Leaves:
Basal (a few) and alternate along the stem, palmately compound, the stalks of the basal leaves often much longer than those of the stem leaves; leaflets 9 to 17, elliptic-oblanceolate, pointed at the tip, 3-12 cm long, glabrous above, sparsely stiff-hairy below.
Flowers:
Inflorescence a dense, stalked, terminal raceme, up to 40 cm long, of whorled or somewhat scattered, pea-like flowers; corollas bluish to violet, glabrous, 11-16 mm long, the banner nearly circular and slightly shorter than the wings; calyces about equally 2-lipped, both lips entire or minutely toothed.
Fruits:
Pods, curved, densely long-soft-hairy, 3-5 cm long; seeds 6 to 10, greyish with dark mottling.
