Rosette herbs with long, prostrate, partly sym-podial stems (stolons) bearing leaves and flowers and also reduced leaves, daughter plants produced on the nodes bearing reduced leaves. Stems, pedicels and petioles with long, ± patent hairs and usually many multicellular glandular hairs. Leaves trifoliolate, petiole up to 12(-16) cm. Stipules membranous, c. 1 cm long, long-hairy outside. Leaflets sessile or shortly petioluled, apical leaflets rhomboid to obovate, 1.5-3.5 by 1-2.5 cm, base cu-neate, apex rounded, serrate in upper part, lateral leaflets elliptic to ovate, slighdy smaller and usually with unequal base, all leaflets long hairy below and on the nerves also with glandular hairs. Flowers solitary, seemingly placed opposite the runner-leaves, rarely 6-merous, pedicels 2-8 cm long. Hypanthium 2-3.5 mm diam., sparsely hairy outside* Epicalyx leaves ± obovate, 3-5 by 2-3 mm during anthesis, distinctiy growing afterwards, with 2-6 incisions in the apical part, sparsely hairy outside. Sepals narrowly triangular, 4-6 by 2-3 mm during anthesis, indumentum outside as epicalyx. Petals obovate, 3.5-4.5 by 2-3.5 mm, yellow. Stamens 15-20, filaments up to 2.5 mm, anthers c. 0.5 mm. Torus elevated, hairy or glabrous, distincdy enlarging after anthesis. Pistils many, sessile, ovary glabrous, style inserted laterally above the middle and in anthesis much longer than the ovary.
