BIBLIOGRAPHY OF AMEKKVVX BOTAXY. 



The Bibliography Committee of American 

 botanists has just completed its first year of 

 organized work in the production of an 

 author catalogue of papers relating to 

 American Botany. This has been printed 

 in the monthly issues of the Bulletin of the 

 Torreij Bot<niie(iI Club and then reprinted on 

 library cards by the Cambridge Botanical 

 Supplj- Co. The editors have endeavored 

 to make the record as complete as possible 

 and it includes 57-5 titles. The commit- 

 tee and the editors earnestlj- request that 

 their attention be called to omissions and 

 that all interested aid in insuring complete- 

 ness. 



Foreign botanists are particularly re- 

 quested to call our attention to any of their 

 writings which refer to American plants. 

 Communications may be addressed to the 

 Editor of the Torrey Botanical Club, Co- 

 lumbia College, New York City.
