Description Culms 35–87 cm tall, somewhat wiry and flexuous or not, erect, arching or ± decumbent, 0.2–0.65 (–0.85) mm wide at ca. 1 cm below the inflorescence, prominently scabrous- or ciliate-angled; bladeless basal sheaths brown to red or dark purple.

Pistillate scales 1.8–3.4 mm long; staminate scales 3–4.8 mm long. Perigynia 3–4.1 (–4.6) mm long. Achenes 2–2.6 mm long. Anthers 1.7–2.3 mm long. [details]
