An erect spreading shrub up to at least 0.4 m tall, with divaricate, rigid, straight, strong branches ending in pungent thorns. Young branches, thorny or not, light brown or reddish, partly puberulous. Short-shoots usually not developed in leaf axils of young branches. Leaflets flat, spathulate-oblanceolate, 3-12 x (0.6-)2-3 mm, apically rounded(-subacute), green, sparsely appressed-puberulous, with very slightly elevated midvein. Inflorescences unifloral, in leaf axils (representing axillary short-shoots). Flowers long-pedicellate, small, inconspicuous. Bract visible in the middle of the pedicel, tooth-like, 0.3-0.5 x 0.2 mm. Pedicel 2.5-4.5 mm long, densely puberulous. Bracteoles tooth-like, 0.1-0.2 mm long. Calyx tube infundibular-campanulate, sparsely appressed-puberulous to subglabrous; lobes obsolete or very short, triangular, 0.4-0.7 mm long, subacute, subglabrous. Petals light yellow or partly or entirely pale purple. Standard blade 5-5.3 x 3.7-4.4 mm, obtuse but with a 'tip', puberulous on the base and along the midrib of the back, otherwise glabrous. Wing blades very narrowly elliptic or linear, 3.7-4.6 x 1.2-1.4 mm, glabrous, with 1-3 rows of (several) minute folds on upper basal part, upper margin not or only slightly incurved. Keel blades 3.7-4.2 x 2.1-2.4 mm, glabrous, broadest 1/4 from apex. Pistil: ovary and style base short-sericeous; ovules 2. Pod triangular-lanceolate, 8-9 x ±3 mm, sparsely short-sericeous.
