Plants perennial, matted, moss-like. Taproots filiform. Stems 15–25, decumbent, trailing, green, 1–4 cm; internodes angular to grooved, 1–11/2 times as long as leaves, minute, shiny, pubescence of widely spreading to slightly retrorse hairs in 2 lines. Leaves connate basally, with herbaceous sheath 0.1–0.2 mm, sessile; blade 1-veined, vein prominent abaxially, linear, 4–6 × 1 mm, herbaceous, rigid, margins thickened, herbaceous, shiny, lined with peglike cilia, apex acute, pungent-tipped, not pustulate, glabrous; axillary leaf clusters present. Inflorescences solitary flowers in distal leaf axils. Pedicels erect or ascending in fruit, 6–10 mm, minutely pubescent. Flowers: sepals green, 1-veined, slightly keeled proximally, broadly lanceolate (herbaceous portion narrowly lanceolate), 3–4 mm, not enlarging in fruit, apex acute to acuminate, not pustulate, glabrous; petals absent; stamens ca. 8. Capsules very loosely enclosed by calyx, ovoid, 2–3 mm, 2/3–4/5 times as long as sepals. Seeds 5–7, dark brown to black, subglobose, slightly compressed, ca. 1 mm, shiny, smooth.
