Leaves with petioles 1.5–16 cm long; lamina trifoliolate or deeply palmatisect, ± orbicular in outline, 1–7 cm diam., matt, leathery; leaflets narrowly elliptic (rarely linear) to obovate-cuneate, usually deeply lobed, ultimate segments mostly 1–3 mm wide, acutely toothed, glabrous or with few scattered hairs. Flowering stems erect, to c. 30 cm long, 1–3-flowered, usually appressed-hirsute. Sepals 5, spreading, ovate, 4–8 mm long, appressed-hairy below. Petals 5–15, oblanceolate to obovate, 5–11 mm long, golden-yellow; nectary near petal-base, pocket-like, ± 0.5 – 1 mm long, with apex of lobe shallowly emarginate or sinuate, often asymmetric, and margins excurrent. Stamens 12–50. Pistils 9–15. Receptacle glabrous. Achenes inflated, subglobular or broadly obovate, 2.7–4 mm long; lateral faces with 3–4 broad, oblique ridges; beak erect or reflexed, c. 1.5 mm long.
