York City.” The paper was illustrated by a large number of lan- 
tern slides made and colored from nature, the beauty of which 
elicited many expressions of admiration from the audience. The 
paper was discussed by the Secretary, who expressed the hope 
that those present would follow up their acquaintance with our 
wild flowers made from the lantern slides, by a personal acquaint- 
ance made in the field during the coming season, in connection 
with the excursions of the Cluband of the summer class in botany. 
Dr. Britton called attention to the scientific features of such ac- 
curate illustrations, by which he had noted that a rare species of 
Asclepias, A. decumbens, not previously reported from this locality, 
occurred in the vicinity of New York. He also mentioned the 
strong contrast between the lowland and mountain forms of Ee 
patorium purpureum as endorsing his view that they were distinct 
species. 
Dr. Britton called attention to two important publications, viz., 
1, American Algae, Century 1, 1894, by Miss Josephine E. Tilden, 
of the University of Minnesota; 2, Phycotheca boreali-Ameri- 
canae, fascicle 1, by Messrs. Collins, Holden and Setchell.
