Morphology General Habit
Perennial. Culms scandent; 1000-1500 cm long; 10-15 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; 27-50 cm long; mid-green, or purple; smooth, or retrorsely scabrous. Lateral branches dendroid; extravaginal. Bud complement 100. Branch complement many; in a clump; thinner than stem. Culm-sheaths deciduous; 11-22 cm long; glabrous, or hispid. Culm-sheath ligule 3-4 mm high; ciliate. Culm-sheath blade triangular; deciduous; reflexed; 2.7-6 cm long; glabrous on surface. Leaves 4-6 per branch. Ligule an eciliate membrane; 2 mm long; truncate, or obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2-0.4 cm long; petiole pubescent. Leaf-blades lanceolate; 5.6-14.4 cm long; 8-18 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; elliptic; 8-14 cm long. Primary panicle branches spreading; 2-4 cm long. Panicle axis angular; pubescent. Panicle branches angular; pubescent; with prominent pulvini. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-3 mm long; pubescent.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 8-14 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; 8-14 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; 0.5 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.5 mm long; 0.05 length of adjacent fertile lemma; membranous; 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 barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 5-6 mm long; 0.33-0.5 length of fertile lemma; chartaceous; 3 -veined; acute. Lemma of upper sterile floret ovate; 6.3-7.3 mm long; chartaceous; acute. Fertile lemma ovate; 11.7-14.5 mm long; coriaceous; without keel; 11 -veined. Lemma apex apiculate. Palea 13-14 mm long; 6 -veined. Palea keels contiguous above a sulcus.
