Descriptions

Morphology General Habit
Perennial. Culms arching, or scandent; 300-1000 cm long; 10-25 mm diam.; woody; with root thorns from the nodes. Culm-internodes terete; solid; 10.5-27.5 cm long; yellow, or brown; smooth. Lateral branches dendroid; infravaginal. Bud complement 100. Branch complement many; girdling the culm; with subequal branches; thinner than stem. Culm-sheaths deciduous; 9.2-21.5 cm long; antrorsely scabrous. Culm-sheath ligule 0.5 mm high. Culm-sheath blade triangular; indistinctly demarcated from sheath; erect; 2.5-9 cm long; scabrid. Leaves 4-9 per branch. Ligule an eciliate membrane; 0.5-1 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.3 cm long; petiole pubescent. Leaf-blades lanceolate; 2.7-8.5 cm long; 4-15 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; comprising 19-26 fertile spikelets. Panicle open; ovate; 10-15 cm long. Primary panicle branches spreading; 2-4 cm long. Panicle axis angular; glabrous. Panicle branches angular; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-10 mm long; glabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 7.2-9 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; 7.2-9 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; 0.6-1 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.8-1.4 mm long; membranous; without keels; 0-1 -veined. Upper glume primary vein absent, or obscure. Upper glume lateral veins absent. Upper glume apex obtuse, or 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; 2.4-3.1 mm long; 0.25-0.33 length of fertile lemma; chartaceous; 1-3 -veined; without lateral veins, or distinctly veined; acute. Lemma of upper sterile floret ovate; 3.4-4 mm long; chartaceous; acute. Fertile lemma ovate; 7.5-8 mm long; coriaceous; without keel; 9-11 -veined. Lemma lateral veins prominent. Lemma apex apiculate. Palea 7.3-8 mm long; 4 -veined. Palea keels contiguous above a sulcus.
