Vegetative parts: plants forming long lines of culms, 0.15–0.45 m tall, with rhizomes. Rhizome long and slender, culms isolated and widely spaced, 1.2–2.8 mm in diam., culms 10–300 mm apart. Fertile culms much branched, round (not compressed), solid or with a small central cavity, smooth or finely warty, olivaceous, 0.14–0.45 m tall, diameter at base 0.6–1.6 mm, diameter at apex 0.3–0.5 mm. Sheaths more than 1 per culm, persistent, with no abscission line, closely convoluted, 1.5–4.5 mm long, light to dark brown, apical margins coriaceous, like the rest of the body, hyaline shoulders small, rounded, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, truncate. Sheath-mucro penicellate or hair-like (too wriggly to be penicillate), straight and erect or twisted, 0.5–1 mm long. Sterile branch leaf-sheath 2–3 mm long. Males: male inflorescence with 2–5 spikelets, racemose, 4–15 mm long, 1–1.5 mm wide. Male inflorescence spathes persistent, like the floral bracts or shorter than spikelets, coriaceous. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, elliptical, apex acute, 5–8.5 mm, 1–1.9 mm, with 10–25 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts as tall as flowers, 2–3.5 mm long, ovate, acute, cartilaginous, bract upper margin membranous, thinner texture than the body, bract awn less than half as long as the bract body. Male flower 2–3 mm long. Male tepals sepals and petals the same rigidity, chartaceous or membranous, oblong or elliptical, inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 0.5–1 mm long, exserted from the flowers. Females: female inflorescence with 1 spikelet. Female spathes shorter than the spikelets, persistent, coriaceous. Female spikelet sessile, elliptical, apex acute, 4–8 mm long, with 2–4 flowers, with 2 sterile bracts (subtending the spikelet). Female bracts as tall as flowers or taller than flowers, erect, 4–5 mm long, ovate, acute, coriaceous, apical margin like rest of bract, same as body of bract, margins entire, awn less than half as long as the bract body. Female flower 3–4.5 mm long, without a fleshy pedicel, six tepals. Female tepals coriaceous or chartaceous, keels of lateral sepals densely villous, midrib raised, margins entire, apices acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, hidden by bracts, or bracts are shorter than flowers, 3–4.5 mm long. Female odd outer tepal ovate, 3.5–4.5 mm long. Female inner tepals ovate, 3–4 mm long. Staminodes absent. Styles feathery, 2. Style bases fused to form a pillar. Ovary with 1 locule, dehiscent. Fruit: seed (4.72–)4.74(–4.76) mm long, (2.72–)3.1(–3.48) mm in diameter, shape in diameter somewhat flattened in cross section, silvery.
