Short-lived annual, stems ascending to erect, 2–40 cm long, variably pilose to almost glabrous. Leaves of juvenile plants broadly 3–5-lobed to palmatifid, adult leaves shallowly to deeply 3–5-lobed or palmatisect, the lobes or segments toothed or again divided, usually 0.5–2 cm long and wide overall; petioles mostly 1–3(–10) cm long. Flowers 2–3 mm diam., sessile or subsessile, rarely pedicels elongating to c. 0.5 cm long in fruit; sepals 3–4, oblong to elliptic, c. 2 mm long, pilose on back; petals 1 or 2, c. spathulate or oblong, slightly shorter than sepals, pale yellow-green; nectary attached at or slightly above middle, lobe minute, triangular to obovate, fused with petal along margins; stamens usually 3(–6). Achenes c. 10–20, ovate or orbicular, 1.5–2 mm long, flat to slightly biconvex, the faces with scattered tubercles, each terminated by a hooked bristle no longer than the diameter of the tubercle itself; beak acute, c. 0.3–0.5 mm long; receptacle glabrous. .
