Dr. Robbins moved that Dr. Barnhart be delegated to repre- 

 sent the Torrey Botanical Club at the celebration of the 50th 

 Anniversary of the foundation of the Philadelphia Botanical Society 

 in Philadelphia on Friday, December 18, 1941. The motion was 

 seconded by Dr. Dodge and passed by the Club. 



The scientific part of the program consisted of a talk and 

 demonstration on "Vitamins and growth of plants" by Dr. W. J. 

 Robbins of the New York Botanical Garden. The speaker's 

 abstract follows : 



It is now well established that the growth of many fungi is limited 

 by their inability to make adequate quantities of one or more vitamins. 

 Such fungi do not grow or grow poorly in a medium limited to pure sugars, 

 minerals and asparagine but on the addition of various substances of natural 

 origin or of one or more chemically pure vitamins, they develop satisfac- 

 torily. Ten species or strains of Ccratostomella were investigated. 



The CerastostoincUas I used may be grown readily in media to which 

 various natural products have been added, for example, malt agar, media 

 containing a decoction of tree bark, and so on. However, of the ten strains 

 or species reported here one only makes any considerable growth in a 

 medium limited to minerals, sugar and asparagine. This is Ceratosfomclla 

 pseudotsugae. However, the addition of vitamin Bi and of vitamin Be to 

 the medium materially increases the growth of that fungus. Biotin has no 

 effect. C. pseudotsugae shows a partial deficiency primarily for vitamin Bi
