ADDITIONS AND CORRECTIONS TO THE TOPO- 

 GRAPHICAL BOTANY OF SCOTLAND. 



By JAMES W. H. TRAIL, A.M., M.D., F.R.S. 



IN this journal, during the years 1898, 1899, and 1900, I 

 endeavoured to give in the briefest possible form an abstract 

 of the distribution, so far as then known, of all plants grow- 

 ing in Scotland not evidently in cultivation. Their distribu- 

 tion was indicated by the methods used by Mr. H. C. Watson 

 in his " Topographical Botany of British Plants," the counties, 

 or parts of counties (" vice-counties "), being numbered from 

 72 to 112 inclusive. These divisions, though not natural, 

 are so familiar otherwise, and have been so generally made use 

 of in past records, that they offered considerable advantages 

 in the attempt to sum up what was known. I also sought 

 to ascertain as far as I could, and to indicate, the claims of 

 the several plants to be regarded as " native " or existing in 

 Scotland apart from human agency. Rubus and Hieraciuni 

 formed the subjects of separate papers in this journal, and 

 Salix was unfortunately omitted by mischance. 



In dealing with so great a multitude of figures it was

inevitable that errors should occur, both of omission and of 

 commission ; and in estimating the claims of doubtful species 

 to be accepted as " native " one is naturally impressed by the 

 conditions familiar to oneself, and may misjudge the evidence
