Bancalan, between Palawan and Balabac, C. M. Weber, Sep- 

 tember 2, 1916, in forests, altitude about 3 meters. 



A species well characterized by its few-nerved leaves and 

 large fruits, by which it is readily distinguished from Omphalea 

 philippinensis Merr. and 0. malayana Merr. ; the fourth species 

 for the Philippine-Malayan region. It is dedicated to Dr. C. S. 

 Sargent, director of the Arnold Arboretum, under whose aus- 

 pices Weber's collection was made.
