Morphology General Habit
Perennial; caespitose; clumped loosely. Culms erect; 40-45 cm long. Culm-internodes smooth. Ligule an eciliate membrane; 3 mm long; lacerate. Leaf-blades flat, or convolute; 0.6-2.2 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 6-16 cm long; 5 cm wide. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 3 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 3 mm long; breaking up at maturity; disarticulating below each fertile floret.
