and Carboniferous, and on the characters and affinities of the 

 Paleozoic gymn os ferms, by Sir William Dawson. 



The paper was based upon material recently discovered. 

 Stem, leaves and fruit from the Erian of Pennsylvania serve 

 to establish a new genus and species, Dictyocordaites Lacoi, 

 and other unusually perfect material from the same State and 

 from Prince Edward island enable the author to clear up sev- 

 eral obscure points in relationship. 



The Botanical Club of the A. A. A. S. 



It has been the custom of the club from its inception, with 

 possibly an interruption at the Cleveland meeting, to hold its 

 first session on Thursday, the second day of the association.

 self-fertilization of the common garden pea, and of the failure 

 of the English bean (Faba vulgaris) to produce many pods 

 in American gardens, although flowering freely. Mr. David 

 b . Day had observed that the rose acacia (Robinia hispida) 

 bloomed freely about Buffalo, N. Y., but set few pods, and 

 examination had shown little pollen in the anthers. He also 

 stated that the garden variety of (Enothera biennis expands

 b . V. Coville said that Lupinus perennis also discharges pollen 

 in the bud, but that in this case the stigma is not at the time 

 in a receptive condition. Dr. B. 1). Hals ted, in his exami- 

 nations of the garden pea, had found no germinating pollen
