variably pubescent with reflexed hairs; leaflets ovate or oblong, obtuse or mucronate, appresso-pubescent or silky; peduncles longer than the leaves, interruptedly many-flowered; upper lip of the calyx deeply bifid; vexillum narrowed at base; alæ unidentate, longer than the obtuse carina; legume appressedly hispid or glabrescent. Stems slender; in our specimens rough with reflexed, fulvous, rather rigid hairs, sometimes glabrescent. Petioles 1–2 inches long. Leaflets 1–1 1/2 inch long, 3/4–1 inch wide, varying from sparsely hispid to densely silky, the hairs appressed. Racemes 3–4 inches long, the flowers minute, 2–3 together in tufts, 3–4 lines apart, silky pubescent or subvillous. Calyx 2 lines long, the segments subequal, the two upper broader, connate at base or nearly to the middle. Vexillum 3 lines long, obovate, with a long, tapering claw. Legume 1 1/2–2 inches long, 1 1/2 line wide, linear, slightly falcate, with a thick, incurved style and 10–12 transverse seeds, separated by cellular septa.
