Morphology General Habit
Perennial. Culms geniculately ascending; 20-40 cm long. Lateral branches lacking. Leaf-sheaths longer than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane; 7-8 mm long; pubescent on abaxial surface; lacerate. Leaf-blades 6-8 cm long; 2.5-3 mm wide. Leaf-blade surface scaberulous. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate; 13 cm long; 3 cm wide. Primary panicle branches ascending, or spreading; bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets. Spikelets elliptic; laterally compressed; 3-3.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets. Spikelets elliptic; laterally compressed; 3-3.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
