Leaf-blade to 15 cm × 1–2.5 mm, flat, tapered; margins minutely scabrid towards tip, occasionally both, or only adaxial, surface with short hairs, adaxially ribs scabrid. Culm 25–70 cm, internodes entirely glabrous, or slightly and minutely scabrid below purplish nodes. Panicle 10–30 cm, lax; branches few, slender, in ± distant whorls, naked below; rachis, branchlets and pedicels short-scabrid, visible between spikelets. Spikelets purple, few. Glumes elliptic-lanceolate, acute; lower (2.5)–3–3.5–(4.5) mm, < lemma, upper (3.5)–4–5–(5.5) mm, ≤ or rarely > lemma. Lemma 4–6 mm, minutely scabrid, tip shortly bifid; awn 13.5–18.5 mm, purple, inserted c. 0.5 mm below lemma tip, column ± straight, awn twisting 2–3 times.
