Hab. Bonin : Chichijima, leg. H. Hattori. 190 ). 



.\s the plant bears an aspect remarkably different from tbat o£ P. serpens, it should be 

 better regarded as a dislinct species. The leaves o£ the new plant are very much larger thaa 

 those of P. sa-pen^t, and the branches of the former are scandent and prostrate, but not rooting 

 as is the aase ■«•ith the latter species. I have examined all the specimens o£ P. .'■erpens fnia. 

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

 shai>e of the leaves and in the habit.
