Index to recent Literature relating to American Botany 



This Index is intended to include (i) Titles of all papers and 

 books relating to American plants ; (2) All papers on botanical 

 subjects by American botanists ; (3) Papers of special interest re- 

 lating to physiological or morphological subjects wherever pub- 

 lished. Botanists can aid greatly in this matter by the contri- 

 bution of separates of their papers especially those published 

 outside the usual botanical journals, such as the publications of 

 learned societies, experiment station bulletins and reports, and 

 journals only occasionally containing botanical matter. 



The titles are reprinted monthly on standard library cards of two 

 widths, and are sold to subscribers at the price of one cent per card. 



The editors will welcome any notice of omitted titles or other 

 suggestions relative to the greater efficiency of the Index. Ad- 

 dress all matters relating to the Index to The Torrey Botanical 

 Club, Columbia University, New York City.
