    Plants densely cespitose.
    Culms dark maroon at base;
    flowering-stems 0.5–1.1 mm thick, 20–90 cm, much longer than leaves at maturity, glabrous, but often scabrous within inflorescence.
    Leaves: sheaths glabrous or short-pubescent, basal few bladeless and maroon, others grading from maroon to green on back, pale brown-hyaline, red dotted and sometimes pubescent near apex;
    blades flat, 3–9 mm wide, glabrous, minutely scabrous on margins distally.
    Inflorescences: peduncles of lateral spikes slender, to 40 mm, equaling spikes or usually somewhat shorter, scabrous;
    peduncle of terminal spike to 13 mm, glabrous or scabrous;
    proximal bracts shorter than inflorescences;
    sheaths 20–25 mm;
    blades 3–4 mm wide.
    Lateral spikes 2–5, 1 per node, well separated, drooping at maturity, pistillate with 10–45 perigynia attached 2 mm apart, linear, 10–70 × 2–3.5 mm.
    Terminal spike gynecandrous, 10–60 × 1–3 mm.
    Pistillate scales white-hyaline tinged with chestnut, broad green midrib often red dotted, sometimes scabrous, ovate to oblong, shorter than mature perigynia, apex rounded or cuspidate with ciliate awn less than 1 mm, otherwise glabrous.
    Perigynia green, usually red dotted, 2-ribbed and finely 8–12-veined, veins more obvious near base, ellipsoid to oblong-ovoid, loosely enveloping achenes, 2–3.7 × 1.3–1.6 mm, membranous, acute at base, tapering gradually to acute beakless apex, glabrous.
    Achenes substipitate, 1.2–2.6 × 1–1.2 mm. 2n = 50, 52, 54.
