Descriptions

Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms 400-500 cm long; 15-20 mm diam.; woody; without nodal roots. Culm-internodes terete; thin-walled; 20-35 cm long; smooth; distally pruinose. Lateral branches dendroid. Branch complement many. Culm-sheaths 20-30 cm long; 4 times as long as wide; chartaceous; yellow; pubescent; truncate at apex. Culm-sheath ligule brown. Culm-sheath blade linear; reflexed; 7-13 cm long. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs pubescent. Ligule an eciliate membrane; obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2 cm long. Leaf-blades linear, or oblong; 7-15 cm long; 12-20 mm wide; dark green. Leaf-blade midrib evident. Leaf-blade venation with 6-8 secondary veins; without cross veins. Leaf-blade surface smooth. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes; subtended by a spatheole; embraced at base by subtending leaf. Racemes 1; single; 2.5 cm long; bearing few fertile spikelets; bearing 5-7 fertile spikelets on each. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet. Lower glume oblong; chartaceous; without keels; 3-5 -veined. Lower glume apex acute; muticous, or mucronate. Upper glume oblong; 7-9 mm long; chartaceous; without keels; 3-5 -veined. Upper glume apex acute; muticous, or mucronate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 8-9 mm long; chartaceous; without keel; 5-7 -veined. Lemma margins ciliolate; hairy above. Lemma apex mucronate. Palea 1 length of lemma; 4 -veined. Palea apex pubescent; with excurrent keel veins. Rhachilla extension pilose; hairy at tip. Apical sterile florets distinct from fertile; 1 in number; rudimentary.
Morphology Reproductive morphology Flowers
Lodicules 3; veined; ciliate. Anthers 3; purple. Stigmas 3. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; oblong; sulcate on hilar side; apex unappendaged.
