Leaves: Alternate, pinnately compound, 2-10 cm long, short-stalked to unstalked; leaflets 7-15, linear-oblong to lanceolate or elliptic, 7-25 mm long, hairy on both surfaces or glabrous above; stipules egg-shaped to oblong, 3-8 mm long, the lower ones joined and clasping the stem, the upper ones free.
Flowers: Inflorescence a short, axillary raceme of 6 to 30 spreading, pea-like flowers, the racemes compact at first, later elongating, 2-12 cm long on stalks that exceed the leaves; corollas yellowish-white, often tipped or tinged with purple, the banner longer than the wings, which are notched at the tip and slightly longer than the keel; calyces 4-7 mm long, usually black-hairy, the awl-shaped teeth from 1/2 to nearly as long as the bell-shaped tube.
