3–22 cm, strongly scabrous distally;

bases (remnants of old leaves) fibrous.

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.

terminal spike staminate for less than 1/2 of length, often clavate due to more conspicuous staminate part.
