* I am much indebted to Dr. 

 Hooker for having sent me many 

 plants from Kew ; and to Mr. 

 Veitch, of the Royal 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 occasions, much infor- 

 mation and many references.
