Vegetative parts: plants tufted or mat-Forming or tangled, 0.3–0.5 m tall, with stolons. Fertile culms branching, smooth or finely rugulose, olivaceous, 0.3–0.6 m tall, diameter at base 0.5–2 mm, diameter at apex 0.4–1 mm. Sheaths closely convoluted, 13–25 mm long, pale-brown, apical margins narrowly membranous, hyaline shoulders membranous margins continuing behind awn, hyaline shoulder 0.05 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 2–7 mm long, awns well developed, closely adpressed to culm. Males: male inflorescence with 2–5 spikelets, racemose or paniculate (rarely), 20–60 mm long, 10–15 mm wide. Male inflorescence spathes persistent, like the floral bracts, coriaceous, spathes darker in colour than bracts. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or elliptical or obtriangular, apex rounded or acute, 14–25 mm, 5–10 mm, with 5–8 flowers, pedicels absent ie spikelets sessile. Male bracts more than twice as tall as flowers, 8–12 mm long, oblong, acute, chartaceous, bract upper margin like body of bract, bract awn minute or absent, pale brown, striking. Male flower 2.5–4 mm long. Male tepals sepals more rigid than petals, chartaceous, petals membranous, linear or oblong, inner and outer tepals the same length. Male outer lateral tepals conduplicate, keel sparsely villous. Anthers 1–2.4 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence racemose, 10–60 mm long, 5–10 mm wide, with 1 spikelet or 2–5 spikelets (rarely). Female spathes shorter than the spikelets (very similar to the bracts), persistent, coriaceous. Female spikelet sessile, elliptical or obovate or obtriangular, apex truncate or rounded, 10–25 mm long, with 3–6 flowers, with 0–1 sterile bracts. Female bracts at least twice as long as flowers, 7–15 mm long, oblong, acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 3.2–3.8 mm long, oblique, without a fleshy pedicel. Female tepals chartaceous, keels of lateral sepals sparsely villous (only one lateral sepal bearded), midrib flush with the tepal body, apices obtuse or acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 3–3.8 mm long. Female odd outer tepal oblong, 3–3.8 mm long. Female inner tepals oblong, 3–3.8 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent (tardily dehiscent, but the ovary is readily opened to extract the seed). Fruit: seed (1.28–)1.56(–1.84) mm long, (0.72–)0.85(–0.96) mm in diameter, shape in side view elliptical, shape in diameter triangular in cross section, tan, smooth (shiny).
