CXC FLORA OF BERKSHIRE 



tion of these records lias co>t the author much time and labour, 

 partly because the earlier botanists lived on the border of the 

 county, so that it is often doubtful whether the plant was actually 

 seen in Berkshire. In many cases localities are stated in general 

 terms, such as 'about Oxford,' 'about Pangbourn,' 'about Keading,' 

 which maybe either in Oxford or Berks, or in both counties, or 'about 

 Bagshot,' which may be either in Berks or Surrey. The author has 

 tried to interpret these vague records in a satisfactory manner, but he 

 cannot pledge himself in some few cases to absolute accuracy. 



Underneath the paragraph devoted to the first record are ranged 

 the localities which are given to those plants which it is deemed 

 necessary to distinguish in this way. The topographical names are 

 spelt as on the Ordnance Maj), and are arranged according to the 

 river districts : — 



ist, those which are drained by the Isis or Upper Thames.

The author is responsible for all the records to which no recorder's 

 name is attached, and a note of admiration (!) after a record signifies 

 that the author has seen the plant in the locality to which it is 

 appended. All records which are not those of his own discoveiy have 

 the authority for their occurrence printed in italics : occasionally more 

 than one botanist has recorded a plant from the same locality ; in 

 such a case, priority of discovery has the preference. When a plant 

 is \erj rare the date of the last notice of it is usually appended. 

 After the records a paragraph is devoted to any local peculiarity of 

 structure or distribution, &c. , which may be thought interesting. 



The named varieties of the plant are treated in a similar way to the 

 plant itself, so far as nomenclature and distribution are concerned, 

 but the nomenclature of the varieties is avowedly less perfect and 

 ^complete than that of the species. When a plant has no detailed list 

 of localities enumerated, it is because it is one of the common species 

 of the county. 



Lastly, the occurrence or non- occurrence is noted of each plant in 

 the bordering counties. 



Notices of species not found in Berkshire are enclosed in brackets [ ], 

 and the names are printed in small Roman capitals. 



At the end of the Flora proper a summary of the Berkshire plants 

 is given, in which the total number of Berkshire species is enumerated, 

 and the grade of citizenship is stated to which they can lay claim. 

 Very rare plants and plants which have become extinct in the county 

 are specially noticed, and a brief sketch is given of the comparative
