Vegetative parts: plants mat-Forming or tangled, 0.2–1 m tall, basal diameter 0.3–2 m, crown diameter 0.3–2 m, with stolons. Fertile culms branching or much branched, finely rugulose or rugose, green, 0.2–1 m tall, diameter at base 0.4–0.5 mm, diameter at apex 0.08–0.2 mm. Sheaths persistent, with no abscission line, closely convoluted, 5–7 mm long, pale brown, apical margins coriaceous, like the rest of the body, hyaline shoulders tall, acute, hyaline shoulder 0.5 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate or clavate, straight and erect, 0.5 mm long, massive shoulders, but these very soon decay. Males: male inflorescence with 1 spikelet or 2–5 spikelets, sparsely paniculate, 5–15 mm long, 3–5 mm wide. Male inflorescence spathes persistent, shorter than spikelets, coriaceous or membranous, like sheaths. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical, apex undifferentiated, 3–4 mm, 0.8–1 mm, with 1 flowers, pedicels absent ie spikelets sessile. Male bracts shorter than flowers, 1.5–3 mm long, oblong, acute, chartaceous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, upper half decaying, thus usually not visible. Male flower 2.5–3 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, linear or oblong, inner tepals shorter than outer tepals. Male outer lateral tepals conduplicate, glabrous. Anthers 1.8 mm long, exserted from the flowers. Pistillode absent. Females: female inflorescence sparsely paniculate, 3–15 mm long, 2–5 mm wide, with 1 spikelet (usually) or 2–5 spikelets (rarely two). Female spathes shorter than the spikelets, persistent, coriaceous or membranous. Female spikelet sessile, elliptical, apex undifferentiated, 3–4.5 mm long, with 1 flowers, with 0 sterile bracts. Female bracts shorter than flowers, 3–4 mm long, oblong, acute, chartaceous, apical margin membranous, paler than body of bract, awn minute or absent or less than half as long as the bract body. Female flower 2.4–4 mm long, without a fleshy pedicel. Female tepals cartilaginous, glabrous and smooth, midrib flush with the tepal body, apices acute, inner whorl shorter than outer. Female outer lateral tepals like other tepals, 2.4–4 mm long. Female odd outer tepal linear or oblong, 2.4–3.4 mm long. Female inner tepals linear or oblong, 2–3 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent. Fruit: seed 0.9 mm long, 0.7 mm in diameter, shape in side view oblong, shape in diameter round in cross section, white, colliculate or brittle, white ornamentation.
