Vegetative parts: plants tangled, 0.3–0.5 m tall, basal diameter 1–3 m, crown diameter 1–3 m, with stolons. Fertile culms branching, finely warty (papillae often white), olivaceous, 0.3–0.5 m tall, diameter at base 0.6–1.5 mm, diameter at apex 0.2–0.3 mm. Sheaths closely convoluted, 4–10 mm long, dark brown, densely papillate, apical margins narrowly membranous, 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, 1–3 mm long, distinctive with papillate surface, and large membranous lobes usually overtopping the clavate mucro. Males: male inflorescence with 6–10 spikelets or 11–20 spikelets or 21–50 spikelets, paniculate, 20–40 mm long, 4–10 mm wide. Male inflorescence spathes persistent, taller than spikelets, coriaceous, enfolding the spikelets. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical, apex acute, 3.5–5 mm, 0.8–1 mm, with 1 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts shorter than flowers, 2–2.5 mm long, oblong, acute, chartaceous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, quite an insignificant structure, with the spikelet dominated by the spathe. Male flower 3–4 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals membranous, linear or oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, glabrous. Anthers 1.3–1.8 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence paniculate, 15–35 mm long, 5–10 mm wide, with 2–5 spikelets or 6–10 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent, coriaceous. Female spikelet sessile or pedicel simple, elliptical, apex acute, 4–5 mm long, with 1 flowers, with 1–3 sterile bracts. Female bracts shorter than flowers, 3–3.5 mm long, oblong, acute, chartaceous, apical margin like rest of bract, paler than body of bract, awn minute or absent. Female flower 4–5 mm long, without a fleshy pedicel. Female tepals cartilaginous (sepals) or membranous (petals), glabrous and smooth, midrib flush with the tepal body, apices acute, inner whorl shorter than outer. Female outer lateral tepals like other tepals or conduplicate, 4–5 mm long. Female odd outer tepal linear or oblong, 3–4 mm long. Female inner tepals linear or oblong, 3–3.5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent. Fruit: seed 1.4 mm long, 0.84 mm in diameter, shape in side view elliptical, shape in diameter round in cross section or triangular in cross section (round with two small lateral indentations), tan, smooth (shiny).
