HAB. Bonin : Chichijima, leg. H. HATTOKI. 1905. 



As the plant bears an aspect remarkably different from that of P. serpens, it should be 

 better regarded as a distinct species. The leaves of the new plant are very much larger than 

 those of P. serpent, and the branches of the former are scandent and prostrate, but not rootiug 

 as is the case with the latter species. I have examined all the specimens of P. terpens from 

 Japan, Formosa and Hongkong ; but none does ever seem to approach to the Bonin plant in the 

 shape of the leaves and in the habit.
