Prostrate, mat-forming, perennial; stems condensed, corm-like, covered with fibrous remains of old leaf sheaths, producing creeping runners rooting at nodes, runners glabrous, 0.5-1.5(-2.0) mm diam., internodes 10-140 mm long. Roots few, thong-like. Leaves all basal, in distant tufts of 2-5 along runners, petiole (5-)10-100(-200) mm long with stipules adnate and sheathing for 2-10 mm, glabrous or thinly villous with hairs to 1 mm long, blade ovate to cordate or reniform, (2-)5-20(-25) mm diam., weakly or strongly 4-12(-16)-crenate or dentate (rarely ± entire), with reddish callus at the tip of each serration, leathery, glabrous but usually with scattered hairs on margins, or adpressed-pilose adaxially. Flowers solitary at nodes, (5-)8-14 mm diam.; peduncle naked, scapose, ± as long as leaves, (5-)10-60 mm long, 0.5-1.0 mm diam. Sepals 5, weakly to strongly reflexed, ovate to suborbicular, cucullate, (2-)3-4 mm long, glabrous, yellowish. Petals 5-10, linear-lanceolate or ligulate, (3-)4-7 x 1.0-1.5 mm, pale yellow, narrowed into short claw in basal ±1 mm, acute or attenuate, veins 3, unbranched, nectary pocket-like with acute flap. Stamens 11-30 in ±2 series, filaments 0.5-2.0 mm long, anthers ±0.5 mm long. Carpels 6-20(-30), glabrous. Achenes in subglobose head, broadly ellipsoid, ±2 x 1.5 mm, smooth, keeled, shortly beaked; receptacle glabrous.
