C. Arthur for a continuation of his study of 

 Uredineae. 



As a result of long continued conferences 

 between committees of the Botanical Society 

 of America, the Society for Plant Morphol- 

 ogy and Physiology and the American 

 Mycological Society, and in connection with 

 similar action on the part of the other 

 bodies named, the society adopted a new 

 constitution by which the three societies are 

 federated under the name The Botanical 

 Society of America, details of the federation 

 under the new constitution being placed in 

 the hands of the ofScers. 



The following papers were presented :

 Vus impudicus (L.) Fries, from France.'

 photographs of European fleshy fungi, 

 made by Professor Atkinson by the aid of a 

 grant made at an earlier meeting of the 

 society.

THE ASSOCIATION OP AMERICAN 

 GEOGRAPHERS. 



The second annual meeting of the Asso- 

 ciation of American Geographers was held 

 in New York City, December 26-27, 1905, 

 under the presidency of Professor ^. M. 

 Davis, of Harvard University. The Ameri- 

 can Geographical Society generously 

 oifered the use of its house, at No. 15 West 

 Eighty-first Street, and served luncheon to 

 the members present on both days of the 

 meeting. The annual dinner was held at 

 the Hotel Endicott on the evening of De- 

 cember 26. It will appear from the pro- 

 gram as given below that the several phases 

 of geography, particularly the organic, 

 physiographic and educational, were well 

 represented. All the papers here named 

 were read by their authors, and others were 

 read by title. About forty members and 

 invited speakers were present.
