    Plants with short rhizomes, loosely cespitose.
    Culms dark maroon at base;
    flowering-stems 40–90 cm, much longer than leaves at maturity, 0.5–1 mm thick, sparingly pilose.
    Leaves: basal sheaths maroon, bladeless, pilose;
    blades flat, 2.5–9 mm wide, pilose on both surfaces, sparsely so adaxially, margins smooth or ciliate.
    Inflorescences: peduncles of lateral spikes capillary, 10–20 mm, glabrous or pubescent;
    peduncle of terminal spike erect, 3–5 mm;
    proximal bracts hyaline, reduced to green awn or less often leaflike and 0.3–1.5 mm wide;
    sheaths usually less than 3 mm (to 10 mm).
    Lateral spikes 2–4, 1 per node, mostly near apex but not crowded, drooping at maturity, pistillate with 10–40 perigynia attached 1 mm apart, narrowly cylindric, 8–25 × 4–5 mm.
    Terminal spike staminate, sessile or pedunculate, 10–30 × 1.4–3 (4) mm.
    Pistillate scales hyaline suffused with chestnut with broad green midrib, ovate, shorter to nearly as long as mature perigynia, apex acute to cuspidate, awns less than 1 mm, often ciliate distally.
    Perigynia light green, usually red dotted, 2-ribbed and 5–7-veined, at least proximally and abaxially, loosely enveloping achene, ellipsoid, 2.5–5 × 1.3–2.5 mm, membranous, base acute, apex tapering to beak, glabrous;
    beak bidentate to 1.5 mm, teeth 0.5 mm, ciliate between apical teeth.
    Achenes substipitate, 1.5–2 × 1–1.5 mm. 2n = 44, 64.
