Morphology General Habit
Perennial. Culms robust; 60-150 cm long. Leaf-sheaths pubescent. Ligule a fringe of hairs; 1-2 mm long. Leaf-blades 14-34 cm long; 3.3-10.2 mm wide. Leaf-blade surface pilose; sparsely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; dense (internodes 1.2-2.8mm); 10.5-16 cm long; 1.1-1.5 cm wide. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1-3 in the cluster. Involucre composed of bristles; connate into a disc below; with 0.5 mm connate; oblong; 9.8-14 mm long; base truncate (0.5-0.8mm); base glabrous. Involucral bristles deciduous with the fertile spikelets; with an outer whorl of thinner bristles; 5-15 in principal whorl; inner bristles longer than outer; with one conspicuously longer bristle; 6.2-11.4(-25) mm long; expanded (narrowly elliptic, 0.5mm wide); flexible; antrorsely scaberulous; glabrous, or ciliate; attenuate.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 5-7.5 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 5-7.5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 1-1.5 mm long; 0.2-0.3 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 5-7.4 mm long; 1 length of spikelet; membranous; without keels; 3-5 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 5.5-7 mm long; 1 length of spikelet; membranous; 3-5 -veined; acute. Fertile lemma ovate; 4.9-6.1 mm long; coriaceous; much thinner on margins; without keel; 3 -veined. Lemma margins flat. Lemma apex obtuse. Palea coriaceous.
