PREFACE 



TO THE SECOND EDITION. 



It was Mr. Watson's intention to publish a second 

 edition of this work, and to entirely recast it and re-write 

 the introductory and explanatory portions. This he did 

 not live to accomplish, but he made preparation for it by 

 keeping an interleaved- copy of the first, edition always at 

 hand and entering in it regularly all the records of the 

 occurrence of plants in additional vice-counties that came 

 to his notice. The few additions which we have made on 

 our own responsibility may be distinguished by having the 

 name of the personal authority placed within parentheses. 

 Out of the nine vice-counties, for which in 1873 there were 

 no lists for even the commonest plants, only two now 

 remain totally unreported upon, so that in this edition all 

 the vice-counties are dealt with in the same manner. His 

 notes for the remodelled, introductory, and explanatory 

 chapters are too incomplete to be used, so that we have 

 reprinted those of the first edition, with only a few trifling 

 alterations that were rendered needful by changed circum- 

 stances. His" British Herbarium has now been brought to 

 Kew, his European collection presented to Owen's College, 

 Manchester, and his small general herbarium, formed in 

 his student days, sent to Baron Ferdinand von Mueller 

 at Melbourne.
