Radical leaves 4–30 × 1–4 cm including petiole; stipules brown, membranous, abaxially sparsely villous; leaf blade 3-foliolate; leaflets green on both surfaces, oblong, elliptic, ovate, broadly ovate, or rhombic-ovate, both surfaces appressed to spreading pilose, abaxially more densely so on veins, base cuneate or broadly so, margin acutely many serrate or obtusely crenate, apex obtuse or acute; cauline leaves 1 or 2; stipules green, herbaceous, sparsely villous, apex acutely incised serrate, entire, or very rarely 2-fid; leaflets resembling those of radical leaves but very shortly petiolulate and margin less serrate. Inflorescence terminal, laxly corymbose-cymose, many flowered. Flowers 0.8–1 cm in diam.; pedicel slender, 1–1.5 cm, pilose.
