Radical leaves 5–10 cm including petiole; stipules yellow-brown, membranous, abaxially strigose and pubescent; leaf blade pinnate with 3 or 4 pairs of leaflets; leaflets opposite or alternate, at intervals of 1–1.5 cm, adaxially yellowish or grayish green, oblong, obovate-oblong, or obovate-lanceolate, 2–5 × 0.5–1.5 cm, adaxially densely strigose and pubescent, densely villous along midvein and lateral veins, base cuneate or broadly so, margin pectinate, apex obtuse; lobes fasciated oblong or oblong-lanceolate; cauline leaves resembling radical ones but petiole shorter and leaflets fewer higher up stem; stipules yellowish green, herbaceous, margin dentate-parted. Inflorescence corymbose-cymose, compact, many flowered. Flowers ca. 1 cm in diam.; pedicel 0.8–1.5 cm, strigose and pubescent. Sepals triangular-ovate, apex acute; epicalyx segments elliptic-lanceolate, nearly equaling sepals, markedly dilated in fruit, abaxially densely strigose and pubescent, apex acute. Petals yellow, obovate, slightly longer than sepals, apex rounded or emarginate. Style subterminal, base thickened. Achenes ellipsoid-reniform, markedly rugose. Fl. and fr. Jun–Aug.
