Leaf-blades convolute; 12–24 cm long; 3–5 mm wide; stiff; glaucous. Leaf-blade surface scabrous; rough adaxially. Leaf-blade margins scabrous. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; linear, or elliptic; 4–8 cm long; 1–1.2 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs; pubescent.

Spikelets appressed; solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; compressed strongly; 5–6 mm long; falling entire. Spikelet callus base obtuse.

GLUMES Glumes similar; shorter than spikelet; thinner than fertile lemma; gaping. Lower glume lanceolate; 3.5–4 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein ciliolate. Lower glume lateral veins absent. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 2–4 mm long. Upper glume lanceolate; 3.5–4 mm long; 0.8–1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein ciliolate. Upper glume lateral veins absent. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 2–4 mm long.

FLORETS Fertile lemma lanceolate, or oblong; 4–5 mm long; membranous; much thinner above; keeled; 5 -veined. Lemma lateral veins with distinct primaries but obscure intermediates. Lemma margins eciliate, or pubescent; hairy below. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 0.5–1 mm long overall. Palea 1 length of lemma. Apical sterile florets 1–3 in number; male, or barren; separate; oblong. Apical sterile lemmas mucronate.
