Herbs or subshrubs, usually multi-stemmed, 0.2–1.2 dm. Stems decumbent to erect, densely pubescent, hairs spreading. Leaves subsessile; blade elliptic or obovate, 6–20(–26) × 3–10(–12) mm, base cuneate, apex acute or obtuse, surfaces pubescent, hairs spreading. Racemes terminal, sometimes leaf-opposed, 1–3.5 × 1.5–2.8 cm; rachis weakly thorn-tipped (often not clearly visible when young); peduncle 0–0.5 cm; bracts semipersistent, lanceolate to linear. Pedicels 3–7(–8.6) mm, pubescent. Flowers pink and white, sepals pink or brownish pink, margins white, keel beak yellow to yellow-green, (7.5–)8.5–13(–14) mm; sepals persistent, elliptic or ovate, (3–)3.5–6(–7) mm, glabrous or sparsely pubescent; wings narrowly elliptic to obovate, (7.2–)8–11.5(–12.3) ×3.2–5.6 mm, glabrous or sparsely pubescent; keel (6.5–)7.2–10.7 mm, sac spreading-pubescent in distal 1/2, sometimes also proximally, beak oblong, (1.6–)1.9–3.2 × (0.5–)0.7–1 mm, pubescent. Capsules ellipsoid, 4.8–8.5 × 4–5.7 mm, base obtuse or rounded, margins with very narrow wing, sparsely pubescent. Seeds 3.5–4.8 mm, pubescent; aril 0.8–2.6 mm, lobes 0–1/2 length of seed. 2n = 18.
