The meeting of February 26, 1913, was held in the laboratory 

 of the New York Botanical Garden at 3 :30 P.M. Vice-president 

 Barnhart presided. Thirteen persons were present. 



The minutes of January 29 and February 11 were read and 

 approved. 



The following were elected to membership: Mr. James Kelly, 

 2163 Gleason Avenue, New York City; Mr. Francis W. Pennell, 

 Wawa, Pennsylvania; Mr. J. K. Henry, 2024 Beach Avenue, 

 Vancouver, B. C; and Amji di Lignari, 549 West 113 Street, 

 New York City. 



The scientific program consisted of a paper by Dr. E. W. Olive 

 on "The Life History of the Rusts." 



Four types of development were recognized, (i) Micro and 

 Lepto, (2) Brachy, (3) Opsis, (4) Eu or complete forms. Dr. 

 Olive holds to the view that the simpler micro and lepto types 

 consisting of pycnidia and teleuto only are the more primitive, 

 from the standpoint of development, and that the so-called 

 repeating spores, the aecidio and uredo have been intercalated 

 between these. The origin of heteroecism was briefly discussed.
