398 MONOGRAPH OF THE BRITISH SPECIES OF EUPHRASIA. 



complete. There can be no doubt that it will be many years before 

 this knowledge will be obtained. 



My best thanks are due to those botanists who have assisted me 

 in communicating specimens ; they are especially due to W. H. 

 Beeby, Esq. ; also to Messrs. Ar. Bennett, J. Britten, N. Colgan, 

 H. and J. Groves, S. M. Macvicar, W. F. Marshall, W. S. Millar, 

 E. Lloyd Praeger, W. H. Purchas, E. S. Salmon, and Prof. Wett- 

 stein. I have been assisted so largely by Prof. Wettstein that I 

 can hardly sufficiently express my thanks and indebtedness to him. 

 He has seen most if not all doubtful plants, and given me his 

 opinion on them. He has given me fall permission to make copies 

 of the schemes and drawings of leaves, bracts, &c. in his Mono- 

 graph, a permission which I have taken full advantage of. His 

 diagnoses of species are so excellent that I have mostly adopted them.

* I enter here the description of this species, though I cannot ascertain 

 that it is a native of Great Britain. It is given by Prof. Wettstein, as on my 

 authority, as occurring in " Surrey : Downs (Ig. ? H. Townsend,") Mon. p. 103 ; 

 but I have never collected specimens in England nor have I seen native ones. I 

 have had correspondence with the Professor on the subject, but he is unable to 

 tell me how the error crept in.
