Stems 10-40 cm, cespitose, not rhizomatous; roots tuberous. Leaves abaxially glabrous; leaflets irregularly 2-3-lobed, lobes often with 1-3 secondary lobes; apex rounded, glandular-apiculate. Inflorescences axillary, flowers solitary or loosely grouped in 2-3-flowered leafy cymes; peduncle not strongly clavate. Flowers: sepals (5-) 7-11.5 × 2.8-7 mm; stamens 20-40; filaments filiform to club-shaped, 2.2-6 mm. Follicles sessile, upright to widely divergent; body oblong, (7.7-) 8.5-11.5 mm, abruptly contracted into style beak; beak 0.8-1.7 mm. Seeds 1.5-2 mm, glabrous.
