Characteristics

Glabrous, perennial herb; stems prostrate, creeping, sprawling or decumbent, rooting at nodes. Lvs shortly petiolate, sometimes with petioles to 2 cm long, mostly on distal ascending part of stems, not decussate or imbricate except in small rosettes at stem apices, to 45-(55) × 40-(43) mm, broadly ovate, broadly oblong-elliptic, to suborbicular or almost square, flat, entire, green or glaucescent, often suffused with red, especially towards margins, dotted with numerous whitish or reddish hydathodes; base rounded, truncate or subcordate; apex rounded or ± emarginate. Infl. a loose thyrse, to c. 10 cm long but very variable in size; main axis with very small bracts. Fls 5-merous, 8-12 mm diam., usually 12-numerous, on pedicels slightly < to = fls. Calyx 1.5-2 mm long; lobes triangular. Corolla star-like; petals free and patent, (4)-5-6 × 1-2 mm, narrowly triangular or triangular-lanceolate, rose to crimson in bud, pale pink inside at anthesis; apex acute. Stamens 3-4 mm long, < carpels. Scales 0.2-0.3 mm long, ± rectangular (wider than long). Frs and seeds not seen, but fls often replaced by small plantlets in infl. branch axils.

Perennials with decumbent to almost erect branches rarely longer than 0.4 m, sparsely branched, with old leaves not deciduous. Leaves with petioles 5-20 mm long; lamina broadly elliptic to oblong-obovate, 20-50(-65) x 15-40 mm, obtuse or emarginate, more or less abruptly constricted into petiole, dorsiventrally flattened, with slightly recurved margin, entire, green often yellowish green. Inflorescence a rounded or elongate thyrse with few to many dichasia, with 4-or 5-merous flowers, with peduncle 30-80(-100) mm long. Calyx: lobes triangular, 1-2 mm long, acute and ridged, glabrous, green sometimes tinged red. Corolla star-shaped, fused at base for about 0.5 mm, cream or white and usually tinged red towards apices. Stamens with purple anthers. Squamae transversely oblong, 0.2-0.3 x 0.4-0.6 mm, truncate, not constricted downwards, fleshy, white or cream.
