Morphology General Habit
Perennial; short-lived. Culms erect; slender; 30-75 cm long; 3-5 -noded. Culm-nodes glabrous. Lateral branches lacking, or sparse. Leaf-sheaths keeled; outer margin glabrous. Ligule a fringe of hairs. Leaf-blades lanceolate; 10-20 cm long; 3-5 mm wide. Leaf-blade surface scaberulous; glabrous, or pilose; with tubercle-based hairs. Leaf-blade margins cartilaginous; scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; pyramidal; effuse; 8-12 cm long. Primary panicle branches spreading; whorled at lower nodes. Panicle branches capillary. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 1-1.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 1-1.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes deciduous; reaching apex of florets. Lower glume ovate; 0.5-0.75 mm long; 0.5 length of upper glume; membranous; much thinner on margins; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume ovate; 1-1.5 mm long; 1 length of adjacent fertile lemma; membranous; with hyaline margins; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 1-1.5 mm long; membranous; keeled; 1 -veined. Lemma apex acute. Palea readily splitting down midline; 0.9 length of lemma; 2 -veined. Palea keels approximate.
Morphology Reproductive morphology Fruits
Caryopsis with free soft pericarp; obovoid; laterally compressed; quadrangular; 0.5 mm long; truncate.
Distribution
Australasia: Australia.
