Vegetative parts: plants tangled, 0.3–0.6 m tall, basal diameter 0.1 m, crown diameter 0.3–0.5 m, compact, without spreading rhizomes or stolons. Fertile culms branching, round (not compressed), finely warty or roughly warty, green, 0.3–0.6 m tall, diameter at base 0.5–2 mm, diameter at apex 0.4–2 mm. Sheaths persistent, with no abscission line, closely convoluted, 5–30 mm long, reddish with white speckling, apical margins coriaceous, like the rest of the body, hyaline shoulders tall, acute (equalling the mucro), hyaline shoulder 0.5 of sheath body length, apex, excluding the membranous lobes, truncate. Sheath-mucro penicellate or clavate, straight and erect or recurved, 5–8 mm long, Truncate, tuberculate, reddish-brown sheaths, with a stout mucro equalling the acute membranous lobes is pretty distinctive for this group of species. Males: male inflorescence with 2–5 spikelets, racemose, 15–80 mm long, 10–25 mm wide. Male inflorescence spathes persistent, taller than spikelets, chartaceous, reddish-brown with a golden speckling. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, square, apex undifferentiated, 15–20 mm, 5–10 mm, with 6–12 flowers, pedicels absent ie spikelets sessile. Male bracts more than twice as tall as flowers, 8–13 mm long, linear or oblong, acute, chartaceous, bract upper margin like body of bract, bract awn minute or absent, Bracts all reaching the same height, thus basal bracts much longer than apical bracts. Male flower 3.6–4 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, keel sparsely villous. Anthers 1.5–2 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence 30–80 mm long, 15–25 mm wide, with 2–5 spikelets. Female spathes longer than the spikelets, not obscuring spikelet or obscuring spikelet, persistent, cartilaginous. Female spikelet sessile, oblong, apex truncate or rounded or obtuse, 12–25 mm long, with 2–10 flowers, with 0–2 sterile bracts. Female bracts at least twice as long as flowers, 8–16 mm long, linear or oblong, acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 3.5–4.5 mm long, without a fleshy pedicel. Female tepals cartilaginous, keels of lateral sepals sparsely villous, midrib flush with the tepal body, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 3.5–4.5 mm long. Female odd outer tepal linear or oblong, 3.5–4.5 mm long. Female inner tepals linear or oblong, 3.5–4 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 2 locules or 1 locule, dehiscent. Fruit: seed (1.28–)1.42(–1.6) mm long, 0.8–1 mm in diameter, shape in side view elliptical, shape in diameter plano-convex in cross section, tan or pink, smooth (shiny).
