—Mr. Meehan called attention to the fact that in England the 
male flowers of the hazelnut had been perfected this year before 
any sign of the female flowers appeared. This was in accordance 
with his observations in this State. Mr. Canby remarked upon an 
exudation of moisture from the tips of the leaflets in Akebia 
quinata. An examination by Professor Rothrock disclosed an 
arrangement of the tissue at the apex of each leaflet, evidently 
adapted to such an exudation. Mr. Meehan said that the liquid 
globules of this plant appeared indifferently in the day or even- 
ing, in dry or moist weather. Mahonia aquifolia had on its flower 
buds, similar globules, which collected until they formed drops as 
rge as peas among the dense head of flowers. An exudation 
Occurs also in coniferz, and probably the pollen grain is carried 
to the nucleus as the moisture is absorbed within the vesicle. 
r. Meehan also exhibited a series of cones from different trees 
of Pinus rigida, showing a change of forms from the typical P. 
rigida to a cone that could scarcely be distinguished from P. 
a. .
