vi PREFACE 



The letterpress has been entirely reset in new type, and advantage hat) 

 been taken of this fact to give an improved page, and by using a variety of 

 types to make reference easier. The popular name of each species is also 

 given precedence, as is fitting in a popular work, the scientific name following 

 in italics. In the List of Contents the scientific name comes first, in order 

 that all the species of a genus may be found together, but the reader who 

 would seek any particular plant under either of its English names will 

 find ample provision has been made for him in the several Indices at the end 

 of the work. In previous editions the Flowering Plants and Rushes were 

 indexed independently of the Grasses and Ferns, the former Index appearing 

 at the end of Volume III. This arrangement had the efTect of breaking the 

 work into two, and has now been discarded in favour of a comprehensive 

 General Index, which will be found in Volume IV.
