his own shoulders that the burden was lifted. All present also feel that they 
are greatly indebted to the ladies of the Botanical Society, who, through their 
kind and thoughtful attention, did so much to make visiting members feel thor- 
oughly at home. The Botanical Department of the University has also placed 
the Society under great obligations for the courteous loan of the lantern and 
operator, as well as for the use of rooms in the Botanical Hall.

HEPATICAE COLLECTED IN FLORIDA BY SEVERIN RAPP 
[Miss Caroline C. Haynes] 
The following list comprises sixty-four species of Hepaticae collected by Mr. 
Severin Rapp during the years 1903-14. Determinations were made by Dr. A. 
W. Evans and Herr Stephani. The richness of the Southern field is admirably 
demonstrated by the fact that all the specimens yielding these species came 
from one locality, Sanford, Orange Co., or its vicinity. Mr. Rapp is a. good 
collector, his is the keen eye to detect the most minute of species; and while 
there are many rarities and several recently described species, the collection con- 
tains additional material as yet undescribed. 
The numbers correspond with those of a set deposited in the Herbarium of 
the New York Botanical Garden. The list was arranged by Caroline Coventry 
Haynes, who thinks it not out of place to add a plea that botanists while in Flor- 
ida collect hepatics, even though out for bigger game.
