    Culms to 150 cm × 5–10 mm.
    Leaves: sheaths reaching beyond or to middle of culm, fronts convex, papery at mouth, veins reaching apex;
    widest blade 6–13 mm wide.
    Inflorescences subumbellate, all or most spikelets solitary or in clusters of 2–7 on 3–11 rays, rays not exceeding 8 cm;
    involucral-bracts that surpass inflorescences 2–4, widest bract 2–8 mm wide.
    Spikelets 10–40, ovoid or lanceoloid, 15–40 × 5–6 (–8) mm;
    scales tightly appressed or in fruit usually loosely imbricate, medium to dark orangebrown, lineolate-spotted at 15X, 7–9 × 3–4 mm, papery, nearly opaque, apex 2-fid 0.5 mm deep, awn fairly stout, 2–3 × (0.3–) 0.5 mm at base.
    Flowers: perianth bristles weakly attached to shed achene or some to all falling separately, medium brown, 1/2 to equaling length of achene;
    anthers dark yellow to orange-yellow, 3.5–5 mm;
    styles (2–) 3-fid.
    Achenes dark to medium brown, color variable often on same achene, shape variable, often in same plant, markedly to obscurely trigonous with equally rounded angles to much compressedtrigonous with abaxial angle broadly rounded, or some biconvex in same spikelet, obovoid, 3–4.3 × 2.3–3.1 mm, apex rounded to nearly truncate, beak 0.1–0.5 mm, surface glossy or glossy with dull patches, entirely clearly cellular at 20X or faintly cellular to noncellular at 30X, often in patches;
    in cross-section exocarp 1/3–2/3 of mesocarp thickness and its cells variably enlarged, 1.5–3 times deeper than wide;
    achene specific gravity greater to less than water.
