Racemes 4-8 cm long and 4-6 times as long as the flowering leaves, slender, with the peduncle below the lowest scar of fallen flowers longer than the leaves. Flowers lax, ascending in bud, spreading when open. Pedicels 2-4 mm long. Calyx-lobes scarcely 1 mm long, deltoid. Corolla 10 mm long; standard as seen in bud adpressed-pubescent with somewhat golden-brown hairs. Pods very young, apparently terete.
