hermaphrodite ; the others all dioecious, not polygamous. The 

 plant that is growing in Europe, supposed to have been introduced 

 from America, and described as AiiacJiaris Alsinastnivi Babing- 

 ton, resembles E. canadensis in habit, but only pistillate flowers 

 have been found, and in these the stigmas are entire. In the 

 North American forms with dioecious flowers the staminate 

 sheaths are sessile in the axils of the leaves and easily over- 

 looked, except in the plant common in the Rocky Mountain re- 

 gion and one specimen from Tennessee, in which the sheaths are 

 peduncled. In the Rocky Mountain plant the staminate flowers 

 are apetalous. 



The subject will be more fully discussed in a paper which Dr. 

 Rydberg is preparing to publish in the Bulletin of the Club, as 

 soon as more material has been consulted and certain questions 

 can be answered more definitely. 



Both papers were briefly discussed and adjournment was at
