Morphology General Habit
Perennial. Stolons absent, or present. Basal innovations flabellate. Culms erect, or geniculately ascending; 30-75 cm long. Leaf-sheaths glabrous on surface, or pilose. Ligule a ciliate membrane. Leaf-blades conduplicate; 10-20 cm long; 1.5-3 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Peduncle glabrous. Racemes 5-9; digitate; erect, or ascending; unilateral; 4-8 cm long. Rhachis subterete; pilose on surface. Spikelet packing broadside to rhachis; regular. Spikelets solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 2.3-3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.
Fertile
Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 2.3-3 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus bearded; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
