Perennial, procumbent; 2–5 cm, acaulescent to shortly caulescent. Stem when present up to 2 cm long, densely covered with unequally bifurcate white and black hairs, black hairy stripes surround the stem below the nodes, and woody caudex branched. Stipules 9–13 mm long, triangular to narrowly triangular, acuminate at the apex , base shortly connate around the stem and attached to the petiole with 1/4–1/2 of its length, acumens free, densely covered with spreading black and/or white ± sub-bifurcate hairs, sometimes also with dense black hairs near the base, internodes prominent 1.0–2.0 cm long. Leaves 2.5–4.5 cm long, mostly longer than peduncles. Petiole 10–15 mm long, appressed to sub-spreading hairy. Leaflets in 7–9 pairs, narrowly elliptic, acute at the apex, mostly folded, 5.5–9 × 2.5–3.5 mm, on both sides densely covered with dense silvery subadpressed to spreading unequally bifurcate white hairs , also some black bifurcate hairs at the lower part of the leaflets. Peduncles 2–4 cm long, erect, as long as or shorter than leaves, densely sub-bifurcate , black and white hairy. Racemes globose to ovoid, dense, 20–30 flowered spike, 3 × 3 cm, not elongating in fruit. Bracts 13–15 × 0.4–0.5 mm, linear-lanceolate, membranous, covered with long spreading, dense white and sparse black sub-bifurcate hairs. Bracteoles absent. Pedicels up to 1 mm long. Calyx 13–14 mm long, campanulate-tubular, covered with mostly dense and long spreading sub-bifurcate white hairs, rarely with also shorter sparse black hairs at base of tube, and with very few short white and black sub-bifurcate hairs; calyx teeth 7–9 mm long, linear, longer than calyx tube, spreading sub-bifurcate, dominantly white and also black hairs. Corolla white to cream . Standard 22–23 × 8 mm, rhombic-obovate, emarginate at the apex, without clearly differentiated claw, gradually narrowed at the base, glabrous. Wings 15–16 mm long , glabrous. Keel 12–13 mm long , glabrous. Ovary ± stipitate, elliptic, white hairy. Legume 6–7 × 1.5–3.0 mm, narrowly elliptic, ± stipitate with a straight beak 3–4 mm long, bilocular with 4 seeds in each locule, densely covered with appressed to subappressed white sub-bifurcate hairs. Seed reniform–globose , color dark greenish brown.
