Will the members interested in the hepatics help the Curator during 1915 
to acquire as complete a representation of North American species as possible?' 
Few realize that the Herbarium still lacks no of the species listed in the So- 
ciety “Exchange List.” Some of the species, it is true, are rare and known only 
from a single collection, like Jungermannia danicola and J. Bolanderi, but surely 
there are many on the list given below of species desired, which could be found 
anew, or specimens already .possessed could be divided and given to the Her- 
barium. Some of these species are represented in the Herbarium by European 
material, but none from North America. This is a real need. The following 
species are desired: 
Riccia albida, R. californica, R. Campbelliana , R. Catalinae , R. dictyospora, 
R. hirta , Corsinia marchantioides, Sauteria alpina, Plagiochasma Wrightii, Grim -

Report of the Lichen Department for 1914 
The prosperity in this department set forth in the reports of former cura- 
tors has happily not abated during the past year, due to generous contributions 
of material received from various members. Prof. O. E. Jennings sent valuable 
specimens from Ontario, Canada, collected by himself, Grace K. Jennings, and
