Morphology General Habit
Annual. Culms geniculately ascending; 40-80 cm long. Culm-nodes glabrous. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule a fringe of hairs; 0.5-1 mm long. Collar pilose. Leaf-blades linear, or lanceolate; 5-15 cm long; 4-10 mm wide. Leaf-blade surface scabrous; rough on both sides; pubescent; hairy on both sides. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle scaberulous above. Panicle spiciform; linear; dense; 3-10 cm long; 0.5 cm wide. Primary panicle branches sterile at the tips. Panicle axis angular; with scattered hairs and pubescent. Spikelets subtended by an involucre. Fertile spikelets pedicelled; 1 in the cluster. Involucre composed of bristles; 3-5 mm long. Involucral bristles persistent; 1-3 per spikelet; flexible; retrorsely scaberulous; retrorse above, antrorse below; glabrous. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed slightly; 1.5 mm long; falling entire.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; compressed slightly; 1.5 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; clasping; 0.5 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume ovate; 0.9 length of spikelet; membranous; mid-green; without keels; 5 -veined. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; with palea. Lemma of lower sterile floret ovate; 1 length of spikelet; membranous; mid-green; 5 -veined; acute. Palea of lower sterile floret 0.5 length of lemma. Fertile lemma ovate; dorsally compressed; gibbous; 1.5 mm long; indurate; without keel. Lemma surface rugulose. Lemma margins involute. Palea involute; indurate.
