Herbs glabrous or pubescent with at least a few recurved, falcate hairs, glabrous or glandular puberulent distally; stolons with apical tuber. Stems 3–50 cm. Leaves: petiole 0.3–5 cm; blade usually ovate to broadly ovate, rarely suborbiculate, 1.5–7.5(–11) × 1.5–5.5(–8) cm. Inflorescences 0.7–12(–17) cm. Flowers opening before elongation of axis, corymbiform; pedicels erect or ascending at anthesis, 0.7–3.5 mm, with or without a minute, setaceous bracteole at base; floral tube a mere constriction to 0.6 mm, funnelform to very broadly so, nectary wholly within floral tube; sepals white or pink, sometimes purple tinged apically, oblong or ovate to broadly ovate, 0.8–1.8(–2.2) × 0.6–1.3 mm; petals white, obtriangular or obdeltate to obovate or broadly obovate, 0.6–2 × 0.6–1.8 mm; apical notch to 1/2 length of petal; filaments 0.7–2.2 mm; style 0.6–2.3 mm. Capsules clavoid, tapering smoothly to pedicel, without ribs or grooves, 1.6–2.6 × 0.5–1.2 mm, 1-locular, 1-seeded; pedicel and mature fruit combined length 3.5–7.8 mm.
