largely protective organs against predatory insects. They may 
serve also as a sort of counterpoise in high winds, offering resist- 
ance. 
Conway MacMiian: Nuclear budding in Cypripedium.—The 
speaker had noted a peculiar fragmentation in the nuclei of the 
basal cells of the hairs. The process can be indicated best by 
the term “budding,” as it seems to be a gradual outgrowth from 
the surface of the nucleus with final separation. 
Conway MacMitian: Adaptation of Conifere to wind-swept 
stations.—In his studies of the flora of the Lake of the Woods 
the attention of the speaker had been called to a group of white 
pines which were not growing in the usual manner in rock 
crevices. In addition to the high branches a circle of branches 
flat upon the rocks had been developed, forming a dense circular 
mass, after the manner of a juniper. This was interpreted as all 
adaptation to a high wind-swept position, and shows that “ 
forest plant may assume the juniper habit. 
FLORENCE Beckwitu: Plants new to the flora of Monroe county, 
N. Y.—Since the recent publication of the Catalogue of the 
Rochester Academy of Science several plants new to the flora 
have been discovered. 
Epna M. Porter: Note on the pollination of Epipacts vinidi- 
\ fore —It was shown that the plant is pollinated by the bie 
Vespa diabolica. In Europe, according to Darwin, V. silvesins® 
the pollinator. Plants covered with a netting set no seed. The 
observations were illustrated by an ingenious mechanical chart, 
@ la Gibson. 
E. B. Copetanp: 7; urgor and unused residues.—In all normal 
roots, stems and leaves there is a large residue of osmotically 
active matter which the plant cannot use to postpone starv ar
