Stems erect or decumbent, never rooting nodally, hispid, base not bulbous. Roots tuberous. Basal leaf blades ovate in outline, 3-5-foliolate, 3.8-10 × 2.7-9 cm, leaflets 1×-lobed, ultimate segments narrowly elliptic to oblanceolate, margins entire or with few teeth, apex broadly acute to rounded-obtuse. Flowers: receptacle hispid; sepals spreading or weakly reflexed ca. 1 mm above base, 7-10 × 3-5 mm, hispid; petals 10-22, yellow, 12-22 × 4-9 mm. Heads of achenes globose to cylindric, 8-14 × 8-10 mm; achenes 2.2-4.2 × 2.8-3.4 mm, glabrous, margin forming narrow rib 0.4-0.6 mm wide; beak usually persistent, filiform from deltate base, straight, 2-4 mm. 2n = 32.


Phenology: Flowering late winter–spring (Mar–May).
Habitat: Riverbanks and wet meadows
Elevation: 0-400 m
