Morphology General Habit
Annual. Culms erect, or geniculately ascending; 50-80 cm long. Ligule a fringe of hairs. Leaf-blades 10-25 cm long; 5-12 mm wide. Leaf-blade surface smooth to scabrous; glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes borne along a central axis; unilateral; 2-4 cm long. Central inflorescence axis 7-15 cm long; with scattered hairs, or glabrous. Rhachis angular; with scattered hairs, or glabrous on surface. Spikelet packing regular; 2 -rowed. Spikelets solitary, or in pairs. Fertile spikelets pedicelled. Pedicels oblong; scabrous; bearing a few hairs, or glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; (5-)5.5-7 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; (5-)5.5-7 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes one the lower absent or obscure; exceeding apex of florets; thinner than fertile lemma. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume surface scabrous; rough above; pilose; hairy above. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-3 mm long.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; 5 -veined; scabrous; rough above; pilose; hairy below; acuminate. Fertile lemma elliptic; 2.5-3.5 mm long; indurate; without keel. Lemma margins involute. Lemma apex obtuse; mucronate. Palea involute; indurate.
