Description Plants cespitose. Culms to 25–60(–100) cm, distally smooth or finely scabrous. Leaves 2–5 mm wide. Inflorescences: proximal bracts shorter than or exceeding inflorescences; spikes oblong or elongate, cylindric or clavate, 7–27 × 5–7 mm; lateral 2–4(–6) spikes pistillate, proximal ones usually erect, occasionally spreading or pendent, separate, pedunculate, distal ones overlapping, erect, contiguous, short-pedunculate; terminal spike gynecandrous, 1/3–2/3 staminate flowers, rarely staminate, sometimes appearing staminate due to fallen terminal perigynia. Pistillate scales dark brown to black, margins hyaline, lanceolate, typically shorter and narrower (equaling or slightly longer) than perigynia, midvein lighter colored than body, conspicuous, frequently raised, prominent, apex acute to short-mucronate. Perigynia ascending, pale green or pale yellow, veinless or obscurely veined, ovate, orbicular or obovate, 2.5–3.5 × 1.75–2.5 mm, apex abruptly beaked, smooth; beak 0.3–0.5 mm, shallowly or deeply bidentate, smooth. Achenes filling proximal 1/2 or less of perigynia. [details]
