Descriptions

Morphology General Habit
Perennial. Culms erect; 4 mm diam.; woody; without nodal roots. Culm-internodes terete; thick-walled; 3-3.5 cm long; distally pruinose. Culm-nodes flush with internodes; without obvious supra-nodal ridge. Lateral branches dendroid; intravaginal; erect. Bud complement 1, or 3. Branch complement one, or three; solitary, or in a horizontal line. Culm-sheaths persistent; without auricles. Leaves 6-7 per branch. Leaf-sheaths tight; glabrous on surface; outer margin hairy. Ligule an eciliate membrane; 1 mm long; pubescent on abaxial surface; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1 cm long. Leaf-blades lanceolate; 7.3-10.8 cm long; 8-11 mm wide; coriaceous. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; embraced at base by subtending leaf. Panicle contracted; linear; 3-4 cm long. Primary panicle branches appressed. Panicle axis scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2-3 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 5.2-5.8 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 ovate; laterally compressed; 5.2-5.8 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; 0.3-0.5 mm long; 0.66 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume orbicular; 0.5 mm long; 0.1-0.15 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse.
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 ovate; 2.5-3.8 mm long; 0.5-0.66 length of fertile lemma; chartaceous; 3 -veined; acute. Lemma of upper sterile floret ovate; 3.4-3.8 mm long; 1.3 length of lower sterile floret; chartaceous; acute; mucronate. Fertile lemma ovate; 5.2-5.8 mm long; coriaceous; without keel. Lemma apex acute; mucronate. Palea 1 length of lemma.
