Morphology General Habit
Perennial. Stolons present. Culms decumbent; 200-300 cm long; 5-7 mm diam.; rooting from lower nodes. Culm-internodes solid; distally glabrous. Culm-nodes swollen. Lateral branches lacking, or sparse. Leaf-sheaths glabrous on surface, or pilose; outer margin hairy. Leaf-sheath oral hairs ciliate; 3-4 mm long. Ligule an eciliate membrane; 0.3-0.7 mm long; brown. Leaf-blades 20-70 cm long; 10-20 mm wide. Leaf-blade midrib keeled beneath. Leaf-blade surface glabrous, or pilose; sparsely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Peduncle 3-6 cm long. Racemes 8-33; borne along a central axis; unilateral; 7-16 cm long. Central inflorescence axis 5-11 cm long. Rhachis narrowly winged; 0.8-1.4 mm wide. Spikelet packing abaxial; 2 -rowed. Raceme-bases brief; pilose. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed strongly; acuminate; 3.7-4.6 mm long; falling entire.
Fertile
