Annual. Stems prostrate to erect, 5–30 cm. Herbage glabrous. Leaflets obovate, 5–15 mm long, serrate; stipules ovate, lacerate. Racemes axillary, umbellate, 1–2 cm wide, longer than the leaves, subtended by a glabrous, saucer-shaped involucre with spine-tipped lobes. Flowers purple, 6–10 mm long; calyx glabrous; sepals narrowly deltoid, spine-tipped, 3–5 mm long, shorter than the corolla. Legume often rupturing the calyx, 2–3 mm long with 1 or 2 seeds (Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
