INDEX TO AMERICAN BOTANICAL LITERATURE 
1916-1917 
The aim of this Index is to include all current botanical literature written by 
Americans, published in America, or based upon American material ; the word Amer- 
ica being used in the broadest sense. 
Reviews, and papers that relate -exclusiv ely to forestry, agriculture, | horticulture, 
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 coihaas will be appreciated.
