Vegetative parts: plants tangled, 0.2–0.4 m tall, basal diameter 0.1–1 m, crown diameter 0.1–1 m, with stolons. Fertile culms branching, smooth or finely rugulose, olivaceous, 0.2–0.5 m tall, diameter at base 0.3–0.8 mm, diameter at apex 0.1–0.2 mm. Sheaths closely convoluted, 6–15 mm long, yellow-brown, apical margins broadly membranous, hyaline shoulders membranous margins continuing behind awn, hyaline shoulder 0.1 of sheath body length, apex, excluding the membranous lobes, acuminate or acute. Sheath-mucro awl- or needleshaped, straight and erect, 2–4 mm long, pale body grades into membranous margins. Males: male inflorescence with 1 spikelet (Very rarely more than one, and these might constitute a distinct species). Male inflorescence spathes persistent, like the floral bracts, chartaceous, slightly darker than the floral bracts. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex rounded or undifferentiated, 7–17 mm, 5–12 mm, with 2–8 flowers, pedicels absent ie spikelets sessile. Male bracts more than twice as tall as flowers, 5–12 mm long, linear or oblong or ovate, acute or aciculate (the fine aciculate tip is lost readily), lax, chartaceous, bract upper margin like body of bract, bract awn minute or absent or less than half as long as the bract body, yellow-brown, slender. Male flower 2.2–3 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, glabrous. Anthers 1–1.5 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence with 1 spikelet. Female spathes shorter than the spikelets (very similar to the bracts), persistent, chartaceous. Female spikelet sessile, oblong, apex rounded or undifferentiated, 6–12 mm long, with 1 flowers, with 0 sterile bracts. Female bracts at least twice as long as flowers, 5–12 mm long, linear or oblong or ovate, acute or aciculate, chartaceous, apical margin like rest of bract, same as body of bract, lax, exposing spikelet axis, awn minute or absent or less than half as long as the bract body. Female flower 2.5–3 mm long, oblique, without a fleshy pedicel. Female tepals chartaceous, keels of lateral sepals sparsely villous (often only on one sepal, or if both, then on one sepal the hairs weakly fused into a wing), midrib flush with the tepal body, apices rounded or obtuse, inner and outer whorls the same length. Female outer lateral tepals like other tepals or conduplicate, 2.5–3 mm long. Female odd outer tepal oblong, 2.5–3 mm long. Female inner tepals oblong, 2.5–3 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent or capsules thinwalled, sometimes dropping with seed in. Fruit: seed (1.2–)1.3(–1.36) mm long, (0.48–)0.73(–0.88) mm in diameter, shape in side view elliptical, shape in diameter round in cross section, yellow, smooth.
