Description Plants densely to loosely cespitose; rhizomes short, no more than 10 cm. Culms trigonous in cross section, 20–100 cm, scabrous-angled distally. Leaves: basal sheaths usually strongly tinged with reddish purple; ligules longer than wide; blades pale to mid green, flat to W-shaped, 2.5–8.5 mm wide, glabrous. Inflorescences 2.5–12(–20) cm; proximal bract 4–30 cm, exceeding inflorescence; proximal (1–)2–3(–4) spikes pistillate, erect or often the proximal pendent; terminal 1 spike staminate. Pistillate scales lanceolate, 2.3–6.5 × 0.5–1.1 mm, shorter than perigynia, margins ciliate, , apex truncate to retuse, scabrous-awned, awn longer than body. Staminate scales scabrous-awned, sometimes also ciliate-margined. Perigynia spreading or the proximal reflexed, strongly 13–21-veined, veins mostly separated by 3+ times their width, confluent at or proximal to mid beak (except for 2 prominent lateral), elliptic, 4.5–7.3 × 1.4–2.1 mm, herbaceous, apex contracted; beak 1.9–2.8 mm, smooth, bidentulate, teeth straight, 0.3–0.9 mm. Stigmas 3. Achenes pale brown, trigonous, smooth. [details]
