* I am much indebted to Dr. 

 Hooker for having sent me many 

 plants from Kew; and to Mr. 

 Veitch, of the Eoyal Exotic Nur- 

 sery, for having generously given 

 me a collection of fine specimens' 



of climbing plants. Professor Asa 

 Gray, Prof. Oliver, and Dr. Hooker 

 have afforded me, as on many 

 previous occa^ions, much infor- 

 mation and many references.
