174 ANNALS OF SCOTTISH NATURAL HISTORY 



specimens, I have included in this list the names of all 

 specimens in my herbarium, which are either additional to, 

 or confirm doubtful records of, the plants recorded from 

 county No. I I I Orkney, in the second edition of the above 

 mentioned work. 



Except where otherwise noted, the specimens have been 

 identified by the late Dr. J. T. I. B. Boswell, author of the 

 third edition of Sowerby's " English Botany." 



In the case of those plants which have already been 

 recorded from Orkney, references are given in the following 

 list, under each species and variety, to the books in which 

 the records have been published. These records are prin- 

 cipally contained in the Annual Reports of the Botanical 

 Exchange Club of the British Isles ; " A New List of the 

 Flowering Plants and Ferns of Orkney," edited by W. A. 

 Irvine Fortescue, and published in the " Scottish Naturalist " 

 for 1882 and 1883; and "Additional Records of Plants 

 from Scotland," by Arthur Bennett, published annually in 

 the " Scottish Naturalist" since 1886 inclusive. 



The nomenclature followed is that of the second edition 

 of Watson's " Topographical Botany," except in the case of 

 species and varieties which are not recorded in that work. 

 In the latter case the nomenclature adopted is that of the 

 seventh edition of the " London Catalogue of British 

 Plants." 



Non-native plants, which have become naturalised in 

 Orkney, are distinguished by an ^ prefixed to the names, 

 and the names of casuals and escapes from cultivation are 

 printed in italics. 



Of the 5 5 species and varieties recorded from Orkney in 

 the following list, 46 are native, 3 are naturalised, and 6 are 

 either casuals or escapes from cultivation.
