Morphology General Habit
Annual; culms solitary, or caespitose. Culms erect, or geniculately ascending; 4-25 cm long. Leaf-sheaths pubescent. Ligule an eciliate membrane. Leaf-blades 2-10(-20) cm long; 2-3 mm wide. Leaf-blade surface pubescent.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; obovate; 2-6 cm long; 0.7-2 cm wide. Primary panicle branches bearing 1(-2) fertile spikelets on each lower branch. Panicle branches pubescent. Spikelets solitary. Fertile spikelets sessile, or pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets with diminished florets at the apex. Spikelets cuneate; laterally compressed; 10-20 mm long; 5-12 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets with diminished florets at the apex. Spikelets cuneate; laterally compressed; 10-20 mm long; 5-12 mm wide; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume linear; 6-8 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 8-12 mm long; 0.75-0.9 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile florets divergent. Fertile lemma lanceolate; 11-15 mm long; 1-1.5 mm wide; chartaceous; without keel; (3-)5 -veined. Lemma margins involute. Lemma apex dentate; 2 -fid; with lobes 0.5-1.5 mm long; awned; 1 -awned. Principal lemma awn subapical; curved; 10-18 mm long overall. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 0.4-0.5 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; linear; 7.5-13 mm long; hairy at apex; apex fleshy. Hilum linear.
