Descriptions

Morphology General Habit
Perennial. Culms woody. Culm-internodes terete; thick-walled; striate; smooth. Culm-nodes glabrous. Lateral branches dendroid; spreading, or reflexed. Branch complement many; in a clump. Leaf-sheaths striately veined; puberulous. Leaf-sheath oral hairs ciliate. Ligule an eciliate membrane; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 2.5-5 cm long; 3-7 mm wide. Leaf-blade surface smooth; glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; without bracts, or bracteate at branch bases, or bracteate at pedicel base. Panicle open; lanceolate; nodding; bearing few spikelets. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 12.5 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 oblong; laterally compressed; 12.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume orbicular; 0.05-0.2 mm long; 0.5-0.6 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume oblong; 0.1-0.4 mm long; 0.05 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex truncate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret lanceolate; 6 mm long; 0.5 length of fertile lemma; chartaceous; 5 -veined; acute. Lemma of upper sterile floret elliptic; 6 mm long; chartaceous; acute. Fertile lemma oblong; 12.5 mm long; coriaceous; without keel. Lemma surface puberulous; hairy above. Lemma apex acute. Palea 4 -veined.
