Descriptions

Morphology General Habit
Perennial; culms solitary. Rhizomes elongated; pachymorph. Culms scandent; 1000-2500 cm long; 5-10 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; smooth, or antrorsely scabrous. Lateral branches dendroid; extravaginal. Branch complement many; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths purple; glabrous; without auricles. Culm-sheath blade linear; 2 cm long. Leaves 3-5 per branch. Leaf-sheaths glabrous on surface, or puberulous; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule an eciliate membrane; 0.5-1 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1 cm long. Leaf-blades deciduous at the ligule; lanceolate; 5.5-9 cm long; 8-14 mm wide. Leaf-blade venation comprising 6 vascular bundles (primary). Leaf-blade surface glabrous, or pubescent; sparsely hairy.
Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes bearing few fertile spikelets; 2-4 fertile spikelets on each. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-4.5 mm long.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 7.7-10.5 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 ovate; laterally compressed; 7.7-10.5 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 ovate; 0.2 mm long; 0.5 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.3-0.5 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 acute.
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; 4.6-5 mm long; chartaceous; 1-3 -veined; without lateral veins, or obscurely veined; glabrous, or puberulous; hairy at base; acute. Lemma of upper sterile floret ovate; 4.9-6.2 mm long; chartaceous; glabrous, or pubescent (at base); acute. Fertile lemma ovate; 8-9.7 mm long; coriaceous; without keel; 5-7 -veined. Lemma apex acute. Palea 5-10 mm long; 5 -veined. Palea keels approximate. Palea apex dentate; 2 -fid.
