A very characteristic endemic species, definitely known only from the 
mountains of the Provinces of Laguna and Tayabas, Luzon. 
As to the specific name cumingii it is retained in spite of the fact that A. 
DeCandolIe coined a new name, philippinensis, for the species, on account of 
the fact that Klotzsch had at about the same time published Petermannia 
cumingiatia which De Candolle transferred to Begonia as B. cumingiana. While 
the Vienna Code recommends that in the future the use of both the genitive and 
adjectival forms of the same name for two different species of the same genus 
be avoided, no definite ruling is made as to the treatment or validity of such 
names that have already been published; the inference is that both are valid.
