ate growth of branches, and thus obviate the useless expenditure 
of energy displayed by trees whose branches are always killed 
back by winter frosts. All the time which elapses between the 
formation of terminal scaly buds, or the casting off of the tips of 
branches, and the first frosts of autumn, may be looked upon as 
a period of preparation for the few weeks of active growth of the 
next season. 
The Hepatice of Labrador, 
By Lucien M. UNDERWOOD. 
During the past three years Rev. Arthur E. Waghorne, 
of Newfoundland, has been sending large numbers of packets of 
Newfoundland Hepaticee for examination, and has made a large 
number of additions to the only published list* from that prov- 
ince. The examination of this series had been interrupted, and 
a full report of the Newfoundland species cannot yet be given ; 
this will follow later, 
During August of last year (1891) Mr. Waghorne took a short 
trip to the coast of Labrador, and as one of the results has sent 
over a hundred packets of liverworts for determination. With 
the exception of a few species from this coast sent me by Mr. O. 
D. Allen in 1887, these are the only ones yet reported from that 
region. While the list contains mostly species that would be ex- 
pected from this locality, one or two species are of interest as 
having no definite location to which they could be assigned. 
This is particularly true of Harpanthus Flotovianus, which was 
described in the revised Manual as “certainly extra-limital” 
without my knowledge or approval. I have reason to believe it 
will be found in our Northern States, particularly in mountain 
regions, 
T append the list as follows :
