A small, suberect shrublet, up to ±0.3 m tall with spreading, rigid, straight branches arising from a short stem. Young branches straight, but not thorny, short-villous; lateral branchlets successively shorter towards the branch tip. Leaflets linear, vermiform, 0.6-2 mm long, ±0.4 mm thick, terete, often slightly incurved, glabrous, obtuse. Inflorescences unifloral, on lateral short-shoots, often several on each branchlet. Flowers small. Bract situated on the middle part of the pedicel, tooth-like, 0.4-0.7 mm long. Pedicel 1.2-2 mm long, densely puberulous. Bracteoles tooth-like, ±0.22 mm long. Calyx tube puberulous; lobes subglobose-ovoid, ±0.6-0.8 mm long, about equally broad, carnose, subterete, obtuse to acute, green, subglabrous. Petals light or bright yellow, becoming reddish, subglabrous or glabrous. Standard blade 4.5-5.2 x 3.3-4.5 mm; its apex strongly incurved (almost hood-like), the sides ± incurved. Wing blades linear or very narrowly ovate, 3.2-3.5 x 1.3-1.5 mm, glabrous, with 2-3 rows of minute folds on upper basal half or more. Keel blades 3.5-4 x 1.6-1.8 mm, glabrous. Pistil sericeous on upper parts of the ovary and ciliate above on the style base; ovules 2. Pod broadly triangular-lanceolate, ±4.2-2 mm, sparsely tomentose or sericeous on most parts.
