The above list is not to be received as an exhaustive one for 

 works which treat on topographical botany in this country. It 

 includes those only which stand on my own bookshelves, and 

 have been used more or less in writing this present and other 

 antecedent books. Two local Floras are left out simply because 

 copies do not chance to be on those shelves, namely, for 

 Sidmouth and Tonbridge ; possibly there may be others wholly 

 unknown to me, although deserving of notice ; certainly there 

 are other books intentionally ignored, as including a dangerously 

 large admixture of error amid what is sound. Some little of 

 British topographical botany, mostly good as far as it goes, is 

 to be found scattered in the Annals of Natural History, under 

 various Editors ; and even in the Linnean Transactions. Only 

 very imperfect sets of these two serials are in possession. 



A few old writers have been named in the above list, such as 

 Ray and Dillenius, because some very few counties still rest on 

 their original records, repeated by more recent writers seemingly 

 without having been verified afresh. Throughout my own 

 topographico botanical writings, and more especially in this 

 present work, the leading object has been to shew the botany of 

 Britain as it actually exists, or did very recently exist, in living 

 reality on the ground. But no single botanist ever sees more 

 than a portion of the surface of the ground and its floral covering. 

 And if his writings are required to cover all, at any rate,
