An erect ascending shrub, 0.3-1 m tall, sparingly branched. Young branches densely short-villous; short-shoots on villous tubercles. Leaflets linear, 3-8 mm long, rather thick, subterete or slightly flattened with ± distinct groove on adaxial as well as abaxial side, ± incurved, pale green, acute, apiculate or obtuse, appressed-puberulous or almost glabrous (glabrescent). Inflorescences unifloral or up to trifloral (the flowers then close together) on lateral short-shoots, these dispersed in considerable number along the branches. Flowers rather small and pale. Bract broadly subulate, 0.3-1.5 mm long, puberulous. Pedicel 1.0-2.8 mm long, densely puberulous. Bracteoles 0.1-1 mm long. Calyx densely and smoothly puberulous-sericeous; lobes broadly subulate, 0.4-2.5 mm long, acute, puberulous. Petals pale or light yellow, with claws less than half the length of the blades. Standard blade ovate, 5.5-7 x 4-5.8 mm, apically incurved and acute, short-sericeous on apical (-central) parts and on the base, ± glabrous at least laterally on basal parts. Wing blades 3.5-5.5 x 1.5-2.3 mm, glabrous (or with few hairs on apex and/or base), with ±4 rows of minute folds on upper half. Keel blades 3.8-5.7 x 2-3 mm, glabrous, obtuse, with ± straight upper margin. Pistil short-sericeous on most parts of ovary and upper side of style (basal half); ovules 2. Pod 6-7.5 x 2.7-3.7 mm, sericeous on most parts, smooth, brownish when ripe.
