Plants densely to loosely cespitose; rhizomes short, no more than 10 cm. Culms sharply trigonous in cross section, (15–)25–95(–110) cm, scabrous-angled distally. Leaves: basal sheaths reddish purple; ligules as wide to slightly longer than wide; blades dark green, flat to W-shaped, widest leaves (4–)4.5–11.5(–13) mm wide, glabrous. Inflorescences 2.7–18 cm; proximal bract 9–45 cm, exceeding inflorescence; proximal 1–3(–4) spikes pistillate, erect or the proximal often spreading, (12–)15–22 mm thick, if spikes less than 15 mm thick, then usually less than 2.5 times as long as wide; terminal 1 spike staminate. Pistillate scales narrowly oblong, 3.4–11.2 × 0.5–1.1 mm, as long as or shorter than perigynia, margins often ciliate, apex truncate to retuse, erose, prolonged to scabrous awn. Staminate scales with distinct, scabrous awn, sometimes ciliate-margined. Perigynia spreading, strongly 7–12-veined, veins separate nearly to beak apex, broadly ovate, (6–)6.5–10.8 × (1.8–)2–3.5(–4.2), apex contracted; beak 2.5–5.9 mm, 0.7–0.9 length of body, bidentate, smooth, teeth straight, to 0.2–0.8 mm. Stigmas 3. Achenes yellow to brown, trigonous, papillose.
Phenology: Fruiting May–Aug.
Habitat: Wet meadows, marshes, seeps, shores of ponds, lakes, and streams, open swamp forests, ditches, mostly in acidic, often sandy soils
