Glab. far-creeping branching herb forming patches up to c. 1 m. diam. Stems up to ± 5 mm. diam., somewhat succulent, with acrid yellowish sap. Strongly insolated plants quite prostrate with rather close-set branches and subsessile lvs; plants of shady places and damp ground of laxer growth, with rather distant, distinctly petioled, thinner lvs and ascending to spreading elongate branchlets. Lvs on petioles ± 1-5 mm. long. Lamina pale green, somewhat fleshy to membr., obovate-oblong, rather abruptly narrowed to base, sinuate to obscurely, bluntly dentate (rarely rather coarsely toothed), 10-15 × 7-15 mm., 15-30 × 10-20 mm. Fls solitary on slender peduncles 1-2 cm. long. Calyx 1-2-5 mm. long; lobes narrow-oblong to narrow-triangular, acute. Corolla white, deeply lobed; lower lip spreading, upper ascending; lobes ± 10 mm. long. Berry somewhat compressed, obliquely subovoid to subglobose, ± 7-10 × 7 mm., purplish red.

Glabrous, prostrate or semi-prostrate herb often forming large mats to c. 1 m diam., compact when in exposed situations. Stems creeping, rooting at nodes, rather stout, somewhat succulent, usually branched. Petioles 1-5 mm long. Lamina (4)-7-25-(35) × (4)-7-20-(25) mm, obovate-oblong to orbicular, sinuate to bluntly and obscurely dentate or sometimes rather coarsely toothed, membranous to somewhat succulent. Peduncles 1-2 cm long, slender. Fls solitary. Calyx lobes 2-3 mm long, narrow-oblong to narrow-triangular. Corolla white, deeply lobed; lobes c. 10 mm long, ± narrow-elliptic, acute; lower lip spreading; upper lip ascending. Fr. ± 6-10 × 5-8 mm, obliquely subovoid to subglobose, reddish purple to pinkish purple, somewhat compressed.
