Vegetative parts: plants tufted, 1–2 m tall, basal diameter 0.1–0.2 m, crown diameter 0.5–1 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, 1–2 m tall, diameter at base 1–2 mm, diameter at apex 0.8–1.8 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, 12–27 mm long, margins entire, golden 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, acute. Sheath-mucro absent or penicellate, straight and erect, 0.5–1.5 mm long, sheaths lanceoclate, dropped at anthesis or earlier. Males: male inflorescence with 11–20 spikelets, paniculate (identical to female inflorescence), 50–140 mm long, 15–25 mm wide. Male inflorescence spathes persistent, taller than spikelets, chartaceous or membranous (1 large spathe subtends 2–4 spikelets), Very prominent and golden-brown, and quite membranous. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex obtuse or acute, 9–20 mm, 5–10 mm, with 15–20 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts more than twice as tall as flowers, 8–12 mm long, linear or ovate, acuminate, margins entire, hyaline or chartaceous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, Pale brown at base, where wider, soon tapering to a long hyaline apex. Male flower 3.5–4.5 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong (tapering apex), inner tepals longer than outer tepals. Male outer lateral tepals keeled or winged, glabrous. Anthers 1.5–2 mm long, included in the flowers. Pistillode present. Females: female inflorescence linear, 30–50 mm long, 10–25 mm wide, with 11–20 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent, chartaceous (become lacerated and thickened part of back starts to peel away). Female spathellae inconspicuous or absent. Female spikelet sessile or pedicel simple (spikelets arranged in pairs, subtended by 1 large,obvious spathe and 1 smaller one), oblong, apex obtuse or acute, 10–15 mm long, with 16–20 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, erect, 9–13 mm long, linear or ovate, acuminate, chartaceous, apical margin membranous, paler than body of bract, margins entire, awn minute or absent. Female flower 3.5–4.5 mm long, without a fleshy pedicel, six tepals. Female tepals 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, 2.5–3 mm long. Female odd outer tepal ovate, 2.5–3 mm long. Female inner tepals oblong or ovate, 3.5–4 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 3 locules, dehiscent. Fruit: seed surface type with knobbly colliculae, Quite different from the rest of the genus, 1.4 mm long, 0.8 mm in diameter, shape in side view elliptical, shape in diameter rectangular in cross section (tending towards rounded), silvery.
