Descriptions

Morphology General Habit
Annual; caespitose. Culms geniculately ascending, or decumbent; 10-45 cm long. Leaf-sheath oral hairs lacking. Ligule a fringe of hairs. Leaf-blades 1-7 cm long; 1-2 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 3-8 cm long. Primary panicle branches spreading; 1 -nate. Panicle branches stiff. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 8-25 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4-10 mm long; 1.2 mm wide; breaking up at maturity; rhachilla persistent; retaining paleas.
