INDEX TO AMERICAN BOTANICAL LITERATURE 
1905-1919 
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 being used in the broadest s 
Reviews, and papers that ‘ie exclusiv me to forestry, agriculture, horticulture, 
manufactured products of vegetable origin, or laboratory methods are not included, an 
no o attempt i is made to index the literature of bacterilg. An occasional me is 
made in favor of some paper appearing in an American periodical which is 
wholly to botany. Reprints are not mentioned sorely they differ from the pict in 
some important particular. If users of the Index will call the attention of the editor 
to AETOrs or omissions, their kindness will be appreciated.

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, Corr 
spondence relating to the card i issue should be addressed to the Treasurer of the Torrey 
Botanical Club.
