MERRILL. 
1906. Mindanao, Province of Surigao, Aliern 330 ; District of Davao, Williams 
2941 . 
A widely distributed endemic species, for which the earliest valid specific 
name is here adopted. The type of Voacanga cumingiana Rolfe was Cuming 1S0G 
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.
