Vegetative parts: plants tangled, 0.2–0.35 m tall, compact, without spreading rhizomes or stolons. Fertile culms branching, round (not compressed), solid or with a small central cavity, roughly warty, olivaceous, 0.2–0.35 m tall, diameter at base 0.8–1.2 mm, diameter at apex 0.5–1 mm. Branch axil indumentum absent. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths more than 1 per culm, persistent, with no abscission line, loosely convoluted, 8–28 mm long, margins entire, orange to pinkish/red with tan at the edges, upper 1/3 in colour and texture similar to the lower 2/3, apical margins broadly membranous, hyaline shoulders tall, acute, apex, excluding the membranous lobes, truncate. Sheath-mucro penicellate, straight and erect, 1.5–8 mm long. Males: male inflorescence with 2–5 spikelets or 6–10 spikelets, racemose (singlee spikelets occurring at the tip of culms - these may be side branches of a main culm axis), 50–150 mm long, 5–13 mm wide. Male inflorescence spathes persistent, shorter than spikelets, cartilaginous. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, obovate or undifferentiated, apex undifferentiated, 9–14 mm, 3–5 mm, with 5–10 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 8–9.5 mm long, elliptical (relatively broad in the middle), rounded, margins entire, coriaceous (but quite thin, though not membranous), bract upper margin membranous, thinner texture than the body, bract awn less than half as long as the bract body. Male flower 5–7 mm long. Male tepals sepals and petals the same rigidity, chartaceous, oblong or elliptical (outer tepals are oblong and inner ones elliptical), inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 2–2.5 mm long, exserted from the flowers. Females: female inflorescence interrupted or linear, 50–120 mm long, 5–10 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes shorter than the spikelets, persistent, coriaceous or cartilaginous. Female spathellae inconspicuous or absent. Female spikelet sessile, undifferentiated, apex undifferentiated, 7–12 mm long, with 4–5 flowers, with 0 sterile bracts. Female bracts taller than flowers, erect, 8–10 mm long, oblong, rounded, chartaceous or cartilaginous, apical margin membranous, same as body of bract, awn less than half as long as the bract body. Female flower 6–8.5 mm long, without a fleshy pedicel, six tepals. Female tepals chartaceous, midrib flush with the tepal body, margins entire, apices acute, inner whorl shorter than outer (slightly). Female outer lateral tepals conduplicate, 3–4.5 mm long. Female odd outer tepal oblong, 3–4.5 mm long. Female inner tepals elliptical or ovate, 2.7–3.8 mm long. Staminodes absent. Styles feathery, red, 2. Style bases fused to form a pillar. Ovary dehiscent. Fruit: seed (1.24–)1.36(–1.48) mm long, (0.84–)1(–1.16) mm in diameter, shape in side view elliptical or oblong, shape in diameter round in cross section, brown or white (this depends on how translucent/opaque the seedcoat is), colliculate (with small pimply tubercles).
