PROCEEDINGS OF THE CLUB 29 



Frank (unpublished) has demonstrated the presence of a pigment with an absorption 

 spectrum somewhat similar to chlorophyll, which is responsible for chlorophyll formation. 

 It is not impossible that this pigment may also be involved in the inhibition of the inter- 

 node, since it absorbs strongly in the red, a property not shared with the carotinoids. 



After considerable discussion of Dr. Goodwin's interesting presentation, 

 the meeting was adjourned at 4:35 p.m., but continued informally, with enjoy- 

 ment of the refreshments generously provided by The New York Botanical 

 Garden. 



Respectfully submitted,

Minutes of the Meeting of December 20, 1944 



The meeting of the Torrey Botanical Club at The New York Botanical 

 Garden was called to order at 3 :30 p.m. by President Levine, with twenty-five 

 members and guests in attendance. The minutes of the preceding meeting were 

 accepted as read. The President appointed a committee consisting of Drs. 

 Karling and Matzke to count the ballots for the election of officers for 1945. An 

 auditing committee consisting of Professor Trelease, Chairman, Mr. Mon- 

 tagne, and Dr. Seaver was appointed by Dr. Levine to audit the books for the 

 year 1944. 



The scientific program consisted of an interesting talk by Prof. Ray F. 

 Dawson of Princeton University on "Some Aspects of Alkaloid Production in 

 Cinchona/' The speaker's abstract follows : 



A population of Philippine Cinchona "Ledgeriana" was found to be of hybrid origin. 

 Plants bearing the morphological characteristics to be expected of haploids, diploids, 

 tetraploids, and octoploids have been obtained from this population. Of these, the "tetra- 

 ploid" is the most vigorous in growth. ,
