Vegetative parts: plants tangled (Often pendulous from ledges), 0.2–0.5 m tall, with stolons. Fertile culms branching, finely rugulose, olivaceous, 0.2–0.8 m tall, diameter at base 0.4–1 mm, diameter at apex 0.1–0.3 mm. Sheaths closely convoluted, 10–25 mm long, pale brown, apical margins narrowly membranous, hyaline shoulders small, rounded or membranous margins continuing behind awn, hyaline shoulder 0.01 of sheath body length, apex, excluding the membranous lobes, acute. Sheath-mucro penicellate, straight and erect, 2–10 mm long, awns often quite prominent. Males: male inflorescence with 1 spikelet or 2–5 spikelets, racemose, 15–50 mm long, 6–10 mm wide. Male inflorescence spathes persistent, like the floral bracts, chartaceous, almost indistinguishable from floral bracts. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong or obtriangular, apex rounded or obtuse, 12–20 mm, 6–10 mm, with 8–12 flowers, pedicels absent ie spikelets sessile. Male bracts taller than flowers, 7–13 mm long, oblong, acute, lax (very rarely) or imbricate, chartaceous, bract upper margin like body of bract, bract awn minute or absent, much taller than the flowers. Male flower 3–3.4 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, glabrous or keel sparsely villous. Anthers 1.2–1.5 mm long, exserted from the flowers. Pistillode present. Females: female inflorescence racemose, 15–40 mm long, 3–8 mm wide, with 1 spikelet or 2–5 spikelets. Female spathes insignificant (almost indistinguishable from the bracts), persistent, chartaceous. Female spikelet sessile, oblong or elliptical or obtriangular, apex truncate, 12–20 mm long, with 3–8 flowers, with 0 sterile bracts. Female bracts taller than flowers, 5–15 mm long, oblong, acute, chartaceous, apical margin like rest of bract, same as body of bract, awn minute or absent. Female flower 2.5–4.2 mm long, oblique, without a fleshy pedicel. Female tepals chartaceous or cartilaginous, scabrid all over or keels of lateral sepals sparsely villous or keels of lateral sepals densely villous, midrib flush with the tepal body, apices obtuse or acute, inner and outer whorls the same length. Female outer lateral tepals conduplicate, 2.2–4 mm long. Female odd outer tepal oblong, 2.2–4 mm long. Female inner tepals oblong, 2.2–4 mm long. Staminodes present. Styles feathery, white, 3. Style bases free. Ovary with 1 locule, dehiscent or indehiscent. Fruit: elaiosome absent. Seed (1.04–)1.08(–1.12) mm long, (0.56–)0.57(–0.6) mm in diameter, shape in side view obovate, shape in diameter triangular in cross section, tan.
