A FLORA OF THE ENGLISH LAKE 

 DISTRICT. 



INTRODUCTORY EXPLANATIONS. 



Names and Species-limits. — There are at the English Lakes 

 just 50 ferns and nearly 850 flowering plants that are thoroughly 

 wild, and we may count 100 more if recent introductions be 

 included in the estimate. In the sequence, nomenclature, 

 and limitation of species, I have followed Watson, so that 

 in these points the present work is uniform with ' Cybele 

 Britannica,' ' Topographical Botany,' and the earlier editions 

 of the London Catalogue, and also with my own former books 

 on the botany of the north of England, ' North Yorkshire,' 

 and the ' New Flora of Northumberland and Durham.' The 

 numbers have been widely used in the distributions of the 

 London Botanical Society and the Botanical Exchange Club, 

 but they are changed in the last edition of the London 

 Catalogue. In this work I have only numbered the species 

 that have a reasonable claim to be regarded as wild plants 

 of the Lake district. A break in the regular sequence of the 

 figures consequently indicates that plants that grow wild 

 somewhere else in Britain are not found at the Lakes. 



Classes of Citizenship. — These are to be understood as used 

 in the same sense as in Watson's ' Cybele Britannica,' where 

 they are fully defined and explained. By a ^Native' is 

 meant a plant which, so far as present appearances show, 

 has established itself quite independently of man's interven-
