Prostrate, perennial, creeping herb rooting at the nodes; stems slightly succulent, 10–45 cm. long, pubescent with short adpressed hairs. Leaf-blades elliptic to ovate-elliptic, 1.7–8.5(–9) cm. long, 0.7–4.7 cm. wide, obtuse or ± acute at the apex, narrowly cuneate at the base, sparsely to rather densely pubescent with short hairs above and beneath, particularly on the nerves; petiole (0.2–)1–2.5(–5) cm. long; stipules ± 3 mm. long, basal 1 mm. connate to the petioles, the apical 3–5 lobes 0.5–1 mm. long. Inflorescences 6–10-flowered, pubescent; peduncles up to 4.5 cm. long; pedicels obsolete or ± 1 mm. long; at some nodes, apart from the long-peduncled several-flowered inflorescence there is present in the opposite axil an additional 1–2-flowered inflorescence subsessile or on a much shorter peduncle (appearing as a long pedicel in single-flowered inflorescences). Calyx-tube 3–4 mm. long, pubescent; lobes 1.5–3 mm. long, 0.4–0.8 mm. wide. Corolla white; tube 5.5–8 mm. long, 1–1.5 mm. wide at the base, 3–5 mm. wide at the throat; lobes 2.5–4.5 mm. long, 1.5–2 mm. wide at the base; both tube and lobes shortly pubescent outside. Filaments ± 1 mm. long in long-styled flowers, the anthers immersed in a part of the corolla-tube bearing dense long hairs; in short-styled flowers the filaments are ± 3.5 mm. long but the tube is not densely hairy inside; anthers ± 2 mm. long in both. Style 5–6 mm. long and pubescent, with stigma-lobes 1.5 mm. long in long-styled flowers; in short-styled flowers the style is 1.5 mm. long and the stigma-lobes 2 mm. long. Fruits 6–7 mm. long, 1.5 mm. wide, pubescent, ± 30-seeded. Seeds brown particularly on the angles, very angular, polygonal, often resembling slices through a prism, the 2 large faces triangular, the 3 narrow ones oblong, reticulate, longest dimension ± 0.7 mm.
