Leaf-sheath pale green, later creamy brown, shining, ± membranous, smooth, or very minutely scabrid throughout, ribs inconspicuous.

Leaf-blade (10)–20–60 cm ×c. 1–1.5–(2.5) mm, folded or ± flat, coriaceous, abaxially glabrous, midrib and lateral ribs not very prominent, adaxially closely minutely pubescent throughout; margins inrolled, scabrid, midnerve scabrid near acicular, often pungent tip. Culm (10)–20–50–(70) cm, ≤ leaves, internodes smooth to scabrid below panicle. Panicle (5)–10–20–(25) cm, open; branches slender, ± erect to spreading, sparsely to very closely scabrid, naked below, spikelets many on shorter secondary branchlets.
