blades yellow-green or bright green, involute-cylindric, quill-shaped, 6–25 cm, 0.3–0.7 mm wide near base.

sheaths usually loose, proximal green-and-white-striped and green-and-white-mottled, with conspicous transverse veins on back, fronts white to hyaline, sometimes red dotted and transversely rugose, yellow or brown and thickened at mouth;

ligules 1–4.5 mm, shorter than to as long as wide;

widest leaf blades 3.5–5 mm wide.

with 5–10 spikes, (1.5–)2–5 cm × 8–13 mm;

proximal internodes shorter than to as long as proximal spikes;

proximal bracts to 3 cm;

spikes with 5–15 ascending to spreading perigynia.

7–30 × 3–7 mm, staminate portion 4–14 mm.
