Proceedings of the Club. 
The regular meeting was held on Tuesday evening, October 
14th, the President in the chair, and twenty-six persons present. 
Dr. Rusby, chairman of the Instruction Committee, read an 
exhaustive report of the season’s work. In all, fifty-two students 
were enrolled, and the work accomplished was most satisfactory. 
Many reports were given by the members of their observa- 
tions during the summer. The supposed biennial blooming of 
Habenaria ciliaris was again discussed, but the question could 
not be decided from the observations made. 
Dr. Morong reported that he and Mr. Rudkin had been in- 
vestigating the fresh water flowering plants, and that a list of 
forty-seven species had been noted. 
Dr. Rusby exhibited an apple, one side of which showed all 
the markings of the Tompkins King and the other those ofa 
twenty-ounce apple. 
Dr. Britton exhibited from Montana a cactus hitherto 
unknown to that region, and apparently an undescribed species, 
probably allied to a prairie species of Mamillaria. The spines 
are slender, flexible and minutely barbed. For the plant, Dr. 
Britton suggests the name of Mamillaria Notesleint in honor of 
the discoverer. : 
The second October meeting was held on the 29th, the Pres- 
‘ident in the chair, and thirty-four persons present. 
The following were elected active members: Mr. Arthur 
Rolle, Mr. John F. Barnhart, Mr. B. Frank Hays. Prof. Geo. 
F. Atkinson, Prof. B. S. Galloway, Mr. Erwin F. Smith and Prof.

The paper announced for the evening, “Some Botanical 
Gardens of the Old World,” was given by Dr. N. L. Britton.

- Camptosorus rhizophyllus.
