    Culms 50–150 cm × (1–) 3–8 mm.
    Leaves: sheaths reaching ± to mid culm, fronts usually membranous at mouth, apex concave to convex, veins diverging proximal to summit leaving triangular, veinless area (often disintegrating);
    widest blade 2–12 mm wide.
    Inflorescences with all spikelets sessile, simply branched with not more than 1/2 of spikelets solitary or in clusters of 2–10 on 1–4 rays, rays not exceeding 8 cm;
    involucral-bracts that surpass inflorescences 1–4, widest bract 1–6 mm wide.
    Spikelets (1–) 2–40, ovoid to lanceoloid, 7–40 × (4–) 7–10 mm, base usually cuneate to rounded;
    scales often loosely imbricate, bright orangebrown to stramineous, often obscurely lineolate-spotted, 5–8 × 3–4 mm, membranous, translucent, apex acute, 2-fid 0.5–1 mm deep, awn slender, 1–3 × 0.25 mm at base.
    Flowers: perianth bristles not persistent on shed achenes or sometimes 1–few weakly persistent, medium brown, to 1/2 achene length;
    anthers yellow, very rarely orange, 2–4 mm;
    styles 2–3-fid.
    Achenes medium to dark-brown, rarely yellowish or whitish, obovoid, biconvex, or concavesided, rarely obtusely compressed trigonous, 2.3–4.1 × 1.9–2.8 mm, apex rounded to nearly truncate, beak 0.1–0.4 mm, surface glossy, exocarp (epidermal) cells usually clearly visible at 10–20X;
    in achene cross-section exocarp 2 times as thick as mesocarp, its cells greatly enlarged, at least 3 times deeper than wide;
    achene specific gravity much less than water.
