Perennial herb with napiform or cylindric taproot to c. 2.5 cm diam.; caulorrhiza short and thick, bearing long weakly ascending flowering stems. Hairs variable; longer hairs straight to slightly curved; glandular hairs short and inconspicuous. Basal lvs: petiole to 30 cm long, with fine, straight or curved long hairs and shorter straight and crisped retrorse hairs; lamina to c. 7 cm diam., reniform to orbicular, lobed to 3/4-⅞ way to midrib, glabrous or densely hairy above; lobes (5)–7, obovate; larger lobes with (3)–5–(9) teeth; median and larger lateral teeth ± oblong, usually obtuse. Cauline lvs similar to basal but smaller, usually 3–5-lobed; teeth usually 3–5 per lobe. Peduncle and pedicels with hairs as on petioles; bracteoles lanceolate or narrow-triangular; fls usually in pairs, occasionally solitary. Sepals ovate or elliptic-ovate; outer sepals c. 5.5 × 3.5 mm excluding mucro; inner sepals slightly narrower; hairs straight or slightly curved, antrorse and ascending. Petals to c. 7.5 × 4.5 mm, obovate, rose-pink. Mericarp hairy; beak to c. 15 mm long. Seed c. 2 × 1.6 mm diam., subglobular to oblong, dark reddish brown or almost black; dorsal alveolae deep, usually 4–6-sided, isodiametric or longer than wide.
