X INTRODUCTION. 



Linnaeus, and numerous synonyms are added. An account 

 of Mr Lyons will be found in Cooper's Annals of Cambridge, 

 iv. 381. 



The next -work relating to the plants of our county is 

 the Flora Cantabrigiensis of Eelhan. The first edition of 

 this book appeared in 1785 and was quickly followed by 

 three Supplements, published in 1786, 1788, and 1793 re- 

 spectively. The second edition of the Flora issued from 

 the press in 1802, and the third and last in 1820. Messrs 

 Turner and Dillwyn inform us that Eelhan had "himself 

 seen every species in the station he has assigned to it in 

 his Flora;" but I have some doubt concerning the correct- 

 ness of this statement, because many of the localities seem 

 to be only repetitions of those recorded by his predecessors. 

 Mr H. C. Watson thinks that Eelhan's Flora included " the 

 borders of the counties adjoining Cambridgeshire,'' and 

 extended " a considerable distance into Norfolk ; " but that 

 seems not to be the case. Eelhan included the small piece 

 of Suffolk adjoining the town of Newmarket (as also did 

 Eay); but, as far as I have seen, gives no other locality 

 which lies beyond the boundaries of the county, and omits 

 several so situated which are recorded by Eay in the 

 Catalogus. Probably Mr Watson was misled by the fact 

 that there are places named Swaffham and Thetford in 

 Cambridgeshire as well as in Norfolk. 



Eelhan's Flora contains a valuable account of the 

 Mosses, Algse, and Fungi found in the county. These 

 orders are not included in the present Catalogue on ac- 

 count of their study having been too much neglected to 

 allow of a proper list of them being now made.
