Morphology General Habit
Perennial. Culms scandent; pendulous at the tip; 500-1000 cm long; 10-15 mm diam.; woody; without nodal roots. Culm-internodes channelled; distally glabrous, or pubescent. Lateral branches dendroid; infravaginal. Bud complement 10-24. Bud prophyll 40-75 mm long. Branch complement many; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths persistent; 16-34.3 cm long; antrorsely scabrous. Culm-sheath ligule 0.5 mm high; ciliate. Culm-sheath blade triangular; indistinctly demarcated from sheath; erect; 2.7-7 cm long; hispid. Ligule an eciliate membrane; 1 mm long; truncate. Collar with external ligule. Leaf-blade base asymmetrical; with a brief petiole-like connection to sheath; petiole 0.2-0.4 cm long. Leaf-blades lanceolate; 7-16.6 cm long; 10-24 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous. Leaf-blade apex attenuate; filiform.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle; without bracts, or bracteate at branch bases, or bracteate at pedicel base; embraced at base by subtending leaf. Panicle open; linear; 9-22 cm long. Primary panicle branches appressed; 2.5-3 cm long. Panicle axis angular; scabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-5 mm long; scabrous.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7.1-8.5 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 oblong; laterally compressed; 7.1-8.5 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; 1-1.2 mm long; membranous; without keels; 1-2 -veined. Lower glume lateral veins absent, or obscure. Lower glume surface asperulous. Lower glume apex acute. Upper glume ovate; 1.6-3 mm long; 0.33 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface asperulous. Upper glume apex acute; mucronate.
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; 2.9-3.2 mm long; 0.5 length of fertile lemma; chartaceous; 7 -veined; scaberulous; acute. Lemma of upper sterile floret ovate; 5.6-6.2 mm long; chartaceous; scabrous; acute; mucronate. Fertile lemma ovate; 6.4-7.5 mm long; coriaceous; without keel; 6 -veined. Lemma surface scaberulous. Lemma apex acute, or apiculate.
Morphology Reproductive morphology Flowers
