Plants solitary or in tufts, not stoloniferous, weakly rhizomatous, with small caudex. Leaves basal and cauline, (basal usually ephemeral, gradually dying through growing season, cauline conspicuous, reduced distally); petiole flattened, (5–)10–60(–90) mm; blade round to reniform, 3–7(–9)-lobed usually less than halfway to midvein (distal unlobed), (3–)5–18(–20) mm, slightly fleshy, margins entire, eciliate or sometimes sparsely glandular-ciliate, apex rounded, sometimes acute, surfaces glabrous or sparsely stipitate-glandular. Inflorescences 2(–5)-flowered paniculate or racemelike thyrses, sometimes solitary flowers, (flowers nodding in bud), some or all flowers but terminal one on each branch often replaced by bulbils, 3–30 cm, stipitate-glandular; bracts (proximal ephemeral), petiolate or sessile. Flowers: sepals erect, (sometimes reddish), oblong, margins glandular-ciliate, surfaces short-stipitate-glandular; petals white, not spotted, obovate to spatulate, 5–12 mm, longer than sepals; ovary superior. 2n = 24, 36, 48, 52, 56, 60, 70, 72.
