Plants perennial, mat-forming. Taproots filiform to slightly thickened. Stems ascending to erect, green, 3-10 cm, glabrous, internodes of all stems 2-4 times as long as leaves. Leaves overlapping prox-imally (basal rosette), perfoliate, connate proximally, with ± tight, herbaceous to scarious sheath 0.5-1 mm; blade erect to spreading, green, weakly 1-veined abaxially, flat, ± linear, 4-12(-15) × 0.5 mm, flexuous, margins not thickened, slightly scarious to herbaceous, smooth, apex green, rounded, dull, glabrous; axillary leaves absent. Inflorescences 3-5-flowered, open, leafy cymes or sometimes solitary, terminal; bracts linear to subulate, mostly herbaceous. Pedicels 0.2-1(-2) cm, glabrous. Flowers: hypanthium disc-shaped; sepals obscurely veined, elliptical-oblong to obovate (herbaceous portion elliptical-oblong to obovate), 2-4.5 mm, not enlarging in fruit, apex green, obtuse to rounded, not hooded, glabrous; petals clawed, broadly obovate, 2-2.2 times as long as sepals, apex rounded, shallowly notched. Capsules on stipe shorter than 0.1 mm, broadly ellipsoid, 5.5 mm, longer than sepals. Seeds brown, obliquely triangular with adaxial groove, radicle prolonged into short beak, compressed, 0.5-0.8 mm, obscurely tuberculate. 2n = 20.
