branches sharply angular, or slightly winged; leaves narrow-oblong, or cuneate-oblong, obtuse, mucronate, thick and veinless; peduncles axillary, one flowered, bibracteate at base, deflexed after flowering; calyx lobes separate, twice or thrice as long as the tube, and as long as the carina, the four upper ones lanceolate-acuminate; legume oblong-cultrate, cuneate at base. 1 1/2–2 feet high, many stemmed, simple, or branched from the base; branches virgate, curved, sub-trigonous or compressed. Leaves scattered, 1–2 inches long, nearly 1/2 inch broad, tapering more or less to the base, of a thickish substance, one nerved, but without obvious veins, more uniform in shape than in most species. Peduncles an inch long, shorter than the subtending leaf, articulate about a line from their base, and there furnished with a pair of linear, leafy, long or short bracts. Corolla scarcely protruding beyond the attenuated calyx lobes; keel rostrate. Legume pendulous. This seems to me to be a well marked species.
