Morphology General Habit
Annual. Culms 20-70 cm long. Leaves mostly basal. Ligule a fringe of hairs. Leaf-blades 5-12 cm long; 1-4 mm wide. Leaf-blade apex attenuate; filiform.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; interrupted; 5-15 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear; bearing a few hairs.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 2-3 mm long; breaking up at maturity; disarticulating above glumes but not between florets.
Fertile
Spikelets comprising 1-2 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 2-3 mm long; breaking up at maturity; disarticulating above glumes but not between florets.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes deciduous; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume lanceolate; 1 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 1.5 mm long; 0.75 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; 2 mm long; membranous; keeled; 3 -veined. Lemma apex emarginate; awned; 1 -awned. Principal lemma awn 2 mm long overall. Palea 0.66 length of lemma; 2 -veined. Palea keels scabrous. Apical sterile florets 2-5 in number; barren; separate; linear; 0.5-1.5 mm long. Apical sterile lemmas awned; 1 -awned. Apical sterile lemma awns 3-8 mm long.
Morphology Reproductive morphology Flowers
Anthers 3; 0.1 mm long.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; ellipsoid.
Distribution
Asia-tropical: Malesia and Papuasia. Australasia: Australia.
