Stoloniferous perennial. Leaves with petioles 1.5–15 cm long, with appressed or spreading hairs; lamina trifoliolate, 5–40 (–65) mm long and wide; segments cuneate to broadly oblanceolate, usually 3-toothed with slightly thickened apices, sometimes more deeply cleft and more abundantly toothed, dark-green, ± shining above, paler beneath, both surfaces glabrous to moderately appressed-hairy. Flowering stems usually shortly exceeding leaves, 1 (or 2)-flowered, erect (recurving in fruit), spreading-to appressed-hirsute. Sepals broadly elliptic to obovate, ± 3 mm long, spreading, (sometimes very sparsely) pilose below. Petals 5–11, oblong to obovate, 5–10 mm long, golden-yellow; nectary near petal-base, shallowly pocket-like, 0.2–0.5 mm long, with lobe-apex shallowly emarginate or slightly rounded. Stamens 25–40. Pistils 8–20. Receptacle (sub)glabrous in stamen zone, hispid above, or glabrous throughout. Achenes broadly ellipsoid, 2–2.5 mm long; lateral faces with 2–4 coarse oblique ridges or boldly reticulate; beak recurved, 0.5–1 mm long.
Grows in bogs, wet grasslands, soaks and seepage areas above c. 500 m, sometimes mat-forming.
