 29J,1- 



A widely distributed endemic sjjecies, for which the earliest valid specific 

 name is here adopted. The type of Voacanga cumingiana Rolf^ was Cuming 1806 

 from Negros, and while it has somewhat smaller leaves than most of the specimens 

 cited above, I consider it to be identical with Blanco's species.
