Radical leaves 3–5 cm including petiole; stipules brown, membranous, abaxially sparsely white tomentose or subglabrous; leaf blade pinnate with 4–6 pairs of leaflets; leaflets usually opposite, sessile, long elliptic or obovate-oblong, 0.5–1 cm × 3–8 mm, abaxially white tomentose, adaxially gray-white or green tomentose and pubescent, or sparsely pubescent only, base cuneate, broadly so, or subrounded, margin sharply incised serrate, apex rounded; cauline leaves resembling radical ones but leaflets fewer higher up stem, eventually 3-foliolate; stipules leaflike, adaxially green or dark green, herbaceous, abaxially white tomentose, margin incised serrate. Flower solitary, 4–8 mm in diam. Sepals long ovate, apex acuminate; epicalyx segments elliptic-lanceolate, slightly shorter than sepals, abaxially densely white tomentose, apex obtuse or acute. Petals yellow or pale orange, oblong-lanceolate, shorter than or equaling sepals, apex obtuse. Stamens 5, alternating with sepals; filaments short. Style lateral.
