I should have referred this bamboo to Arundinaria if it were not for the 
6-merous andreecium and the shape and structure of the pistil. At the same 
time I am not satisfied with its position in Bambusa, where it occupies an 
isolated position on account of its slender rambling growth, the comparatively 
delicate eataphylls, and the texture of the valves.
