Descriptions

Morphology General Habit
Perennial. Culms 150 cm long; 2 mm diam.; woody. Culm-internodes terete; 6-8.5 cm long; smooth; distally glabrous. Lateral branches dendroid; intravaginal. Branch complement one. Culm-sheaths persistent. Leaves 4-5 per branch. Leaf-sheaths without keel; striately veined; glabrous on surface; outer margin glabrous. Leaf-sheath oral hairs pubescent. Ligule an eciliate membrane; 0.3-0.4 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.15 cm long. Leaf-blades lanceolate; 20-26 cm long; 5-6 mm wide. Leaf-blade venation without cross veins, or with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; linear; interrupted; 12.5-15 cm long; 0.5-0.8 cm wide. Primary panicle branches 1.2-1.5 cm long. Panicle axis angular; pubescent. Panicle branches pubescent. Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels 0.5-2 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; compressed slightly; 6.5-7.2 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; compressed slightly; 6.5-7.2 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume oblate; 0.6-1.3 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume surface glabrous. Lower glume apex obtuse. Upper glume ovate; 1-2 mm long; membranous; without keels; 0-1 -veined. Upper glume primary vein absent, or distinct. Upper glume lateral veins absent. Upper glume surface glabrous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 3.1-3.7 mm long; chartaceous; 5 -veined; puberulous; hairy above; acute; awned. Awn of lower sterile floret 1.7-2.4 mm long. Lemma of upper sterile floret ovate; 3.8-4.1 mm long; chartaceous; pubescent; acute; awned. Awn of upper sterile floret 1.5-2.7 mm long. Fertile lemma ovate; 5.3-5.4 mm long; coriaceous; without keel; 7 -veined. Lemma surface puberulous; hairy above. Lemma apex awned; 1 -awned. Principal lemma awn 1-1.6 mm long overall. Palea 4.8-5 mm long; 4 -veined. Palea surface puberulous.
