Description Plants densely cespitose. Culms 10–30 cm, distally finely scabrous. Leaves 2.5–5 mm wide. Inflorescences: proximal bracts shorter than or exceeding inflorescences; spikes contiguous, overlapping, erect, distinct, short-pendunculate, short-oblong or elongate, 8–20 × 4–7 mm; lateral 1–3 spikes pistillate pedunculate, of similar length; terminal spike gynecandrous. Pistillate scales light to dark brown with hyaline margins, broadly lanceolate or ovate, equaling perigynia, midvein same color as body, inconspicuous, raised, prominent, short-mucronate. Perigynia ascending, chestnut, veinless, ovate, 3–3.5 × 2–2.5 mm, apex abruptly beaked, papillose; beak 0.3–0.4 mm, entire or shallowly bidentate, smooth. Achenes nearly filling body of perigynia. 2n = 52, 54. [details]
