Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms 1000-2000 cm long; 60-100 mm diam.; woody. Culm-internodes terete; thick-walled, or solid; mid-green; distally glabrous. Lateral branches dendroid. Culm-sheaths glabrous; without auricles, or auriculate; setose on shoulders; shoulders with 4-8 mm long hairs. Culm-sheath blade lanceolate; 5-20 cm long; brown pubescent. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs setose. Leaf-sheath auricles falcate; 20-35 mm long. 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; 16-24 cm long; 30-51 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; lax; with glumaceous subtending bracts; prophyllate below lateral spikelets; leafy between clusters. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 6-10 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 35-60 mm long; 4-5 mm wide; breaking up at maturity; disarticulating below each fertile floret.
