CONTRIBUTIONS TOWARD A FLORA OF CAITHNESS 225 



this one I have endeavoured to give at least one locality to 

 those species that we then did not localise ; besides adding 

 many localities to the rarer species, and such new records 

 as I have been able to accumulate since 1900 ; so that the 

 future writer of a Flora of the County may have before him 

 the material as it has been got together. No doubt there 

 is material elsewhere, and I should feel much indebted to 

 anyone for the slightest information respecting the Flora. 

 It is probable there is information still to be gleaned from 

 Robert Dick's herbarium ; and I had hoped some day to 

 visit the county. Since Mr. Grant left Wick I have had 

 no information as to the condition of Dick's herbarium. It 

 would have been well if that collection had been sent to 

 Edinburgh or London to be carefully examined, noted, and 

 returned. 



As the northern-most county of the mainland of Scotland 

 the Flora of Caithness is especially interesting ; and when 

 more complete it can then be compared with that of Shetland 

 and Orkney, as well as of the Faroes. 



I have also discussed as shortly as possible the claims 

 of some species as Caithness plants ; no doubt, could we have 

 the evidence obtained by Robert Dick from about 1836, we 

 should be able to judge with some certainty the status of 

 many species, but this was lost at his death. I have copied 

 Mr. Watson's remarks on the marked catalogues sent him, 

 as these may be of interest to Scottish botanists to show 

 how he worked.

Sandside Bay, Caithness, July 183 i. 1 Mr. Watson's, 

 MS., No. 40 at Kew. 



2. Dr. R. Brown, Campster. London Catalogue, ed. 6, 



checked for plants seen in the county of Caithness, 

 partly by himself, partly by the late Mr. R. Dick, 

 with some additions subsequently (1872) made to 

 the original list drawn up in 1861-2, by Mr. C. W. 

 Peach (No. 161). 



3. Mr. J. Grant, Wick. London Catalogue, ed. 7, 



marked for Caithness, 1880 (No. 162).
