Morphology General Habit
Perennial. Rhizomes short. Culms geniculately ascending; 40-50 cm long; rooting from lower nodes. Ligule an eciliate membrane. Leaf-blades 10-20 cm long; 3-9 mm wide; flaccid. Leaf-blade surface smooth. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; 4-7 cm long; 1 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 3.5-4 mm long; breaking up at maturity; disarticulating below each fertile floret.
