erect, not stiff, 15–90 cm.

30–80 cm, distally scabrous.

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.

basal and cauline, 4–8 mm wide;

proximal leaves reduced to sheaths.

2–15 cm × 5–10 mm;

proximal bracts shorter than to exceeding spikes;

distal bracts usually scalelike.

proximal bracts usually exceeding, occasionally shorter than, inflorescences;

spikes separate, the proximal often distant, pendent, long-pendunculate, elongate, cylindric or clavate, 10–40 × 7–9 mm;

lateral 4–6(–9) spikes pistillate;

terminal spike gynecandrous.

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.

appressed-ascending, gray-green, becoming yellowish brown, obscurely many-veined, elliptic-ovate, 1.8–3 × 1.2–1.7 mm, widest near middle, membranous;

beak abaxial suture inconspicuous, small marginal teeth.

ascending, green becoming pale yellow or brown, faintly veined, ovate, 4–5 × 2.5–3.5 mm, apex gradually beaked, smooth;

beak 0.3–0.4 mm, truncate or obscurely bidendate, smooth.

pale brown, oblong-obovate, 1.25–1.5 × 1–1.25 mm, dull to slightly glossy.

filling proximal 1/2 or less of perigynia.

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.

scales dark brown or black to margins, ovate or lanceolate, conspicuously shorter and narrower than perigynia, midvein lighter colored than body, conspicuous, often raised, prominent, mucronate.
