Stout or slender, moderately tall, extravaginal tufts, leaves < culms. Leaf-sheath light brown, sometimes purplish, usually glabrous below and scaberulous above, rarely with projecting hairs. Ligule (0.5)-1-1.5 mm, membranous, truncate, ciliate, abaxially scabrid to ciliate, often asymmetric. Leaf-blade to 10 cm × 1.5-2.5 mm, rather stiff, flat, minutely scabrid on ribs and margins, tapered towards tip. Culm 35-70 cm, internodes glabrous, often minutely scaberulous near nodes. Panicle (5.5)-10-16 cm, ± lax, with short, ± erect, few-flowered branches; rachis, branchlets and pedicels short-scabrid, partly hidden among spikelets. Spikelets pale, shining. Glumes ± equal, > lemma, elliptic-lanceolate, aristate; lower 4-5.5-(6) mm, upper 4.5-6 mm. Lemma 3.5-5 mm, surface minutely scabrid, tip opaque, scabrid, bifid; awn 10-20 mm, once-geniculate, brownish, inserted 0.3-0.5-(0.9) mm below lemma tip, column tightly twisted several times. Palea 3-4 mm, narrow-linear, keels scabrid near ciliate tip. Callus hairs 0.5-1 mm. Rachilla prolongation usually obvious, up to c. 1 mm. Lodicules 0.5-0.7 mm, elliptic-oblong, bifid at shortly ciliate tip. Anthers 1-3, 0.8-1.9 mm in chasmogamous flowers, 0.4-0.9 mm in cleistogamous flowers. Caryopsis (1.4)-1.8-2 × 0.3-0.4 mm; embryo 0.2-0.4 mm; hilum (1.2)-1.6-1.8 mm.
