Annual herbaceous plant, 6–30 cm high, sterile stems prostrate; flowering stems ascending from decumbent base, or sub-erect–erect, sparsely villous hairy in lower part and densely villous hairy in upper part. Stipules ovate–lanceolate, 3– 6× 2–4 mm, entire, denticulate at apex. Leaves trifoliolate. 10–30 mm long. Petiole 10–23 mm, densely villous. Leaflets obovate–cuneate, dentate in upper part, densely villous, 2.5–9.0× 2–9 mm. Petiolule 0.8–1.2 mm long. Inflorescence 15–25 flowered, dense, capitate to oblong-cylindrical, 8–20× 7–13 mm in flower, 12–22× 10–16 mm in fruit. Peduncle 6–30 mm long and densely tomentose. Pedicel up to 0.5 mm long and tomentose. Bracts lanceolate, narrowly acute, 3–5×0.5–1.0 mm, villous hairy. Calyx tubular, densely villous–tomentose, 6–7 mm long; teeth subulate, 2.5–3.0 mm long, shorter than tube. Corolla blue, standard spatulate-shaped, emerginate at apex, 10–12×2.5–3.0 mm; wing narrowly rounded, ±spatulate, rounded at apex, 8.5–9.0×1.0– 1.5 mm; keel elliptic-shaped, obtuse at apex, 9–12×3.0– 3.5 mm. Androecium 7.5–8.0 mm and gynoecium 9.5–10.0 mm long. Legume oblong-lanceolate, 10–12× 2.5–2.7 mm (except beak), 13–15 veined; beak 2–6 mm long.
