By C. B. Robinson. 
( From the Botanical Section of the Biological Laboratory, Bureau of Science, 
Manila, P. I.) 
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 New 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.
