 Farlow had sent him a Dermocarpa from Japan which appeared 

 to he identical with the Færoese specimen, and he very kindly 

 forwarded me a preparation of the Japan plant, which also ap- 

 peared to me lo agree exactly with mine. Dr. Bornet also told me 

 llial he had written to Prof. Farlow on the subject, and Farlow 

 had answered that he had nol described the plant. Before I give 

 a description of il I mav add that I have done rnyself the pleasure 

 of naming il 1). Farlowii in honour of ils lirsl observer.
