Leaf-blade 2-13 cm × 0.2-0.4 mm diam., involute, filiform, flaccid, abaxially finely striate and, in young leaves, finely scabrid, later smooth, adaxially scabrid on ribs; margins scabrid, tip fine, blunt. Culm almost filiform, erect or geniculate at base, internodes glabrous. Panicle (2.5)-5-9 cm × 2-3 mm, contracted, extremely narrow-linear; rachis and few short erect branches and pedicels sparsely, finely scabrid, often pale purplish. Spikelets 1.5-2.4 mm, pale greenish purple to straw coloured. Glumes ± equal, lanceolate, minutely scabrid on keel and on margins near acute tip. Lemma 1.5-1.9 mm, at times ≈ glumes, glabrous, faintly 5-nerved, ovate-oblong, apex denticulate, awnless, or rarely a few lemmas subapically awned, awn straight, fine, up to 1 mm, scarcely projecting beyond glumes.
