I am of the opinion that there is ample reason to separate this from Dinochloa 
scandens, not only on account of the pubescent panicle-rachis, but also on account 
of the emarginate glumes, long-plumose stigmas, and the presence of lodicules 
Hutchinson gives the vernacular name as bucao, Everett as cawayan.

This seems to me to be quite distinct from D. scandens var. angustifolia, in 
the scabrous culms, the thin leaves, and the quite different caryopsis. At the 
same time, I have ventured to describe it as a separate species only with some 
diffidence, for I feel that as all the available Dinochloa specimens are more or 
less imperfect in some respect, nothing will really set right their separation but 
a careful and complete study on the spot. None of the specimens have any 
culm-sheaths, only one has fruit, and some have the flowers far too young for 
study. Aguilar gives the vernacular name as baito ; Curran as esu.
