PREFACE. 



The Flora of Plymouth gives particulars concerning tlie Wild 

 Plants and Ferns growing within twelve miles of the town. 

 Notes made from personal observation of the various species 

 during the past twenty years are combined with all the printed 

 records of importance that I have been able to find concerning 

 them. The preparation of the work was commenced several 

 years ago, at the suggestion of my friend Mr. J. G. Baker, 

 when on a visit to the neighbourhood of Plymouth. Aid 

 obtained at various times through occasional correspondence 

 with many botanists has helped me on in the undertaking ; and 

 I have to express the obligations I am under to Mr. H. C. 

 Watson, Dr. Boswell, Professor Babington, Mr. J. G. Baker, 

 and others, for having favoured me with their views on certain 

 of the critical species. 



To M. Deseglise, of Geneva, I am indebted for many speci- 

 mens of Continental Roses, and also for notes on some of the 

 Plymouth ones. Dr. Focke, of Bremen, and Professor Ares- 

 choug, of Lund, have assisted me in my study of the Eubi by 

 supplying a considerable number of Continental specimens. I 

 am under obligations to Mr. B. Daydon Jackson and Dr. H. 

 Trimen for having taken the trouble to copy out and forward 

 extracts from two or three of the earlier British botanical 

 writers. Mr. H. Groves has kindly given his opinion on the 

 Charae. Two Plymouth friends, Mr. R :N". Worth and Dr. J. 

 Merrifield, have rendered most valuable assistance by kindly 

 looking over and revising the portions of the Introduction that 

 respectively relate to Geology and Climate. To the latter
