Somewhat near P. taiwanensis 

 HAYATA or P. lucida SCHN., but 

 separable from it by the quite gla- 

 brous and much smaller leaves. Too 

 imperfect for a description.

The present plant was identi- 

 fied by myself with the Himalayan 

 P. utilis only by the external comparison of the branches. In examining 

 the. tree in the mountains in Formosa, I became very much sceptical of the 

 identification. It is a shrub of scandent habit like Celastrus articulatus, 

 trailing and climbing up to the top of other tall trees, and sending its 

 branches downwards. This habit is, it seems to me, totally different from 

 that of the Himalayan plant and also from the Chinense P. sinensis OLIVER.
