VI EDITORS PREFATORY NOTE. 



considerable attention to the group in question. To him I now offer my 

 hearty thanks. The glossary of botanical terms makes claim neither to 

 completeness nor originality. Though a large number of the definitions 

 and explanations have been written specially for this book, I have never 

 hesitated to lay published sources under contribution. The laborious task 

 of constructing the index has fallen to Mr. George Brebner, and to him is 

 due the gratitude of such as gain through it direct and ready access to the 

 body of the work.
