INDEX TO AMERICAN BOTANICAL LITERATURE 
(1907) 
aim of this Index is to include all current botanical literature written by 
Americans, published in oe or based upon American material ; the word Amer- 
ica being used in its broadest sen 
Reviews, and papers which ins exclusively to forestry, agriculture, horticulture, 
manufactured products of vegetable origin, or laboratory methods are not included, and 
no attempt is made to index the literature of bacteriology. An occasional exception is 
made in favor of some paper appearing in an American periodical which is devoted 
wholly to botany. Reprints are not mentioned unless they differ from the original in 
some important particular. If users of the Index will call the attention of the editor 
to errors or omissions their kindness will be appreciated.
