Herbs, shrubs, or subshrubs, single or multistemmed, rhizo­matous, sometimes spread­ing to form ground cover or thicket, 1–25 dm. Stems erect to sprawling or decumbent, sometimes glaucous, glabrous or sparsely pubescent, hairs incurved. Leaves petiolate, petiole 0.5–5 mm; blade linear to ovate, 10–50 (–65) × (3–) 4–11 (–16) mm, base cuneate to rounded, apex acuminate to rounded, surfaces glabrous or pubescent at least along basal midvein abaxially, hairs incurved. Racemes terminal, sometimes appearing axillary, 1–8 (–22) × 1.5–3 cm; rachis not thorn-tipped; peduncle 0.2–0.6 cm; bracts deciduous to subpersistent, lanceolate to ovate. Pedicels 2.5–11 mm, pubescent or glabrous. Flowers cream, greenish, or pink, keel distally rose, fading green, 7–14 mm; sepals deciduous, ovate, elliptic, or suborbiculate, 1.8–4.5 (–5.2) mm, pubescent; wings obovate to elliptic, (6–) 6.3–11 (–12) × (3–) 3.5–5.6 (–6) mm, usually pubescent, rarely gla­brous, margins ciliate; keel 7.5–10.2 mm, sac glabrous or sparsely pubescent, beak linear, entire, 0.5–2.5 × 0.2 mm, pubescent. Capsules ovoid to subglobose, 5.9–10.2 × 6–9.6 mm, base rounded to truncate or subcordate, margins with narrow, entire or slightly erose wing, glabrous, margins sometimes ciliolate. Seeds 4.5–7.3 mm, pubescent; aril 2–5.2 mm, lobes 1/4–1/2 length of seed.
