Khizome widely creeping. Culm erect, attaining about 12 m. or more 

 in height aud about 2 deciin. or more in diameter, terete, broadly grooved 

 above, but semiterete in the uppermost portion, fistulose, smooth, green or 

 yellowish ; internodes short ; nodes slightly prominent, but more turged 

 above, pubescent and ringed with white waxy substance below it when 

 young ; main-branches 2 to a culm-node, semiterete, turged at nodes, 

 branchlets usually 1 to 2 to a node. Culm-sheath large, coriaceous, 

 densely pubescent with brown-purple hairs, fimbriate at the top, with a
