Description Big tussock-forming perennial. Culms terete or somewhat compressed, striate but smooth, glabrous, often 1 m or more high, 1–2.5 mm diam. Leaves with blade often 50 cm long, 1–2.5 mm wide; sheath striate but shining, greyish yellow-brown. Inflorescence 1.5–2 cm diam.; involucral bracts usually 3, broad and sheathing at base, to about as long as inflorescence. Glumes obovate to broad-elliptic, glistening, yellow-brown, papery with thinner wavy, erose margin; lowest 3 or 4 glumes more or less broad-oblong, much shorter than upper; uppermost 3 glumes 5–5.5 mm long, the lowest of these 3 closely enveloping the other 2 much narrower glumes. Bristles somewhat longer than nut, usually remaining with inflorescence. Anthers 2.5–3 mm long; apical appendage 0.3–0.7 mm long. Nut (rarely collected) obovoid to broad-ellipsoid, 3.0–3.5 mm long, 1.6–1.8 mm diam., the loose outermost layer grey-brown, sparsely hispidulous at apex and base of style or glabrous; the inner nut c. 2.5 mm long with shining, slightly wrinkled and minutely reticulate, pale red-brown surface.
