Description Culms 100–200 cm × 5–15 mm. Leaves: sheaths reaching to middle of culm or higher, fronts convex (to concave) and papery at mouth, veins reaching apex, very rarely diverging leaving triangular, veinless, membranous area; widest blade 7–22 mm wide. Inflorescences subumbellate, with all or most spikelets solitary or in clusters of 2–3(–8) on 4–12 rays, rays not exceeding 10 cm; involucral bracts that surpass inflorescences 3–6, widest bract 4–15 mm wide. Spikelets 10–40, ovoid to lanceoloid, 10–25 × 6–10 mm, base cuneate to rounded; scales often loosely imbricate, orange-brown to stramineous, usually obscurely lineolate-spotted, 7–10 × 3–4 mm, membranous and translucent, apex 2-fid 0.5–1 mm deep, awns fairly stout, 2–3 × 0.5 mm wide at base. Flowers: perianth bristles tightly attached to shed achene, pale brown, very stout, equaling achene; anthers yellow, 4 mm; styles 3-fid. Achenes grayish or dark brown, often in patches, obovoid to obpyriform, all nearly equilaterally markedly trigonous to slightly compressed, angles equally rounded, 3.8–5.5 × 2–2.9 mm, apex rounded, beak 0.2–0.8 mm, surface rather dull, exocarp cells usually not evident at 20X; in cross section exocarp much thinner than mesocarp and its cells very small, isodiametric; achene specific gravity greater than water. 2n = 94.

Description Rhizomatous perennial. Culms 100–200 cm high, 5–10 mm diam. Leaves 7–11 mm wide. Inflorescence with 6–9 branches 2–10 cm long, bearing clusters of 1–6 spikelets; involucral bracts 15–25 cm long, 3–6 mm wide. Spikelets 1–2.5 cm long. Glumes 6–7 mm long (plus mucro 1.5–3 mm long), yellow-brown. Hypogynous bristles about as long as nut, usually persistent. Style 3-fid. Nut equally trigonous, with dorsal angle acute, 3–4 mm long, 1.5–2 mm diam., pale yellow or grey and dull to blackish and shining, minutely (but often obviously) reticulate. [details]
