FBANCIS BUCHANAN WHITE. 49 



glandular and aciculate form with roundish greyish leaflets, which 



1 have seen in good quantity in N.E. Yorks, Berks, and N. Hants, 

 and received from W. Kent [Wolley Dod) and Surrey {A. Ley) ; see 

 Joimi. Bot. 1894, 41. 



E. LiNDEBERGii P. J. Muell. Joum. Bot. 1892, 114. No. in 

 Set, 55. 11 v.-c. (34, 36, 39, 42, 43, 55, 57, 62, 64, 65, 88). 



E. DUMNONiENsis Bab. Joitrn. Bot. 1890, 338, 339. No, in Set, 27. 

 19 v.-c. (1-6, 9, 11, 12, 14, 22, 23, 34, 36, 49, 52, 97, 98, 103). The 

 more I see of this the more my conviction grows that it must be kept 

 apart from Pi. rhamnifolvm, coming in between it and R. villicanlis. 



E. MERcicus Bagnall, Jouni. Bot. 1892, 372. No. in Set, 31. 



2 v.-c. (38, 57). [43] . Not really yet found in Staffordshire, as 

 was supposed by Mr. Bagnall. Mr. Griffith's Carnarvonshire and 

 Anglesey plant, placed here by Dr. Focke {B. E. C. Rep. 1894, 405), 

 can only be associated with R. mercicus, I think, as a very strongly 

 marked var., differing from it more decidedly than the following 

 plant. 



Var. b. bracteatus Bagnall, Joum. Bot. 1894, 187. 1 v.-c. (38). 



E. viLLicAULis, sp. collect. 52 v.-c. (2-9, 11, 12, 16, 17, 18, 22, 

 27, 33, 35, 36, 38, 39, 40, 42, 46-49, 52, 54-60, 62-65, 69, 70, 72, 

 77, 86, 88, 89, 96-98, 103, 105, 106, 108). 



a. R. vilUcaulis Koehl. 2 v.-c. (106, 108). The typical plant, 

 I suppose, and apparently different from all English forms known 

 to me, though coming very near to var. insularis (F. Aresch.). 



Var. b. Selmeri (Lindeb.), Joum. Bot. 1894, 43 (for this and the 

 two next vars.). 46 v.-c. (the same as those given above for the 

 species collectiva, except 17, 33, 54, 72, 106, 108). I. One of our 

 most widely spread and easily recognised brambles, usually abundant 

 and luxuriant on our sandy heaths. 



Var. c. insuJaris (F. Aresch.). 7 v.-c. (9, 39, 49, 52, 72, 97, 106). 



Var. d. calvatus Blox. (as var. of R. Salteri Bab. in Land. Cat. 

 ed. 8). 5 v.-c. (17, 38, 39, 55, 57). 



E. RHOMBiFOLius Weihe. No. in Set, 9. 11 v.-c. (5, 6, 11, 17, 

 18, 22, 32, 36, 49, 56, 57). [110] .

FEANCIS BUCHANAN WHITE. 



Francis Buchanan White was born in Perth on March 20th, 

 1842, where his father, Dr. Francis J. White, who still lives in 

 Perth, retired, was for many years one of the leading medical 

 practitioners. He studied medicine in the University of Edinburgh, 

 taking the degree of M.D. in 1864. His thesis, which received 

 commendation, showed the bent of his mind, the subject being 

 "On the Eelations, Analogies, and Similitudes of Insects and 

 Plants." Throughout his life he preserved his broad interest in 

 natural science, his inclination tending much more to the study of 

 nature out of doors than to the exercises of the laboratory and the
