Plants cespitose. Culms 10–40 cm, smooth. Leaves 3–4 mm wide. Inflorescences: proximal bracts shorter than, sometimes equaling or, occasionally, exceeding inflorescences; spikes overlapping, contiguous, forming a dense terminal cluster or, sometimes, proximal spikes separate and distinct, sessile, short-oblong, 7–10 × 5–7 mm; lateral 2–3 spikes pistillate; terminal spike gynecandrous. Pistillate scales dark-brown or black to margins, lanceolate, shorter or longer than, and narrower than, perigynia, midvein same color as body, inconspicuous, apex usually acute, occasionally short-mucronate. Perigynia ascending, glossy reddish-brown, often with yellowish or greenish brown margins, veinless, obovate or circular, 3.5–4.5 × 2.5–3 mm, apex abruptly beaked, smooth; beak 0.5–0.8 mm, deeply bidentate, smooth. Achenes filling proximal 1/2 or less of perigynia.


Phenology: Fruiting Jul–Aug.
