Description Plants loosely cespitose. Culms 20–70 cm, distally finely scabrous. Leaves 2.5–5 mm wide. Inflorescences: proximal bracts shorter than or exceeding inflorescences; spikes distinct, spreading or the proximal pendent and often separate, elongate, 10–25 × 5–8 mm; lateral 3–6 spikes pistillate, long-pendunculate; terminal spike gynecandrous. Pistillate scales light to dark brown with hyaline margins, lanceolate, longer than and as broad as perigynia, midvein same color as body, inconspicuous or lighter in color, conspicuous, raised, prominent, sometimes short-mucronate. Perigynia ascending, yellow brown or chestnut, veinless, ovate or elliptic, 2.5–3 × 1.5–1.75 mm, apex abruptly beaked, distally papillose; beak 0.4–0.5 mm, bidentate, smooth. Achenes filling proximal 1/2 or less of perigynia. [details]
