It is properly a hardy green-house plant: requires a light soil, and the treatment of an Ixia: increases both by offsets from the root, and by seeds: and flowers annually in the months of January and February. The leaves die down in April or May. In the structure of the flowers, but not the spathe, it agrees with Allium gracile of this work, which is not the gracile of the Hortus Kewensis. The genus Allium is an extensive one; but the present is the least species in it, and possesses the shortest stalk. Cavanilles describes and figures the style as subulate and entire; but in our plant that part is forked: and the spathe in his plant differs much from ours. [Illustration] PLATE CCCLXXVIII. GERANIUM FISSIFOLIUM. _Cloven-leaved Geranium._ CLASS XVI. ORDER IV. _MONADELPHIA DECANDRIA._ Threads united. Ten Chives. ESSENTIAL GENERIC CHARACTER. MONOGYNA. Stigmata quinque. Fructus rostratus, pentacoccus. ONE POINTAL. Five summits. Fruit furnished with long awns, five dry berries. SPECIFIC CHARACTER, &C. GERANIUM, radice tuberosa, pinnulis foliorum inæqualiter fissis, scapis radicalibus simplicibus numerosis. GERANIUM, with a tuberous root, the little wings of the leaves unequally cloven, and flower-stalks radical simple and numerous. REFERENCE TO THE PLATE. 1. The empalement. 2. The chives spread open. 3. The pointal and seed-bud. 4. The same magnified. This charming species of the tuberous-rooted family of Geranium adds one more to the considerable number in that branch of the genus, which we have already had the satisfaction of laying before our subscribers: nor is it the last we hope to have it in our power to treat them with; for we still possess drawings of two or three more. As a species, it is extremely distinct; and as a beauty, rivalled by very few of its affinities we are acquainted with. It does not appear to have been noticed by any author within our knowledge; flowers at the same time as Geranium barbatum, requires the same treatment, and belongs to L’Hertier’s genus Erodium. Our drawing was taken from the Clapham collection some time since; but we cannot at present procure any specimen of it: which prevents us from describing it in a technical manner.

SPECIFIC CHARACTER, &C. RHODODENDRON, foliis lanceolatis deciduis, laciniis corollæ valde undulatis. RHODODENDRON, with lanced deciduous leaves, and segments of the corolla very much waved.
