striped with dark purple. Altogether a splendid plant, which will stand very well in a warm border, protecting it from the slugs, and from severe frost. Soil a light loam, mixed with a little peat or decayed leaves, and one half sand. Enothèra ròseo-álba; Onagràriæ. An annual. "One of the most beautiful species of the genus, and thrives well in the open border." Supposed to be a hybrid production, produced in the German gardens.

No. LXVIII. for October, contains

269 to 272.- Rheum (from the river Rha, now the Volga, beyond which grows a root bearing its name, much renowned in medicine, according to Dioscorides; from rheo, to flow, in allusion to its medicinal qualities, according to Linnæus) austràle; Polygoneæ. The leaves are heart-shaped, large, their margin set with little red glands; the flowers are of a blood-red, as are the seed-vessels; and, from these circumstances, it is easily distinguished from every other species of the genus yet known. Dr. Wallich, of Calcutta, first transmitted seeds of this species to England; from which plants were raised by A. B. Lambert, Esq., of Boyton House, and flowered in June, 1828. Mr. Don and Mr. Sweet consider it "undoubtedly the handsomest species of the genus," independently of " the interest attached to it as a medicinal plant." The following description is by Mr. David Don :

"The stem in the cultivated plant is from 7 to 10 ft. high; the leaves are numerous, ample, and of a grassy green; the flowers are smaller than in any other species of the genus, of a dark or blood-red colour, and dis. posed in many branched clusters; the seeds that afterwards appear are dark red, with a highly polished surface, resembling, at a distance, clusters of glittering beads. When bruised, they emit a powerful odour of rhubarb, are highly astringent, and dye the fingers red, from the quantity of colouring matter contained in the testa. It is perfectly hardy, and appears to ripen its seeds even more copiously than the other species; and, from some trials that have been made with the footstalks of the leaves, it seems disposed to vindicate its medicinal claims even in our own climate. The colour of the flowers would alone be sufficient to distinguish it among its congeners. The late period of flowering deserves also to be remarked. As all the species are endowed, in a greater or less degree, with similar properties, much difference of opinion has arisen, both among botanists and pharmacologists, respecting the one that yields the rhubarb of commerce. Linnæus considered it at first as the produce of his R. Rhabarbarum or undulatum, but he afterwards appears to have altered his opinion in favour of R. palmatum; which opinion has been almost universally adopted by pharmacological writers, although it is admitted that the qualities of the root of R. palmàtum differ materially from the Turkey rhubarb of the shops: but this deterioration has been attributed to the difference of soil and climate. The R. austràle appears to be peculiar to the great table lands of central Asia, between the latitudes of 31° and 40°, where it is found to flourish at an elevation of 11,000 ft. above the level of the sea. Large quantities of the roots are annually collected for exportation, in the Chinese provinces within the lofty range of the Himalaya. The best is that which comes by way of Russia, as greater care is taken in the selection; and on its arrival at Kiachta, within the Russian frontiers, the roots are carefully examined, and the damaged pieces removed."

Mr. Sweet has been " informed that the stems of the leaves have the same effect as the root; only, of course, a greater portion of them will require to be used. They may be made up in a small tart, like the stems of the common rhubarb." Culture as in the other species, covering the roots a little in very severe winters.

by the twisting of the footstalks of the leaves; the leaves are peltate, and so deeply divided, as at a distance to resemble those of the common lupine; the flowers are numerous, axillary, of a glossy scarlet orange colour, with a circle of dark purple, nearly black, round their margin. Altogether, it is one of the most beautiful and interesting climbers that have been introduced to this country for some time; and we have no doubt its tuberous roots, about the size of beans, will be as much in demand for planting close to bowers and verandas, as those of crocuses are for beds and borders. "Some roots of the present, and another species, were presented to Mr. Anderson by Miss Oriana Georgiana Reinagle, who received them from Miss White, daughter of the Vice-Consul at Valparaiso." We hope Mr. Sweet will take the first convenient opportunity of dedicating a genus to each of these young ladies. - Salpiglóssis atropurpurea; Solàneæ. Perennial, or perhaps biennial; the leaves elliptically oblong and sinuated; the flowers large, dark purple, sometimes nearly black, and orange-coloured in the throat; they vary considerably in size, according to the soil and situation. A light rich soil, a warm border, with a little protection in winter; propagation by cuttings under hand-glasses, or by seeds which ripen plentifully.

Taxanthema (taxis, arrangement or order, anthemos, flowery; flowery arrangement of the spikes) incàna; Plumbagineæ. Perennial; lanceolate leaves, and small flowers, varying from dark red to nearly white. Very handsome, and of easy culture in rich loamy soil, rather sandy.

No. LXIX. for November, contains

273 to 276.- Cyclobóthra barbàta; Tulipace. Bulbous-rooted, with very long leek-like leaves; stem slender, leafy, and about a foot high; and the flowers of a golden-yellow colour, and nodding. Iris tridentàta; Irídeæ. A very handsome and singular species, from North America, with purple flowers; at present rather scarce, but thrives well in the open border of the garden; pretty readily increased by divisions of the root. - Echevèria grandifòlia; Crassulaceæ. This magnificent plant is a native of Mexico, suffrutescent and succulent, with thick, smooth, blue leaves; stalk upwards of 5 ft. high, and flowers variegated with orange, purple, and blue; the leaves, though they appear firm, come off easily. It flowers abundantly in a light sandy soil by the side of a wall in a southern aspect, and covered by a mat in frosty weather.-Hunnemannia (" We have named it in compliment to our friend, Mr. John Hunneman, who, through his numerous correspondents in various countries, has been the means of introducing a greater number of plants to our collections than almost any other individual; and we are somewhat surprised that a genus has never been named after him before." We agree with Mr. Sweet in wondering that no one has before dedicated a genus to Mr. Hunneman; and the only way of accounting for it that we can think of is, that botanists have felt that the long and unremitted services rendered by him to science and scientific men, have been too serious to adinit of the light and ordinary idea recurring to them, of rewarding these services by a compliment. There is not a botanist or reading gardener on the Continent or in this country to whom the name of Hunneman is not familiar; and by far the greater number of the former are under personal obligations to him, for transmitting them seeds, speeimens, or books. We, of course, include ourselves among the number, and take this opportunity of acknowledging the services which we are continually receiving at his hands.) fumariæfòlia. An erect branching-stemmed plant, with linear leaflets, and large spreading flowers of a golden-yellow

colour. It was raised in the collection of Robert Barclay, Esq., of Bury Hill, from seeds received from Mexico.

No. LXX. for December, contains

277 to 280.- Hibiscus ròseus. A perennial from Italy, with large rosecoloured flowers, upon stems from 3 to 4 ft. high, but " requiring to be grown in some moist situation, otherwise it will not be likely to flower. Moricándia arvénsis; Cruciferæ. Biennial, with glaucous obovate leaves, and elegant purple lilac flowers. From the south of Europe in 1739, but rarely to be met with in our gardens. From the Epsom nursery.-Potentílla Russelliana. (fig. 37.) "The present splendid-flowering plant is of hybrid origin, being intermediate between P. formosa and P. atropurpurea, varying with leaves containing three, four, and five leaflets. It was raised from seed last year, by Mr. W. Russell, at his nursery at Battersea, who has employed a great deal of time with the plants of this genus, to try to obtain something handsome from them; and his labour has been so far crowned with success in obtaining the present handsome plant, which may be considered as one of the most splendid hardy perennial plants that need be cultivated in the open borders of the flower-garden, and is well deserving a place in every collection. Neither of its parents can come near it in brilliancy of colour, which is of a glossy scarlet. It is quite hardy, and thrives well in the open borders in the common garden soil, and may be increased by dividing at the root, but is not likely to ripen seeds,

as the anthers are mostly all without pollen; so that it is not likely soon to become common. Mr. Russell has already increased it, and informs us that he is now selling the plants at one guinea each." - Campánula dichótoma. Annual, with nodding purplish blue flowers; very pretty, and quite a distinct species, lately introduced from Greece to Bury Hill.

281 to 284. - Heímia salicifolia. (fig. 38.) A handsome little bushy evergreen shrub, with yellow flowers. It is a native of Mexico, and has been cultivated several years in the botanic garden at Berlin. Warm border, and a little protection in winter. Georgina* (J. G. Georgi, a Russian botanist, author of various works, among others, A Description of St. Petersburg, 8vo, 1723) crocàta; Compósitæ. The Dáhlia fúlgens of gardeners.Lupinus canaliculàtus. Frutescent, handsome, and stately; raised at Bury Hill, but its native country at present unknown. Lobèlia Tupa. Perennial, somewhat frutescent, sessile woolly leaves, and scarlet flowers tinged with orange. From Mr. Lambert's garden at Boyton, where it grows 10 ft. high, and, though a native of Peru, is quite hardy. "The juice of the present plant is said to be very poisonous, which, we believe, is more or less the case with those of the whole genus.'

This is Willdenow's name for the Dáhlia, and Mr. Sweet very properly prefers it; because, unknown to Willdenow, a Cape genus had been named Dáhlia by Thunberg. Thunberg's genus, therefore, had the right of priority; in consequence of which Decandolle, Kunth, and most of the Continental botanists, have adopted the name of Georgina. As this change is unques

285 to 288.- Podólepis (pous, a foot, lepis, a scale; footstalks to the scales of the involucrum) grácilis; Compósitæ Carduàceæ Astèriæ. “A very pretty plant, from New South Wales, to the garden of Robert Barclay, Esq., of Bury Hill, quite as hardy and of as easy culture as the common annual Everlasting." Hibiscus Moscheùtos; Malvàceæ. Beautiful; from the collection of A. B. Lambert, Esq., at Boyton House. "It is seldom that the present plant, or H. palústris, produces flowers in our gardens. The reason is, without doubt, through their being planted in too dry a situation, their native places of growth in America being in swamps and marshes. Pursh mentions the present species as growing in swamps and salt marshes, from New York to Carolina, and plentifully in the marshes round the Salt Lake, Onondago, New York; flowering from August to October." It is most probably owing to the very wet summer that they flowered so freely this season, and by being planted in a moist situation; and there can be no doubt but they would flower as readily every season if planted near a pond, or in any wet swampy ground. They are quite hardy, and are readily increased by dividing at the root, or by seed. Gília capitàta; Polemoniaceæ. One of the interesting discoveries "made by our indefatigable friend, Mr. David Douglas, in the north-west regions of America. It is quite hardy, and forms a valuable addition to the flower border, which it adorns during the summer months with its numerous tufts of pretty blue flowers." It is annual; but, if sown at different seasons, between March and August, a succession of flowers may be kept up all the summer and autumn.- Dianthus gigantèus; Caryophylleæ Silèneæ. A gigantic species, from the nursery of Messrs. Young, of Epsom, and raised there from seeds received from Malaga.
