Morphology General Habit
Annual. Culms erect; 15-50 cm long. Leaf-sheaths pilose. Ligule an eciliate membrane. Leaf-blades 8-20 cm long; 2-6 mm wide. Leaf-blade surface pubescent.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle pubescent above. Panicle open; elliptic; dense; equilateral; 15-20 cm long; 5-12 cm wide. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 20-30 mm long; 5-8 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pungent; disarticulating obliquely.
Fertile
Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 20-30 mm long; 5-8 mm wide; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pungent; disarticulating obliquely.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume linear; 15-18 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface glabrous, or hirsute. Lower glume apex acute. Upper glume lanceolate; 20-25 mm long; 0.9-1 length of adjacent fertile lemma; membranous; without keels; 3 -veined.
