Herbs perennial. Roots robust, terete, usually woody. Flowering stems erect or ascending, together with petioles pubescent, sparsely villous, and sessile glandular. Radical leaves 4–12 cm including petiole; stipules brown, membranous, abaxially densely sessile glandular, pubescent, and pilose; leaf blade 3-foliolate or pedately (rarely subpinnately) 5-foliolate; central 3 leaflets shortly petiolulate, the lateral two (if present) sessile, all leaflets obovate-cuneate or obovate, both surfaces densely spreading pubescent and sessile glandular, abaxially more densely so on veins, base cuneate, margin markedly revolute, obtusely serrate proximally, apex truncate or obtuse; cauline leaves: stipules ovate-elliptic, herbaceous, margin entire, apex obtuse or 2-or 3-serrate; petiole gradually shorter higher up stem; leaf blade 3-or 5-foliolate; leaflets resembling those of radical leaves. Inflorescence corymbose-cymose, laxly few flowered. Flowers 1.2–1.5 cm in diam.; pedicel slender, 2–2.5 cm, densely pubescent and sessile glandular. Sepals triangular-lanceolate, apex acuminate; epicalyx segments lanceolate or elliptic-lanceolate, slightly shorter than sepals, apex acute. Petals yellow, obovate, ca. 1/2 as long as sepals, apex rounded. Style markedly thickened at base; stigma dilated. Achenes slightly rugose. Fl. and fr. Jul–Aug.
