    upland
    dry to mesic deciduous forests
    Plants densely cespitose.
    Culms dark maroon at base;
    flowering-stems 20–100 cm, much longer than leaves at maturity, 0.6–1 mm thick, glabrous but scabrous within inflorescence.
    Leaves: basal sheaths maroon, bladeless, rarely minutely scabrous, glabrous;
    blades flat, 3–10 (–13) mm wide, glabrous with minutely scabrous margins.
    Inflorescences: peduncles of lateral spikes slender, to 30 mm, shorter than spikes;
    peduncle of terminal spike to 28 mm, usually shorter than adjacent pistillate spikes, minutely scabrous on angles;
    proximal bracts shorter than inflorescences;
    blades 2–3 mm wide.
    Lateral spikes 2–5, 1 per node, well separated, erect at anthesis, but soon drooping, pistillate with 15–45 perigynia attached 1–2 mm apart, linear-elongate, 25–80 × 3–4 mm.
    Terminal spike staminate, sessile or pedunculate, 6–40 × 0.8–2 mm.
    Pistillate scales white-hyaline with green midrib, oblong-lanceolate, shorter than mature perigynia, apex acuminate to cuspidate or awned, awn to 1.5 mm, margins and awn scabrous or ciliate, otherwise glabrous.
    Perigynia green, often red dotted, 2-ribbed and finely 10–15-veined, loosely enveloping achene, ellipsoid-ovoid, 3–5 × 1–2 mm, membranous, base with stipe 2–3 mm, apex tapering to minute beak, glabrous but sometimes ciliate between apical teeth;
    beak bidentate, 0.7–1.5 mm.
    Achenes sessile, 1.7–2.6 × 0.8–1.7 mm. 2n = 52, 54, 56.
