Prostrate or scrambling perennial; stems to 2 m long, hispid, with short to long, recurved to spreading hairs, rarely glabrescent; taproot thickened. Leaves reniform (to c. triangular on upper stems), 1–4 cm long, palmatifid into 3–5(–7) broad, 2- or 3-sected, sometimes toothed, primary lobes; ultimate lobes acute, or obtuse and minutely mucronate; upper surface with scattered curved hairs; stipules ovate to triangular, acuminate, often laciniate. Flowers solitary or paired; peduncles 0.5–2.7 cm long, pedicels 0.5–1.6 cm long.

Fruits 11–16 mm long; mericarps sparsely pubescent with short recurved to divergent hairs becoming longer toward awn, and scattered long hairs; suture margins not ciliate but sometimes with occasional short hairs; seed rugose with oblong and isodiametric alveolae and occasional membranous deposits.
