INDEX TO AMERICAN BOTANICAL LITERATURE 



(1909)"^ 



The aim of this Index is to include all current botanical literature written bj' 

 Americans, publisbed in America, or based upon American material ; the word Amer- 

 ica being used in its broadest sense- 

 Reviews, and papers which relate 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 Icindness 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 terra of his subscription. Corre- 

 spondence relating to the card-issue should be addressed to theTi%asurer of the Torrey 

 Botanical Club.
