Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 300-1400 cm long; 20-70 mm diam.; woody; without nodal roots. Culm-internodes terete; thin-walled; 15-40 cm long; mid-green; distally glabrous. Culm-nodes flush with internodes. Lateral branches dendroid. Bud complement 1. Branch complement several; in a clump; thinner than stem. Culm-sheaths deciduous; coriaceous; pubescent; with dark brown hairs; hairy on margins; auriculate. Culm-sheath ligule 5 mm high; dentate. Culm-sheath blade triangular; glabrous on surface, or pubescent. Leaves 5-11 per branch. Leaf-sheaths 4-6 cm long; puberulous. Leaf-sheath oral hairs setose; dark. Leaf-sheath auricles falcate. Ligule an eciliate membrane; erose; obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2-0.4 cm long. Leaf-blades deciduous at the ligule; lanceolate; 10-25 cm long; 12-25 mm wide. Leaf-blade venation with 12-18 secondary veins. Leaf-blade surface glabrous; hairless except near base. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 25-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Fertile
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 25-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Morphology Reproductive morphology Inflorescences Bracts Glume
