Leaf-sheaths longer than adjacent culm internode; striately veined; glabrous on surface. Ligule an eciliate membrane; 1 mm long; brown. Leaf-blades involute; 10-20 cm long; 2-4 mm wide; stiff. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 3-9 fertile spikelets. Panicle open; lanceolate; 8-10 cm long; bearing few spikelets. Primary panicle branches 1-2 -nate; indistinct the panicle almost racemose; 1-4 cm long; bearing 1 fertile spikelets on each lower branch. Panicle axis 2-3 noded; with lower internodes 1-3 cm long; scabrous. Panicle branches capillary; scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-10 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or elliptic; laterally compressed; compressed slightly; 15-20 mm long; 5-7 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 6-10 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or elliptic; laterally compressed; compressed slightly; 15-20 mm long; 5-7 mm wide; breaking up at maturity; disarticulating below each fertile floret.

Lemma margins ciliate. Lemma apex acute; awned; 1 -awned. Principal lemma awn apical; 3-7 mm long overall. Palea 10 mm long. Palea keels ciliate. Apical sterile florets resembling fertile though underdeveloped.
