Annual or perennial prostrate or straggling plant, with sparsely to densely hairy stems 10–30(–50) cm. long, sometimes rooting at the nodes and occasionally forming mats or cushions. Leaf-blades ovate to elliptic-ovate, 0.35–1.7 cm. long, 0.2–1.2 cm. wide, acute to rounded at the apex, cuneate to rounded at the base, always conspicuously ciliate at the margins, the surface either glabrous or the midvein slightly hairy above and the lower surface sparsely hairy; petiole 0.5–2 mm. long, glabrous to hairy; stipule-sheath ± 0.5–1 mm. long, produced into a 2-fid lobe 1.5–2 mm. long, ciliate. Inflorescences terminal or on very short axillary shoots, sessile, mostly (3–)7–15-flowered, rather laxly subglobose, up to ± 1.3 cm. wide; pedicels 1–5 mm. long, glabrous or densely pilose. Flowers heterostylous, 4-merous. Calyx-tube subglobose, 1 mm. long, glabrous or densely spreading pilose; lobes narrowly oblong-triangular to lanceolate, 1.2–2 mm. long, 0.4–0.9 mm. wide, glabrous or with margins and midvein ciliate. Corolla white, pale mauve or pink; tube 0.3–0.6 mm. long; lobes oblong-lanceolate, (0.8–)1.4–1.8 mm. long, 0.5–0.7 mm. wide, glabrous or sparsely hairy on the midnerve outside. Style in short-styled flowers 0.3–0.4 mm. long, in long-styled flowers 1.8–2 mm. long. Capsule campanulate, 1–1.5 mm. long, 1.7–2 mm. wide, glabrous to densely spreading hairy, crowned by the persistent calyx-lobes; beak slightly raised, ± 0.5 mm. tall. Seeds black, ovoid, distinctly angular, ± 0.3 mm. long. Fig. 40/3, p. 270.
