Perennial, rhizomatous or stoloniferous herb to c. 10 cm high; stems slender, internodes much reduced so that leaves appear c. radical; taproot absent; bulb and bulbils absent. Indumentum of simple, eglandular hairs. Stipules conspicuous, to c. 5 mm long, rounded to truncate apex, membranous, glabrous, persistent. Leaves palmately trifoliolate, the rosettes in tufts at intervals; petiole 1–5 (–7) cm long, with sparse long spreading hairs; leaflets sessile, broadly obcordate, 2–12 mm long, 2–13 mm wide, bilobed (sinus to c. one-fifth (rarely one-third) leaflet length with callus in notch), green, glabrous above, sparsely appressed-pubescent below, margins ciliate, lobes oblong to obovate, apices rounded and 2–6 mm apart. Inflorescences axillary, 1-flowered; peduncles 1–6 (–11) cm long, usually longer than leaves (up to twice the length of the leaves), glabrous or sparsely hairy. Bracts situated in the upper one-quarter to one-fifth of the pedicel, linear-lanceolate, 1.5–4 mm long, glabrate, calli absent. Sepals elliptic, 3–5 mm long, glabrous or ciliate, calli absent. Petals 6–12 mm long, white, usually glabrous, sometimes ciliate. Stamens at 2 levels; filaments glabrous, not dilated at base. Ovary glabrous. Styles glabrous. Capsules ovoid to globose, 4–5 mm long, glabrous. Seeds 1.5 mm × c. 1 mm, ± flattened ellipsoid-ovoid, smooth to slightly longitudinally furrowed, brown, glossy.
Perennial, sometimes mat-forming. Stems to c. 15 cm long, thin, creeping, glabrous, rooting at nodes. Lvs 3-foliolate, the rosettes in tufts at intervals, glabrous or hairy. Petiole (0.5)-1.5-5-(9) cm long, often dark reddish; stipules 3-5 mm long, broad and scarious. Lamina of leaflets equal, subsessile or nearly so, 2.5-9 × 2.5-9 mm, broadly obcordate, often dark reddish or deep purple below; sinus broad or narrow, rather shallow. Fls solitary; peduncles slender, 1-6-(11) cm long, hairy. Bracts 2.5-4 mm long, linear-lanceolate, glabrate; calli 0. Sepals 3-5-(6) mm long, ± elliptic, with ± appressed hairs; calli 0. Petals 8-15-(20) mm long, broad-obovate, white, usually glabrous, sometimes ciliate. Stamens at 2 levels, glabrous; filaments not dilated at base. Styles slightly to obviously > longer stamens, glabrous. Capsule 4-5 mm diam., globose. Seed 5-7 mm long, ± ellipsoid-ovoid, with prominent raised reticulations.
A herb which keeps growing from year to year. It grows 5-10 cm high and spreads 20-50 cm wide. The rhizomes or underground stems, branch. The plant forms leafy tufts. The leaves have 3 leaflets. The leaflets are 0.4-1 cm long by 0.3-0.8 cm wide. They are green above and waxy underneath. The flowers are 0.8-2 cm across and white. They occur singly on slender stalks. The stalks are about 4 cm long. The fruit are capsules about 0.5 cm across.
