A twining Shrub, the stem of which sometimes exceeds the 

 thickness of a man's arm, and is covered with rough brown 

 bark. The larger branches are often flattened, and sometimes 

 two are combined together. On the year-old branches, the 

 flowers are produced. The ramuli of the season are terete, 

 green, and villous. Petioles long, slender, usually coloured, 

 pubescent, swollen at the base, the swollen part covered with 

 ferruginous hairs. Leaves ternate : leaflets petiolulate, ellip- 

 tical-ovate, triplinerved, reticulated, entire, hairy, especially 

 beneath on the ribs, hairs deciduous; the lateral pair 

 externally dilated. Stipules of the leaflets subulate. Pe- 

 duncles axillary or springing directly from a branch, shorter 

 than the petioles, and bearing, near the extremity, five or 

 six large round buds, each producing three flowers, all form- 

 ing together a large, globose, compound raceme or thyrsus. 

 Calyx campanulate, 4-toothed, teeth j, covered with stifi^, 

 rusty hairs. Corolla papilionaceous ; Vexillum short, obtuse, 

 embracing the base of the wings and keel; Wings linear- 

 oblong, bent upwards near the point, and united; Keel 

 very long, straight, except near the point, where it 

 bends suddenly at nearly a right angle, and terminates in a 

 sharp hooked point : the petals of the keel are united along 

 the edges, both above and below, hence the stamens and 

 pistil are completely enclosed, as it were, in a bag. Stamens 

 diadelphous; the very long free portions of the filaments 

 alternately longer and shorter ; the longer bearing rounded 

 hairy anthers; the shorter, more slender, oblong, linear, 

 glabrous ones. Pistil: Germen compressed, very hairy; 

 Style equal in length with the stamens, villous ; Stigma simple. 

 Legume between reniform and orbicular, 2-valved, 1-celled, 

 1 -seeded, very deeply furrowed and lamellated on the sides 

 and edges, and beset with innumerable stiff" ferruginous very 

 fragile hairs, which readily penetrate the skin, and cause 

 much irritation. Seed solitary, corresponding in form with 

 the legume, and circumscribed by a linear scar.
