226 ANNALS OF SCOTTISH NATURAL HISTORY 



It was marked thus : " Red C." Caithness plants so 

 marked by Dick. " Black C."- -Do. wild plants not marked 

 as such in Dick's Herbarium, though several are virtually so, 

 or referred to in Smiles' " Life of Dick." 



t Plants occasionally found wild in Caithness, but 

 probably or evidently introduced. 



Garden escapes, trees in plantations, weeds of cultiva- 

 tion, casuals, aliens, etc. 



I have collated this with my own Catalogue and papers 

 on the Flora, and additions are here given. Those marked 

 as " Garden escapes, etc.," I have marked with the star. 



ANEMONE NEMOROSA, L. Marked by Mr. Nicolson in his catalogue 

 for Caithness; on record for 108 counties. 



Mr. Nicolson (I.e.} mentions that specimens of aquatic 

 Ranunculus from Staxigeo " vary much, and on comparing 

 them with the descriptions and figures in Sowerby's " Eng. 

 Botany " one seems to have a choice between calling them inter- 

 mediate forms of R. Drouetii, R. Baudotii vulgaris, and R. 

 Baudotii confusus, or supposing the differences between them 

 are imaginary." 



Now there is no better defined species of the aquatic 

 section than R. Baudotii, and the differences from R. Drouetii, 

 even when dried, and still more when living, are so definite 

 that it suggests that his specimens may be hybrids, as I do 

 not remember, in the thousands of specimens that have passed 

 through my hands, Baudotii ever being named Drouetii or vice 

 versa.
