Morphology General Habit
Annual. Culms geniculately ascending, or decumbent; 25-80 cm long. Leaf-sheaths glabrous on surface. Ligule a fringe of hairs. Leaf-blades 7-20 cm long; 3-6 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 3-8; borne along a central axis; in several whorls, or distant (inflorescence linear); ascending, or erect; unilateral; 1-3 cm long; simple. Central inflorescence axis 5-20 cm long. Rhachis angular. Spikelet packing 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; cuspidate; 2.3-3 mm long; falling entire.
Fertile

Lower glume apex cuspidate. Upper glume ovate; membranous; without keels; 5 -veined. Upper glume surface pubescent. Upper glume apex cuspidate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 5 -veined; pubescent; cuspidate; muticous, or awned. Awn of lower sterile floret 0-6 mm long. Fertile lemma ovate; gibbous; 2.3-2.5 mm long; indurate; much thinner above; shiny; without keel; 5 -veined. Lemma margins involute.
