Morphology General Habit
Perennial; caespitose. Butt sheaths herbaceous; pallid. Basal innovations intravaginal. Culms slender; 15-60 cm long; 1-2 -noded. Culm-internodes terete; smooth. Culm-nodes glabrous. Lateral branches lacking. Leaf-sheaths smooth, or scaberulous; glabrous on surface. Ligule a ciliolate membrane; 0.5-1.5 mm long; glabrous on abaxial surface, or scaberulous on abaxial surface; truncate. Leaf-blades filiform; involute; 3-15 cm long; 0.2-0.4 mm wide. Leaf-blade surface scaberulous; glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Peduncle smooth. Panicle open; elliptic; effuse; 2-12 cm long. Primary panicle branches 2-5 -nate; sparsely divided. Panicle branches capillary; scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scaberulous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth. Floret callus glabrous.
Fertile
Spikelets comprising 2-7 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 4-8 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth. Floret callus glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 0.9 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume surface smooth, or asperulous; rough above. Lower glume apex acute. Upper glume lanceolate; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume surface smooth, or asperulous; rough above. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong; lanceolate in profile; 3-4 mm long; membranous; keeled; 5 -veined. Lemma midvein without distinctive roughness, or scaberulous; eciliate, or ciliolate; hairy below. Lemma margins eciliate, or ciliolate; hairy at base. Lemma apex acute. Palea 0.9 length of lemma. Palea keels scabrous; adorned above. Palea surface smooth, or scabrous. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3; 1.5-2.5 mm long; yellow, or purple.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
Distribution
Australasia: Australia.
