Plants loosely cespitose, long-rhizomatous. Culms 10–30 cm, distally finely scabrous. Leaves 1.5–3 mm wide. Inflorescences: proximal bract shorter than or equaling inflorescences; spikes contiguous, overlapping, short-oblong or cylindric, 3–8 × 2–2.5 mm; proximal spikes sometimes erect, distinct, separate, short-pendunculate; lateral 1–2(–3) spikes pistillate, of similar length; terminal spike staminate, spikes can be hidden by larger, overtopping lateral spikes. Pistillate scales dark brown or black, margins hyaline, ovate, shorter or equaling, as broad as perigynia, midvein lighter colored than body, conspicuous, sometimes raised, prominent, mucronate. Perigynia ascending, brown, obscurely veined, elliptic or obovate, 2–2.5 × 1.25–1.75 mm, apex beakless or abruptly beaked, papillose; beak to 0.2 mm, truncate, smooth. Achenes nearly filling body of perigynia. 2n = 60.
