Description Plants perennial, densely tufted; rhizomes mostly hidden by aerial shoots and roots, not long, 2–3 mm thick, hard, cortex persistent?, internodes very short, scales persistent, 4–7 mm, membranous, slightly fibrous. Culms terete, when dry with to 12 blunt ribs, 20–55 cm × 0.5–1.1 mm, soft to firm, internally mostly hollow with complete transverse septa 2–4 mm apart, evident only on sectioning culm. Leaves: distal leaf sheaths persistent, not splitting, proximally dark red, distally stramineous or reddish, thinly papery, apex often red to brown, obtuse to subtruncate, slightly callose, tooth present, 0.5–1(–3.7) mm. Spikelets lanceoloid, 5–13 × 2–2.5 mm, apex acute to obtuse; proximal scale amplexicaulous, entire; subproximal scale empty; floral scales appressed in fruit, 10–100, 10–12 per mm of rachilla, medium brown to stramineous, midrib regions often greenish, ovate, 1–1.5 × 1 mm, entire, apex rounded to subacute, carinate in distal part of spikelet. Flowers: perianth bristles 5–6, pale brown, stout, equaling achene; stamens 3; anthers brown, 0.4–0.9 mm; styles 3-fid or a few 2-fid in the same spikelet. Achenes falling with scales, green or medium or dark brown, obpyriform, compressed-trigonous or some biconvex in same spikelet, angles prominent, 0.6–0.8 × 0.5–0.6 mm, neck short or absent, smooth or very finely reticulate at 20–30X. Tubercles brown, depressed-pyramidal, 0.1–0.2 × 0.2–0.3 mm. [details]
