Lax, slender tufts 6.5–30–(60) cm, with delicate panicles equalling or overtopping the usually soft flaccid leaves; branching extravaginal. Leaf-sheath membranous, light green to light brown; lower sheaths often with minute retrorse prickle-teeth or hairs, upper sheaths glabrous. Ligule 0.8–2 mm, truncate to ± obtuse, slightly erose, abaxially finely scabrid. Leaf-blade 2–8 cm × 0.5–1.5–(3) mm, flat, or folded and inrolled at margins, abaxially smooth, or sometimes scabrid, especially towards tip and on uppermost culm-leaves, adaxially ciliate-scabrid on ribs; margins sparsely scabrid, occasionally almost smooth, tip acute, scabrid. Culm usually geniculate at base or erect, internodes glabrous. Panicle (2)–4.5–8.5–(16) cm, ovate-lanceolate to pyramidal with filiform branches naked below and spreading widely at maturity; rachis, branches and pedicels sparsely scabrid. Spikelets c. 2–2.5–(3) mm, purplish green.
