An erect, branched shrublet 0.3-0.5 m tall with ascending slender branches sparsely to densely tomentose on the young parts. Leaflets linear, needle-like (1-)3-7 mm long and 0.3-0.4 mm thick, subterete, straight or very slightly incurved, glabrous, green, acute-acuminate. Inflorescence a terminal head-like umbel with up to 5 flowers or flowers sometimes solitary on the branch tips or solitary on short, lateral branchlets or on lateral short-shoots, or a combination thereof. Flowers small. Bract situated on the pedicel 0.4-0.9 mm from its base, linear, 0.7-1.7 x ±0.2 mm, acuminate, glabrous on abaxial side, ± puberulous on the adaxial side. Pedicel 1-2 mm long, puberulous. Bracteoles linear, 0.5-0.8 mm long. Calyx tube ±2 mm long, subglabrous or sparsely puberulous; lobes subulate, 0.7-1.5 mm long, subterete, green, glabrous or subglabrous, acute-acuminate, often apically incurved. Petals light yellow. Standard blade 4.7-5.4 x 3.8 mm, glabrous, except at the base; apex acute. Wing blades 3.7-4.4 x 1.4-1.8 mm, glabrous, with ±3 rows of minute folds on the basal parts. Keel blades 4-4.7 x 2.3 mm, obtuse(-subacute), glabrous, with slightly concave upper margin and prominent basal pouch. Pistil almost glabrous but with some pubescence on upper basal parts of the ovary; ovules 2. Pod triangular-lanceolate, 10-12 x 3.8-4.1 mm, often with marked transverse folds, subglabrous, brownish black, glossy.
