Leaf-sheaths smooth; glabrous on surface. Ligule an eciliate membrane; 1.5-4.5 mm long; acute, or acuminate. Leaf-blades filiform; involute; 4-8 cm long; 0.6 mm wide. Leaf-blade surface smooth; glabrous. Leaf-blade apex abruptly acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle smooth, or scaberulous above. Panicle open; lanceolate; 3-5.5 cm long; 0.5-1.4 cm wide. Primary panicle branches appressed, or ascending; 1-3 -nate; 1-2.6 cm long; bearing 2-8 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets ovate; laterally compressed; 2.25-2.75 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.2-0.35 mm long; smooth. Floret callus glabrous.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets ovate; laterally compressed; 2.25-2.75 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.2-0.35 mm long; smooth. Floret callus glabrous.

Lower glume lateral veins absent. Lower glume surface asperulous. Lower glume apex acute. Upper glume lanceolate; 1.75-2.5 mm long; 0.75 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume surface asperulous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 2-2.4 mm long; membranous; keeled; 5 -veined. Lemma surface scaberulous. Lemma apex acute. Palea keels scaberulous. Rhachilla extension 0.4-0.65 mm long.
