An ascending or erect, more or less closely branched shrub 0.2-0.5 m tall, with rather slender, non-thorny branches; young branches short-villous (patent-puberulous). Leaflets linear-subulate, 2.5-5 mm long, 0.4-0.6 mm thick, subterete or ± angular, often slightly recurved, acute to mucronulate, bright green, glabrous or with sparse, scattered hairs. Flowers rather small. Bract linear, (1.6-)2.2-4.2 x ±0.3 mm, straight or slightly incurved, green, pointed, glabrous abaxially, short-pubescent adaxially. Pedicel 0.5-1 mm long, short-pubescent. Bracteoles (1.7-)2-5 mm long. Calyx tube with sparse, spreading, tomentose pubescence; lobes subulate, 1.8-3.6(-4) mm long, green or purplish, glabrous or subglabrous, acute-acuminate. Petals bright yellow, orange or generally becoming ± ferruginous; claws rather short. Standard blade circular, (4.6-)5-7.5(-8) x 5.3-8.5 mm, apically retuse but usually with a little 'tip', with distinct basal lobes, sericeous (-tomentose) on the back. Wing blades narrowly ovate-elliptic, (3.3-)3.8-5.5 x (1.5-)1.7-2.5(-2.8)mm, glabrous. Keel blades 4.1-6 x 2-3 mm, glabrous, with slightly concave upper margin. Pistil pubescent on upper and apical parts of the ovary; ovules 2. Pod broadly and obliquely lanceolate, 6-6.5 x 2.7-3 mm, pubescent on most parts.
