Considering the extent of the two first of these areas it becomes evident 

 that the Philippines have a rich representation of the species of this 

 group. The most recent collections have so added to our list of species, 

 that it is probable that it may still have to be considerably enlarged. 



A nomenclatural difficulty has arisen through the publication since the 

 beginning of 1908 of several Philippine species without an accompanying 

 Latin diagnosis. To avoid misunderstanding, it may be said that they 

 are here accepted as published, though to add certainty, such a diagnosis 

 has been added where the species has been accepted as valid, and that 

 when the limits here assigned to such species differ from those of the 

 original author, that his type is in all cases to be considered as that of 

 the species.

The former collection seems clearly of this species, the latter is identical 

 vegetatively, but the calyx of the male flowers varies in length from 1 to 8 mm, 

 presumably with age, and the lobes are not emarginate. This genus being usually 

 divided by the size of the calyx, the second specimen would appear distinct, but 

 it is thought best not to separate it, at least until more complete material can be 

 secured.
