Plants perennial, mat-forming. Taproots stout, woody. Stems ascending to erect, green, 4-15 cm, trailing stems to 30 cm, glabrous, internodes of flowering stems ca. as long as leaves. Leaves overlapping proximally, all evenly spaced, connate proxi-mally, with tight, scarious sheath 0.5-0.7 mm; blade arcuate, green, flat, 3-veined, needlelike to subulate, 3-6(-9) × 0.7-2 mm, ± rigid, margins scarious proximally, apex green, blunt to ± acute, dull, glabrous; axillary leaves present among vegetative leaves. Inflorescences 5-20-flowered, open cymes; bracts narrowly lanceolate, herbaceous, thinly scarious-margined. Pedicels 0.5-2.5 cm, sparsely stipitate-glandular. Flowers: hypanthium dish-shaped; sepals (1-or) 3-veined, narrowly lanceolate (herbaceous portion narrowly lanceolate), 5-6 mm, not enlarging in fruit, apex often purple, acute to acuminate, not hooded, sparsely stipitate-glandular; petals broadly linear to oblong-elliptic, 0.7-0.9 times as long as sepals, apex rounded, entire to slightly emarginate. Capsules ellipsoid, 4-4.8 mm, shorter than sepals. Seeds purplish brown, elliptic-oblong, ± compressed, 1.8-2.2 mm, tuberculate; tubercles low, rounded.
