Leaves: basal sheaths reddish purple; ligules longer than wide; blades pale to mid green, flat to W-shaped, 3.5–9 mm wide, glabrous. Inflorescences 6–25 cm; proximal bract 15–40 cm, exceeding inflorescence; proximal 3–4 spikes pistillate, erect or the proximal spreading; terminal 1–2 spikes staminate. Pistillate scales ovate, obtuse to acuminate, 2–4.4(–5.1) × 0.7–1.3 mm, shorter than perigynia, margins erose, apex contracted, scabrous-awned, awn mostly shorter than body. Staminate scales scabrous-awned, sometimes also ciliate-margined. Perigynia ascending, ca. 13–25-veined, veins separated by 3+ times their width, confluent at or proximal to mid beak (except for 2 prominent lateral), narrowly elliptic, 3.1–4.8 × 0.9–1.5(–1.8) mm, herbaceous, apex tapered; beak 0.9–1.8 mm, smooth, bidentulate, teeth straight, 0.4–0.9 mm.
