Plants perennial, delicate, forming small to large tangled mats or straggling through grass, from slender rhizomes. Stems diffusely branched, 4-angled, 3-30 cm, gla-brous. Leaves sessile or subsessile; blade with midrib obscure, broadly elliptic-lanceolate to linear-lanceolate, widest at or above middle, 0.2-0.8(-1.5) cm × to 2 mm, ± succulent, base cuneate, margins entire, apex acute to acuminate, glabrous; leaf blades in terminal buds sometimes become fleshy and form gemmae. Inflorescences with flowers usually solitary, terminal and in axils of distal leaves forming open, diffuse cymes; bracts foliaceous, 1-10 mm; 1 or 2 pairs of bracteoles sometimes present, 1-3 mm, herbaceous or with narrow membranous margins. Pedicels erect or sharply angled at base, becoming sharply curved at apex, 3-40 mm, glabrous. Flowers 5-8 mm; sepals 5, 3-veined, narrowly triangular-lanceolate, 3-3.5(-4) mm, margins straight, narrow, scarious, apex acute, glabrous or rarely margins pubescent; petals 5, 2.5-5 mm, equaling to slightly longer than sepals; stamens 5 or 10; styles 3, ascending, curved at tip, ca. 2 mm. Capsules straw colored, conic to ellipsoid, 4-5 mm, longer than sepals, apex obtuse, opening by 6 valves; carpophore absent. Seeds reddish brown, reniform to round, 0.7-1 mm diam., rugose. 2n = 26.
