Plants densely cespitose, also producing long-arching stolons that root at the tip and form new plants. Culms dark maroon at base; flowering stems 35–75 cm, longer than leaves at maturity, 0.5–0.8 mm thick, glabrous or minutely scabrous on angles, especially within inflorescence. Leaves: basal sheaths maroon, bladeless, glabrousl; others grading from maroon to green on back, pale hyaline on front; blades flat, 1–3 mm wide, glabrous on adaxial surface, often strigose on abaxial surface, margins and midribs of abaxial surface scabrous at distal end. Inflorescences: peduncles of lateral spikess 20–60 mm, glabrous; peduncle of ternimal spike 40–60 mm, glabrous or minutely scabrous on angles; proximal bracts much shorter than inflorescence; sheaths 15–25 mm; blades 1.5–2.2 mm wide. Lateral spikes 2–5, pistillate with fewer than 10 perigynia attached 3–15 mm apart, 1 spike per node, well separated, erect or drooping, linear, 5–30 × 3–5 mm; distal spikes sometimes staminate and shorter than terminal spike. Terminal spike staminate, 11–30 × 1.5–3 mm. Pistillate scales pale hyaline, often partially suffused with chestnut brown, with narrow green midrib, lanceolate to oblong, shorter than ma
