Morphology General Habit
Perennial; caespitose; clumped loosely. Culms 20-40 cm long; 3-4 -noded. Leaf-sheaths 2-10 cm long; glabrous on surface. Ligule an eciliate membrane; 1 mm long. Leaf-blades 7-15 cm long; 3-6 mm wide. Leaf-blade venation comprising 15 vascular bundles. Leaf-blade surface smooth, or scaberulous; rough on both sides; glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; 8-16 cm long. Primary panicle branches 1-2 -nate. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-5 mm long; puberulous to villous; hairy above.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma; shiny. Lower glume obovate; 1 length of upper glume; membranous; much thinner on margins; 1-keeled; 3 -veined. Lower glume apex obtuse, or acute. Upper glume obovate; 6 mm long; 1 length of spikelet; membranous; with scarious margins; 1-keeled; 3 -veined. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets dissimilar; male; with palea; attached to and deciduous with the fertile. Lemma of lower sterile floret oblong; 5.5 mm long; chartaceous; light brown; 1-keeled; scaberulous; ciliate on margins; obtuse; awned. Awn of lower sterile floret dorsal; arising 0.75 way up back of lemma; straight; 2-3 mm long. Lemma of upper sterile floret oblong; 1 length of lower sterile floret; chartaceous; scabrous; ciliate on margins; obtuse; awned. Awn of upper sterile floret dorsal; arising 0.75 way up back of lemma; geniculate; 4-6 mm long. Fertile lemma ovate; 4 mm long; cartilaginous; without keel. Lemma surface pubescent; hairy above. Lemma margins convolute; covering most of palea. Lemma apex mucronate, or awned. Principal lemma awn subapical; 1-2 mm long overall. Palea elliptic; without keels.
Morphology Reproductive morphology Flowers
Anthers 2 (bisexual), or 3 (male); 2 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp.
Distribution
Australasia: New Zealand.
