Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect (arching); 500-1000 cm long; 10-25 mm diam.; woody; with root thorns from the nodes. Culm-internodes terete; thick-walled, or solid; yellow, or light green, or mid-green. Lateral branches dendroid. Branch complement two, or three; with 1 branch dominant; thinner than stem. Culm-sheaths deciduous but leaving a persistent girdle. Leaf-sheaths outer margin hairy. Leaf-sheath oral hairs setose; 5-7 mm long; dark. Ligule a ciliolate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.05-0.1 cm long; petiole pubescent. Leaf-blades lanceolate; 8-14 cm long; 4-10 mm wide. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
