EDITORS PREFATORY NOTE. 



considerable atteution 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.
