Vegetative parts: plants tufted, 0.4–1.2 m tall, basal diameter 0.2–0.3 m, crown diameter 0.3–0.5 m, compact, without spreading rhizomes or stolons. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth or finely rugulose, olivaceous, 0.4–1.2 m tall, diameter at base 1–2 mm, diameter at apex 0.8–1.5 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths more than 1 per culm, dropping off, with an abscission line present, loosely convoluted or flat and standing free from culm, 10–25 mm long, margins entire, golden, upper 1/3 in colour and texture similar to the lower 2/3, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 1–3 mm long, Sheaths frequently still present on culms. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets or 11–20 spikelets, racemose or paniculate, 25–130 mm long, 10–20 mm wide. Male inflorescence spathes persistent, taller than spikelets, chartaceous, 15–35mm long and golden brown. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded or undifferentiated, 8–15 mm, 5–7 mm, with 15–25 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts more than twice as tall as flowers, 9–12 mm long, linear or ovate, acuminate, margins entire, hyaline or chartaceous or cartilaginous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent. Male flower 3–4 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong or ovate, inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged, glabrous. Anthers 1.25–2 mm long, included in the flowers. Pistillode present. Females: female inflorescence linear, 15–90 mm long, 10–20 mm wide, with 6–10 spikelets or 11–20 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent, chartaceous. Female spathellae inconspicuous or absent. Female spikelet sessile or pedicel simple, oblong or ovate, apex rounded, 8–20 mm long, with 8–20 flowers, with 0–3 sterile bracts. Female bracts taller than flowers or at least twice as long as flowers, erect, 10–14 mm long, linear or ovate, acuminate, hyaline or chartaceous or membranous, apical margin membranous, paler than body of bract, margins entire, awn minute or absent. Female flower 4–5.5 mm long, without a fleshy pedicel (dark brown in colour and tepals curve inwards), six tepals. Female tepals coriaceous or cartilaginous, glabrous and smooth, midrib flush with the tepal body, margins entire, apices acuminate, inner whorl longer than outer. Female outer lateral tepals conduplicate, hidden by bracts, or bracts are shorter than flowers, 2.5–4 mm long. Female odd outer tepal oblong or elliptical, 2.5–3.5 mm long. Female inner tepals oblong, 3–5.5 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 3 locules, dehiscent. Fruit: seed (1.16–)1.29(–1.48) mm long, (0.64–)0.74(–0.84) mm in diameter, shape in side view elliptical, shape in diameter round in cross section, brown; funicular elaiosome absent.
