Morphology General Habit
Perennial; caespitose. Culms erect, or geniculately ascending; robust; 30-200(-300) cm long. Leaf-sheaths keeled; glabrous on surface, or pilose. Ligule a fringe of hairs; 1-1.6 mm long. Leaf-blades 5-56 cm long; 1-19 mm wide. Leaf-blade venation distinct. Leaf-blade surface scabrous; glabrous, or pilose; sparsely hairy; hairy on both sides. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle hirsute above. Panicle spiciform; linear; loose (internodes 1-3.2mm); 4-23.5 cm long; 1-2.8 cm wide. Primary panicle branches accrescent to a central axis; with sessile scars on axis. Panicle axis angular, or with briefly decurrent ribs; pubescent; 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, or ovate, or globose; 4-10.8 mm long; base bluntly stipitate; base 0.3-3 mm long; base pubescent. Involucral bristles deciduous with the fertile spikelets; numerous; with an outer whorl of thinner bristles; 8-12 in principal whorl; inner bristles longer than outer; with longest bristle scarcely emergent, or with one conspicuously longer bristle; 4-10 mm long; terete; without grooves; rigid; retrorsely scaberulous; pubescent, or ciliate; spinose.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; acuminate; 3.8-6.5 mm long; falling entire; deciduous with accessory branch structures.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or ovate; dorsally compressed; acuminate; 3.8-6.5 mm long; falling entire; deciduous with accessory branch structures.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.2-3.5 mm long; 0.3-0.5 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong, or ovate; 2.4-4.8 mm long; 0.6-0.75 length of spikelet; membranous; without keels; 3-5 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male, or barren; with palea, or without significant palea. Lemma of lower sterile floret oblong, or ovate; 3.5-6.5 mm long; 1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma ovate; 3.8-6.1 mm long; cartilaginous, or coriaceous; much thinner on margins; without keel; 3 -veined. Lemma margins flat. Lemma apex obtuse, or acute. Palea 1 length of lemma; cartilaginous, or coriaceous.
