Morphology General Habit
Perennial. Rhizomes elongated. Culms erect; 50-150 cm long; swollen at the base; forming an ovoid corm. Leaf-sheaths ribbed. Ligule an eciliate membrane; 5-8 mm long; acute. Leaf-blades 10-30 cm long; 4-10 mm wide. Leaf-blade surface scabrous; rough adaxially.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 4-15; borne along a central axis; ascending, or erect; unilateral; 1-3 cm long. Central inflorescence axis 18-25 cm long. Rhachis angular. Spikelet packing crowded; regular; 2 -rowed. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong; 0.2 mm long; tip cupuliform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets obovate, or orbicular; laterally compressed; 2.5-3.7 mm long; falling entire. Rhachilla internodes suppressed between florets. Floret callus pubescent.
Fertile
