Vegetative parts: plants tufted, 0.5–1 m tall, compact, without spreading rhizomes or stolons. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth, olivaceous, 0.5–1 m tall, diameter at base 1–1.5 mm, diameter at apex 0.7–1.2 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, 10–20 mm long, margins entire, greenish, with a brown upper third, upper 1/3 in colour and texture abruptly different from the base, and soon decaying, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, acute or obtuse. Sheath-mucro absent. Males: male inflorescence with 11–20 spikelets or 21–50 spikelets, paniculate, 60–190 mm long, 20–30 mm wide. Male inflorescence spathes persistent, taller than spikelets, chartaceous, 10–25mm long. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or ovate, apex obtuse or undifferentiated, 5–10 mm, 5–6 mm, with 15–20 flowers, pedicels shorter than the spikelets, terete or angular. Male bracts more than twice as tall as flowers, 7–12 mm long, linear or ovate, acuminate, margins entire, chartaceous or membranous, bract upper margin membranous, thinner texture than the body or like body of bract, bract awn minute or absent, Bracts may be quite stiff, almost cartilaginous. Male flower 3.5–4 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 1.75–2 mm long, included in the flowers. Pistillode present. Females: female inflorescence linear, 30–120 mm long, 15–30 mm wide, with 6–10 spikelets or 11–20 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent, chartaceous (10–30mm long). Female spathellae inconspicuous or absent. Female spikelet pedicel simple, oblong, apex rounded or obtuse or undifferentiated, 6–15 mm long, with 12–15 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, erect, 10–15 mm long, linear or ovate, acuminate, hyaline or cartilaginous, apical margin like rest of bract, paler than body of bract, margins entire, awn minute or absent. Female flower 4.5–5.5 mm long, without a fleshy pedicel, six tepals. Female tepals bony 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, 3–3.5 mm long. Female odd outer tepal elliptical or ovate, 2.5–3.25 mm long. Female inner tepals oblong, 4–4.5 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 3 locules or 2 locules, dehiscent (seed 1.25 x 0.75mm with lengthwise striations/wrinkles). Fruit: seed (1.28–)1.39(–1.56) mm long, (0.8–)0.91(–1) mm in diameter, shape in side view elliptical, shape in diameter round in cross section, brown; funicular elaiosome absent.
