This is the first representative of the genus to be found 

 in the Sun da Islands, several species being known from New 

 Guinea, one from north-eastern Australia, and several from 

 Polynesia. The present species is dedicated to Mr. D. M. 

 Matthews, Conservator of Forests, British North Borneo, and 

 differs from the genus as described in its distinctly 1-celled 

 ovaries, and in its equal or subequal, not didynamous stamens. 

 It is, however, in all essential characters a typical Faradaya.
