INDEX TO AMERICAN BOTANICAL LITERATURE 
1908-1919 
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 set used in the broadest sense. 
Rev , and papers that ee exclusively to forestry, agriculture, horticulture, 
manfatored products of vegetable origin, or laboratory methods are not included, and 
o 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. 
This Index is reprinted monthly on cards, and furnished in this form to subscribers 
at the rate of one cent for each card. Selections of cards are not permitted ; each 
subscriber must take all cards published during the term of his subscription. Corre- 
spondence relating to the card issue should be addressed to the Treasurer of the Torrey
