VI PREFACE. 



unpublished sources, contains biographies of several botanists 

 of whom little has hitherto been known but the names, and 

 may in part be regarded as supplementary to Dr. Pulteney's 

 well-known Sl-eiches of Botany. 



To the numerous correspondents who have helped us in 

 the comiDilation of our material we offer our thanks. Those 

 botanists to whom we are chiefly indebted are enumerated on 

 p. 11 ; but the Rev. W. W. Newbould requires special mention 

 here, for his care in helping to correct the proof-sheets. 

 To the Hon. J. Leicester Warren for his help in the Rubi, to 

 Mr. Worthington G. Smith for his list of Hymenomycetous 

 Fungi, and to the Rev. James M. Crombie for his note on the 

 Lichens, our acknowledgments are also due. 



The size of this volume may appear to be excessive in com- 

 parison with the importance of the subject ta'eated in its pages ; 

 it has indeed considerably exceeded the bulk originally con- 

 templated, but, with the exception of some localities which the 

 peculiarities of the county seemed to render it desirable to put 

 on record, there is, we believe, very little irrelevant matter ; 

 indeed, some care has been expended on concentrating the 

 material. 



From those who have ever been occupied in endeavoiu-ing to 

 estimate, each at its true value, the mass of alleged facts which 

 go to make up a local Flora, we need scarcely ask for indul- 

 gence. We have, in all cases, endeavoured to be just to others 

 as well as to ourselves. 



August, 1869.
