    Rhizomes often vertical, 1–6 mm diam., firm to hard;
    scales shorter to longer than internodes, disintegrating to fibers.
    Culms sharply trigonous, sides convex to concave proximally, deeply concave to flat distally, 0.1–2 m × 1–6 mm, smooth.
    ligules 2-fid, 1 mm;
    blades 2–6, proximally V-shaped, distally trigonous to asymmetrically laterally flattened in cross-section, angles often scabridulous distally;
    distal blade (1–) 2–5 times as long as sheath, 50–750 × 2–9 mm.
    Inflorescences capitate;
    proximal bract usually erect, resembling leaf-blade but trigonous proximally, (1–) 3–20 cm.
    Spikelets 1–5 (–10), 5–23 × 3–5 (–7) mm;
    scales bright (to very dark) orange, redbrown, or purplish brown to straw-colored, often prominently lineolate-spotted, midrib mostly paler, ovate, 3.5–6 × 2–3 mm, smooth or awn sparsely spinulose, margins deciduously ciliolate, flanks ribless except sometimes proximal scales, midrib prominent, apex acute (to obtuse), 2-fid, notch (0.3–) 0.5–1 mm deep, awn mostly irregularly bent, 0.5–1.5 (–2.5) mm.
    Flowers: perianth members 4–8, sometimes fewer, brown, bristlelike, variably slender to stout, equal or unequal, all equaling achene body to all rudimentary, retrorsely spinulose;
    anthers 2–3 mm;
    styles 2–3-fid.
    Achenes brown, biconvex to compressed bluntly trigonous, obovoid to obpyriform, (2–) 2.5–3.5 × 1.3–2.3 mm;
    beak 0.1–0.5 mm. 2n = 74, 78.
