erect, not stiff, 15–90 cm.

8.8–28 cm.

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.

blades mostly basal, dark green, equaling or mostly exceeding culms, 1.4–4 mm wide, thick, margins smooth or scabrous.

2–15 cm × 5–10 mm;

proximal bracts shorter than to exceeding spikes;

distal bracts usually scalelike.

peduncles of basal pistillate spikes filiform, arching, to 13 cm;

peduncles of terminal staminate spikes 2–6 cm;

proximal bracts short-sheathing;

pistillate spikes 2–5, mostly emerging from basal nodes, proximal spikes arching, distal ones ascending, short-pedunclulate, widely separated, often with 1–2 staminate flowers at apex, obovoid to ellipsoid;

terminal staminate spikes usually with 2–5 pistillate flowers at base, 7.5–9.8 × 1.8–2.3 mm.

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.
