320 MERRILL. 



1900. Mindanao, Province of Surigao, Ahem 330; District of Davao, Williams 

 2!)f,l. 



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

 name is here adopted. The type of Voaoanga cumingiana Rolfe 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.
