MIMOSA inermis, foliis bipinnatis, multijugis, ciliatis; racemo composito terminali. Acacia grandiflora. _Willd. Sp. Pl. 4. p. 1074._ MIMOSA unarmed, with doubly-winged leaves in many pairs and ciliated, and flowers in a compound terminating bunch. REFERENCE TO THE PLATE. 1. The empalement. 2. The chives spread open. 3. The pointal. * * * * * This species, conspicuous by its tall woody stems, large purple blossoms, and delicate foliage, was brought to the Royal Gardens at Kew from India by Mrs. Norman, about the year 1769. It is a plant of quick growth, and blossoms freely, but has never produced any pods in this country. The only figure of it we have seen is that by Reinagle in Dr. Thornton’s Illustration of the System of Linnæus. A plate however was finished for L’Heritier, who first described it; but his death prevented its publication. The stamens (as in many other Mimosas) are united near the base. The blossoms open in succession from the bottom of the bunch upwards, and continue great part of the summer. The leaves are deciduous. The specimen was communicated from Boyton by A. B. Lambert, esq. in August. [Illustration] PLATE DXCIII. CROTALARIA TETRAGONA. _Four-sided Crotalaria._ CLASS XVII. ORDER IV. _DIADELPHIA DECANDRIA._ Two Brotherhoods. Ten Stamens. ESSENTIAL GENERIC CHARACTER. LEGUMEN pedicellatum, turgidum. Stamina omnia connexa. POD on a stalk, swollen. Stamens all connected. SPECIFIC CHARACTER. CROTALARIA caule tetragono, strigoso; petiolis brevibus, foliis oblongo-lanceolatis, acuminatis; stipulis caulem amplexantibus. CROTALARIA with the stem 4-sided, with flat pressed hairs: short footstalks: leaves oblong-lanced, and pointed: stipules embracing the stem. REFERENCE TO THE PLATE. 1. The keel. 2. The chives and pointal. 3. Seed-bud and pointal. * * * * * This new and very ornamental species is remarkable for having the under lip of the calyx often undivided, and every part of the plant up to the blossom covered with shining close-pressed hairs: nor are they entirely wanting on the blossom; on the lower part of the keel they are very conspicuous, hanging downwards like a little beard. A groove with a fringe on each side runs also along the upper side of the style towards the summit. Two thread-shaped silky stipules rise at the base of every leaf-stalk, and, being reflected backwards, closely embrace the stem. A solitary stipule also rises at the base of each flower-stalk, and two where it unites with the calyx: but these, from their singular situation, must perhaps be considered as bracteæ.
