136 



species were recorded at this season of the year. The Hst is filed 



with the field committee and it is hoped that additions may be made 



as others visit the trail in this area at different seasons. We have 



previously recorded some thirty Hchen species, inchiding forms of 



Cladonia species. , . ^

Trip of April 17 to Boyce Thompson Institute for Plant 



Research 



Approximately thirty people arrived at the Institute at 2 o'clock. 

 We spent from 2 to 4 going through the building and the green- 

 houses. We discussed a few projects in some detail and talked in 

 general about the work at the Institute. While visiting my labora- 

 tory the group was given a demonstration of formative effects of 

 B-naphthoxy acetic acid and samples of seedless tomatoes which 

 were induced by this compound. In another laboratory they saw 

 potato chips and learned that variation in color of the potato chips 

 is usually associated with variation in content of reducing sugars. 

 Members of the party came from Pennsylvania, New Jersey, and 

 New York. The University of Pennsylvania was represented by 

 Dr. E. T. Wherry and several members of the graduate school. The 

 New Jersey College for Women was represented by Dr. Small and 

 several others from Rutgers University. Dr. Trelease came with 

 a group from Columbia University. The field committee was repre- 

 sented by Dr. James Murphy and several other members. Though 

 the names were not recorded, the rest of the group was made up 

 of members and associate members of the Torrey Botanical Club.

Trip of April 27 to Bushkill Falls, Pa. 



More than thirty members of the Torrey Botanical Club gath- 

 ered at Bushkill Falls on Sunday morning, April 27, to study the 

 flora, especially the bryophytes, and to make comparisons with the 

 data that have been assembled in this locality during the past several 

 years (Torreya 40: 175-177). Mr. Nearing contributed much by 

 discussing the lichens, some of which are not generally found, and 

 Dr. Higinbotham identified many of the more puzzling mosses. 

 Most of the genera and species of the bryophytes examined had 

 been collected here in previous years, though we had not noticed
