INDEX TO AMERICAN BOTANICAL LITERATURE 
1923 
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 
America being used in the broadest sense. 
Reviews, and papers that relate exclusively to forestry, agriculture, horti- 
culture, oe products of \eertenee ongin, or ee ratory methods 
nd iterature of bacteriology. 
An occasional ie is made i in favor of some paper appearing in an Ameri- 
can 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 three cents for each card. Selections of cards are 
not permitted; each subscriber must take all cards published during the term 
of his subscription. Correspondence relating to the card issue should be 
addressed to the Treasurer of the Torrey Botanical Club.
