Inflorescence a loose to compact, axillary raceme of 3 to 20 more or less spreading, pea-like flowers, the racemes 1-10 cm long on slender stalks from shorter to longer than the leaves; corollas 8-12 mm long, from white or yellowish to bluish, the banner and wings with blue to pinkish-purple pencilling, the banner slightly longer than the wings and the purple-tipped keel; calyces 3-6 mm long, white or black appressed-hairy, the teeth triangular-awl-shaped, about 1 mm long.
Pods, narrowly oblong, nearly unstalked, drooping, glabrous to hairy, 1.5-2.5 cm long, flattened or not, becoming papery, 1-chambered.
