The main purpose of this article is to call attention to the presence in 

 the Philippines of the genus Ascarina, though still known here from 

 only one collection. It has hitherto been reported from New Caledonia, 

 Polynesia, and Xew Zealand, but from none of the regions the flora of 

 which is closely allied to that of the Philippines. The one remaining 

 genus of the family is exclusively American.
