INTRODUCTION. 
The uses of a local Flora are threefold: Firstly, It en- 
ables a resident in the district, or a visitor, to know what 
plants may be found, and where. Secondly, It shows the 
comparative prevalence of certain species to that of other 
districts. And thirdly, It forms a depository of facts rela- 
tive to the range of species, by indicating more numerous 
stations than could be done in a general Flora ; and afford- 
ing more scope for allusion to the associations which various 
plants awaken in the mind, — and this part of the subject, 
which invests its study with a peculiar charm, is daily be- 
coming more appreciated. In accordance with these views 
the following pages have been written. 
The arrangement and nomenclature adopted are those of 
Hooker s British Flora ;* and to prevent any confusion of 
names, the authority for each genus and species is given, to- 
gether with the principal synonymes. The English name is 
added, and after it a reference to the page of the British 
Flora (H.), and to that of Babington’s Manual f (B.), 
where the characters and descriptions of the species are to be 
found. 
It is not in accordance with the rules laid down by some 
of our best botanists for the construction of a local Flora, 
* Hooker’s British Flora, 5th ed. London, Longman & Co. 1842. 
+ Babington’s Manual of British Botany. London, Van Voorst. 1843. 
There is a new edition of this work published lately, and if it is referred to, 
the almanac weather rule may have in some instances to be applied, viz., 
the page before or the page after.
