Morphology General Habit
Annual. Culms erect; 50-80 cm long; 4 -noded. Culm-internodes distally glabrous, or pubescent. Leaf-sheaths striately veined; pilose; with reflexed hairs. Ligule an eciliate membrane; 2-3 mm long; pubescent on abaxial surface; lacerate; truncate. Leaf-blades 10-15 cm long; 4-8 mm wide. Leaf-blade surface pubescent; sparsely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; nodding; 10-15 cm long. Primary panicle branches spreading, or drooping; 2 -nate; 2-6 cm long; bearing 1-2 fertile spikelets on each lower branch. Panicle axis scabrous. Panicle branches flexuous; scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; scaberulous.
Fertile
Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed strongly; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; scaberulous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 10 mm long; 0.75 length of upper glume; membranous; much thinner on margins; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume apex acuminate. Upper glume lanceolate; 14 mm long; 0.9 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 5-7 -veined. Upper glume primary vein scabrous. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 15 mm long; chartaceous; keeled; 7 -veined. Lemma midvein scabrous. Lemma surface smooth, or scaberulous. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; 12-18 mm long overall. Palea keels ciliolate. Palea apex with excurrent keel veins. Apical sterile florets resembling fertile though underdeveloped.
