Descriptions

Morphology General Habit
Annual. Culms 80-140 cm long. Culm-internodes terete. Ligule a fringe of hairs. Leaf-blades 10-55 cm long; 4-10 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 3-6; borne along a central axis; unilateral; 1.5-3 cm long. Rhachis angular; pilose on surface; ciliate on margins. Spikelet packing crowded. Spikelets pectinate; solitary. Fertile spikelets pedicelled. Pedicels oblong; villous; tip discoid.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 4-5 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; 4-5 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; herbaceous; without keels. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 1-1.5 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; membranous; acuminate. Fertile lemma elliptic; 3.5-4.5 mm long; indurate; without keel. Lemma surface granulose. Lemma margins involute. Lemma apex obtuse; pubescent; muticous. Palea involute; indurate.
