A perennial (or also annual ?), procumbent, delicate, succulent herb. Stems several from a short woody base, up to 25 cm. long, subdichotomously branched, sometimes from below, 4-gonous, slender, somewhat rigid and brownish below, herbaceous and green above, usually puberulous or hispid everywhere (hairs acute, hyaline, spreading, denser and longer above), or sometimes glabrous towards the base, or rarely papillose-puberulous; internodes variable in length, often longer than the leaves. Leaves 0·3-3·5(4·5) cm. long (incl. subpetiolar base) and 0·25-1·3 cm. broad, elliptic, spathulate or obovate to subcircular, acute or nearly so to obtuse or rounded at the apex, entire, cuneate and narrowing into a subpetiolar base, or subsessile, rarely distinctly petiolate, flat, subfleshy when fresh, membranaceous on drying, dark green, sometimes with a purple pattern, usually puberulous or hispidulous on both faces, rarely glabrous, slightly connate at the base. Flowers 5-merous, axillary and solitary, only one at each node, and also in terminal, lax cymes, sometimes in fascicles-like cymes at the end of ± short axillary branchlets; pedicels filiform, hispidulous, elongating in fruit up to 30(35) mm. Calyx 1·5-2·5(2·75) mm. long, green, hispidulous; sepals linear or linear-lanceolate, obtuse, connate at the base for 0·3-0·6 mm. Corolla 2·25-3·5 mm. long, white or pale pink, petals ovate or oblong-obovate, somewhat contracted towards the obtuse apex, smooth, with the median nerve hispid outside. Filaments 1·25-2·25 mm. long. Follicles (with styles) 2·25-3 mm. long; styles 0·3-1 mm. long. Seeds muriculate.
