Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth, olivaceous, 0.35–1 m tall, diameter at base 1.1–2 mm, diameter at apex 0.5–1.3 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, 10–12 mm long, margins entire, golden with brown speckled striations, 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, obtuse or rounded. Sheath-mucro penicellate, straight and erect, 2.5–5 mm long, Sheaths characteristically short and blunt. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, paniculate or globose, 25–60 mm long, 15–25 mm wide. Male inflorescence spathes persistent (fall off in old inflorescences), taller than spikelets, cartilaginous. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex obtuse, 10–15 mm, 6–10 mm, with 25–35 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 8–14 mm long, ovate, acuminate, margins entire, chartaceous or cartilaginous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, bracts quite broad at base, and brittle, extended into a long hyaline awn. Male flower 3–5 mm long. Male tepals sepals and petals the same rigidity, chartaceous, oblong, inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged, glabrous. Anthers 1.5–4 mm long, included in the flowers. Pistillode present (with 2 styles). Females: female inflorescence interrupted or globose or linear, 15–40 mm long, 12–25 mm wide, with 1 spikelet or 2–5 spikelets or 6–10 spikelets. Female spathes shorter than the spikelets or as long as the spikelets, persistent, cartilaginous. Female spathellae inconspicuous or absent. Female spikelet sessile, oblong or elliptical or ovate or undifferentiated, apex rounded or obtuse or undifferentiated, 10–25 mm long, with 20–40 flowers, with 0 sterile bracts. Female bracts taller than flowers, erect or reflexed, 10–15 mm long, ovate, acuminate, chartaceous or membranous, apical margin membranous, paler than body of bract, margins entire, awn minute or absent. Female flower 7–9 mm long, without a fleshy pedicel, six tepals. Female tepals cartilaginous, glabrous and smooth, midrib flush with the tepal body, margins entire, apices acute or acuminate, inner whorl longer than outer. Female outer lateral tepals conduplicate or keeled or winged, wings entire, narrower than body, hidden by bracts, or bracts are shorter than flowers, 3.5–6.5 mm long. Female odd outer tepal oblong or ovate, 4–6.5 mm long. Female inner tepals oblong, 4–9 mm long. Staminodes present. Styles feathery, 3 or 2. Style bases free. Ovary with 3 locules or 2 locules, dehiscent (seed 1.5–2mm long x 0.7–1.0mm wide). Fruit: seed (1.6–)1.72(–2) mm long, (0.72–)0.79(–0.92) mm in diameter, shape in side view elliptical, shape in diameter round in cross section, brown.
