Description Caespitose, phyllopodic perennial graminoid. Culms terete, slender, 208–580 × 0.2–0.8 mm. Leaves basal, 1–3, (16–)32–68(–153) × 0.2–0.9 mm, mostly straight, proximally channelled, margins usually serrate above the sheath. Sheaths usually firmly clasping the culm, sometimes but not always longitudinally striate. Ligule firm and relatively short, 0.2–1.0 mm long. Inflorescence a slender pseudolateral panicle, 11–43 × 3–8 mm; proximal rachis length 5–20 mm. Proximal primary inflorescence bracts slender, not channelled, apex acute, never widened at base, 24–60(–84) mm long, exceeding the length of the inflorescence by 0.5 times or more, without notable longitudinal veins. Proximal and subproximal primary inflorescence bracts never with membranaceous extensions at base. Spikes 2–14, (3.0–)7.0–16.0 mm long, sometimes overlapping. Spikelets lanceolate to slightly ovate, (2.2–)3.0–3.9(–4.1) × 1.0–1.2 mm, pedicellate, 2–5(–8) spikelets per spike, reddish-brown with hyaline margins and adjacent small reddish-brown streaks. Proximal spikelet prophyll 1 per spikelet, with a raised vein extending to mucro, 0.3–1.0 mm long; prophyll mucro variable in length, 0.7–2.2(–5.2) mm long. Rachilla (0.3–)1.4–2.2(–4.0) mm long. Glumes 6–8 per spikelet; proximal glume 0.3–1.2 mm long; subproximal glume 0.6–1.4 mm long; upper glumes longer than basal ones, apex acute to acuminate, lower glumes less than half the length of the spikelet. Glume mucros usually relatively short: proximal mucro 0.1–0.5(–1.5) mm long; subproximal mucro 0.1–0.7 mm long. Stamens (2–)3(–4) per floret, anthers 1.3–2.5(–4.3) mm long. Stigmas 3-branched; vestigial stigmas of the second bisexual floret sometimes present. Perianth bristles not observed. Nutlet broad elliptic, trigonous, yellowish in colour, 2.2–2.4 × 0.7–1.3 mm; nutlet beak 0.3–0.6(–1.5) mm long, hispid, purplish-brown when mature. [details]
