    Plants densely cespitose, in small clumps;
    Culms erect to arching, slender, 15–90 cm.
    Leaves: sheaths relatively tight, pale to mid brown abaxially, inner band thin and hyaline, often concave at summit;
    ligules as long as wide;
    blades green to yellowish green, flat, 10–25 (–40) cm × 0.5–2 mm, shorter than culms.
    Inflorescences erect to somewhat nodding, 1.5–7 cm × 3–6 mm;
    proximal bracts bristlelike-prolonged, shorter than to exceeding spikes;
    distal bracts usually scalelike.
    Spikes 5–10, gynecandrous, proximal ± separate, distal closely approximate, containing 5–10 perigynia, sessile, globose to short-oblong, 3–7 × 3–4 mm;
    terminal spike staminate for less than 1/2 of length, scarcely clavate.
    Pistillate scales white-hyaline with green, 3-veined center, often brown tinged, ovate, subequal to, not concealing perigynia, apex obtuse to acute.
    Perigynia appressed-ascending to loosely spreading at maturity, green or brown, often dark-brown in age, lightly several-veined, elliptic-ovate, 2–2.5 × 0.8–1.5 mm, widest near middle, membranous;
