Morphology General Habit
Perennial. Culms 100-150 cm long. Lateral branches lacking. Leaf-sheaths longer than adjacent culm internode; antrorsely scabrous; glabrous on surface, or pilose; with tubercle-based hairs. Ligule an eciliate membrane; 1 mm long; erose. Leaf-blades 12-30 cm long; 8-26 mm wide. Leaf-blade surface scabrous; pilose; sparsely hairy; hairy on both sides. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 15-25; borne along a central axis; drooping; unilateral; 3-15 cm long; simple, or secondarily branched. Central inflorescence axis 20-35 cm long. Rhachis angular. Raceme-bases filiform; 10-60 mm long. Spikelets ascending; solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume lanceolate; 3.5-4 mm long; 0.8-0.9 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume apex acute. Upper glume ovate; 4-5 mm long; 0.6-0.7 length of adjacent fertile lemma; membranous; 1-keeled; 3-5 -veined. Upper glume primary vein scabrous. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 6-7 mm long; membranous; keeled; 3 -veined. Lemma midvein ciliate. Lemma margins ciliate. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; 2-7 mm long overall. Palea 1 length of lemma. Palea keels ciliate. Apical sterile florets 1 in number; barren; lanceolate. Apical sterile lemmas awned.
