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, 10–16 mm long, margins entire, pale brown, 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, rounded. Sheath-mucro penicellate, straight and erect, 2–4 mm long, Sheath with distinctive rounded apex. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose, 20–80 mm long, 10–20 mm wide. Male inflorescence spathes persistent, shorter than spikelets, chartaceous, Soon decaying in the apical half. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex rounded, 9–16 mm, 6–10 mm, with 10–25 flowers, pedicels absent ie spikelets sessile. Male bracts as tall as flowers or taller than flowers, 7–10 mm long, ovate, acuminate, margins entire, coriaceous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, bracts stiff, almost looking awned. Male flower 4.5–7 mm long. Male tepals sepals more rigid than petals, cartilaginous, petals cartilaginous, oblong or ovate, inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged, glabrous. Anthers 2.25–3 mm long, included in the flowers. Pistillode present. Females: female inflorescence globose or linear, 10–70 mm long, 15–25 mm wide, with 1 spikelet or 2–5 spikelets or 6–10 spikelets. Female spathes shorter than the spikelets, persistent, chartaceous. Female spathellae inconspicuous or absent. Female spikelet sessile, ovate or orbicular or undifferentiated, apex rounded or undifferentiated, 12–17 mm long, with 4–15 flowers, with 2–5 sterile bracts. Female bracts shorter than flowers or as tall as flowers or taller than flowers, reflexed, 10–12 mm long, ovate, acuminate or aciculate, coriaceous, apical margin like rest of bract, same as body of bract, margins entire, awn between half and as long as the bract body or longer than the bract body. Female flower 9–11 mm long, without a fleshy pedicel, six tepals. Female tepals coriaceous or cartilaginous, glabrous and smooth, midrib flush with the tepal body, margins entire, apices acute, inner whorl longer than outer. Female outer lateral tepals conduplicate, hidden by bracts, or bracts are shorter than flowers, 5.5–6 mm long. Female odd outer tepal oblong or ovate, 5.5–6 mm long. Female inner tepals oblong or ovate, 8–9 mm long. Staminodes present (red anther). Styles feathery, 3. Style bases free. Ovary with 3 locules, dehiscent (whole flower falls off inflorescence seed flattened 3 x 1mm). Fruit: seed (1.68–)2.03(–2.28) mm long, (1–)1.16(–1.52) mm in diameter, shape in side view oblong, shape in diameter elliptical in cross section, brown.
