Descriptions

Morphology General Habit
Perennial. Rhizomes elongated; leptomorph. Culms arching, or scandent; pendulous at the tip; 400-800 cm long; 10-20 mm diam.; woody; with root thorns from the nodes. Culm-internodes terete; solid; 20-38 cm long. Lateral branches dendroid. Branch complement many; in a clump; with subequal branches; thinner than stem. Culm-sheaths persistent. Leaves 5-6 per branch. Leaf-sheaths glabrous on surface; outer margin hairy. Ligule an eciliate membrane; 0.5 mm long. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 10-15 cm long; 8-17 mm wide. Leaf-blade apex attenuate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; embraced at base by subtending leaf. Panicle spiciform; linear; 5-12 cm long. Panicle axis angular; glabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 6-8 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 elliptic; laterally compressed; 6-8 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 ovate; 1.8-2.8 mm long; membranous; without keels. Lower glume apex acute. Upper glume ovate; 4-5.1 mm long; 0.5 length of adjacent fertile lemma; membranous; without keels. Upper glume apex obtuse.
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 mm long; 0.5 length of fertile lemma; chartaceous; 3 -veined; acute; mucronate. Lemma of upper sterile floret ovate; 4 mm long; chartaceous; acute; mucronate. Fertile lemma elliptic; 6-8 mm long; coriaceous; without keel; 7 -veined. Lemma lateral veins prominent. Lemma margins eciliate. Lemma apex acute.
