Description Tall but slender perennial, tufted, often with rather long surculi and a thickened somewhat bulbous base, 40–110 cm high, not viscid. Culms trigonous to triquetrous, often slightly scabrous, 1–2.5 mm diam. Leaves flat to carinate or canaliculate, usually not septate-nodulose, shorter than culms, to 3.5 mm wide; midrib ± obvious abaxially, usually smooth; marginal prickles dense to sparse, mostly regularly spaced (0.1–0.6(–1.1) mm apart), long to short, (0.05–)0.1–0.2 mm long, antrorse, aculeate; leaf sheaths usually not septate-nodulose, finely striate, not shining, stramineous above, purple-red below. Inflorescence simple or small-compound, 4–12 primary branches to 10 cm long; bracts suberect to spreading, 2–3 much exceeding the inflorescence. Spikelets c. 12 in loose, spicate to subdigitate, hemispherical clusters of 0.7–2.5 cm diam.; spikelets compressed, oblong to narrow-ovate, 5–13(–18) mm long, 1.5–3 mm wide in side view, 4–14(–18)-flowered; rachilla not thickened, not or narrowly winged, wings to 0.05 mm wide; glume spacing 1.1–2.3 mm; spikelet falling as a unit, or rachilla persistent and glumes falling individually. Glumes narrow-elliptic to narrow-ovate, acute with straight mucro <0.1–0.3 mm long, stramineous to golden to red-brown with green midrib, 2.5–3.8 mm long, 0.5–1.0 mm wide, sides (1–)2–4-nerved, margins inrolled and narrow-membranous. Anthers 1.3–2.3 mm long excluding appendage ≤0.1(–0.2) mm long. Nut trigonous, very narrow-elliptic with acute apex, faces flat to convex, pale brown, shortly elongate-colliculate to foveate, glistening or shining, 1.7–2.2 mm long, ½–¾ length of glume, 0.3–0.7 mm diam., falling with glume.
