Radical leaves 7–12 cm including petiole; stipules brown, membranous, abaxially glabrescent; petiole sparsely pilose, appressed sericeous, or glabrescent; leaf blade pedately 5-foliolate, or 3-foliolate; leaflets shortly petiolulate or subsessile, obovate to obovate-oblong, abaxially pilose or appressed sericeous, rarely glabrescent, adaxially subglabrous, base cuneate, margin acutely or obtusely serrate or lobed to parted, sometimes entire, apex obtuse; stolon leaves resembling radical ones; stipules green, ovate-oblong or ovate-lanceolate, herbaceous, margin entire, rarely 1- or 2-serrate, apex acute or acuminate. Flowers solitary, axillary or opposite leaves, 1.5–2.2 cm in diam.; pedicel 6–9 mm, pilose. Sepals ovate-lanceolate, apex acute; epicalyx segments oblong-elliptic or elliptic-lanceolate, nearly equaling sepals, markedly enlarged in fruit, abaxially pilose, apex obtuse or acute.
