I formerly was unable to find clear distinctions in the descriptions of R. Swinhoei 

 Hance and R. hupehensis; therefore I combined the two species. Now I think, 

 however, that there are constant characters by which the two plants can be dis- 

 tinguished. R. Swinhoei is evergreen, whereas R. hupehensis seems to have de- 

 ciduous leaves.

 231 (1887). — Focke in Bibl. Bot. LXXII. 43 {Spec. Ruh.) (1910).

Ternate and simply trifid leaves occur on the same branches of Mr. Wilson's 

 specimens. This shows that R. bambusarum cannot be separated from R. Henryi.
