Morphology General Habit
Annual; caespitose. Culms erect; 30-200 cm long. Leaf-sheaths glabrous on surface. Ligule a fringe of hairs. Leaf-blades 10-30 cm long; 4-10 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes borne along a central axis; closely spaced (inflorescence lanceolate); unilateral; 1-4 cm long; simple. Central inflorescence axis 8-25 cm long. Rhachis angular. Spikelet packing crowded; regular; 4 -rowed. Spikelets in pairs. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; gibbous; acute; 1.5-2.5(-3) mm long; falling entire.
Fertile

Lower glume surface pubescent, or hispid. Lower glume apex acute. Upper glume ovate; membranous; purple; without keels; 5 -veined. Upper glume surface pubescent, or hispidulous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
