PHILIPPINE PHYLLANTHIKffli. 75 



first made by Hamilton in Wallich's catalogue, but does not seem to have been 

 published till 1883. Failure to find any older name has compelled the use of 

 Willdenow's Phyllanthus virosus, although it was he who also originated the 

 other specific name as Xylophylla obovata. 



Vicca pentandra Blanco has been reduced here by Mueller, Merrill, and Villar, 

 and there can be no doubt that they were correct, although the description is not 

 exact in some details. It will be noted that this species has been recently collected 

 at what is practically Blanco's type locality. The reduction of F. leucopyrus F.- 

 Villar is pure guesswork, based on the fact that it has not appeared in any recent 

 collection. 



Securinega ovata Muell. is merely listed by Vidal; there is no such species, but 

 he elsewhere cites 8. obovata as a synonym of F. obovata, which is correct, and it 

 is probable that the earlier name is only a misprint.
