A low, densely branched, procumbent to prostrate shrublet; main branches thick, basally sometimes up to more than 10 mm in diameter. Young branches short-pubescent (tomentose-sericeous), closely leafy. Leaflets linear to sub-filiform, 2.5-5 mm long, ±0.3 mm thick or less, subterete, slightly incurved, obtuse or subacute, weak, short-sericeous (rarely glabrous). Flowers small, inconspicuous, solitary on lateral short-shoots, scattered along the branches. Bract not or only slightly fused with the pedicel, small, oblong, 0.3-0.5 mm long, puberulous. Pedicel 1-1.5 mm long, short-pubescent. Bracteoles tooth-like, 0.2-1.8 mm long, silky sericeous (rarely glabrous). Calyx tube campanulate, sericeous; lobes sharply demarcated from the tube, linear-subulate, 1-1.9 mm long, sericeous(-glabrous). Petals light or bright yellow or standard partly purple. Standard blade 3.2-4.6 x 2.7-4.3 mm, rounded-obtuse, puberulous on apical half of back, otherwise glabrous. Wing blades 1.8-3 x 0.9-1.4 mm, glabrous, with ±4 rows of minute folds on upper parts.
