Plants procumbent; stem 3–15 cm long, with symmetrically to asymmetrically bifurcate hairs, branched from base, and a woody caudex enclosed by remains of old stipules. Stipules 3.0–3.5 mm long, ovate, acute, densely appressed white, ± bifurcate hairy, black ciliate on the margin, free from petiole, vaginate–connate behind the stem, overlapping internodes. Leaves 0.5–2.0 cm long, shorter than peduncles; petiole 1.0–1.5 mm long, appressed hairy. Leaflets linear-oblong, 1–2 × 0.3–0.5 mm, on both sides densely covered with appressed bifurcate hairs, in 4–7 pairs. Peduncles 1.0–1.5 cm long, as long as, shorter or longer than leaves; densely covered with appressed white and black hairs. Racemes globose, 5–15 flowered, ± elongating in fruit. Bracts 1–2 mm long, ovate-acuminate, membranous, covered with spreading white hairs on dorsal surface and black ciliate at margin. Pedicels to 1 mm long, hairy. Calyx 7–9 mm long, tubular, densely covered with sub-appressed white and loosely appressed black hairs; teeth 0.5–1 mm long, linear, with dominantly black hairs. Corolla violet. Standard 15 mm long, slightly emarginate at apex, covered with appressed white hairs on upper side. Wings 11–12 mm long, glabrous. Keel 8–9 mm long, covered with appressed white hairs on dorsal surface. Stamen-tube obliquely cut at the mouth. Ovary ± sessile, ellipsoid, hairy. Legume 4–5 × 3–4 mm, ovoid, ± sessile with a curved beak 2–3 mm long, bilocular with 1–2 seeds in each locule; valves densely covered with spreading white hairs.
