SECTION G— BOTANICAL SCIENCES AND 

 ASSOCIATED SOCIETIES 



Section G held its session on Wednesday 

 afternoon, December 28, 1921, in conjunction 

 with the Botanical Society of America and the 

 American Phytopathological Society. There 

 was a large attendance at this meeting, and the 

 symposium, thotigh involving several papers, 

 was not unduly long. Professor Rodney H. 

 True, retiring vice-president for Section G, 

 delivered his address on "The physiological 

 significance of calcium for higher green plants," 

 which has been published in Science, Vol. LV, 

 p. 1, January 6, 1922. The vice-presidential 

 address was followed by a symposium on "The 

 Species Concept," at which the following 

 papers were read: (1) "From the viewpoint 

 of the systematist," Charles F. Millspaugh ; 

 (2) "Prom the viewpoint of the geneticist," 

 George H. ShuU; (3) "From the viewpoint of 

 the morphologist," R. A. Harper; (4) "From 

 the viewpoint of the bacteriologist and physi- 

 ologist," Guilford B. Reed; (5) "From the 

 viewpoint of the pathologist," E. C. Stakman. 

 The writers of these papers cooperated splen- 

 didly, both in division of subject matter and 

 in time of presentation. The results seem to 

 confirm the expressed belief of many botanists 



that a symposium of general interest, making 

 appeal to workers in all the principal fields, 

 is well worth while. 



At the business session of Section G, John 

 T. Buchholz, of the University of Arkansas, 

 was elected to be a member of the section com- 

 mittee, his term of office to end Januarj' 1, 

 1926. Professor F. E. Lloyd of McGill Uni- 

 versity, was selected as vice-president for Sec- 

 tion G for 1922.
