Description Plants colonial; rhizomes long-creeping. Culms central, slender, trigonous, 25–60 cm, papillose and scabrous-angled distally. Leaves: basal sheaths brown, bladeless, rapidly disintegrating into fibers; ligules 0.7–1.5 mm, wider than long; blades somewhat glaucous, M-shaped, 1.5–3.2 mm wide, papillose abaxially. Inflorescences 2.5–12 cm; rachis beyond proximal pistillate spikes sharp-angled, often finely scabrous; proximal (1–)2–3(–4) spikes pistillate, not or barely overlapping, ascending; distal spikes erect; terminal 1 spike staminate. Pistillate scales ovate to broadly ovate, apex acute to acuminate-awned, awn to 1.3 mm, glabrous. Perigynia ascending, essentially veinless except for 2 marginal veins, ovoid, 3.1–4.5 × 1.7–2.5 mm, glabrous; beak 0.4–0.8 mm, bidentulate, teeth straight, 0.2–0.3 mm. [details]
