As suggested by Doctor Hackel in a manuscript note attached to Schizostachyum 
Dielsianum (Merrill 711), this species and 8. Dielsianum are not easy to separate, 
but I have attempted to arrange the material sent me and found that in general my 
identifications agree with Mr. Merrill’s at page 391 of his paper on the Philip- 
pine grasses. I am inclined to think his suggestion that the Bambusa Lwmampao 
Blanco is this species is most probably correct. S. Dielsianwm has the glomerules 
of spikelets usually open and scattered and a different texture of leaf. The 
vernacular name is usually given as bical ; Topacio gives it as guimac.
