Morphology General Habit
Annual. Culms erect, or geniculately ascending; 30-60 cm long. Culm-internodes distally glabrous, or pubescent. Leaf-sheaths pubescent. Ligule an eciliate membrane. Leaf-blades 10-20 cm long; 2-5 mm wide. Leaf-blade surface pubescent.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 5-20 cm long; 2-15 cm wide. Primary panicle branches spreading; whorled at most nodes; bearing 1-4 fertile spikelets on each lower branch. Panicle branches flexuous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-14 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; (15-)30-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 6-14 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; (15-)30-50 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 9-11 mm long; 1 length of upper glume; membranous; without keels; 3(-5) -veined. Lower glume surface glabrous, or hispidulous. Lower glume apex acuminate. Upper glume lanceolate, or ovate; 9-13 mm long; 0.75 length of adjacent fertile lemma; membranous; without keels; 5-7 -veined. Upper glume surface glabrous, or hispidulous. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 12-18 mm long; herbaceous; much thinner on margins; purple; without keel; 7 -veined. Lemma surface glabrous, or hispidulous. Lemma apex dentate; 2 -fid; with lobes 1.2-2.5 mm long; awned; 1 -awned. Principal lemma awn subapical; reflexed and briefly coiled at base of limb; flat below; 15-30 mm long overall. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
