella. The present plant is generally confused with C. mons- peliensis in our gardens, though no two plants need be more distinct, and it is much nearer related to C. hir- sutus. It is a native of Crete, as we have ascertained by fine specimens in Mr. Lambert's Herbarium re- ceived from that country, and also marked C. monspe- liensis ; but a comparison with our figure of that spe- cies, or the figure in the Flora Graeca, will easily decide the difference ; we do not know when the pre- sent plant was introduced, but it was most probably brought by Dr. Sibthorp on his return from Greece. We have not yet been fortunate enough to find C. creticus in any collection that we have visited, and fear that it is quite lost to the country ; but it may probably still exist in some collection ; should any of our Subscribers or their friends possess the plant, we should feel much obliged for specimens of it when in flower, the plant now known in Nurseries by that name being C.purpureus. As the present plant is a native of Crete, it requires a little protection in severe frosty weather, either the covering of a mat, or to be protected in a frame, thriv- ing well in a light sandy soil, and may be increased by seeds, or young cuttings planted under hand-glasses in August or September, will soon strike root. Our drawing was made at the Nursery of Messrs. Whitley, Brames, and Milne, near Parsons Green, Fulham. 33 CISTUS psilosepalus. Smooth Sepaled Rock- Rose. Sect. II. LEDONIA. Supra, fol. 1. 1.

Cistus psilosepalus. Swt. hort. brit. addenda, p. 468. Stem shrubby, much branched ; branches spreading, roughish, of rather a rusty appearance, thickly clothed with tufts of longish rigid hairs. Leaves on the stem with short footstalks, oblongly lanceolate, acute, three- nerved underneath, reticulately veined, of rather a glossy green on the upper side and paler underneath, hairy on both sides, the hairs underneath in little tufts ; margin much undulate, rough or a little denticulate, and fringed with tufts of short hairs, and some longer ones intermixed : the leaves on the flower-stems sessile, connected at the base, more prominently three-nerved, and the points less sharp. Flower-stems axillary and terminal, also clothed with tufts of short hairs, and some long ones intermixed. Peduncles clothed with tufts of short woolly hairs, and some longer ones inter- mixed. Calyx of 5 sepals, the 3 outer ones broadly cordate, with long taper points, striated with nume- rous faint lines, which are branched a little, smooth and glossy, the margins fringed ; inner ones ovate, membranaceous, with long subulate points. Petals 5, K broadly wedge shaped, very much imbricate, of a thin texture and much crumpled, of a pure white with a faint yellow mark at the base of each. Stamens nume- rous, about 150, spreading : filaments smooth, pale yellow, of various lengths ; pollen yellow. Germen to- mentose. Style very short, quite hid by the large capi- tate, slightly 5-lobed, papillose Stigma. Our drawing of this plant was taken from one grow- ing in the open border, at the Nursery of Mr. Lee, at Hammersmith, in July last; it appears to us to be quite new and nondescript, differing from all others with which we are acquainted by its smooth glossy sepals, and also in the shape of its leaves, approaching the nearest to C. longifolius, but still very different from that species ; the plants were very bushy, and the shoots were terminated by large cymes of white flowers, which open in succession, and make a fine contrast with the dark green leaves with which the plants are clothed. It succeeds well in the common garden soil, in rather a dry situation, and would thrive well on rock- work ; or if grown in pots, a mixture of sandy loam and peat would suit it very well. Cuttings planted under hand-glasses in Autumn, strike root freely. '- 59 CISTUS florentinus, Florentine Rock-Rose. Sect. II. LED ONI A. Supra fol 1. . 1.

Leaves linearly lanceolate or sometimes oblongly lanceolate, undulate, acute, tapering to the base, upper ones sessile and broad at the base ; lower ones taper- ing to the base into a sort of footstalk, 1 -nerved, pen- nately and reticulately veined, the points a little recur- ved ; when young clothed with numerous bunches of short hairs, and a sort of thin tomentum underneath, the hairs mostly curved upwards towards the point, stiff and rigid, which causes a roughness; old ones be- coming smooth and glossy, and more or less tinged with purple. Bractes or leaves on the flower-stem, sessile, three-nerved from the base. Peduncles and pedicles clothed with spreading hairs and shorter down inter- mixed, which gives them a hoary appearance, the pe- duncles 2 or 3-flowered. Flowers white. Calyx of 5 se- pals, which are villosely hairy, and taper to a long slen- der point, the outer ones cordate at the base, and the margins slightly reflexed, more or less tinged with pur- ple : inner ones narrower. Petals 5, white, tinged with red at the points, and a yellow spot at the base, broadly obovate, imbricate their whole length, spreading flat, or sometimes slightly cupped. Stamens numerous, spread- ing, unequal in length : filaments short, smooth, yellow : pollen golden yellow. Germen tomentose. Stigma capi- tate, sessile, very large, tuberculate. Our drawing of this rare and very distinct species was made at the Nursery of Messrs. Whitley, Brames, and Milne, in July last, the only collection in which we have ever seen it ; but we hope it will now soon be- come more plentiful, as it forms a pretty upright bush, and makes a neat appearance when covered with bloom ; we suspect it will also bear our Winters without pro- tection, particularly if placed in a sheltered situation, thriving well in any light sandy soil ; and young cut- tings, planted under hand-glasses, in August or Sep- tember, will strike root freely. _ 27 .r&fa CJSTUS monspeliensis.

Stamens very short, but overtopping the stigma, about 50 : filaments une- qual in length, smooth, yellow. Germen pubescent. Style short, straight. Stigma large, capitate, granular. The present species is not a common inhabitant of our collections, and another species, a native of Crete, is often confused with and sold for it at the Nurseries, although no two plants of a section can well be more dissimilar; we have also seen them confused in the Herbariums ; and in a collection of Cretan specimens lately received by Mr. Lambert were fine specimens of it, marked C. monspeliensis, though it is much nearer related to C. hirsutus. As the present plant is so scarce in collections, we are inclined to believe that it is more tender than some other species, particularly as it is a handsome growing plant, and an abundant bloomer ; it should therefore be planted in a warm border, or where it can receive some protection in severe weather. Plants of it may be grown in pots, and can then be protected in frames in Winter ; it succeeds well in any rich light soil, or a mixture of sandy loam and peat will suit it very well. Cuttings planted under hand- glasses in Autumn will strike root readily, but the glasses must not be kept too close on them for any length of time, or they will be very liable to damp and turn mouldy.

It thrives best in a light sandy soil, and may be propagated by layers, or from seeds, that ripen in abundance. CISTUS ladaniferus p. macuiatus. Spotted-flowered flat-leaved Gum Cistus. CISTUS.

This beautiful species must not be confused with the plant generally known by the name of Gum Gistus in the gardens, and also confounded with this in Curtis's Botanical Magazine, t. 112; the plant there figured is C. Cyprius of M. Decandolle's Pro- dromus, and differs from the present in bearing 3 or more flowers on each peduncle ; the leaves are also petiolate, and the capsules only 5-locular ; differences which readily distinguish it from our plant, which we believe is the largest flowered species of the genus. It is not so hardy as C. Cyprius, and will not survive our winters in the open air, except very mild ones, but will thrive well against a wall, so as to be covered with mats in severe weather, and a little dry litter put on the ground to keep the frost from the roots ; it is also a good plan to keep some plants in pots, to be preserved through the winter in frames, and to be turned out of them in the open ground in spring ; they will then thrive well, and flower in fine perfection. It succeeds well in a rich light soil, and prefers a dryish situation, as its roots are apt to rot if it happens to get too much moisture. It may be increased by cuttings or layers ; the former must be taken off as soon as the young shoot is ripened, and they must be planted thinly under hand-glasses, for if planted too thick, they will be liable to damp. Our drawing was taken from a plant at the Nursery of Mr. Colvill, King's Road, Chelsea. We also re- ceived specimens of it from Malcolm and Gray's Nursery, Kensington. 33-, CISTUS cyprius.

Stem erect, much branched : branches spreading, glossy, viscous. Leaves opposite, petiolate, connected at the base, and sheathing the stem, oblongly lanceolate, acute, more or less undulate, up- per side smooth and glossy, viscous ; underneath 3-rierved from the base, reticulately veined, and clothed with a dense white tomentum. Flowers terminal, in a many flowered umbel. Peduncles bracteate. Bractes decus- sate, deciduous; the bottom ones smallest, and soon dropping, lanceolate, taper-pointed and keeled : upper ones ovate, concave, taper-pointed, keeled, the margins densely fringed with white hairs. Pedicles fasciculately hairy, viscous. Calyx of 3 sepals, or very rarely of 4 or 5 sepals: sepals broadly ovate, acute, concave, the mar- gins scariose or membranaceous, inside punctate, and striped with numerous lines, outside scaly, or clothed with fascicles of very short hairs, having the appearance of scales. Petals 5, broadly cuneate or obcordate, more or less crumpled, imbricate, margins uneven or crenu- late, white, with a yellow spot at the base, and a large bright purple spot above it, which is more or less branched. Stamens short, about 150, unequal in length, the inner ones longest: filaments slender, pale yellow. Germen tomentose. Style hid by the stigma. Stigma very large, capitate, papillose. The present plant being one of the handsomest, and also being pretty hardy, is more generally cultivated than any other species ; and in all the collections where we have seen it, it has been considered as the C. lada- niferus, and that species in the Nurseries is sold under the name of C. salicifolius. In Curtis's Botanical Ma- gazine, the present plant is also named C. ladaniferus, and the figure is referred to as such in the last edition of the Hortus Kewensis, though no two species can be more distinct, the present bearing several flowers in a cyme, the buds not half the size of C. ladaniferus, the capsule only 5-celled, and of a very different shape, and the leaves petioled : C. ladaniferus always produces its flowers solitary, which are also larger, its capsule is from 7 to 10-celled, and its leaves are flat and sessile; it is much more distinct from the present plant, than the present is from C. laurifolius, of which it is con- sidered as a variety by Persoon: the present plant thrives well in the open border, and ripens plenty of seeds ; but it is best to have some young plants also in pots, to be preserved in frames in severe Winters, which will occasionally destroy the old ones. Young cuttings, planted under hand-glasses in Autumn, will strike root; but the best way is to raise them from layers or seed. Drawn at Mr. Colvill's Nursery, in July. 52 CISTUS laurifolius.

S'/em shrubby, erect, much branched : branches spread- ing, densely clothed with fascicles of short hairs, which press inward to the stem, upper part glutinous. Leaves opposite, petioled, ovate or ovately lanceolate, acute, very much undulate at the margins, three-nerved from the base, upper side smooth, of a dark green, and vis- cous ; underneath clothed with a short dense white to- mentum, which wears off by age, and the leaf is then very much reticulated underneath. Petioles deeply channelled on the upper side, and convex or keeled on the lower, widened at the base, where they are con- nected, and clasp the stem, thickly clothed with tufts of short hairs. Peduncles long, cylindrical, clammy, many-flowered, either panicled, corymbose, whorled or umbellate. Bractes ovate, acuminate, convex, downy, more or less of a red colour, but deciduous, and falling off before the expansion of the flowers. Pedicles cylin- drical, densely clothed with fascicles of unequal hairs, the points of which bend inwards. Calyx of 3 sepals, which are ovate, taper-pointed, convex, or concave inwards, with one margin rnembranaceous, the other fringed, thickly clothed with longish spreading white hairs. Petals 5, more or less imbricate, cuneate, more or less crumpled, white with a light yellow spot at the base. Stamens about 180, the filaments unequal in length, smooth, light yellow : pollen golden yellow. Germen villous. Style short, pubescent. Stigma capi- tate, 5-lobed, papillose. A hardy strong .growing handsome Shrub, which makes a fine appearance with its large green Laurel- like leaves, and produces an abundance of flowers ; those even in the bud state are very ornamental, when covered with their large light red bractes, having the appearance of Rose buds. It thrives well in the com- mon garden soil, and needs no protection, being quite hardy, and maybe raised in abundance by seeds, which ripen plentifully ; it may also be raised from layers; or young cuttings, planted under hand-glasses in Au- tumn, will strike root. Our drawing was made last Summer at the Nursery of Mr. Mackay, then of the King's Road, but now removed with his whole collection to the more healthy and pleasant situation at Clapton, where he cultivates, with great success, the choicest selection of New Hol- land plants ever introduced to this country.

Stem shrubby, erect, or more or less spreading, from 9 to 18 inches in height, clothed with a hard brown glossy bark, much branched : branches, while young, viscous, clothed with short woolly hairs. Leaves op- posite, crossing each other, sessile, linearly oblong, bluntish, with revolute margins, more or less ciliate, when young, pubescent and viscous : upper side of a dark glossy green ; underneath reticulately veined, and clothed with a dense rusty white tomentum. Flowers white, numerous, terminating the branches in a whorled raceme, and ending in an umbel. Bractes ovate, acute, concave, keeled at the back, membranaceous, dropping off when the flowers expand. Pedicles in whorls round the stem, slender, one-flowered, viscous and pubescent. Sepals 3, cordately ovate, acute, con- cave, villous, about half the length of the petals. Pe- tals 5, of a pure white, with yellow unguis, roundly obovate, or obcordate, imbricate at the base, at first cup shaped, afterwards flat, and at last reflexed. Sta- mens about 16, nearly erect, the outer ones scarcely c half as long as the inner ones, and more spreading : filaments slender, smooth : pollen orange- coloured. Germen densely tomentose. Style smooth, about the length of the stamens. Stigma capitate, slightly 3-lobed, tuberculate. This handsome and very distinct species, is a native of France, Spain, and Portugal, and is said to have been cultivated in this country as far back as 1731 ; it is a pretty plant for ornamenting rock- work, but is liable to be injured in very severe winters, except co- vered with mats or a little dry litter in severe frost ; if there happen to be a sufficiency of snow on the ground, that will answer the purpose ; but it is best to have some plants of it in pots, that may be pro- tected in a frame in severe weather ; those can be turned out in the ground in Spring, where they will thrive and flower well. The present plant is generally sold in the nurseries by the name of Cistus Libanotis, which is a very dif- ferent species, and appears to be much more rare than this plant, as we have not been able to detect it this Summer in any collection that we have examined ; this species varies considerably in habit and pubescence, according to the situation in which it is grown ; if grown under glass, it is much more pubescent, and the leaves are strongly fringed, as in our figure ; but when grown in the open air, the leaves are quite smooth and glossy, with scarcely a vestige of pubescence, ex- cept on the under side, where they are clothed with a dense tomentum ; we, therefore, believe the two varie- ties of M. Decandolle to be occasioned only by differ- ence of situation ; we have accordingly united them. Our drawing was taken from a plant lent us from the Nursery of Mr. Lee, at Hammersmith, in June last ; it thrives well in small pots, in a mixture of sandy loam and peat, and continues to bloom in suc- cession from June to August. Young cuttings, planted under hand-glasses, strike root readily ; it may also be raised from seeds, which ripen plentifully. 13 HELIANTHEMUM ocymoides Basil-like Sun- Rose. Sect. I. HALIMIUM.

Petioles short, also densely clothed with a close pressed white to- mentum. Flowers on a long branched panicle. Pedun- cles of a brownish purple, glossy, more or less clothed with long spreading white hairs. Bractes sessile, opposite, ovately lanceolate, acute, keeled, points a little recurved, smooth and glossy. Pedicles 3 or more flow- ered, in a kind of umbel, opposite on the lower part of the panicle, on the upper part alternate. Calyx smooth and glossy, with a long taper point, green, tinged with purple: sepals 3, oblongly lanceolate, concave, the margins scariose and membranaceous. Petals 5, ob- cordate, distinct to the base, a little cupped, margins slightly crenulate, of a golden yellow, with a large black spot a little above the base, edged with purple. Stamens between 40 and 50, overtopping the stigma : filaments very unequal in length, smooth and very slender, bright yellow: anthers dark purple : pollen bright yellow. Germen clothed with silky hairs. Style very short, erect. Stigma capitate, 3-lobed, papillose, flesh-coloured. This very handsome species, of which there is a good figure in Cavanille's Icones, is very often confused in the collections with H. algarvense, as is several other species that are belonging to the same section ; we have had them all sent to us as H. algarvense, though dif- ferent in every respect from that species, except in co- lour. The present plant is a native of the South of Europe, so that it requires the protection of a frame in Winter, or to be planted against a south wall, and to be covered with mats in severe frosty weather ; or if planted in rock- work, it should be placed on the south side, and should be covered with a mat or by some other means in sharp frosty weather, but in mild wea- ther, the more it is exposed the better : it succeeds well in a light sandy soil, or if grown in pots, an equal mixture of sandy loam and peat will suit it very well. Cuttings taken off at a joint in the young wood, and planted under a hand-glass, the latter end of Summer, or in Autumn, will soon strike root, and will be nice bushy flowering plants by Spring. Our drawing was made from a plant at the Nursery of Mr. Colvill, in July, 1823; the plant from which it was taken was rather drawn up in a greenhouse ; it generally grows more compact. 96 HELIANTHEMUM microphyllum.

Leaves numerous, nearly sessile, crowded, small, oblongly ovate, nearly round, or some- times lanceolate, bluntish or scarcely acute, very narrow towards the base, undulate, the sides curved inwards, sharply keeled underneath, very stiff and rigid, densely clothed with a close-pressed dark canescent tomentum, margins rough. Panicle terminal, leafless, very long and loose, thickly clothed with stiffish spreading purple hairs, that are unequal in length, lower branches of the pani- cle opposite, the upper ones alternate. Pedicles very short, torn entosely -hairy, one to three-flowered. Calyx of 3 se- pals, that are ovately lanceolate, concave, very taper- pointed, densely clothed with woolly hairs, of unequal lengths, tinged with purple. Petals 5, not at all imbri- cate, but distinctly spreading, wedge shaped, very nar- row at the base, more or less crumpled or undulate, of a bright yellow, with a smallish dark purple spot on each, a little above the base. Stamens from 80 to 100; filaments smooth, unequal in length, of a pale yellow : anthers yellow, with a purple spot at the point : pollen granular, orange-coloured. Stylehid by the large capi- tate granular Stigma. Our drawing of this handsome species, was made from a fine plant, in the garden belonging to the Apothe- caries' Company, at Chelsea, the only collection in which we have seen it, and where it was grown in a pot, and preserved through the Winter in the Greenhouse; it is one of the latest flowering species, and is nearly related to H. atyssoides and H. rugosum, but in our opinion is sufficiently distinct from both, being readily distinguish- ed from all its congeners, except H. ocymoides, by its small leaves, and from that by their different form, and the habit of the plant : like the other plants of the sec- tion to which it belongs, it is rather tender, requiring a little protection in severe frosty weather, either to be planted near a wall or fence, and to be covered with a mat, or to be grown in pots, and to be protected under a frame, or in the Greenhouse ; a mixture of light sandy loam and peat is the best soil for it ; and young cut- tings, planted under hand-glasses in Autumn, soon strike root. rqr. 7an.28l7. 40 HELIANTHEMUM algarvense Algarvian Sun- Rose.

Stem shrubby, much branched, growing to the height of 2 or 3 feet if supported, erect or flexuose, seldom growing in the manner represented in the Botanical Magazine; branches more or less flexuose, densely clothed with a close pressed white tomentum, and a few spreading white hairs intermixed. Leaves opposite, ses- sile, very much attenuated towards the base, with blunt points, greenish and hairy on the upper side, and clothed with a thin tomentum underneath : lower ones short, roundly ovate, and green on both sides : upper ones ovately lanceolate or spathulate, slightly 3-nerved, clothed with a thin white tomentum on the lower side, and with little fascicles of hairs at the margins, which gives them an appearance of being crenulate: young leaves white on both sides. Flowering branches a little panicled, leafy at the base, clothed with spreading slen- der hairs, but not woolly as on the other branches. Pe- duncles and pedicles slender and hairy. Calyx of only 3 sepals, which are nearly equal, lanceolate, taper point- ed, and clothed with long spreading loose white hairs. Petals 6, spreading, nearly or sometimes quite distinct to the base, but when first opened, imbricate: obovate or broadly cuneate, with crenated points, of a bright yellow, with a large velvet spot at the base, which is also toothed in appearance ; the spot at the base of each petal gives the appearance of a dark circle at the base of the flower. Stamens about 50, either more or less: filaments very unequal in length, of a dark purple, yel- low at the base, smooth. Germen woolly. Style very short, hid by the large capitate, slightly lobed, pustu- lose Stigma. The present plant being so much like some others, with which it is confused in many of the Nurseries, that we were afraid it had disappeared altogether, until we saw a plant of it last Spring in full bloom at Mr. Mac- kay's Nursery at Clapton, from which our drawing was taken; we have since seen it also at Mr. Lee's Nursery at Hammersmith. It is nearly related to H. ocymoides, but that is readily distinguished by its long taper-point- ed glossy sepals, from H. rugosum; it is also distin- guished by that having its petals imbricate, and its se- pals clothed with stiff reddish brown bristles, not soft woolly hairs like the present. This being a native of the South of Europe, it re- quires some protection in Winter ; if planted in rock- work, or against a wall, it will require to be protected by a mat, or some covering in sharp frosty weather; or if grown in pots, it may be kept in frames or in the Greenhouse, where its lively blossoms in Spring make a pretty appearance ; a light sandy soil suits it best, or a mixture of light turfy loam and peat will suit it very well. Cuttings, planted under hand-glasses, root freely, any time from July to September. /216. HELIANTHEMUM candidum. White-leaved Sun-Rose. Sect. I. HALIMJUM.

Stem shrubby, erect, much branched, clothed with a brown warted bark : branches erect, or slightly spread- ing, densely clothed with a close pressed white tomen- turn, and a few long spreading hairs intermixed. Leaves opposite, lanceolate, or lanceolately obovate, bluntish, or scarcely acute, flat, or the margins of the round leaves folded inward, attenuated at the base into a sort of footstalk, clothed on both sides with a dense white tomentum, and long spreading white hairs on the upper side; underneath slightly 3-nerved, and very rough, occasioned by small tubercles, on which grow short tufts of hairs ; those on the flower stems, opposite, green on both sides, more strongly 3-nerved, with a few long spreading hairs on the upper side, and tufts of short hairs seated on little rough tubercles underneath. Flower-stems long, paniculately branching, smooth and glossy, or a few hairs scattered here and there. Bractes elliptically lanceolate, acute, keeled at the back. Pe- dicles glossy, slightly warted. Calyx varying, with 3, 4, or 5 sepals ; outer small sepals spreading, linear, scarce- ly acute, smooth and glossy ; inner ones lanceolately ovate, concave, taper-pointed, with membranaceous margins, villosely hairy, more or less tinged with H purple, one or both of the small sepals are sometimes wanting. Petals 5, very much imbricate, of a bright yellow, with a dark velvetty spot near the base, edged with purple. Stamens from 50 to 60, surrounding and overtopping the stigma : filaments unequal in length, smooth, yellow at the base, and dark purple upwards : anthers dark purple : pollen yellow. Germen densely clothed with close-pressed silky hairs. Style very short, erect, nearly hid by the large capitate, papillose Stigma. Our drawing of this very fine plant was taken at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham, last Summer, where it was cultivated as H.Z- garvense, which is a very different species, and is now become rather scarce in our collections ; and we had al- most been inclined to believe it was lost altogether, until we saw a fine plant of it in full bloom, at the Nur- sery of Mr. Mackay, at Clapton, from which we have obtained a figure ; we have met with several other spe- cies of this section, which have all been confused in the collections where we have seen them, either with H. al- garvense, or H. hatimifolium. We last year received a very handsome and distinct species from Mr. Miller, of the Bristol Nursery, which is related to H. algarvense ; it did not arrive in a state fit for drawing, but it is now very fine in bloom, and we believe will prove to be H. rugosum of Decandolle ; its calyx consists of only 3 sepals, which are ovate, and thickly clothed with brown rigid hairs, which at once distinguishes it from all others ; its flowers are not so large as the present plant, nor are the petals so much imbricate ; the leaves are also of a thinner texture, very much undulate and twisted, and very rough or denticulate on the margins. We have been informed by M. Lagasca, that the present subject is a native of Spain, and he is certain that it is a nondescript species ; it will thrive well in a warm border by the side of a wall, or may be grown in a pot, and protected in a frame in Winter ; it is readily increased by cuttings planted under a hand-glass, in Autumn.

Stem shrubby, erect or a little flexuose, much bran- ched, in our specimen from 3 to 4 feet high : branches spreading, elongated, more or less hairy, and clothed with a dense leprous tomentum, which by age becomes of a brownish grey, and is densely spotted with innu- merable minute black specks. Leaves variable, when young quite white and hairy on both sides, sessile, obovate, or oblong, more or less undulate and twisted, a little oblique, three-nerved at the base, very rough and uneven, the margins very rough or denticulate ; lower ones shortest and broadest, ovate or obovate, bluntly rounded, attenuated into a sort of footstalk at the base, clothed on both sides with a thin white tomentum : the next are narrower and longer, and less blunt, of a greener colour, less tomentose, not so narrow at the base, more undulate and twisted ; upper ones, when young, quite white on both sides, much more hairy, ses- sile, and acute : those on thejftower-stems quite sessile and clasping the stem, much broader, ovate, acute, s many -veined or lineate underneath, green on both sides, rough and hairy but not tomentose, longer than the pe- duncles, except when drawn up within doors. Flower- stems terminal or axillary, thickly clothed with unequal soft spreading weak hairs. Peduncles in a sort of pani- cle, terminal or axillary, 1 or 2-flowered, oftentimes in a sort of umbel, shorter than the leaf, at their base Of a brownish purple colour, thickly clothed with soft spreading hairs that are purple at the base, the leaves at the base of the peduncles are fringed with purple hairs. Calyx of 3 sepals, densely clothed with rigid purple bristle-like hairs : sepals broadly ovate, acute, concave, with membranaceous edges, a little keeled at the back. Petals 5, broadly obovate, finely crenulate, very much overlapping each other, of a golden yellow, each with a large dark spot near the base, which bran- ches a little. Stamens from 40 to 45, spreading : fila- ments smooth, unequal in length, of a bright yellow, with purple points : anthers dark purple before burst- ing : pollen orange-coloured. Germen densely tomen- tose. Style very short. Stigma large, capitate, pustu- lose. For the opportunity of giving a figure of this hand- some plant, w r e are obliged to Mr. J. Miller, of the Bristol Nursery, from whom we received it, and it is readily distinguished from all others of the section to which it belongs, by the stiff bristle-like purple hairs on the calyx ; as far as we can judge by the descrip- tion, we believe it to be the H. rugosmn of Dunal, in Decandolle's Prodromus, which is a native of Portugal. It succeeds well in a light soil, consisting of an equal portion of sandy loam and peat, and if planted by the side of a wall in a southern aspect, and covered with a mat in severe frost, it will succeed very well, or it may be grown in pots, and kept under glass in frames, or in the Greenhouse in frosty weather, but should be ex- posed to the air as much as possible when the weather is mild ; the time of flowering is from June to August. Cuttings, planted under hand-glasses, in August or September, strike root readily. JHar-tDei 50 HELIANTHEMUM formosum, Beautiful Sun- Rose. Sect. I. HALIMIUM.

Leaves oppo- site, crossing each other, very shortly petiolate or scarcely sessile, ovate, or obovately lanceolate, obtuse, underneath 3-nerved at the base, the nerves more or less branched: young ones densely clothed with a close white tomentum on both sides, and spreading villous hairs intermixed ; old leaves smoother and greener, the hairs on them in stellate fascicles underneath, and spreading on the upper side. Petioles very short, vil- losely canescent. Flowers terminating the branches in a paniculate cyme. Bractes leaf-like, concave, becom- ing deciduous. Peduncles generally 3-flowered, vil- losely tomentose. Pedicles and Calyx densely clothed with a white tomentum, and long villous hairs inter- mixed ; amongst these are other straight rigid purple hairs, which gives a brownish appearance. Calyx of 3 sepals, which are ovate, concave, tapering to a point, with scariose membranaceous margins, tinged with red on one side. Petals 5, obcordate, much imbricate, of a o 2 bright yellow, with a large brownish purple spot near the base, lightest on the upper part, and slightly bran- ched. Stamens about 40, overtopping the stigma, the inner ones longest : filaments slender, smooth, yellow : pollen orange-coloured. Germen downy. Style hid by the large Stigma, which is capitate, slightly 3-lobed> and papillose. We believe the present to be the largest flowered spe- cies of the genus, and makes a handsome upright bushy Shrub, but will scarcely endure our Winters in the open air without protection ; it makes a pretty plant for the Greenhouse, and succeeds well by the side of a wall in a southern aspect, so as to be protected with covering in Winter, thriving well in any rich light soil, and pro- ducing a great quantity of flowers in succession : plants of it may be preserved in pits or frames through the Winter, so as to be kept from the frost, they may then be turned into the borders in Spring, where they will make a fine appearance in Summer : young cuttings, planted under hand-glasses in Autumn, soon strike root ; seeds also ripen in abundance ; so that any quan- tity may be raised ; but as the colour of the flowers vary considerably on different plants, the seeds should always be saved from those of the brightest colours.

A handsome small bushy shrub, with spreading, ra- ther crooked branches, that are densely clothed with bunches of short hairs, and long soft villous ones inter- mixed : as the hairs wear off, the stem becomes rough, the hairs being seated on a sort of small warts or tuber- cles, when young white or greyish, afterwards becom- ing brown. Leaves opposite, sessile, but attenuated or becoming gradually narrower towards the base, where they are three-nerved, oblongly ovate, or sometimes lanceolate, generally acute, but sometimes obtuse, very much undulate at the margins, which are generally re- flexed or rolled backwards, hairy on both sides, and rough to the touch, particularly on the under side, up- per side pale green, underneath very white while young, but becoming greener by age. Stipules none. Flowers bright yellow, without spots, terminating the branches, generally from 2 to 5 in a sort of panicle, which would probably be more numerous iu a strong plant. Bractes lanceolate, acute, very hairy. Pedicles scarcely so long as the longest leaves, densely clothed with short rough bristle-like hairs, and short down intermixed. Calyx of 3 sepals, that are ovate, concave, tapering to a long slender point, clothed with numerous short rough brown hairs, and short pubescence intermixed. Petals 5, dis- tinctly spreading, not at all imbricate, of a bright gold- en yellow, very broad at the ends, but slightly retuse, and crenulate, tapering very much to the base. Sta- mens about 80, spreading : filaments unequal in length, bright yellow : pollen golden yellow. Ovarium rough, much punctated with small dots, clothed with a short pubescence, but glossy. Style short, hid by the large stigma. Stigma capitate, peltate, papillose. Our drawing of the present species was made last Summer from a plant sent to us by Mr. J. Miller, from their extensive and valuable collection at the Bristol Nursery ; and we have not met with it in any of the col- lections about London. It is a native of Portugal, and requires the same treatment as H. formosum, to be grown in a light sandy soil, and if planted in a shel- tered situation, or by the side of a wall in a southern aspect, it will stand through the Winter without being injured; but should the Winter be very severe, it would be requisite to cover it with a mat in the hardest frost ; or it may be grown in pots, which can be pre- served in frames through the Winter, to be only covered up in frosty weather. Cuttings of it, planted under hand- glasses in August, will strike root readily, but as soon as rooted they will require to be hardened by degrees to the air, or they will otherwise damp off.

Leaves opposite, or the upper ones alternate, oblongly lanceolate, three-nerved, attenuated into a sort of petiole at the base, thickly clothed on both sides with a close white woolly pubes- cence, which gives them a white hoary appearance ; the lower ones broadest, and bluntish ; the upper ones nar- row and acute. Peduncles generally 2-flowered, densely clothed with woolly hairs that are seated on small dark warts. Flowers bright yellow, with no spot of red or purple. Calyx of 5 sepals ; thickly clothed with dense wool: the two outer ones very small, spreading: the three inner ones broadly ovate, inclining to heart sha- ped, terminated in a long taper point. Petals 5, ob- cordate, or broadly cuneate, hollow at the ends and uneven, imbricated over each other, spreading flat when fully expanded', of a plain bright yellow. Stamens nu- merous, surrounding the germen : filaments orange-co- loured ; pollen golden yellow. Germen conical, downy, terminated by a broad, nearly sessile, capitate Stigma. The present handsome species is a rare plant in our collections ; the only one that we have seen of it was sent us by the kindness of Mr. J. Miller, from his Nur- sery at Bristol, a collection that is very rich in this hand- some family of plants ; another fine strong growing spe- cies belonging to this section, H. atriplicifolium, with large glaucous leaves resembling Atriplev Halimus, has we believe quite disappeared from our collections, though we recollect when it was very abundant ; this is also the case with Cistus Ledon, which we do not remember hav- ing seen for the last ten years, many of those plants being lost, through their possessors not knowing what they were, and the protection that they require, and also by confusing them with others. The present species is nearly hardy, requiring only a slight covering in se- vere frosty weather, and some young plants of it may be grown in pots, to be protected in frames or the Greenhouse in. Winter ; a light sandy soil suits it best, or, if grown in pots, a mixture of turfy loam and peat is most proper for it ; young cuttings, planted under hand-glasses, in a shady situation, any time through the Spring or Summer, will root readily; and the sooner they are potted off after they are rooted, the better, or the glasses left off them, as they are very liable to damp off.

Peduncles long, leafy, paniculately branching, smooth and glossy, with a few long slender spreading hairs scattered on them ; lower leaves opposite, upper ones alternate. Pedicles long and slender, more or less hairy. Calyx of 3, 4, or 5 sepals, slightly clothed with a thin silky pubes- cence, and sometimes with a few spreading hairs; sepals taper-pointed, outer ones small, subulate, often wanting. Petals 5, very broad, obcordate, slightly emarginate, imbricate, of a bright yellow, slightly spotted at the base. Stamens numerous. Style scarcely any. Stigma large, capitate, slightly lobed. Capsule villous, 3-valved. Seeds about 15 in each capsule, angular, light brown, warted. Several different species appear to have been con- fused with the present, which is certainly the plant de- cribed in the Hortns Kewensis, and also the one meant by Linnseus, who refers to Miller's figure, which is a good representation of our plant; the spots on the petals are larger and darker than in ours, but we have seen them vary considerably on different plants. We are not so certain of the plant described by M. Decandolle being the same, the peduncles and calyx being described as white and leprous, which was not the case with ours. It is without doubt the H. elongatum of Willdenow's Enumeratio, but it cannot be the H. cheiranthoides of Decandolle, who gives the Cistus elongatus of Vahl, as a synonym with a mark of doubt. It is a native of the South of Europe, and requires protection from severe frost, either in a green-house or frame; the same kind of treatment as is recommended for Cistus ladaniferus and C. candidissimus will suit the present plant. Cuttings of it, planted under hand-glasses on a slight hot-bed, will strike root freely. It may also be raised from seeds, which sometimes ripen.

Leaves alternate or the lower ones opposite, shortly petiolate, hairy, and clothed with a whitish tomentum, and nu- merous fascicles of hairs, rough, the margins somewhat denticulate, variable in form, but all obtuse : lower ones generally opposite, and ovate or obovate; the others al- ternate and oblong or ovate, not so much rounded at the points. Peduncles thickly clothed with little stellate bunches of white hairs, as is also the calyx. Flowers large, solitary, terminating the small branches, pale yellow. Calyx of 5 long taper-pointed sepals, green, or tinged with a purplish brown, very hairy : outer ones narrow, linear, but broadest towards the base ; inner ones ovate, concave inwards, but terminating in a long taper point. Petals 5, obovate or obcordate, narrowing towards the base, distinct or but slightly imbricate. Stamens about thirty, spreading -.filaments bright yellow : pollen orange-coloured. Germen smooth, triangular, ter- minated by a very short style, that is hid by the large capitate stigma. Capsule smooth and glossy, 3-valved, several-seeded. The present beautiful plant is a native of Carolina, and requires to be grown in peat soil ; it should be pre- served through the Winter in frames, or in the Green- house, or it will be liable to be killed in severe frosty weather ; in Winter it dies down to the root, and comes up again the following Spring ; this is the case with all the North American species, by which means they are frequently lost, as the cultivators of them suppose they are quite dead, and turn them out of the pots as such : it is readily increased by young cuttings, planted under hand-glasses in Spring, the young plants to be potted off as soon as sufficiently rooted, that they may be en- abled to become strong enough to stand through the Winter; it may also be raised from seeds, which ripen in abundance.

Petioles very short, hairy. Peduncles one flow- ered, solitary, erect, thickly covered with unequal spread- ing hairs, of a brownish purple colour. Calyx of 5 se- pals, 2 outer ones very small, subulate, very hairy and fringed : inner ones narrowly ovate, taper-pointed, con- cave, very hairy and ciliate, the points tipped with red. Petals 5, obcordate, scarcely crumpled, margins rather uneven, very much imbricate, of a bright yellow colour. Stamens from 20 to 22, spreading flat : filaments un- equal in length, long and slender, bright yellow : pollen dark yellow. Germen smooth and glossy. Style very short, straight, nearly hid by the large capitate stigma. Stigma 3-lobed, papillosely fimbriate. This very pretty herbaceous perennial species is a native of North America, and succeeds best in peat soil, either to be planted in a bed amongst other Ame- rican plants, or to form a patch by itself in a border of the flower garden ; it will also succeed very well in rock- work, but the soil in which it is planted must be chiefly peat, and care must be taken that it is not killed by the drought in Summer. Its handsome flowers are produced in abundance in July and August; after that time it continues to bloom and ripen seeds plentifully until October ; but the flowers after August are all without petals, the calyx and capsules are also smaller and of a different form from those produced by the flowers with petals ; this is also the case with H. polygal&folium and brasiliense, and we expect with the whole of this section. The present plant is sufficiently hardy to endure our Winters in the open air without protection ; but as it dies down to the ground in Winter, many people might sup- pose it was dead, and have it thrown away, particularly when grown in pots, as no signs of life appear in it at that season ; therefore, if grown in pots, they should have the name wrote on labels of some kind, to ensure pre- servation. Seeds of it ripen plentifully ; but they must be gathered as soon as ripe, as the capsule soon bursts, and the seeds are then lost ; the best time for sowing them is early in Spring ; they should be sown in pots, and as soon as up should be pricked out, either sepa- rately or several in one pot, or they will be very liable to damp off if left too long in the seed-pot.

Stigma very large, capitate, papillose. This species is nearly related to H. pplygalafolium, f. 1 1 , but differs sufficiently in the following particulars. The stems of this are more upright and straighter, and clothed with loose wool, not with spreading hairs, as in that ; the leaves in this are broader, and covered all over with long spreading hairs, not glossy on the upper side, and having the hairs in fascicles on the lower side, as in that ; the peduncles here are shorter than the leaves, in that they are double the length of the leaves ; the ca- lyx in this is much longer, with long taper points, and clothed with a close pressed tomentum ; in that it is clothed with bristly hairs ; the flowers in this are larger, the stamens more numerous; the capsule in this is larger and pointed, in that it is nearly globular; the seeds in this are also larger, and the young plants, when first up from seed, may be distinguished apart immedi- ately; they were both sent from the Brazils, by Mr. Fre- derick Sello to Dr. Sims, as two distinct species, one marked Helianthemum, 19, the other 48. Dr. Sims pre- sented the seed to Mr. William Anderson, Curator of the Apothecaries' Company's Garden, at Chelsea, where they were sown in 1823 ; and from a plant raised from it the present drawing was taken last May, the first time that it produced perfect flowers ; those that were produced the preceding Autumn being all apetalous, as are the Autumn flowers of all the species of this section that we have had an opportunity of seeing ; but those apetalous flowers produce as perfect seeds as the com- plete flowers. We have not yet proved whether the Brazilian spe- cies of this genus are hardy enough to bear our Winters in the open air, but at any rate they may be preserved through the Winter in a frame, as we see they are much drawn in a Greenhouse, which proves that it is too warm a temperature for them ; they thrive well in pots in a mixture of sandy loam and peat, and may be raised from cuttings, planted under a hand-glass in Autumn, or from seeds, which ripen in abundance. H. brasiliense of Sprengel, must be a very different species, judging from his description. 11 HELIANTHEMUM polygalsefolium Milkwort-leaved Sun-Rose. Sect. II. LECHEOIDES.

Perennial. Stems several from the same root, elon- gated, very much branched, suffruticose, flexuose, slender, branching in various directions, ascending : branches thickly clothed with a kind of villous tomen- tum, and a few hairs intermixed. Leaves on the branches, without stipules, alternate, sessile, acute, hairy on both sides, fringed, of a dark glossy green on the upper side, and paler underneath ; channelled on the upper side, the under side covered with tufts of starry hairs and longer ones intermixed : lower leaves oblongly-lanceolate, upper ones narrower, lanceolately linear, acute, concave. Peduncles 1-flowered, opposite to a leaf, and longer than the leaves, clothed with numerous fascicles of starry canescent hairs, and a few longer ones intermixed. Calyx of 5 sepals, the 2 outer ones very small, linear, bluntish, setosely hairy, inner ones ovately-lanceolate, taper-pointed, the points tipped with red ; the inner margin scariose and membrana- ceous, thickly clothed with rather decumbent bristly hairs. Petals 5, or sometimes 6, broadly obovate or obcordate, slightly notched, concave, slightly imbricate at the base, of a bright yellow. Stamens about 24, unequal in length, spreading : filaments smooth, pale yellow, overtopping the stigma : pollen orange- coloured. Germen smooth. Style straight, very short. Stigma very large, capitate, papillose. Had we not seen H. brasiliense growing by the side of the present plant, we should have been inclined to have given it for that species, as the description given of that by M. Decandolle differs but little from our present subject, but it still agrees better with what we consider the true H. brasiliense ; plants of both species were raised from seed, the year before last, by Mr. An- derson, at the Apothecaries' Company's garden, at Chelsea, where our drawing was made last July ; the seeds were given to him by Dr. J. Sims, who received them from Mr. Frederick Sello, by whom they were col- lected in the Brazils, and Mr. Anderson informs us that they are the best things he has yet sent ; the present plant differs from H. brasiliense in being much more smooth and slender, its branches are more decumbent, the leaves less pubescent, of a glossy green, and narrower, and the capsules scarcely half the size ; we have not seen any perfect flowers of H. brasiliense, as it did not bloom till autumn, and the flowers were all apetalous, which was also the case with the autumn flowers of the present species, and all the other species of this section that we have had an opportunity of ex- amining this season ; the apetalous flowers all produce perfect seeds, but we do not understand the reason of their producing perfect flowers only in summer. This plant, as well as H. brasiliense, will require to be kept in a cool part of the Greenhouse, or in frames, in frosty weather, or they will be liable to be injured, though perhaps they will prove quite hardy, as we ob- serve they draw up very weak in the Greenhouse ; they thrive well in a mixture of turfy loam, peat, and sand; and young cuttings taken off at a joint, and planted under hand-glasses, will soon strike root ; plants may also be raised from seeds. 20. 110 HELIANTHEMUM glomeratum.

Stem suffrutescent, erect, much branched : branches erect, flexuose, densely clothed with short hairs, and white down underneath, forked at the points, and branch- ing again in all directions. Leaves alternate, sessile, or on very short pedicles, deciduous or dropping off in Winter, oblong, the lower ones largest and nearly ovate, obtuse, the upper ones lanceolate and more acute, all attenu- ated towards the base, hoary on both sides, but whitest underneath, thickly clothed on both sides with tufts of short hairs, that are seated on little tubercles, which causes a roughness on the leaf when examined with a lens. Petioles very short, furrowed a little on the upper side and rounded below, densely pubescent. Flowers numerous, crowded in dense clusters in the axils of the leaves, and terminal, so as to appear like an interrupted spike or raceme; in our plant always apetalous, nearly sessile, or on very short footstalks. Calyx of 5 sepals, densely clothed with short hairs that are seated on mi- nute tubercles, of a hoary appearance : two outer ones very small, spreading; the three inner ones ovate, acute, concave. Capsule 3-sided, 3-celled, smooth and glossy. Seeds few, small, somewhat flattened on one side and convex on the other, of a yellowish brown colour. This curious little plant is a native of Mexico, and was raised from seed brought from that country by Mr. Bullock, who parted with them to Mr. Tate, of the Sloane Street Nursery, and from a plant raised by him, the present figure was made : like all the other American species that we have yet seen or heard of, it belongs to the section Lecheoides of Decandolle : all the species of which produce flowers with petals, in the Spring and early in Summer, whereas all those that are produced in Autumn,which are much more numerous, are all ape- talous : the present plant has never produced its Spring flowers with us, most probably by being killed back a good way in Winter, so that it has had to make new shoots for flowering, and those have always produced their flowers in Autumn for three years following, they have all been apetalous like those in our figure, but have ripened seeds annually : if the plant was kept in an airy part of the Greenhouse in Winter, or in the window of a light room, so that its shoots might not be killed back, it would most probably bear plenty of perfect flowers in Spring, the same as H.polygaksfolium, H. brasiliense, H. carolinianum, and the other American species ; it grows freely in an equal mixture of turfy loam, peat, and sand ; and young cuttings, planted under hand-glasses, in Spring, root readily ; they may also be raised from seeds. 46. 46 HELIANTHEMUM lignosum Hard-wooded Sun- Rose.

Stem shrubby, erect, very hard and ligneous, branch- ing, clothed with a hard brown rugged scaly bark, sometimes cracking longitudinally, obtusely 4-sided, here and there knotted where the branches have died away : branches ascending, soon becoming hard and woody, and appearing rugged from the persistent bases of the decayed leaves, clothed with long bristly hairs. Leaves crowded, opposite, oblongly ovate, acute, atte- nuated at the base down the petiole, strongly 3-nerved underneath, and deeply 3-channelled on the upper side, clothed underneath with a dense white tomentum, and the nerves with long spreading, white hairs ; upper side very rough when rubbed backward, and densely covered with canescent decumbent bristly hairs, and short down intermixed. Flowering branches ascend- ing, densely clothed with long villous hairs on the lower part, the upper part smooth, and slightly glau- cous : leaves on the lower part opposite, sessile, ovately oblong, smooth on the upper side, and hairy under- neath : upper ones alternate, sessile, glaucous, smooth, N2 elliptic, concave, acute. Racemes terminal, sometimes panicled, few-flowered. Bractes oblongly lanceolate, concave, acute, keeled at the back, smooth and glau- cous. Pedicles smooth, about the length of the calyx, more or less tinged with red, not transparent, and 3 times the length of the calyx as in H. tuberaria, nodding before flowering, erect when in bloom, after- wards reflexed. Calyx of 5 sepals, which are smooth and glaucous, 2 outer ones very small, subulate ; the inner ones broadly ovate, concave, acute, tipped with red, their margins scariose and membranaceous. Pe- tals 5, obovate, with rounded points, distinct or slightly imbricate at the base, much spreading. Sta- mens from 40 to 50, spreading, the outer ones shortest : filaments smooth and slender, pale yellow : pollen orange-coloured. Germen downy. Style very short, hid by the large stigma. Stigma capitate, granular. Our drawing of this curious plant was made from one at the Garden belonging to the Apothecaries' Com- pany at Chelsea, where it was first raised from seeds given to Mr. Anderson by Mr. George Don, who in- forms us that it was cultivated in his father's garden at Forfar, a great many years back, as H. tuber aria, but he is not certain from whence he first obtained his seeds : it is rather tender, requiring the protection of a frame or Greenhouse in Winter, succeeding well in a mixture of sandy loam and peat, and is readily in- creased by seeds, which ripen plentifully. 18 HELIANTHEMUM Tuberaria.

Perennial, herbaceous, branching round in all direc tions : branches short, very hairy at the base : flowering- ones lengthening out, ascending, quite smooth, of a pale glaucous green. Leaves near the root opposite, oblongly-ovate, obtuse, attenuated at the base and down the petiole, strongly 3-nerved underneath, and furrowed with 3 deep channels on the upper side, slightly ca- nescent, clothed underneath with a short white toraen- tum, the nerves very hairy: upper side hairy and rough, the hairs decumbent, and the roughness occa- sioned by innumerable minute warts that are scattered all over the surface. Petioles deeply channelled on the F2 upper side, and keeled on the lower, furrowed on each side, thickly clothed with bristly hairs : leaves on the flowering stems sessile, smooth and glaucous, more acute, concave, lower ones opposite, the upper ones al- ternate.

Stamens about 50, inner ones overtopping the stigma, outer ones much shorter : filaments smooth, light yellow : pollen orange-coloured. Germen downy. Style very short, scarcely any. Stigma large, capitate, granular. A handsome herbaceous perennial plant, which suc- ceeds best in rock- work in sandy soil ; as it is a native of the South of Europe, it is rather tender, and should be planted in a southern aspect, but it will suffer more from too much moisture than from cold, for if planted out in the common borders it thrives well all the Sum- mer, but will seldom survive the Winter, as its roots get rotten with too much wet. Plants of it grown in pots, and kept in frames through the Winter, may be turned out in the borders in Spring, where they will flower profusely, and will ripen their seeds ; they succeed well in an equal mixture of turfy loam and peat, or any other light sandy soil, and are increased freely by seeds, which ripen in abundance. Our drawing was taken from a plant that we received from the Nursery of Mr. Joseph Knight, last Summer. We have a drawing of a very curious nearly related species, but quite shrubby, and of a hard woody tex- ture, which we received from the collection at the Apo- thecaries' Company's Garden at Chelsea. 30 HELIANTHEMUM eriocaulon.

Stigma headed, fimbriate. Capsule 3-celled, many-seeded. This pretty little annual plant is a native of Spain, Italy, and other countries in the South of Europe. It only requires to be sown in the open borders of the Flower Garden, and to be kept free from weeds ; the seeds should be sown in March, or the beginning of April ; the plants will then flower abundantly, and ripen plenty of seeds.

Stipules very small, linear, very hairy, spreading. Racemes several-flowered, secund. Flowers sessile, or the lower ones on very short footstalks, all facing one way, pale yellow or straw-coloured. Peduncles densely clothed with woolly hairs. Bractes generally alternate with the flowers, deciduous. Pedicles very short, and only on the lower flowers. Calyx of 5 sepals, large, in- flated, very hairy : two outer sepals very small, spread- ing, and clothed with spreading hairs: inner ones broadly ovate, three to five-nerved, glossy, the nerves pale red, hollow on the inside.

Style a little twisted at the base, then be- coming erect. Stigma capitate, papillose. This pretty little species is a native of Barbary, Egypt, and the Levant, and is therefore rather tender, requiring to be kept in frames, or in the Greenhouse, in severe frosty weather ; or if planted in rock- work, a common garden-pot placed close over it, with the hole at the bottom close stopped, will protect it very well ; we find this method succeed with many plants that are tender, such as the herbaceous plants from Mexico, Chili, Peru, The Cape of Good Hope, New South Wales, the Levant, and the Canary Islands ; and nu- merous rather tender plants that would otherwise be killed, are preserved in good health, by that means ; the best soil for the present species is a mixture of light sandy loam and peat; and some plants of it should be grown in pots, and preserved in frames or in the Green- house, in Winter, or in the window of a light room ; young cuttings, planted under hand-glasses in Summer, in a shady situation, will root freely ; it also produces an abundance of seeds, by which young plants may be readily raised. Our drawing was made from a plant in the Garden belonging to the Apothecaries' Company, at Chelsea, where it was raised from seeds by Mr. W. Anderson. 16 HELIANTHEMUM Fumana, Heath-like Sun-Rose.

Stipules and Bractes none. Pe- duncle solitary, 1 -flowered, either terminal, or opposite to a leaf by the side of the branch, longer than the leaf, densely clothed with short woolly hairs, and a few longer ones intermixed, erect before flowering and when in bloom, afterwards reflexed. Calyx of 5 sepals, thickly clothed with short hairs, and some longer ones intermixed, twisted at the point before expansion; 2 outer sepals oblong, obtuse, scarcely half the length of the inner ones ; inner ones ovate, concave, tapering at the point, strongly 4-nerved, the margins scariose and membranaceous. Petals 5, roundly ovate, slightly imbricate at the base, the points distinct and spread- ing, of a bright yellow colour. Stamens about 16 bearing anthers, besides several sterile ones : filaments smooth, pale yellow, the sterile ones rather shortest and spreading : pollen bright yellow. Germen smooth and glossy. Style a little bent at the base, thickening upwards, about the length of the stamens. Stigma capitate, slightly 3-lobed, fimbriate. This curious little plant is a native of the South of Europe, and is a very proper subject for the ornament- ing of rock- work, but it should be planted on the south side, as it is rather tender, and if the Winter prove severe, it will need a little covering ; it also makes a pretty appearance when grown in small pots, and it can then be protected in a frame in severe weather, but it must be exposed to the air as much as possible in fine weather, as it is very apt to get damp and mouldy if shut up too close. It succeeds well in an equal mixture of sandy loam and peat, and is readily raised from seeds, which ripen in abundance. The present plant is often confused with H. procum- bens, but is readily distinguished when both are grow- ing together ; plants of that species were shown us by Mr. Anderson, of the Chelsea Botanic Garden, but they did not flower last Summer. Our drawing was taken at the Nursery of Mr. Colvill, in July last. iff 68 HELIANTHEMUM procumbens. Procumbent Sun-Rose. Sect. VII. FUMANA. Suprafol. 16* * Foliis altcrnis exstipulatis.

Peduncle short, axillary, solitary, purplish, slightly pubescent, erect when in bud, and when the flower is expanded, afterwards reflexed. Calyx of 5 sepals, twisted at the point before expansion, 2 outer ones narrow, linear, acute, more than half the length of the inner ones, which are ovate, concave, taper-pointed, 3 or 4-nerved, the nerves purplish, tubercled, and clothed with very short hairs. Petals 5, broadly obo- vate, imbricate, of a bright yellow. Stamens about 20 bearing anthers, besides a few sterile ones : filaments smooth, pale yellow. Germen glossy, slightly pubes- cent. Style smooth, a little bent at the base, thickening upwards. Stigma capitate, fimbriate, slightly 3-lobed. This pretty little plant is nearly related to H. Fu- tnana, but is readily distinguished by its more procum- bent habit, more loosely spreading leaves, and parti- cularly by its seeds, which remain several days in the capsule after it is burst, whereas in H. Fumana they spring out immediately as soon as the capsules open, so that it is very difficult to procure them, except by gathering them before they are quite ripe. Our drawing was made from a plant in the fine col- lection belonging to the Apothecaries' Company, at Chelsea, where it was raised from seed by Mr. W. An- derson ; it is a native of the South of France, Italy, and Tauria, according to M. Decandolle ; and we find it much hardier than H. Fumana, thriving well in a light sandy boil, or a mixture of light turfy loam, peat, and sand, will suit it very well. It makes a pretty plant mixed with others, for adorning rock- work, but will require a little covering in severe frosty weather; or it may be grown in small pots, and can then be pro- tected in frames or in the Greenhouse, in Winter. Seeds of it ripen plentifully, by which it might be readily increased ; or cuttings, planted under hand- glasses, will soon strike root. 9T HELIANTHEMUM arabicum Arabian Sun- Rose. Sect. VII. FUMANA.

Suffrutescent, very much branched : branches slender, hairy, ascending, growing in a close compact tuft. Leaves alternate, linearly oblong, taper-pointed, attenu- ated to the base, nearly sessile, hairy. Petioles very short, or scarcely any. Stipules ovate, taper-pointed, hairy, and fringed. Peduncles solitary, opposite to a leaf, or termi- nating the branches, twice the length of the calyx, slen- der, and clothed with short hairs. Flowers saffron-co- loured, more or less tinged with purple at the back and margins. Calyx of 5 sepals, thickly clothed with short hairs; the two outer ones smallest, lanceolate, broad- est towards the base, taper-pointed, spreading, or the points sometimes reflexed : inner ones ovate, acute, con- cave inwards, 2 or 3-nerved. Petals^, broadly obovate, terminating in a sort of point, very much imbricate at the margins. Stamens numerous : filaments smooth, yel- low, unequal in length. Germen pubescent. Style smooth, longer than the stamens. Stigma small, capitate, papil- 2 c lose. Capsule large, pubescent, three-celled, and many seeded. The present handsome and very distinct species is a native of Barbary, Arabia, Greece, and the South of Europe, and is therefore rather tender, requiring the protection of a frame or Greenhouse in Winter ; or if grown by the side of a wall, or in rock-work, it will need some sort of covering in severe frosty weather ; but it is much better to preserve some plants of it in pots in the Greenhouse or frames through the Winter, keeping them in an airy situation, and exposing them as much as possible in mild weather, that they may not be drawn up weak ; they can then be turned out in the Spring, and be planted in rock- work, or in a warm bor- der, where they will produce their lively flowers in suc- cession for a considerable time; young cuttings, plant- ed under hand-glasses in Spring or Summer, will strike root readily. 24. 24 HELIANTHEMUM Isevipes.

Stem shrubby, very much branched, ascending : branches very slender, rigid and easily broken. Leaves alternate, stipulate, bristle-shaped, nearly cylindrical, obtuse, with a short sharp point, succulent, of a very blue glaucous colour. Stipules subulate, acute, not half the length of the leaves : in the axil of each large leaf is a tuft of smaller ones, which belongs to a young shoot, but many of which never come to perfection. Peduncles ter- minal, racemose, often panicled, villosely hairy, at first nodding, but as the flowers expand, considerably lengthened and becoming straight. Bractes at the base of the pedicles, and alternating with them, obtuse, broadish at the base, the lowermost largest and gradually decreasing upwards. Pedicles quite smooth, purplish, all leaning to one side, nodding before the flowers ex- pand, erect when in bloom, afterwards reflexed. Calyx of 5 sepals, a little twisted before opening ; 2 outer ones roundly oblong, blunt, hairy, and fringed : inner ones ovate, scarcely acute, concave, strongly 4-nerved, with scariose membranaceous margins, very hairy. Corolla of 5 petals, distinct or scarcely imbricate, roundly obo- vate or obcordate, slightly concave, more or less cre- nulate, of a bright pale yellow. Stamens numerous, about the length of the style, scarcely half of them bear- ing anthers : filaments slender, pale yellow, more or less twisted, about 20 bearing anthers, sterile ones sur- rounding the fertile ones, slender and more twisted, having the appearance of fringe : pollen pale yellow. Germen smooth. Style a little bent at the base, scarcely thickening upwards. Stigma small, capitate, slightly 3-lobed, fimbriate. This elegant little plant is a native of the South of Europe, and requires the protection of a Greenhouse in Winter ; but the more airy the situation is, in which it is grown, the better it will thrive, as it is liable to damp and lose its leaves if grown in too close a situation, or crowded amongst other plants ; its flowers are produced from June to August, according to the situation in which it is kept ; they are of short duration, as the stamens so soon come in contact with the stigma, which fertilizes the capsule, and the petals are thrown off immediately ; but this may be prevented in part, by taking off the an- thers before they burst, the petals then remain on much longer ; the same rule is applicable to all other flowers, many of which may be preserved for days or even weeks longer, by divesting them of their anthers, and keeping them in a close house where no insects can bring pollen to them; we have known this circumstance for years, but we do not know that it has ever been published ; we first observed it when we were attaching the pollen of the different species of Pelargonium to the stigmas, the petals were almost immediately thrown off, whereas others of the same sorts remained in flower many days, in a house that was kept shut up from the insects, and where the pollen was not applied to the stigmas. The present little plant succeeds well in a mixture of sandy loam and peat, and is readily increased by seeds, which should be sown early in Spring ; or by cuttings, which strike root freely under hand-glasses.

Leaves crowded, opposite, linearly oblong, scarcely acute, very short, thickly clothed with a roughish pubescence ; the young shoots produced in the axils of the leaves give the ap- pearance of the leaves being tufted : upper leaves some- times alternate. Stipules short, erect, mucronate. Ra- cemes terminal, few-flowered, nodding before the flowers expansion, becoming erect as they expand. Peduncles and pedicles villosely hairy, somewhat glutinous. Brae- tes short, very hairy. Pedicles drooping before the flow- ers expansion, erect when in bloom, afterwards reflexed. Calyx of 5 sepals, clothed with a short clammy pubes- cence; the 2 outer ones very small and narrow, spread- ing or somewhat reflexed, inner ones broadly ovate, concave, short and inflated, acute. Petals 5, bright yellow, obovate, somewhat crumpled, imbricate over 2 D2 each other near the base. Stamens from 20 to 30 : jila- ments pale yellow. Germen smooth, 3-sided. Style straight, smooth, a little longer than the stamens. Stig- ma capitate, slightly 3-lobed, fimbriate. This neat little species is a native of the South of Europe and the Levant ; it is an old inhabitant of our gardens, in which it is sometimes in great abundance ; but is again frequently lost, as it is very apt to rot off in Winter with too much moisture, as well as from se- vere frost ; it is therefore best to keep some plants of it in pots, to be preserved in frames or in the Greenhouse in frosty or very wet weather, exposing it as much as possible when the weather is dry and mild ; although its flowers are not so showy as some other species, its very distinct habit and character make it well worth the notice of cultivators, particularly as it belongs to a tribe of the genus that produces but few species : the best soil to grow it in is a sandy peat, mixed with a little loam, and the pots to be well drained with pot- sherds, that the wet may pass off freely : young cut- tings, planted under hand-glasses, in a light sandy soil, in Spring or Autumn, will soon strike root; it may also be raised from seeds, which are ripened in abun- dance ; plants of it make a pretty appearance in Sum- mer when planted out in rock-work, but they will sel- dom survive the Winter in such situations, without be- ing well attended to, and covered up in severe weather, and to be exposed as much as possible when the weather is mild. 83 HELIANTHEMUM glutinosum Clammy Sun-Rose.

Leaves opposite on the lower part of the stem, the upper ones alternate, linear or sometimes lanceolately linear, revolute at the margins, thickly clothed with short viscous hairs, of a dark green colour, but they appear rather hoary from the hairs with which they are covered, upper ones shor- ter and blunter. Petioles very short. Stipules on the lower leaves small, subulate, fleshy, pubescent : on the upper ones longer and larger, spreading, and bluntish, villous. Flowers axillary, solitary, terminating the bran- ches in a sort of raceme, that is at first a little nodding, but as the flowers expand, it becomes upright. Pedicles villosely viscous. Calyx of 5 sepals, clothed with short viscous hairs ; the two outer ones very small, oblong, bluntish: inner ones ovate, concave, strongly veined, scarcely acute.

Stamens several : filaments smooth , pale yellow. Germen glossy, 3-sided. Style straight, smooth. Stigma capitate, fimbriate, slightly 3-lobed. The present very distinct species is a native of Spain, and the South of France, and requires a little protection in Winter, either to be placed in a frame or the Green- house in frosty weather ; its flowers are very fugacious, as the petals stay on but a few hours in the morning, and are always fallen before the middle of the day, but the flowers are produced in succession nearly all the Summer and till late in Autumn ; it also ripens abund- ance of seeds ; the best soil to grow it in is an equal por- tion of sandy loam and peat ; and if grown in rock- work, it will require a little covering in Winter. Cuttings of it, planted in pots, or under hand-glasses, in July or August, will soon strike root. Our drawing was made from a plant sent us by A. B. Lambert, Esq. from his choice collection at Boyton House, Wilts, where it was raised from seed received from Spain. 85 HELIANTHEMUM oelandicum. Pale green-leaved Sun- Rose. Sect. VIII. PSEUDOCISTUS.

Our drawing of this pretty little species was made from a plant in the Apothecaries' Company's Garden at Chelsea, several plants of it having been raised by Mr. W. Anderson, from seeds that he received from Germany ; it is nearly related to H. alpestre, but is suf- ficiently distinguished by its weaker growth, much narrower leaves, and smaller flowers, the petals of which are distinct, and not imbricate as in H. alpestre. It is a very pretty plant for the ornamenting of rock- work, taking up but little room, so that it requires to be planted in a conspicuous situation; it also does very well, and makes a pretty appearance, when culti- vated in small pots, requiring a light sandy soil ; young cuttings of it, planted under hand-glasses, strike root readily ; it may also be increased by seeds, which should be sown the beginning of April, and as soon as up, be pricked off in small pots, and as they increase in size to be shifted into larger ones, they will then make fine plants the first season. 74 HELIANTHEMUM pulchellum.

Leaves nearly round, or the upper ones ovate, the mar- gins slightly revolute ; lower ones very small, green, and dotted with little rough dots on the upper side, and covered with stiffish white hairs, underneath clothed with a dense white tomentum. Petioles short and flat, fringed with long hairs. Racemes terminal, simple, several-flowered, nodding before the flowers ex- pansion, afterwards erect. Bractes lanceolate, acute, broad at the base, very hairy. Pedicles slender, clothed with a short white thin tomentum, and a few longer hairs intermixed, nodding before the flowers expand, and erect when in bloom, afterwards reflexed. Calyx of 5 sepals, clothed with long bristly hairs, which give it a white appearance ; 2 outer sepals very small, lance- olate, bluntish ; inner ones ovate, obtuse, concave, strongly nerved. Petals 5, broadly obcordate, imbri- cate, slightly crenulate, of a bright pale yellow. Stamens from 40 to 50, the filaments and anthers yellow. Ova- rium pubescent. Style short, twisted. Stigma very large, capitate, fimbriate. From Sprengel's description, we believe the present to be the plant he intends for H. alpestre, but certainly not the one described by Decandolle, which we have already published, and the leaves of which are green on both sides ; the present is a stiffer shorter plant, with much stiffer and rounder leaves, which are of a snowy whiteness on the lower side. It is certainly a very pretty plant when covered with its numerous flowers, and is a very proper subject for adorning rock-work, or for growing in a small pot ; it is quite hardy, as we see several nice plants of it thriving well in Mr. Col- vill's Nursery at Roehampton, that had stood two years in the open border without any protection. It succeeds well in a light sandy soil, or an equal mixture of light sandy loam and peat will suit it very well ; young cut- tings, planted under hand-glasses, in Autumn, strike root readily. Our drawing was made last Summer, from a plant in the collection of Mr. Colvill, at his Nursery in the King's-road, Chelsea. 2 HELIANTHEMUM alpestre. Alpine Sun- Rose. HELIANTHEMUM.

An elegant little species, well adapted for the orna- menting of rock-work, or for growing at the front of flower borders, where its lively blossoms, which con- tinue in succession for a considerable time, make a handsome appearance. It is a native of various parts of Europe, growing in rocky mountainous situations ; we have compared our plant with a fine specimen in Mr. Lambert's Herbarium, with which it agrees so exact, that the drawing might be supposed to have been made from the very specimen. It succeeds well in small pots, planted in a mixture of light sandy loam and peat; and cuttings strike root readily, taken off in the young wood as soon as ripened, and planted under hand-glasses, where they will soon strike root; it may also be raised from seeds, which sometimes ripen.

Petals 5, distinct, spreading, longer than the sepals, yellow, narrow at the base and broad at the points. Stamens about 40, spreading. Ovarium trian- gular, with thick margins, pubescent. Style twisted round. Stigma capitate. Capsule 3-celled, with two or three seeds in each cell. A pretty trailing dwarf suffrutescent plant, the bran- ches very slender, and extending to a good distance round, so that it is very desirable for ornamenting rock-work, as it is covered with flowers a great part of the Summer; after flowering, a great part of its leaves become quite white and silvery on both sides ; and we are not acquainted with any species that varies so much in the colour of its leaves at various seasons. Accord- ing to Decandolle, it is a native of Germany, Switzer- land, France, and Spain, so that it is quite hardy, or only wants the least protection in severe frost, thriving well in a mixture of light sandy loam and peat, or any other light sandy soil, succeeding best in rock- work, or to be grown in small pots ; for if planted in the open ground, it will be liable to suffer with too much mois- ture in Winter. Cuttings root readily, planted under hand-glasses, or it may be raised from seeds, which ripen plentifully. Our drawing was made from plants, in the Garden belonging to the Apothecaries' Company, at Chelsea, where they were raised by Mr. Anderson from seeds received from Germany. 56 HELIANTHEMUM canum.

Stems shrubby, procumbent, or sometimes nearly up- right, very rough and rugged : branches numerous, sim- ple or rarely branched, erect or nearly so, when culti- vated in a pot or in poor gravelly soil ; but in richer soil the branches are very long, procumbent, their points ascending, and spreading round to a great distance in all directions, densely clothed with a white woolly pu- bescence. Leaves of a silky appearance, densely clothed with a white starry pubescence, of a greyish white un- derneath and of a glaucous colour on the upper side, margins slightly revolute ; the small lower leaves nearly orbicular or rounded, the middle ones elliptic or ob- long, obtuse ; upper ones nearly lanceolate and more acute. Petioles short, stellately pubescent, the pubes- cence close-pressed. Stipules linear, linearly-oblong qr lanceolate, of a greenish colour, clothed with spreading villous hairs, the margins more or less fringed, and the points tipped with bristly hairs, lower ones very small, upper ones elongated. Racemes terminal, 3 to 7-flower- ed, curved inwards before flowering, afterwards becom- ing erect. Bractes linearly oblong, nearly as long as the pedicles, villous, of a green colour. Pedicles densely ca- nescent, nodding before flowering, erect when in flower, and reflexed after flowering. Calyx of a yellow, glaucous colour, minutely pubescent. Sepals 5, the 2 outer ones very small, oblong, blunt, of a greener colour : inner ones ovate, concave, obtuse, membranaceous, strongly 4-ner- ved, the nerves more or less hairy. Petals 5, large, much imbricate, more or less crumpled, obcordate, of a bright saffron-colour at the base, and the upper part of a glossy yellow. Stamens 40 to 50: filaments long and slender, straw-coloured : pollen bright yellow. Germen densely tomentose. Style smooth, slender at the base and thick- ened upwards, curved round at the bottom. Stigma ca- pitate, papillose. Our drawing was made from an unusually strong plant, growing in the rock- work of the garden belong- ing to the Apothecaries' Company, at Chelsea, where it covered more than the space of a yard in diameter, and made a grand appearance when covered with flowers. It is a native of Barbary, and the South of Europe, and is all the better for a slight covering in severe frosty weather, though it will succeed well through a mild Win- ter without the least protection . We have seen specimens of it in Mr. Lambert's Herbarium, that were marked by Dunal himself, so that we are certain of ours being his species. It succeeds well in any light sandy soil, and may be grown in rock- work or in any tolerable dry situation, where it will flower better than if kept in pots, though it is well to preserve a few in pots, which can be kept in frames or some place under cover in severe frosty weather. Young cuttings, planted under hand-glasses, from July to September, will strike root readily. Ill a>i,JA?0- Ill HELIANTHEMUM glaucum Glaucous-leaved Sun-Rose. Sect. IX. EUHELIANTHEMUM.

Style bent a little at the base, shor- ter than the stamens. Stigma capitate. For the opportunity of giving a figure of this pretty species, we are obliged to Robert Barclay, Esq. from whose collection, at Bury Hill, fine specimens, in full flower, were sent us in August last ; this is the only collection in which we have seen it for some time ; for being a native of the South of Europe, it is very liable to be killed in severe Winters, if it be not a little protected ; a common garden pot, placed over the plant, or the co- vering of a mat, or a little dry litter, in severe frost, will protect it very well, giving it free access to the air in mild weather, that it may not be drawn up tender ; a mixture of light sandy loam and peat suits it very well ; and a few plants should be kept in pots, to be preserved in frames, or in the greenhouse in Winter ; they can then be turned out, and planted in the borders, or in rock-work, in Spring ; a few plants of each sort might also be kept continually in pots, as nothing can make a more brilliant and neat appearance, than a collection of the different sorts grown in pots, and standing toge- ther in a close mass ; the branches, as they spread over the pots, and are all covered with bloom, make a very splendid appearance ; and although the flowers drop every evening, they are succeeded by others for a length of time ; and if cut off as soon as overblown, the young shoots that spring forth will be again covered with bloom, which will continue till late in Autumn ; young cuttings, planted under hand-glasses, in Spring or Autumn, will soon strike root ; young plants may also be raised from seeds. 20 HELIANTHEMUM leptophyllum Narrow-leaved Sun- Rose.

Stem shrubby, hard and woody at the base, ascend- ing or procumbent, clothed with a rugged brown bark, much branched : branches spreading in various direc- tions, ascending, slender, clothed with a loose grey tomentum. Leaves opposite, the upper one often al- ternate, narrow, oblongly linear, bluntish, attenuated at the base into a short petiole, the margins much rolled back, underneath strongly nerved, and clothed with a short dense grey tomentum ; the upper side channelled, of a dark glossy green and slightly pubes- cent, the points tipped with short hairs. Stipules small, subulate, hairy, scarcely longer than the petioles, and tipped with a fascicle of short bristle like hairs. Ra- cemes long and loose, many-flowered, nodding before expansion, afterwards becoming erect. Sractes small, linear or lanceolate, hairy and fringed. Peduncles red- dish brown, woolly, nodding before expansion, erect when in flower, and reflexed when in fruit. Calyx of 5 sepals, the 2 outer ones very small, lanceolate, con- cave, ciliate and tipped with bristle like hairs : 3 inner ones ovate, concave, strongly 4-nerved, with membra- naceous margins, the nerves warted with brown warts, and villosely hairy. Petals 5, imbricate, broadly obo- vate, the edges undulate and slightly crenulate, of a light yellow, with a saffron coloured crescent shaped mark near the base. Stamens about 40, rather shorter than the style ; filaments slender, smooth, pale yellow. Germen silky. Style twisted at the base, oblique, slen- der at the base, and thickened upwards. Stigma capi- tate, papillosely fimbriate. Our drawing of this plant was taken from one obli- gingly communicated to us by Mr. Anderson, from the Chelsea Botanic Garden, last September, when it was in full bloom for the second time that Summer, the dry weather setting in at the season that they were in bloom the first time, which made the blossoms soon drop, and when the wet set in, they produced fresh blooming- shoots ; and many of the species were flowering again in Autumn as fine as in the Spring. Mr. Anderson had received this species under the name of H. st&cha- difolium, which, as M. Decandolle remarks, is the gar- den name for it ; he also had it from Mr. Webb, under the name of H. BarreUeri, under which name it is figured in the Botanical Magazine, on Mr. Webb's au- thority ; but it is very different from H. Barrelieri of Decandolle and Tenore ; that species belongs to quite a different section : we showed our drawing to M. La- gasca, who immediately recognized it as his H. angusti- folium, which is the synonym given by M. Decandolle. It is a native of Spain and the South of Europe, and succeeds well on rock- work, in a sheltered situation ; or it will thrive well in pots, in an equal mixture of sandy loam and peat; cuttings root readily planted under hand-glasses in Autumn ; it may also be raised from seeds, which are sometimes ripened. 60. 60 HELIANTHEMUM serpyllifolium.

Stem suffruticose, procumbent, very much branched : branches crowded, spreading round in all directions, the points ascending, smooth and glossy on the lower part, and warted here and there, the upper part slightly hairy on the young shoots. Leaves opposite, crowded, generally distichously spreading and imbricate, flat, or the margins slightly revolute, underneath clothed with a dense white tomentum, the upper side smooth, of a glossy green, hairy while young, the margins more or less fringed with rather distant hairs, which are some- times singly, and sometimes in small tufts : lower leaves, and those on the small branches, roundly oval, blunt- ish : upper ones, and those on the long shoots, oblongly elliptic, or elliptically lanceolate, more acute. Petioles shorter than the stipules, slightly pubescent. Stipules green, linear, acute, very much fringed with long bristly hairs. Racemes terminal, several-flowered, nodding be- fore the expansion of the flowers, afterwards lengthen- ing out and erect. Bractes linear, resembling the sti- pules, also very much fringed. Pedicles downy, nod- ding before expansion, nearly erect when in bloom, afterwards reflexed. Calyx of 5 sepals, the 2 outer ones very small, oblongly linear, bluntish, much fringed with bristly hairs, the three inner ones slightly pubes- cent, elliptically lanceolate, concave, acute, transparent and membranaceous, strongly 4-nerved, the nerves green, and thinly clothed with hairs, the points also tipped with hairs. Petals 5, distinct, very much spread- ing, not at all imbricate, obovate, very narrow at the base, of a bright yellow colour, with an elegant orange coloured circle near the base. Stamens about 70 ; fila- ments long and slender, about the length of the style, pale yellow. Germen clothed with silky hairs. Style nearly straight, smooth, thickening upwards. Stigma capitate, papillose. The present species is readily distinguished from all others by its leaves growing in a distichous form. It is a native of Somersetshire, we having discovered it there in the Autumn of 1826, when we visited that part; we observed it in a bye-lane, leading from Failand-hill to the Farm of Mr. J. Mattocks, of Honour, near Port- bury, and no other sort grew there ; we have been since informed by Mr.T. Harding, Gardener to the Rev. F. Bea- don, of North Stoneham, Hants, to whom we showed our figure, that he also observed it near Wells, in Somer- setshire, where he was immediately struck with it as a distinct species; it is quite hardy, and is a very pretty plant for decorating rock-work, thriving well in any light sandy soil. Cuttings of it root readily, planted un- der hand-glasses, the latter end of Summer or Autumn. Our drawing was made at the Nursery of Mr. Colvill, of the KingVroad, Chelsea. 34 HELIANTHEMUM vulgare Common Sun- Rose. Sect. IX. EUHELIANTHEMUM. Supra, fol. 7. * Petalis luteis.

Stems suffruticose, procumbent, very much branched : branches spreading in all directions, ascending, elon- gated, slightly hairy, the upper part clothed with a hoary tomentum . Leaves very variable, petiolate ; lower ones nearly round or broadly ovate, and bluntly round- ed : middle ones ovately elliptic or oblong ; upper ones elongated, oblong, or lanceolate, acute, slightly revo- lute at the margins, upper side green and hairy, and punctated with numerous minute dots, which occa- sions a roughness, underneath clothed with a close- pressed dense white tomentum : the margins more or less ciliate. Petioles slender, clothed with close-pressed hairs. Stipules leaf-like, linearly lanceolate, acute, hairy and fringed, sometimes about the length of the petioles and sometimes double the length, upper ones longest and broadest. Racemes terminal, loose, many -flowered, nodding and involute before the expansion of the flow- ers, afterwards becoming erect. Bractes lanceolate, shorter than the stipules, hairy and fringed, from half to one-third the length of the pedicles. Pedicles clothed K 2 with a short white tomentum and a few hairs inter- mixed, nodding before the flowers expand, erect when in bloom, afterwards reflexed . Calyx of 5 sepals ; the two outer ones small, oblong or ovate, obtuse, very hairy and fringed ; 3 inner ones ovately lanceolate, acute, concave inwards, membranaceous, strongly 4-nerved, the nerves very hairy. Petals 5, variable in breadth, obovate or broadly wedge-shaped, or sometimes round- ed at the points, the margins generally a little crenate, generally more or less imbricate, but sometimes distinct, of a bright yellow ; in some plants having a bright orange-coloured lunulate spot near the base, in others of a plain yellow. Stamens about 70 ; filaments smooth, scarcely as long as the style. Gennen downy. Style smooth, nearly straight, or a little bent towards the point. Stigma capitate, papillose. Our drawing of this species was taken from plants growing wild in Croome Hurst Wood, near Croydon, in which neighbourhood all the banks and sides of the hedges are covered with it, the soil being of a chalky nature, in which it delights ; in the same wood we, in company with Mr. Charlwood, discovered a large patch of H. surrejanum, most probably the very one from which the late Mr. Dickson originally procured his plant, which is somewhat altered by culture, as may be seen by comparison of our figure of that species, and the branch given at the bottom of this plate ; a plant of it which we planted in our garden has already much broader and flatter leaves, more like Mr. Dickson's plant ; the present is certainly the plant of Dillenius's Hortus Elthamensis, as it agrees entirely with his figure and description : both species may be grown in rock- work, and if some chalk be added to the soil, so much the better; they are readily propagated by cuttings, planted under hand-glasses in Autumn. 1. The commonest yellow variety. 2. A scarcer variety, with an orange co- loured spot at the base of each petal. 3. Helianthemum surrejanum, from a spe- cimen gathered growing wild in Croome Hurst Wood, Surry, differs from the cultivated plant already figured, in being weaker, with fewer flowered racemes, and the leaves being canescent underneath. /v \ L ^ rr>-*-, 64 vH '.'

Differs from the common single varieties at folio 34, by the flowers being double ; the largest figure in our plate, which is the old double variety, differs from the other in being more procumbent, and the flowers are fuller ; it varies in strength and in the length of its ra- cemes, also in the size of its flowers, according to the strength of the plant ; when grown in small pots it lays flat on the ground in a close tuft, its leaves are very small, having quite a different appearance from those plants that are grown out in the borders, where the leaves attain four times the size, and the racemes and flowers are much larger : the other variety, No. 2 of our plate, which is known by the name of Mr. Lee's new double yellow, is distinguished by being more erect and shrubby, and the flowers do not generally expand to the centre, but are there terminated by a greenish close tuft, not unlike a calyx, and the plant is altogether of stron- ger growth than the other ; the same difference in habit we have observed in the common single varieties, when growing together wild. Both the present varieties are very desirable for rock- work, as they are quite hardy, and need not the least protection, or they may be grown in small pots, where they make a handsome appearance when covered with flowers, and may be turned out of them, and planted into the ground at any season without injury. Cuttings of them, planted under hand-glasses, after they have done flowering, will strike root readily, and will soon become nice young plants. Our drawing was made at the Nursery of Mr. Lee, at Hammersmith, last Summer. 28 UV-J ..tj.mivi;;ir HELIANTHEMUM surrejanum. Doited-leaved Sun-Rose. Sect. IX. EUHELIANTHEMUM.

Leaves variable, lower ones nearly round or broadly ovate, others oblong, el- liptic or broadly lanceolate, obtuse or scarcely acute, green on both sides, but paler underneath, flat, or the margins very slightly re volute, dotted with numerous small dots, thinly clothed with short hairs on the upper side, and with fascicles of short stellate ones on the lower. Petioles hairy, shorter than the stipules. Sti- pules linearly-lanceolate, flat, or their margins slightly reflexed, ciliate, longer than the petioles. Racemes terminal, many-flowered, nodding before the flowers expand, the point involute, but lengthening out and becoming erect after the expansion of the flowers. Sractes short and flat, clothed with short hairs, the margins fringed. Pedicles nodding before the expan- sion of the flowers, erect when in bloom, afterwards reflexed, canescently tomentose, and also clothed with fascicles of short stellate hairs. Calyx of 5 sepals; the two outer ones very short, oblong, blunt, clothed with a mealy pubescence ; inner ones ovate, obtuse, con- cave, membranaceous, yellowish, strongly 4-nerved, slightly covered with a mealy pubescence, the nerves clothed with tufts of spreading hairs. Petals 5, very narrow, lanceolate, acute, generally toothed or lacerate, seldom entire, quite distinct and spreading, sometimes scarcely as long, at other times nearly double the length of the calyx, of a plain yellow colour. Stamens about 50, unequal in length, but very short, scarcely as long as the germen : filaments smooth, yellow. Germen downy. Style smooth, slender, and twisted at the base, and thickened upwards. Stigma capitate, papillose. Specimens of this rare plant were brought to us last Summer by Mr. David Don, from the garden of Mrs. Dickson, of Croydon, in Surrey, where the plant had been planted by the late Mr. Dickson, who discovered it growing wild near that place ; but at present, we believe, no person knows where to find it wild ; or it has perhaps been sometimes overlooked or confused with H. vulgar e : we heard of its being found last year near Dartford, in Kent ; but as we have not seen speci- mens of it, we are not certain if it really were the same species; it is certainly a very likely situation for it: we observed the flowers of it come much larger in Autumn, than they did in Summer, nearly equal in size to the Cistus sampsucifolius of the Botanical Ma- gazine, which will most probably prove to be the same species, as Dr. Sims was rather inclined to believe when he published it ; or perhaps that may be a hybrid production between the present and some other spe- cies. The present plant is quite hardy, thriving well in rock- work or by the side of a bank, where it will not be killed by too much moisture ; it may also be grown in pots, where it will flower very fine, and will not grow so luxuriant. Cuttings, planted under hand-glasses, root readily. N. 69 HELIANTHEMUM grandiflorum Large-flowered Sun- Rose. Sect. IX. EUHELIANTHEMUM. Suprafol. 7. * Petalis luteis.

Petioles short, pubes- cent. Stipules linearly lanceolate, acute, fringed, longer than the petioles. Racemes terminal, nodding before expansion, afterwards becoming erect. Bractes scarcely so long as the pedicles, resembling the stipules, but rather shorter. Pedicles downy, nodding before the expansion of the flowers, then becoming erect, after flowering reflexed. Calyx of 5 sepals, a little hairy, the hairs pressed inwards ; two outer ones very small, more hairy than the inner ones, fringed : inner ones ovate, concave, membranaceous between the nerves. Petals 5, large, broadly obovate or obcordate, very much imbricate, of a bright straw-colour. Stamens numerous, unequal in length. Style twisted, about the length of the stamens, slender at the base, and thick- ened upwards. Stigma capitate. According to M. Decandolle, the present species is a native of the Alps and Pyrenees, also of Tauria; but we believe the Taurian plant to be a distinct species, being of quite a different habit, and laying quite flat on the ground, where its branches spread to a consi- derable distance ; we saw several plants of it last year at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham, who raised it from seeds received under the name of Cistus tauricus. Our drawing of the present plant was made at the Nursery of Mr. Colvill ; we also received specimens of it from Mr. Mackay, of the Clapton Nursery. It is nearly related to H. vulgar e, but is of much stronger growth, and its flowers are of a paler colour, and con- siderably larger. It makes a pretty plant for the adorn- ing of rock-work, or it may be grown in a small pot, and will endure our Winters, except very severe ones, without protection. Cuttings of it, planted under hand- glasses, in Autumn, strike root freely. r 7^ 105 HELIANTHEMUM tauricum. Taurian Sun- Rose. Sect. IX. EUHELIANTHEMUM. Suprafol. 7. * Petalis luteis.

Stigma capitate, papillose. Our drawing of this pretty species was made from a plant at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham, who raised it from seeds several years since, that had been given them by A. P. Hove, Esq. as the H. tauricum of Dr. Fischer ; it has most probably been confused with H. grandiflorum by many authors, as that species is said to be a native of Tauria, as well as of the South of Europe ; but when the plants are seen grow- ing together, no two species had need appear more dis- tinct, the present spreading flat on the ground, and ex- tending its branches round to a great distance, and these are only slightly suffrutescent at the base, whereas H. grandiflorum grows upright, or its branches spreading and ascendent, forming a neat little bushy shrub. The present plant is well adapted for the ornamenting of rock- work, as its spreading branches will cover a good space in a short time, and it is easily kept within bounds, by cutting in the longest branches occasionally, the young branches that then shoot out will all be ter- minated by racemes of flowers, so that by that means a succession of bloom may be kept up from the latter end of May till October ; it succeeds well in a light sandy soil, or a mixture of loam and peat will suit it very well ; young cuttings, planted under hand-glasses the latter end of Summer, will strike root in a few days. 77 77 73 HELIANTHEMUM barbatum Bearded Sun- Rose.

Stem suffruticose, erect or ascending, very much branched : branches erect, thickly clothed with bunches of spreading shaggy hairs, as is every other part of the plant, except the corolla. Leaves opposite, crossing each other, rather crowded, underneath strongly nerved, bluntish : lower ones nearly round or ovate : upper ones elliptic, all hairy on both sides, the hairs in stel- late bunches ; of a pale green colour on both sides, but palest underneath. Petioles rather long, a little flat- tened on the upper side, and rounded on the lower. Stipules leaf-like, oblong, bluntish, fringed, a little longer than the petioles. Racemes terminal, many- flowered, densely hairy or bearded with long hairs, much lengthened after flowering, curved inwards be- fore the flowers expansion, afterwards erect. Bractes oblong or ovate, obtuse, fringed. Pedicles of a brown- ish purple, nodding before flowering, erect when in flower, afterwards recurved. Calyx of 5 sepals, the 2 outer ones small, ovate or oblong, obtuse, inner ones u roundly ovate, obtuse, concave, strongly 4-nerved, the nerves of a brownish purple, much warted, and thickly clothed with bunches of spreading villous white hairs. Petals 5, obovateor obcordate, with crenulate margins, more or less crumpled, of a bright yellow, rather dark- est at the base. Stamens from 60 to 70, longer than the style ; filaments smooth, slender, yellow : pollen bright yellow. Germen sericeous. Style shorter than the filaments, twisted at the base, thickening upwards. Stigma capitate, papillose. The present very distinct species, is a native of the South of Europe, but succeeds well in the open air of this country, without any protection ; it is a very de- sirable plant for the adorning of rock- work, and suc- ceeds well in any light sandy soil ; it also thrives and flowers well in small pots, in which manner a collection of the various species and varieties of this handsome genus may be grown to great advantage, and will make a fine show when in bloom ; and those sorts that are rather tender, may have a mat or two thrown over them in severe frosty weather, which is all the protec- tion they require, this will also answer the same pur- pose as rock- work, where it is inconvenient to erect it ; and the greater part of them are cheap plants, so that a collection may be obtained at a small expence ; and what sorts cannot be bought at one nursery, may be procured at some of the others. Cuttings of them all strike root freely, planted under hand-glasses, in August or September. Our drawing was made from a plant in the extensive collection at the Garden belonging to the Apothecaries' Company at Chelsea, where it was raised from seed that Mr. Anderson received from France. 80 HELIANTHEMUM nummularium.

Petioles very short and very hairy. Stipules linearly oblong, hairy and fringed, double the length of the footstalks. Racemes several-flowered, curved inward before the flowers expand, afterwards lengthening out, and remaining erect. Bractes oblongly linear, hairy and ciliate. Peduncles brown, thickly clo- thed with hispid hairs, nodding before the flowers ex- pansion, nearly erect when expanded, after flowering reflexed. Calyx of 5 sepals, which are hispidly hairy : 2 outer ones small, oblong, bluntish : inner ones con- cave, membranaceous, bluntish, 4-angled, middle an- gles of a brownish purple, outer ones green. Petals 5, slightly imbricate, obcordate, slender and distinct at the base, of a bright yellow, darkest at the bottom. Stamens about 80, about the length of the style : jfila- ments very slender, smooth, pale yellow : anthers small, attached to the filament by the back : pollen light orange-coloured. Germen clothed with close- pressed silky hairs. Style smooth, bent near the base. Stigma capitate, granular. The present plant is nearly related to H. vulgare, but is readily distinguished by its broader flat leaves, that are green on both sides ; we believe it to be the H. obscurum of most authors ; but as the present name has the right of priority, that of obscurum may now be dropt altogether, as the H. obscurum of Decandolle is without doubt the H. barbatum of Lamarck, which is the oldest name ; that is a very distinct species from the present, always growing erect, whereas the present is always procumbent, and is much less hairy. It is quite hardy, being a native of France, Switzerland, and Italy, succeeding well in the open border, or in rock- work, thriving best in a light sandy soil : young cut- tings, planted under hand-glasses, root readily. Our drawing was made from a plant at the Nursery of Mr. Colvill, who received it from Switzerland. We have this Summer flowered plants of H. tomen- tosum (Cistus tomentosus of English Botany), brought from Scotland last year by Mr. D. Don, and they prove to be nothing more than H. vulgare., as has been already stated by Dr. Hooker: plants brought by us from the neighbourhood of Croydon, flowered by the side of it in our garden, and we could not perceive the least difference in them. 109 HELIANTHEMUM hirtum.

Leaves opposite, the lower ones ovate, the others oblong, obtuse, revolute at the margins, thickly covered with spreading hairs : upper side of a pale green ; underneath clothed with a close white tomentum. Petioles short, hairy. Stipules rather small, but longer than the petioles, those at the upper leaves largest, very hairy. Racemes terminal, several-flowered, at first nodding, but becoming erect as the flowers expand. Bractes similar to the stipules, but rather larger. Pedicles slender, nodding before the flowers expansion, erect when in bloom, afterwards re- flexed, densely hairy. Calyx of 5 sepals, densely covered with spreading white hairs ; the two outer ones narrow, linear, spreading, of a brightish green : the inner ones ovate, acute, concave, strongly veined, of a pale whitish green colour. Petals 5, imbricate, obcordate, veined from the base, where they terminate in a saffron-coloured spot. Stamens numerous, of various lengths : jilaments yellow : pollen golden yellow. Germen woolly. Style a little bent at the base, about the length of the stamens. Stigma a sort of club-shaped head. The present pretty species is a native of the South of Europe, and the Levant, and therefore requires a little protection in severe frosty weather; if planted ou-t in rock-work, the covering of a mat or a little hay or straw, or any other dry covering, will be sufficient to protect it in the severe frost, giving it full admission to the air when the weather is mild ; or if the plants are not too large, a common garden pot placed close over them in frosty weather will preserve them very well. It is also a good plan to have some in small pots, to preserve in frames all the Winter ; they can then be turned out wherever they are wanted in Spring, as at that time they will grow very fast, and will soon make fine plants : a mixture of sandy loam and peat is a very proper soil for them; and young cuttings, planted under hand- glasses, in August or September, will strike root freely. Our drawing was made from a plant in the rock-work at the Botanic Garden belonging to the Apothecaries' Company, at Chelsea, in the Summer of 1828. 89 HELIANTHEMUM Anderson! Mr. Andersons Sun- Rose.

Suffruticose, procumbent, very much branched, soon forming a large spreading dense tuft : branches ascend- ing, rather slender, densely clothed with a close-pressed white tomentum, as are the petioles, peduncles, pedi- cles, and calyx. Leaves opposite, oblongly lanceolate, bluntish or scarcely acute, the margins slightly rolled back, the upper side clothed with a thinnish loose wool, and of a greyish hoary colour, underneath clo- thed with a dense white tomentum. Stipules linearly subulate, fringed and terminated with longish hairs, rather longer than the petioles. Racemes terminal, long, many-flowered, nodding before the flowers expand, afterwards becoming erect. Bractes linear, acute, flat, of a green colour, broader than the stipules, their mar- gins tomentose. Pedicles densely clothed with a close- pressed white tomentum, nodding before the flowers expansion, then becoming erect, afterwards becoming reflexed, and twisted when in fruit. Calyx persistent, clothed with a white tomentum, also with woolly spread- ing hairs ; two outer sepals very small, ovately lanceo- late, bluntish : the three inner ones broadly ovate, concave inwards, scarcely acute, strongly 3 or4-nerved, 2 A transparent between the nerves, showing the yellow petals through before they expand. Petals 5, roundly obovate, very much imbricate, varying on the same plant from a bright yellow to a pale straw-colour, generally marked with a saffron-coloured spot near the base. Stamens numerous : Jilaments yellow : pollen orange-coloured. Germen tomentose. Style smooth, very slender, and twisted near the base, thickening gra- dually upwards. Stigma capitate, papillose. Capsule tomentose, large and inflated, triangular, three-celled, 9 to 12-seeded. Seeds brown, angular, rough. This pretty and curious plant is of hybrid origin, having been produced from the seed of H. croceum, that was fertilized by the pollen of H. pulverulentum, in the rock-work, at the Apothecaries' Company's Garden at Chelsea, where it sowed itself last year, and this year produced flowering plants, that grew very fast, and were covered with flowers from May last, to the end of November ; the flowers were very variable, some being of a bright yellow, and others on the same plant, and sometimes on the same branch, of a pale straw-colour, so that they made a curious variegated appearance, the yellow flowers coming nearest to the female parent, and the straw-coloured ones approaching nearer to the male, which was a white-flowered species ; the form of the leaves and habit of the plant is also intermediate between the two. It is a very desirable plant for orna- menting rock-work, as it continues in flower for such a length of time, and is also a fast grower; it also succeeds well in small pots, planted in a light sandy soil ; and young cuttings, planted under hand-glasses in Autumn, strike root readily. We have named it in compliment to our respected friend, Mr. William Anderson, to whom we are obliged for the opportunity of making drawings of many rare species, which we have not seen in any other collection.

Stems procumbent, rough and rugged, much branch- ed : branches spreading in all directions, slightly tomen- tose, the upper part more densely so and canescent. Leaves opposite, petioled, lanceolate, acute, the margins more or less uneven, a little undulate, and slightly re- volute, green on both sides, and clothed with fascicles of longish hairs, which are stellately spreading. Pe- tioles also clothed with fascicles of hairs, channelled on the upper side and rounded underneath. Stipules linear, acute, fringed with long hairs, green on both sides, ge- nerally about double the length of the footstalks. Ra- cemes long, tomentose, many-flowered, nodding before the expansion of the flowers, afterwards becoming erect. Pedicles densely tomentose, drooping before the expan- sion of the flowers, erect when in bloom, afterwards re- flexed. Calyx of 5 sepals, densely clothed with woolly hairs, the two outer ones very small, lanceolate, blunt- ish, channelled on the upper side, three inner ones ovate, unequal on one side, membranaceous,strongly4rnerved, concave on the upper side and convex below. Petals 5, obovate, crenulate, sometimes emarginate, of a palesul- phur colour, with a yellow mark near the base. Sta- mens about 60, about the length of the style : filaments very slender, smooth, pale yellow ; pollen golden yellow. Germen downy. Style smooth and bent a little near the base, thickening upwards. Stigma capitate, slightly 3-lobed, papillose. The present plant is nearly related to H. sulphur eum, but differs sufficiently in habit, and in its woolly calyx, the calyx of H. sulphureum being glossy, and nearly smooth. The present is a very proper plant for adorn- ing rock- work, or to grow in small pots, and will stand the severity of our Winters in the open air without pro- tection, continuing in bloom the greater part of the Sum- mer ; it succeeds well in a light sandy soil, or a mix- ture of sandy loam and peat will suit it very well. Young cuttings, planted under hand-glasses, in Autumn, strike root immediately. Our drawing was made from a plant at the Nursery of Mr. Colvill, King's-road, Chelsea. 93 HELIANTHEMTJM stramineum.

Sujfrutescent, procumbent, very much branched : bran- ches elongated, and spreading round to a considerable distance, thickly clothed with short hairs when young, and the upper part with a canescent tomentum. Leaves opposite, petiolate, flat, or very slightly recurved at the margins, the upper side of a dark green and very hairy, underneath clothed with a close white tomentum : lower ones roundly oval and obtuse ; the upper ones much longer, oblongly lanceolate, and more acute. Petioles short, hairy, flat on the upper side, and rounded un- derneath. Stipules linear, acute, fringed, more than double the length of the petioles, green on both sides. Racemes terminal, many-flowered, nodding before the expansion of the flowers, afterwards becoming erect. Bractes linear, acute, fringed, and hairy, about the length of, or nearly as long as the pedicles. Pedicles to- mentose, and clothed with short hairs, drooping before the expansion of the flowers, erect when they are ex- panded, afterwards reflexed, and more or less twisted. Calyx of 5 sepals ; the two outer ones small, linear, dark -2 B green, very hairy, and generally reflexed at the points ; the three inner ones broadly ovate, bluntish, concave inwards, membranaceous, strongly 3 or 4-nerved, be- tween the nerves smooth and glossy, the nerves hairy. Petals 5, obovate, narrow at the base and rounded at the point, distinctly spreading, not at all imbricate, of a bright straw-colour. Stamens numerous, scarcely so long as the style : filaments smooth, yellow : pollen orange-coloured. Germen triangular, downy. Style smooth, twisted at the base, where it is very slender, becoming gradually thickened upwards. Stigma capi- tate, slightly 3-lobed, papillose. Our drawing of this pretty plant was made at the Nursery of Mr. Mackay, at Clapton, last Summer, where we saw several fine plants of it in full bloom ; we are not certain whether it is an original species, or a hybrid production, but most probably the latter; as from its colour, we should suspect it to be intermediate between one of the white, and one of the yellow flowered spe- cies : it is a very free grower, and an abundant bloomer, and succeeds well in rock-work, or in a dry border; or it may be grown in small pots, in a mixture of sandy loam and peat, when of course it will be more dwarf, and its flowers will not be quite so large, but still will make a handsome appearance, intermixed with other species and varieties ; in our opinion nothing can ap- pear more brilliant and interesting than a good collec- lection of the dwarf species when in bloom, if grown in pots and placed together in a group, that their diffe- rences may be more readily observed ; the present plant is readily increased by young cuttings, planted under hand-glasses, any time from the beginning of August to the end of September. 94 HELIANTHEMUM stramineum j3 multiplex Full-flowered straw-coloured Sun-Rose.

Petioles short, flattened on the upper side, and rounded below. Stipules linear, acute, fringed, green on both sides, generally more than twice the length of the peti- oles. Racemes terminal, several-flowered, nodding be- fore the flowers expansion, becoming gradually erect as they expand. Bractes linearly lanceolate, acute, hairy, about the length of the pedicles, or sometimes not quite so long. Pedicles clothed with a woolly pubescence, nodding in the bud state, and becoming erect as the 2 B 2 flowers expand. Calyx of 5 sepals : the two outer ones very small, green, and hairy : the three inner ones, ovate, blunt, concave inwards, membranaceous, strongly 3 or 4-nerved, smooth and glossy, the nerves slightly hairy. Flowers very double or full of petals, that are un- equal in size and form, of a pale straw-colour, marked with orange at the base, and more or less veined with green. Our drawing of this pretty double variety was made from a plant at the Nursery of Mr. Lee, at Hammer- smith ; it is not so strong a grower as the single variety, but makes a very pretty plant for a pot, or for the orna- menting of rock-work, thriving well in a light sandy soil, mixed with a proportion of peat ; and when covered with its pretty double flowers, it makes an elegant appear- ance, particularly when intermixed with some of the brighter flowered and more brilliant species ; it is not quite so hardy as some of the sorts, and some pots of it should be preserved in frames through the Winter ; or if planted in rock- work, should be covered in severe frost, by an empty pot being placed over each root, or a little hay or straw, or some other covering, when it will succeed very well : young cuttings, planted under hand-glasses in August or September, soon strike root. 37 HELIANTHEMUM sulphureum Sulphur-coloured Sun-Rose.

Pedicles tomentose, nodding before expansion, erect when expanded, afterwards re- flexed. Calyx of 5 sepals; the two outer ones very small, narrowly lanceolate, oblique, acute, fringed, pur- ple at the base, the upper part green: inner ones nar- rowly ovate, acute, concave, membranaceous, strongly L 4-nerved, glossy, the nerves slightly hairy. Petals 5, obovate, crenulate, generally notched at the point, widely spreading, distinct, or sometimes slightly over- lapping at the base, of a bright sulphur colour, yellower towards the base. Stamens above 50, shorter than the style. Germen globular, downy. Style smooth, bent about the middle, much thickened below the stigma, and becoming gradually slenderer downwards. Stigma capitate, slightly 3-lobed, pustulose. This pretty little plant is a native of Spain, and is well adapted for the ornamenting of rock- work, when mixed with other species ; it will stand our mildest winters well without the least covering, but in very se- vere frosts it requires a little protection, either with a mat or some straw or fern, except there be a sufficient quantity of snow to protect it ; plants of it may also be grown in pots in a light sandy soil, where they will thrive well, and produce an abundance of flowers; they can then be protected by being placed in a frame in se- vere weather; like the other species of this section, it succeeds well by cuttings, planted under hand-glasses in August or September, when they will soon strike root.

Stem suffruticose, procumbent, branching in all di- rections : branches ascending, purple, when young clo- thed with a thin tomentum, which wears off by age, they then become smooth and glossy, but are thinly warted. Leaves oblongly-lanceolate, scarcely acute, rather concave and channelled on the upper side, which is green and hairy ; underneath clothed with a close dense white tomentum, the margins slightly rolled back : upper leaves narrowest and more acute. Peti- oles short, pubescent. Stipules lanceolate, acute, about twice the length of the petioles, fringed with long hairs, the ends of which bend inwards, the points setose, or tipped with little bristle-like hairs. Racemes terminal, several-flowered, nodding before expansion, afterwards becoming erect. Bractes lanceolate, fringed, more than half the length of the pedicles, sometimes full the length. Pedicles downy, nodding before the expansion of the flowers, erect when in bloom, afterwards re- flexed. Calyx of 5 sepals, the two outer ones very small, oblong, obtuse, hairy, the three inner ones ovate, scarcely acute, concave, strongly 3 or 4-nerved, very hairy on the nerves, the hairs in bunches, which are seated on small tubercles or warts, margins and be- tween the nerves membranaceous and tomentose. Pe- tals 5, a little longer than the calyx, broader than long, rounded, very much imbricate, of a dark copper co- lour, with a darker mark at the base.

Stigma capitate, papillose. Our drawing of this plant was made at the Nursery of Mr. J. Lee, at Hammersmith, last Summer ; it is- most probably a hybrid production, as its leaves are very frequently variegated ; it makes a very pretty plant for the adorning of rock-work, where it will flower the greater part of the Summer ; or it will thrive well in small pots, in a mixture of light sandy loam and peat, when it will require a little protection in Winter, either in frames, or to be covered with a mat in frosty weather. Cuttings root freely, planted under hand-glasses, in Autumn. 101 HELIANTHEMUM Milleri. Mr. Miller V Sun- Rose. Sect. IX. EUHELIANTHEMUM.

Stigma capitate, papillose. The present plant is nearest related to H. hyssopifo- lium, from which it differs in its trailing prostrate stems, dull green and rough, not glossy smooth leaves, which are also much more hairy, and they have quite a differ- ent appearance when seen growing together ; it is also related to H. nummularium; but that is a much more branching plant, with yellow loose-petaled flowers ; it may probably be a hybrid production between the two. The plant from which our drawing was made, was sent to us by Mr. J. Miller, of the Bristol Nursery, with several other sorts that are not common in the neighbourhood of London ; it makes a very desirable plant for the ornamenting of rock-work, its flowers being so different in colour from most others, thriving well in a light sandy soil ; it also makes a handsome appearance grown in small pots, in a mixture of sandy loam and peat, and will continue to bloom in succes- sion all the Summer, and till late in Autumn, the young shoots as they are produced being generally terminated by a raceme of flowers; it is quite hardy, having stood the whole of last Winter in the open border of our gar- den without the least protection. Cuttings, taken off in the young wood, and planted under hand-glasses, in July or August, will strike root in a few days. 92. 92 HELIANTHEMUM hyssopifolium a crocatum.

Petioles short, flattened on the upper side, hairy. Stipules lanceolate, acute, hairy and fringed, bristle-pointed, about twice the length of the petioles. Racemes terminal, many- flowered, nodding before expansion, and becoming erect as the flowers expand. Bractes lanceolate, acute, hairy, and fringed, shorter than the pedicles.

Stamens numerous, unequal in length : Jilaments smooth, yellow. Germen silky. Style about the length of the stamens, nearly straight, or very little bent at the base, slender at the base, and thickening upwards. Stigma capitate, pa- pillose. Our drawing of this handsome variety was taken from a plant at the Nursery of Mr. J. Mackay, at Clapton, where it was grown with numerous other species and varieties, in a border at the front of his Greenhouses ; in our opinion, it is a more beautiful variety than the copper-coloured one, and is a delight- ful plant for ornamenting rock- work, or to be grown in a dry border, thriving well in a light sandy soil, or if grown in pots, an equal portion of sandy loam and peat will suit it well ; it is pretty hardy, but it will be best to give it a slight covering in severe frost. Young cuttings, planted under hand-glasses in Autumn, strike root readily. We have this Winter tried a great many species of Cistus in various situations in the open ground, and have found them succeed best, and suffer the least from frost, in a border with a north-west aspect ; scarcely any of them were injured in the least, though several were of the tenderer sorts, and they had not the least covering or protection ; we attribute this to their being in a more dormant state, and their wood there- fore more hardened to withstand the frost ; as those in a southern aspect, though partially covered, were hurt much worse, which we account for by their being more in a growing state. 58 HELIANTHEMUM hyssopifolium p cupreum.

We believe the present very distinct plant belongs to H. hyssopifolimn of Tenore, as it agrees precisely with his description ; we are acquainted with two other very distinct varieties of it, one with flowers of a lighter colour, the other with double flowers ; it is one of the strongest growing species of this section, and is a very desirable plant for adorning rock- work, where it makes a grand appearance when covered with its large bright flowers, succeeding well in a light sandy soil ; and young cuttings, planted under hand-glasses, in August or September, will strike root readily. Our drawing was made from a plant at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham. 72 HELIANTHEMUM hyssopifolium ^ multiplex. Double-flowered Hyssop-leaved Sun-Rose. Sect. IX.

Leaves flat, very hairy, shorter and smaller than in the single varieties : lower ones ovate, bluntish ; upper ones nar- rower, oblongly lanceolate, acute, dark green on the upper side and paler underneath. Petioles short, pu- bescent. Stipules about half the length of the leaves, lanceolate, acute, very hairy, fringed and bristle- pointed . Racemes terminal, many-flowered, nodding before ex- pansion, afterwards becoming erect. Uractes lanceo- late, acute, very hairy, shorter than the stipules. Pe- dicles downy, nodding before the flowers expansion, erect or spreading when in bloom, afterwards reflexed. Calyx of 5 sepals, very hairy, the two outer ones very small, lanceolate, acute ; inner ones ovate, acute, con- cave, strongly nerved. Flowers more or less double or full of petals, copper-coloured, darkest at the base, some- times making an attempt at another flower in its centre. Stamens, many perfect, others are changed into petals. Germen and Style generally monstrous. Our drawing* of this plant was made at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham. It makes a pretty plant for the adorning of rock- work, producing its fine double flowers, the greater part of the Summer. It may also be grown in small pots, in a mixture of sandy loam and peat ; the plants can then be protected by mats, or placed in frames in severe frost. A collection of the different species and varieties of this handsome genus, grown in pots, and placed to- gether, in a clump, make a splendid appearance, when in flower, in the Slimmer ; we scarcely know any tribe of plants that make so gay a show when in bloom ; and though the flowers continue but a short time, still the succession that follows, makes that of little or no con- sequence. The present plant is readily increased, by planting young cuttings under hand-glasses, in August, but the glasses must be removed from them as soon as rooted, or they will be liable to damp. 106 HELIANTHEMUM mutabile /3 roseum.

Style smooth, about the length of the Stamens, nearly straight or slightly bent at the base, thickening upwards. Stigma capitate, pa- pillose. Our drawing of the present pretty plant was taken at the Nursery of Mr. J. Mackay, at Clapton, where it was grown with a fine collection of other species, in a border at the front of the Greenhouses, and made a splendid appearance, when all were covered with bloom. The present species is a native of Spain, and endures our Winters well in the open ground, except when they are very severe, thriving well in rock- work, or on a dry bank, and producing its flowers all the Summer and till late in Autumn ; the flowers are very variable in colour, at first bright rose, then changing to a dull lilac or flesh colour, and at length becoming pale blush, which gives the plant a singular appearance : if the Winters are at any time unusually severe, it will be best to protect it a little with some slight covering, or if some plants are kept in small pots in frames through the Winter, they will be ready to turn out where they may be wanted in Spring ; a light sandy soil suits it best ; and young cuttings, planted under hand-glasses the latter end of Summer or Autumn, will root readily. 55 HELIANTHEMUM roseum, Rose-coloured Sun-Rose.

It is a native of the South of Europe, and requires a slight covering in severe frosty weather, but will endure our mildest Winters in the open air without the least pro- tection. It thrives well in a light sandy soil, or an equal mixture of light sandy loam and peat will suit it very well. It makes a very pretty plant amongst others for the adorning of rock- work, where it will produce an abundance of flowers nearly all the Summer; it may also be grown in small pots, which can be protected from the severe frost. Young cuttings, planted under hand- glasses, from July to September, will strike root readily. 86 86 HELIANTHEMUM roseum 0. multiplex. Double-flowered Rose-coloured Sun- Rose. Sect. IX.

Stigma capitate, papillose. The present is a very handsome and showy plant when covered with its brilliant flowers ; it belongs to the same tribe as H.polifolium, to which it is nearly re- lated, but is readily known at all times by the green upper side of the leaves ; those are very variable in form and size, some being nearly round or oval, and obtuse, varying to lanceolate or linear, and more or less acute ; the petals are nearly of the same form as H. polifotium, and are also notched at the points, but they are of a very different colour : it makes a desirable plant for the ornamenting of rock-work, or to be grown in small pots, succeeding best in a light sandy soil, and is co- vered with bloom the greater part of the Summer and till late in Autumn; young cuttings, planted under hand-glasses, the latter end of Summer or Autumn, strike root freely.

Stigma capitate, papillose. This very pretty plant is now very common in the collections about London, but we cannot find any de- scription agree with it in any of the works that we have examined ; it is readily distinguished from H. rhodan- thum by its warted stalks and calyces, and by its smooth and shining stems ; its habit is also very differ- ent ; it is one of the most ornamental plants of the genus for adorning rock- work, as it is quite hardy, and continues to flower all the summer, and till late in autumn ; it will also succeed well on a dry bank, or in any common border of the flower garden where it does not get too much moisture ; in some of our collections it is considered as a variety of H. vulgar e, but it has certainly nothing to do with that species, from which it differs more than from any other species in the sec- tion ; we believe many species have been confused together by the short descriptions that have been given of them, and those chiefly from dry specimens that have dropt their petals. Specimens of this natural order of plants should always be gathered in the morn- ing, as soon as the flowers expand, and before their anthers are burst, for as soon as that takes place, the stigma becomes fertilized by the pollen, and the petals will not remain long after. Our drawing was taken from a plant, at the Nursery of Mr. Colvill, where it is cultivated in pots of light sandy soil, and makes a splendid appearance all the summer; young cuttings root freely under hand- glasses in the open ground, if planted in autumn.

Stamens numerous, scarcely as long as the style, from 70 to 80 : filaments slender, smooth, bright yel- low ; pollen yellow. Germen clothed with dense wool. Style smooth, bent like a bow near the base, the upper part thicker and erect. Stigma capitate. This very handsome flowering plant is a native of Spain, and is one of the most ornamental species for the adorning of rock- work : it is also quite hardy, our drawing being taken from a fine plant, growing lux- uriantly with many other handsome species, in the rock- work of the garden belonging to the Apotheca- ries' Company, at Chelsea, in June last; nothing could make a more brilliant appearance, than the va- rious species of different habits, with flowers of various colours with which the plants were decked every day for about two months ; it also makes a handsome ap- pearance when grown in pots, in which it will thrive very well, or on a dry bank in the garden ; nothing is more injurious to this family of plants, than too moist a situation in Winter ; like most of the species of this genus, the present plant grows freely in a mixture of sandy loam and peat, or any light sandy soil ; and young cuttings root readily, if planted under hand- glasses, in a shady situation. 51 HELIANTHEMUM canescens, Canescent Sun- Rose.

Helianthemum canescens. Swt. hort. brit. p. 36. n. 75. Stem suffruticose, branching in all directions : bran- ches procumbent, their points ascending, thickly clothed with a close pressed canescent tomentum. Leaves op- posite, variable, flat or sometimes very slightly revolute at the margins, underneath clothed with a dense white tomentum, the upper side of a dull glaucous green, oc- casioned by a short close pressed pubescence, scarcely perceptible to the naked eye : lower ones ovately oblong^ flat, obtuse or rounded at the points : upper ones lan- ceolate, acute, when young the margins slightly revo- lute, channelled on the upper side. Petioles pubescent, on the lower leaves about the length of the stipules, on the upper ones shorter. Stipules linear, acute, pubes- cent and ciliate, greener than the leaves. Racemes ter- minal, many-flowered. Bractes linear, fringed, about half the length of the pedicles. Pedicles densely clothed with a close white tomentum, nodding before the flowers expand, scarcely erect when expanded, afterwards re- flexed. Calyx of 5 sepals, smooth, or scarcely pubes- cent, 2 outer ones very small, oblongly lanceolate, blunt- ish, of a brownish purple, inner ones ovate, concave, scarcely acute, membranaceous, strongly four-nerved, the nerves more or less tinged with purple, and slightly pubescent. Petals 5, broader than long, rounded, more or less crumpled, very much imbricate, of a reddish crimson with a small orange-coloured spot at the base. Stamens from 60 to 70, about the length of the style : filaments smooth, very slender, pale yellow : pollen yel- low. Germen densely tomentose. Style much twisted, and very slender at the base, thickening upwards. Stigma capitate, granular. Our drawing of this handsome plant was made at the Nursery of Messrs. Whitley, Brames, and Milne, at Fulham ; it is nearly related to H. rhodanthum, but is readily distinguished by its canescent leaves and stronger growth : it is also related to H. roseum of Jacquin, but we think it can scarcely be the same spe- cies, and we have not yet had the opportunity of com- paring them. H. roseum of Allioni and Decandolle is a very different plant, of which we intend giving a figure in our next Number ; the present, we believe, bears the darkest coloured flower, if not the handsomest of the genus ; it is also very large for the size of the plant, which is well suited for the ornamenting of rock- work, but will require a little covering in severe frosty weather ; it succeeds well in a light sandy soil ; and young cuttings, planted under hand-glasses in Autumn,, soon strike root. 79 HELIANTHEMUM virgatum.

Stem suffruticose, producing numerous branches, which are at first erect, but as they lengthen out, they become more or less decumbent, not being strong enough to support their weight, their points ascending or becoming again erect, tinged with purple, and clo- thed with a short white close tomentum, quite white and thick on the young branches, but as they become older it gradually wears off. Leaves opposite, linear, acute, canescent on both sides, but most so under- neath, channelled on the upper side and strongly one- nerved on the lower, the margins slightly revolute, clothed on both sides with a close-pressed pubescence. Petioles clothed with a close-pressed canescent pubes- cence, flattened a little, and furrowed on the upper side and rounded at the back. Stipules linearly subulate, sharp-pointed, keeled at the back, longer than the pe- tioles, thickly clothed with close-pressed white woolly hairs. Racemes terminal, several-flowered, nodding before expansion, afterwards ascending, or becoming erect. Flowers pale rose-colour, leaning forward, or slightly nodding. Pedicles clothed with a hoary pu- bescence, nodding before the expansion of the flowers, becoming more erect as they expand, afterwards re- flexed. Bractes linear, acute, broader than the sti- pules, about the length of the pedicles. Calyx of 5 sepals, hoary and pubescent; two outer ones small, oblong, obtuse, green, with a canescent margin : three inner ones ovate, obtuse, concave inwards, of a thin membranaceous texture, transparent, strongly 3-nerved, the nerves clothed with stiffish hairs. Petals 5, broad and rounded, imbricate, the points a little uneven, but scarcely crenulate, pale pink, rather darker at the sides. Stamens from 50 to 60 : filaments slender, smooth, bright yellow, scarcely so long as the style : pollen golden yellow. Capsule densely tomentose, about the length of the calyx. Style very slender at the base, where it is more or less bent, thickening a little up- wards. Stigma capitate, papillose. Our drawing of this beautiful species was taken from a fine plant, kindly sent to us from the Nursery of Messrs. Young, at Epsom, the only collection in which we have seen it ; it is a native of Barbary, and there- fore requires a little protection in Winter, either to be placed in a Frame, or to be covered with mats or straw in severe frost ; if plan ted in rock- work, a covering of straw, or a thick mat will be requisite ; but if grown in pots, they can be protected under a common garden frame ; a mixture of sandy loam and peat is a proper soil for it ; and young cuttings, planted under hand- glasses in August, will strike root readily. 38 IIELIANTHEMUM variegatum Variegated-flowered Sun-Rose.

Helianthemum variegatum. Swt. hort. brit. add. p. 469. n. 95. Stem suffruticose, much branched : branches procum- bent, spreading in all directions, their points ascend- ing, densely clothed with short white wool. Leaves opposite, lanceolate, acute, flat, or the margins some- times very slightly revolute ; underneath clothed with a dense white tomentum, the upper side channelled, of a glossy green, but clothed with a few close pressed procumbent hairs, which gives them a slightly fringed appearance, a little roughened, occasioned by the innu- merable small punctures with which the leaf is covered. Stipules linear, bluntish, or sometimes acute, fringed with small hairs, a little longer than the petiole. Ra- cemes terminal, many-flowered. Bractes linear, acute, fringed. Pedicles densely tomentose, nodding before the flowers expand, erect or a little declining when in flower, after flowering reflexed. Calyx of 5 sepals, clothed with a short thin tomentum: 2 outer sepals small, oblong, bluntish, hairy : inner ones ovate, ob- tuse, concave, membranaceous, of a violet colour, strongly 4-nervt,d, the nerves slightly hairy. Petals 5, rounded, imbricate, more or less crumpled and undu- late, the sides more or less bent inwards, beautifully variegated with white and rose-colour. Stamens about L 2 the length of the style, the stigma overtopping them, from 60 to 80 in number : filaments smooth, of a bright yellow. Pollen yellow. Germen densely tomentose. Style smooth, a little bent at the base, thickened up- wards. Stigma capitate, papillose. Our drawing of this plant was taken at the Apothe- caries' Company's Garden at Chelsea, where it is grow- ing in the rock-work in company with many other spe- cies; we believe it to be of hybrid origin, and most pro- bably between H. rhodanthum and H. lineare, which grow in company with it : when in full bloom it makes a very pleasing appearance, from the diversity of colours in its flowers, some being nearly all red, others varie- gated with dark and light red and white, and some alto- gether white; it also continues to bloom, if the weather prove favourable, from May till October ; this year we observed several flowers on it, the beginning of No- vember. It is quite hardy, having survived several Win- ters in the rock- work at Chelsea garden, without the least protection. Cuttings of it root freely, planted un- der hand-glasses in September, the glasses to have a little air at times, to keep them from damping, and the sooner they are potted off after being rooted the better, as they then establish themselves before Winter. 26 HELIANTHEMUM versicolor.

Stems shrubby, erect, from a foot to 18 inches high, much branched : branches spreading, ascendant, clothed with a canescent starry pubescence. Leaves oblong, or oblongly lanceolate, flat, or the upper side concave, upper side roughish, of a glossy green, underneath clothed with a close white tomentum : lower ones oval or rounded, upper ones narrower and more acute, margins in some of the young leaves a little revolute. Petioles short, pubescent. Stipules small, oblongly linear, a little longer than the petioles, hairy, ciliate, and terminated with short bristles. Racemes terminal, several-flowered, curved inwards before flowering, after- wards becoming erect. Bractes oblong, bluntish, hairy and ciliate. Pedicles clothed with a loose white pubes- cence, nodding before the expansion of the flowers, generally erect when in bloom, afterwards reflexed. Calyx of 5 sepals, clothed with a short canescent pu- bescence, 2 outer ones very small, spatulate, obtuse ; inner ones ovate, concave, membranaceous, strongly 4-nerved, the nerves more or less hairy. Petals 4, rounded, much imbricate, more or less crumpled, va- riable in colour, red, copper-coloured or light flesh- H2 coloured, with a dark orange-coloured spot at the base. Stamens 50 to 60 : filaments slender, smooth, bright yellow: pollen yellow. Germen densely woolly. Style smooth, curved round at the base, thickening upwards. Stigma capitate, papillose. A very fine specimen of this handsome plant was growing last Summer in the rock-work of the Garden belonging to the Apothecaries' Company, at Chelsea, where our drawing was made; it is readily distin- guished from all others to which it is related, by its stiff upright growth ; a good representation of it is given in Barretter's I cones, 440 ; but we cannot find it noticed by any modern author, nor do we see any re- ference to the figure in any work that we have exa- mined ; the flowers in our plant were very variable in colour, scarcely ever two on the plant were alike, some being of a bright red, others nearly yellow, some cop- per-coloured, others with a mixture of all those co- lours, and different shades between them, so that the plant when in flower had a curious variegated appear- ance. As the present subject is a native of the South of Europe, it cannot bear the severity of our sharpest Winters without protection: if grown in rock-work, it will require to be covered with mats or dry litter in severe weather, but in mild weather will be best un- covered ; it may also be grown in pots, where the plants will bloom well, and can be placed with the other species in frames or pits in severe frosty weather ; like the rest of the tribe, the present plant will succeed well in a light sandy soil, or a mixture of turfy loam, peat, and sand, will suit it very well. Cuttings strike root freely, if planted under hand-glasses, the latter end of Summer, or Autumn. 62- 82 HELIANTHEMUM racemosum. Long racemed Sun-Rose. Sect. IX. EUHELIANTHEMUM.

Stem frutescent, much branched, clothed with a brown roughish bark, and marked with rings, where the leaves have fallen : branches erect, cylindrical, clothed with a close-pressed hoary woolliness. Leaves opposite, petiolate, linear, oblongly or lanceolately linear, acute, channelled on the upper side, the margins revolute: upper side of a bright shining green, quite smooth on the old leaves, but slightly pubescent when young; underneath pennately veined, and clothed with a short thinnish grey woolliness. Petioles clothed with a short dense tomentum, flattened a little on the upper side and rounded below, longest on the young Autumn shoots. Stipules attached to the base of the petioles, subulate, ciliate, the hairs pointing upwards : those on the flowering shoots longer than the petioles ; but on the young Autumn shoots considerably shorter than the petioles. Racemes terminal, very long, clothed with a short dense woolliness, drooping or involute before the expansion of the flowers, afterwards lengthening out Y2 and becoming erect. Bractes fringed, similar to the up- per stipules. Pedicles longer than the bractes, densely clothed with a short grey tomentum. Calyx of 5 sepals ; the two outer ones small, bluntish, hairy, dark green ; the three inner ones ovate, acute, concave, membranace- ous between the angles, the angles marked with red or violet colour, smooth and glossy, slightly hairy. Pe- tals 5, imbricate, white, more or less uneven or crenulate at the edges, roundly obovate. Stamens numerous : fila- ments smooth, yellow: pollen orange-coloured. Style twisted at the base. Stigma large, capitate, papillose. We also received the present handsome species from Mr. Miller, of the Bristol Nursery, at the same time as the subject of the last plate ; it is a scarce plant in our collections, we having never seen it in any of the Nur- series about London ; it is readily distinguished from all others to which it is related, by its upright growth and glossy leaves, and the red veins of the calyx ; it must not be confounded with Cistus racemosus of Cavanilles, which is a variety of H. lavandul&folium, ac- cording to Dunal in Decandolle's Prodromus, and is a yellow-flowered species. The present species is a native of Spain, JBarbary, and the Canary Islands, and will stand our Winters, if not very severe, in the open ground; it is well adapted for ornamenting rock- work, from its handsome glossy foliage ; its flowers are also produced in succession near- ly all the Summer and till late in Autumn, thriving best in a light sandy soil ; it is also best to have some plants of it in pots, as those can be preserved in frames through the Winter, and can be planted out in Spring, to supply the places of any that may have been killed by frost : young cuttings, planted under hand-glasses, any time from July to September, will strike root readily. 49 HELIANTJHEMUM pilosum.

Stem shrubby, nearly erect, or ascending, branched : branches long* and slender, erect or ascending, smooth and glossy, or slightly hairy, of a purple colour, more or less warted. Leaves petiolate, linear, bluntish, bris- tle-pointed, more or less hairy, margins much revolute, deeply channelled on the upper side, of a whitish green, occasioned by a dense minute pubescence, underneath clothed with a dense white tomentum. Petioles short, pubescent. Stipules linear, bluntish, fringed with short hairs, longer than the petioles. Racemes lax, 3 to 8- flowered, clothed with a short white tomentum. Bractes linear, fringed, similar to the stipules. Peduncles slen- der, tomentose, nodding before the flowers expand, scarcely erect when in bloom, afterwards reflexed. Ca- lyx of 5 sepals, more or less hairy, thinly clothed with a white tomentum : 2 outer sepals very small and nar- row, concave, bluntish ; inner ones membranaceous, ovate, concave, bluntish, 3-nerved, nerves prominent, violet coloured. Petals 5, much imbricate, nearly or- bicular, more or less crumpled, of a paper white, stained with yellow at the base. Stamens from 60 to 70, scarcely as long as the style : filaments slender, smooth, pale o yellow: anthers attached by their back to the fila- ments: pollen bright yellow. Germen densely tomen- tose. Style smooth, twisted at the base, a little longer than the stamens. Stigma capitate, granularly fim- briate. The present plant is nearly related to H. lineare, and also to H. apenninum ; from the former it differs in its much whiter leaves, and in being more hairy ; and from both by its imbricate paper-white petals ; it is a very pretty plant for the adorning of rock- work, and continues in flower a great part of the Summer ; it is also pretty hardy, standing our milder Winters in the open air without protection ; but it is sometimes in- jured in the more severe ones ; so that it is the safest way to have a few plants in pots, to be protected in frames, or to be covered with mats in sharp frosty weather. It succeeds well in any light sandy soil, or a mixture of sandy loam and peat will suit it very well ; and young cuttings, planted under hand-glasses in Autumn, strike root readily. Our drawing was made from a plant at the Nursery of Messrs. Whitley , Brames, and Milne, last Summer. 48 HELIANTHEMUM lineare. Linear-leaved Sun- Rose. Sect. IX. EUHELIANTHEMUM.

Leaves linear, blunt- ish, opposite, with a longish slender petiole, the mar- gins more or less revolute, underneath clothed with a hoary tomentum, and having a strong prominent mid- rib, the upper side when young clothed with short close-pressed hairs, which gives them at that time a hoary appearance ; this wears off when older, and they are then green and a little glossy. Petioles pubescent. Stipules small, linearly subulate, more or less hairy, shorter than the petioles. Racemes terminal, loose, few-flowered, clothed with a hoary tomentum, before flowering curved inward, but as the flowers expand becoming erect. Bractes short, lanceolate or linear, clothed with short hairs. Pedicles clothed with a short hoary tomentum, nodding before flowering, erect when in bloom, afterwards reflexed. Calyx of 5 sepals, smoothish or slightly hairy, the two outer ones very small; inner ones ovate, acute, concave, striate, the nerves prominent, more or less tinged with red. Pe- tals 5, white, obovate or obcordate, slightly imbricate at the base, but distinct upwards. Stamens from 30 to 40. Style curved. Stigma capitate. Capsule rough- ish. Seed brown, margined with a white membrana- ceous wing. This pretty little shrub is a native of the South of Europe, and is well adapted for rock- work, but it requires a little covering in Winter, and it is best to have some plants of it in pots, and those preserved in frames in severe weather, to supply the places of any that may be killed by the severity of the weather ; they succeed well in a light sandy soil, or a mixture of sandy loam and peat will suit them very well. Cuttings, planted under hand-glasses in Autumn, will soon strike root ; they may also be raised from seeds, which ripen occasionally. 62- HELIANTHEMUM apenninum Apennine Sun-Rose. Sect. IX.

R2 Our drawing of this plant was made last Summer at the Nursery of Mr. Colvill, where it was raised from seed received from the late Mr. Schleicher, of Bex, in Switzerland ; we also received plants of it from Mr. W. Anderson, at the Apothecaries' Company's Garden, at Chelsea; it makes a pretty plant for the adorning of rock-work, where it will succeed well without the least protection ; young cuttings, planted under hand-glasses in Autumn, will strike root readily, or it may be in- creased by seeds. 88 HELIANTHEMUM polifolium.

Corolla of 5 petals, distinctly spreading, obovate, generally crenu- late at the margins. Stamens numerous, unequal in length : filaments smooth, yellow : pollen orange-co- loured. Germen clothed with a dense tomentum. Style smooth, slender, and bent near the bottom, thickening upwards. Stigma capitate, papillose. The present pretty species is a native of various parts of Devonshire and Somersetshire, but it is certainly not the H. polifolium of the continental Botanists, as they describe its leaves with a green and glossy upper side, and the calyx as smooth and glossy ; our plant is altogether hoary all over, and the calyx densely clo- thed with a short, close, white tomentum ; that it is the original plant of Dillenius, there can be no doubt, as we have specimens from the same place as he obtained those from which his figure was made ; we received our's from Mr. W. Christy, Junior, of Clapham-road, who gathered them himself on Brent-down, in Somer- setshire, and kindly sent them to us ; we are also much obliged to Mr. Thomas Clark, Junior, of Bridgewater, who was so kind as to send us seeds from the same place, which were raised at Mr. Colvill's Nursery, but by some means got lost, before they flowered. Our drawing was made from a plant in the garden of Mr. Capper, at Clapton, that had been received from Babbicombe, near Newton Abbott; we have compared the specimens with the Brent-down ones, and there is not the slightest difference in them. It is also abundant on Tor Hill, near Torquay, as we have been informed by Miss Southcote, an intelligent bo- tanical lady of that place. The plant that we believe to be H. polifolium of the continental Botanists, we possess a drawing of; it agrees precisely with their descriptions, and we intend to publish it in our next Number. The present species is quite hardy, and well adapted for rock- work ; it thrives well in a light sandy soil; and cuttings, planted under hand-glasses, root readily. The figure in English Botany is not good, nor well coloured ; the leaves are much too green. 29 HELIANTHEMUM pulvcrulentum Powdered Sun-Rose. Sect. IX. EUHELIANTHEMUM.

Leaves opposite, oblongly linear, obtuse, margins revo- lute, underneath clothed with a close white tomentum, the upper side of a glaucous powdery appearance, ori- ginating from small close-pressed white hairs, with which the upper surface is covered, and is more con- spicuous on the young leaves. Petioles short, tomen- tose and hairy. Stipules subulately linear, longer than the petioles, hairy and ciliate, bristly at the point. Ra- cemes terminal, several flowered. Bractes linear, blunt- ish, hairy and ciliate, more than half the length of the peduncles. Peduncles clothed with a dense white pu- bescence and hairs intermixed, nodding before the flowers expand, and often when in flower, afterwards reflexed. Calyx of 5 sepals, the 2 outer ones small, oblong, bluntish, very hairy : inner ones ovate, con- cave, bluntish, strongly 4-nerved, the nerves clothed with short rigid hairs, and between them with a short white close pubescence. Petals 5, much imbricate and crumpled, roundly obcordate, white with a small yel- low spot at the base, and tinged round with a sulphur colour. Stamens from 60 to 70, about the length of the style ; filaments slender, yellow : pollen yellow. Ger- men clothed with a close-pressed pubescence. Style curved, smooth, thickening upwards. Stigma capi- tate, tuberculate. Our drawing of this species was taken from a fine strong plant growing in the rock- work of the Garden belonging to the Apothecaries' Company at Chelsea, in June last : it is very hardy, as it stood the last Winter quite well, without the least protection ; it is readily distinguished from all those to which it is nearest re- lated, by its white blunt leaves, and its very much im- bricated thin flaccid petals; we do not know any one with which it can be confounded, but is nearer related to H. apenninum than any other. Its flowers are not so showy as some of the other species ; but they never- theless make a pleasing variety ; and in a large piece of rock- work, where a great many species are planted, we think the beauty depends very much on the different sorts of colours being properly mixed ; and we often see too many plants of a fine thing grown together, which very much diminishes both its beauty and rarity, particularly when there are not some less beautiful to compare with it. The present plant will grow freely in any common garden soil, and will thrive in any situation that is not too moist ; it may also be grown in a pot, in a light sandy soil, and will need no protection in Winter. Cuttings planted underhand-glasses in Autumn, strike root readily. 91 .-.- 91 HELIANTHEMUM confusum, Confused Sun- Rose. Sect. IX. EUHELIANTHEMUM.

DC. prodr. 1. p. 283. sub H. polifolio. Stem suffrutescent, procumbent, extending to a con- siderable distance, branched : branches procumbent, the points ascending, smooth when old, but clothed with a white tomentum while young, so that the lower part is smooth, and the upper part tomentose. Leaves ovate or oblong, bluntish, the lower ones shorter and rounder, flat or nearly so, underneath clothed with a short white tomentum, the upper side green, and somewhat glossy, but more or less clothed with shortish hairs ; these are most conspicuous on the young leaves, as they wear off as the leaves become older. Petioles short, flattened a little on the upper side, pubescent on the young leaves. Stipules linear, acute, longer than the petioles, somewhat hairy and fringed, of a bright green colour. Racemes terminal, elongated, several-flowered, nodding before expansion, but becoming erect as the flowers expand. Bractes green, fringed, similar to the stipules, shorter than the pedicles. Pedicles tomentose, drooping before expansion, erect when in bloom, after- wards reflexed. Flowers white and delicate. Calyx of 5 sepals ; the two outer ones small, bluntish, dark green, hairy and fringed ; the three inner ones ovate, concave inwards, bluntish, with membranaceous inner margins, striated with dark green veins, somewhat hairy but glossy. Petals 5, more or less imbricate, or somewhat distinct, rounded but uneven at the margins. Stamens numerous, spreading, unequal in length : jila- ments pale yellow : pollen golden yellow. Style about the length of the stamens, curled round at the base, slender below and thickening upwards. Stigma capi- tate, papillose. The present plant is the one generally cultivated in the Nurseries as H. polifolium, and we believe the plant intended by most of the continental botanists, judging from their descriptions ; but it has certainly nothing to do with the the English plant, though it is not very unlike the figure in English Botany, the leaves of which are coloured much too green, if it really was taken from a native specimen, as there asserted ; the present is a common plant in the Nurseries about Lon- don, and is well suited for the ornamenting of rock- work, as it is quite hardy, thriving well in a light sandy soil ; and young cuttings, planted under hand- glasses in Spring and Autumn, strike root readily. Our drawing was made, several years ago, at the Nursery of Mr. Colvill ; but we deferred publishing it, till we should have an opportunity of comparing it with the wild English species. We showed our drawing to Mr. Lagasca some time since, who immediately pro- nounced it to be the Spanish H. polifolium. 100 HELIANTHEMUM lanceolatum. Spear-leaved Sun-Rose. Sect. IX. EUHELIANTHEMUM. SuprafoLl. ** Petalis albis, roseis, rubris vel dilute sulphureis. H. lanceolatum, caule suffruticoso ramosissimo procumbente; ramis adscendentibus glabriusculis apice tomentoso-incanis, foliis lanceo- latis acutis margine subrevolutis supra viridis glabriusculis subtus tomentoso-incanis, stipulis subulato-linearibus petiolo longioribus, sepalis glabriusculis subpilosis, petalis imbricatis. Stem suffrutescent, procumbent, very much branch- ing : branches ascending or erect, clothed when young with a close white down, this wears off by age, and they then become smooth. Leaves opposite, petiolate, lanceolate, acute, slightly revolute at the margins, green and rather glossy on the upper side, but clothed with short hairs, most abundant on the young leaves, under- neath clothed with a short white tomentum. Petioles short, flattened a little on the upper side, hairy. Stipules about twice the length of the petioles, linearly subulate, hairy and fringed. Racemes terminal, many-flowered, nodding and involute before the flowers expand, but becoming erect as they come into bloom ; the flower- stem thickly clothed with white down. Brae tes linearly lanceolate, acute, hairy and fringed, nearly as long as the pedicles, and sometimes exceeding some of them in length. Pedicles densely tomentose, drooping before the flow r ers expand, erect when in bloom, afterwards reflex- ed. Calyx inflated, of 5 sepals, the two outer ones very small, bluntish, of a dark green : inner ones short, ovate, concave, blunt, 3 to 5-veined or striate, somewhat glossy but clothed with shortish hairs. Petals 5, white, imbri- cate at the margins, broadly rounded, somewhat crum- pled, narrowing to the base, a little uneven at the mar- gins, marked with yellow at the base. Stamens nume- rous: filaments smooth, slender, pale yellow: pollen orange-coloured. Style very slender, and curled round at the base, thickening upwards, where it becomes club- shaped. Stigma capitate, papillose. We believe the present plant to be one of those that has been confused with tl.polifolium by some Botanists, as we have seen it by that name in several collections ; but it is a very different plant, readily distinguished by its sharp pointed leaves, which are of a glossy green on the upper side, and by its broad imbricated petals. Our drawing was made from a plant growing in the rock- work, in the garden belonging to the Apothecaries' Company, at Chelsea, where it was raised by Mr. W. Anderson, from seeds that he received from the Conti- nent, under the name of H. polifolmm; it is quite hardy, remaining all the Winter uninjured without any pro- tection, succeeding well in a light sandy soil ; and young cuttings, planted under hand-glasses, the latter end of Summer or Autumn, strike root freely. 203. 103 HELIANTHEMUM macranthori. Great-lowered Sun-Rose. Sect. IX. EUHELIANTHEMUM. Suprafol.l. ** Petalis albis, roseis s rubris vel dilute sulphureis. H. macranthan, caule suffruticoso, ramis procumbentibus tomentosi- usculis, foliis planis ovato-oblongis acutiusculis supr& glabris sub- tils levissime tomentosis pallide cinereis, stipulis pilosiusculis pe- tiolo subaequalibus vel longioribus, calycibus striatis pilosis, petalis distinctis. Stem suffruticose, much branched : branches procum- bent, clothed with a thin tomentum, the upper part tinged with purple. Leaves large and flat, ovately ob- long, obtuse, or scarcely acute, the upper side green, smooth, and glossy, or very thinly clothed with hairs, which are mostly in pairs, underneath clothed with a short thin tomentum, besides numerous little bunches of hairs which give a greyish appearance, the hairs are fixed on minute tubercles which occasions a roughness. Petioles hairy, furrowed on the upper side and rounded on the lower. Stipules narrowly lanceolate, acute, frin- ged with long hairs : lower ones about the length of the petioles : upper ones double the length. Racemes ter- minal, nodding before expansion, afterwards becoming- erect and lengthening out. Bractes lanceolate, slightly falcate, fringed with long hairs. Pedicles clothed with a thin tomentum and some longer hairs intermixed, tinged with purple, nodding before the flowers expand, erect when in bloom, afterwards reflexed. Calyx of 5 sepals; the two outer ones small, oblongly lanceolate, spreading, and fringed with long hairs ; the three inner ones ovate, membranaceous, concave, acute, strongly 3-nerved, the nerves very prominent, and clothed with bunches of long hairs which are seated on little tuber- cles ; between the nerves smooth and glossy. Petals 5, distinctly spreading, of a cream-coloured white, pale yellow near the base, obovately wedge-shaped, .very slender at the base, slightly crenulate at the ends. Sta- mens about 80 : filaments long, smooth, bright yellow : pollen yellow. Germen densely tomentose. Style smooth, a little bent and slender at the base, thickening up- wards, about the length of the stamens. Stigma large, capitate, papillose. Our drawing of the present strong growing and large flowered species, was taken from a plant at the Nursery of Mr. J. Lee, at Hammersmith, where it was culti- vated in pots, and also in the open ground ; it is of rather a loose straggling growth, producing long shoots that spread out on the ground, but its flowers are very large and showy ; it is also quite hardy ; and the best situation for it is rock- work, where it will grow more compact, by being in a dry exposed situation, than it will if planted in rich soil in the flower-borders : young cuttings of it strike root readily if planted under hand- glasses, anytime from July to the end of September; it is nearer related to H. mutabile than to any other species. 104 u 104 HELIANTHEMUM macranthon multiplex Double great-flowered Sun- Rose.

Petioles short, hairy, furrowed on the upper side and rounded on the lower. Stipules linearly lanceolate, acute, fringed with long hairs, lower ones about the length of the pe- tioles, upper ones about twice their length. Racemes terminal, several-flowered, nodding before expansion, afterwards lengthening out and becoming erect. Brac- tes lanceolate, somewhat falcate, fringed with long hairs.

Calyx of 5 sepals ; the two outer ones small, oblongly lanceolate, spreading, and fringed : the three inner ones ovate, concave, membranaceous, acute, strongly 3-nerved, the nerves very prominent, and clothed with bunches of hairs, that are seated on little tubercles. Flowers white, very double, a great number of the stamens being turned into petals. Our drawing of this pretty double variety, was taken from a plant at the Nursery of Mr. J. Lee, at Ham- mersmith ; it is quite as hardy as the single variety, and is well adapted for growing in rock-work, or in small pots, mixed with the other species ; by cutting off the flower-stems as soon as the flowers are dropped, will in- crease the strength of the young shoots, and occasion them to push out other racemes of flowers in succes- sion ; so as to continue in bloom the greater part of the Summer: young cuttings, planted under hand-glasses in Spring or Autumn, will strike root readily. s// 36 HUDSONIA ericoides, Heath-like Hudsonia.

A short densely branched suffruticose plant, from a span to near a foot in height; branches erect, elongated, thickly clothed with leaves, and densely crowded to- gether. Leaves, like some species of Heaths, subulately linear, more or less imbricate, becoming more patent as they advance in age, and remaining persistent for 2 or 3 years ; thickly clothed with spreading white hairs, as is every other part of the plant, except the corolla; this gives the whole plant a sort of hoary appearance. Peduncles solitary, one-flowered, each proceeding from the side of one of the gemmae, or little tufts of leaves, with which the branches are crowded, and some of which afterwards lengthen out into shoots; when the flowers first expand, the peduncles are very short, but they continue to lengthen as the capsule is coming to perfection, until they are from 5 to 8 lines in length ; more or less tinged with brown, as is the calyx. Calyx tubular, 5-parted: segments very unequal, the three in- ner ones more than double the size of the other two, and obtuse, the two outer ones very narrow, and acute. Pe- tals 5, distinctly spreading, of a bright but pale yellow, obovately ovate. Stamens from 9 to 15, spreading when the flower first expands, afterwards closing round the style : filaments unequal in length, smooth, pale yellow, about the length of the style : anthers small, 2-lobed, the lobes distant and distinct, opening longitudinally : pollen golden yellow. Germen downy. Style erect, or slightly bent, smooth. Stigma simple, very small. This elegant little plant is at present very scarce in our collections, owing to its being supposed to be very difficult of cultivation ; but our present subject thrives very well, and grows quite luxuriant in a pot of sandy peat soil ; and would, we expect, still grow more lux- uriant, if planted out in a bed of sandy peat, in rather a shady situation, as it is said to cover large tracts of ground in America, in the sandy Pine woods, in the same manner as the common heath in England. H. ericoides of Nuttall, is, as M. Decandolle ob- serves, most probably quite a different species from the present plant, as he describes the flowers as growing in fascicles, and the present only produces them singly. Young cuttings, planted under hand-glasses in sandy peat soil in the open air, in August or September, will strike root, if the glasses are occasionally taken off to dry them, that they may not damp. Our drawing was taken from a plant, procured for us in flower by Mr. G. Charlwood, in July last. 57 HUDSONIA tomentosa. Tomentose Hudsonia.

DC. prodr. 1. p. 285. Hudsonia tomentosa. Nutt. gen. 2. p. 5. Spreng. syst. 2. p. 452. Swt. hort. brit. add. p. 469. A short, densely tufted suffmticose plant, about a span high : branches short, crowded, ascending, densely to- mentose, and thickly clothed with leaves, which are per- sistent, and remain on long after they are turned brown, so that the branches are always crowded with them. Leaves crowded, minute, scarcely a line in length, close- ly imbricated, oblong or ovate, acute, densely clothed with a white silky tomentum, which gives the plant a sort of silvery appearance. Flowers small, of a pale bright yellow, sessile or on very short footstalks, each seated on one of the little gemmae, or small tufts of leaves with which the branches are crowded, so that when they are expanded they appear in clusters. Calyx cylindrical, 5-cleft, clothed with a silky tomentum, the segments obtuse, two of them much smaller than the others. Petals 5, distinctly spreading, obovate, concave, longitudinally lined. Stamens from 10 to 18; filaments slender, smooth, longer than the style, but scarcely so long as the petals. Ovarium 3 -sided, smooth, and glossy. Style smooth, erect. Stigma simple. Our drawing of this rare plant was made in July last, at the Nursery of Mr. Colvill, where several plants of it have been lately received from North America ; it was first discovered by Mr. Nuttall, and described by him in his Genera of North American Plants, in 1818, where he notices it as a very distinct species, " growing Q on the drift sands of the o0ean, in New Jersey, Dela- ware, Maryland, &c." Tlie soil in which the plants came home was chiefly fin white sand, with a small admixture of decayed vegetable soil, so that to grow them in perfection in this country, it will be requisite to plant them in the same sort of soil, or in a mixture of light turfy peat and sandJto be composed chiefly of the latter; sea-sand, where it/can be procured, is to be pre- ferred : it will also be mire likely to succeed well in a situation near the sea, man in an inland part of the country. It is also a very proper plant for rock- work, if planted in the same sort of sandy soil, where its little bushy canescent tufts yill make a handsome appear- ance : young cuttings, ^lantod in the same sort of soil, under hand-glasses or bell-glasses, will strike root rea- dily, so that a little air be given them that they may not damp off; as soon as rooted, they should be potted off in small pots ; for if left under the glasses, they will certainly damp, being so densely clothed with pubes- cence ; or if not convenient to pot them offimmediately, a great deal of air must be admitted to them; and as soon as they are properly hardened, the glasses should be taken quite away/; when hardened in that manner, they may be taken u^ with little balls attached to them ; and when potted, if placed in a shady situation, they will need no other protection ; but if potted off as soon as rooted, they will require to be placed in a close frame for a few days, to make fresh roots, and must be har- dened to the air by degrees.
