224 - BOTANICAL GAZETTE, [ September, 
four to thirty-six hours before the corolla opens the stigma begins to 
peep out through the center of the convoluted folds. It gradually pro- 
trudes farther until during the last afternoon it is from one-half to three- 
fourths inch beyond the highest point of the closed corolla. It is thus 
ready to be fertilized by the pollen of the flowers that are open the even- 
ing before its own opens. I have examined the other two species of Da- 
tura that grow here, but find no such contrivance for cross-fertilization-

Entertainment of the Botanists in New York.—Nothing that could 
reasonably have been done to add to the profitable enjoyment of the bot- 
anists of the Association during its August meeting was omitted, and the 
execution of the carefully devised plans was accomplished without break. 
This result was brought about by the efforts of the Torrey Botanica 
Club, and thanks are due to no individuals more than to Dr. and Mrs. 
Upon arrival the botanists found a room set apart for the Club, where 
they registered, and received their distinctive badges of yellow silk and 
a programme of the botanical announcements for the week. 
A reception by the Torrey Club was given the Club of the Association 
on Friday evening in the commodious hall of the Columbia Library, 
which afforded a good opportunity for the exchange of courtesies and 
the renewal and promotion of acquaintanceship, A rich collation added 
to the pleasure of the evening. 
No feature of the whole meeting was more enjoyable than the excul- 
oy 4 higher plants, Among lower plants, the abundane ‘ 
hg i orescence of Cyperus Grayi attracted attention; 4 lichet 
rpet- ke growth upon the sandy soil in some places, and @ as 
Geaster stood for the larger fungi.
