Plants caespitose; innovation buds intravaginal. Culms 30–70 cm high. Inflorescences linearlanceolate. Spikelets 14.5–20 mm long, with 3–5 florets. Glumes much more than twice as long as florets; lower glume 14.5–20 mm long, 1.3–3 mm wide. Lemma: body 2–2.6 mm long, villous between the rows of tufts; both rows of hair tufts complete, with lower row not reaching upper row; lobes longer than body, up to more than twice as long; setae 1.8–5 mm long, shorter than or as long as lobes; awn 10.5–16.5 mm long, exceeding setae; awn column tightly twisted, equalling or exceeding lobes but shorter than setae. Palea linear, 3.3–5 mm long, 5–8 times as long as wide, much exceeding lemma sinus. Anthers 0.5–1.3 mm long. Caryopsis 1.7–2.1 mm long.
