    Plants cespitose, in small and medium-sized clumps;
    Culms erect, not stiff, 15–90 cm.
    Leaves: sheaths pale-brown abaxially, inner band thin, hyaline, sometimes slightly red tinged, concave at summit;
    ligules slightly longer than wide;
    blades pale green to gray-green flat, 10–20 (–30) cm × (1.5–) 2–4 mm, subequal to shorter than culms, not stiff.
    Inflorescences 2–15 cm × 5–10 mm;
    proximal bracts shorter than to exceeding spikes;
    distal bracts usually scalelike.
    Spikes 4–8, gynecandrous, proximal ± remote, distal spikes approximate, sometimes flexuous, containing (5–) 10–20 (–30) perigynia suborbicular to oblong, 3–12 × 3–5 mm;
    terminal spike staminate for less than 1/2 of length, often clavate due to more conspicuous staminate part.
    Pistillate scales hyaline with green, 3-veined center when young, usually brownish tinged in age, broadly ovate, subequal to, not concealing perigynia, apex obtuse to acutish.
    Perigynia appressed-ascending, gray-green, becoming yellowish-brown, obscurely many-veined, elliptic-ovate, 1.8–3 × 1.2–1.7 mm, widest near middle, membranous;
