Morphology General Habit
Annual. Culms erect; 8-40 cm long; 1-4 -noded. Culm-nodes pubescent. Leaf-sheaths tubular for much of their length; pubescent. Ligule an eciliate membrane; 2-3 mm long; erose. Leaf-blades 2-15 cm long; 1-4 mm wide.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate, or oblong; 6-15 cm long. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.2-2.5 mm long; glabrous. Floret callus pubescent; hairy on the margins; obtuse.
Fertile
Spikelets comprising 2-5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.2-2.5 mm long; glabrous. Floret callus pubescent; hairy on the margins; obtuse.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume linear; 4.1-4.6 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume linear; 5.2-6 mm long; 0.66 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 8-10 mm long; chartaceous; without keel; 7 -veined. Lemma surface glabrous to pubescent. Lemma apex dentate; 2 -fid; with lobes 0.5-1 mm long; incised 0.1 of lemma length; awned; 1 -awned. Principal lemma awn subapical; geniculate; with twisted column. Palea lanceolate; 6-9 mm long; 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; 0.2-0.3 mm long. Anthers 3; 1 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
