I have also received the plant from Lewis and Ulster Coun- 
ties, N. Y., and have collected it at York Harbor, Maine, the type 
locality, and in the Pocono region of Pennsylvana. 
Type specimens from York Harbor are deposited in the Her- 
baria of Columbia University, and the New York Botanical Garden. 
I take pleasure in naming this species in honor of Dr. N. L. 
Britton. 
To anyone not having given particular attention to our species 
of Agrimonia it is altogether likely that this plant would pass un- 
questioned for A. /irsuta, It has more the general aspect of that 
‘Species than of any other, the large fruit distinguishing it at once 
from A. mollis, with which in some respects it appears to have 
closer affinity. From /irsufa it may be readily distinguished by 
reference alone to its hoary pubescent racemes and darker green 
acuminate leaflets pubescent on the lower surface. It is less 
glandulose and aromatic than /zrsuta and grows to be stouter and 
taller with straighter stem, stouter more ascending branches and 
longer more virgate racemes. The hairiness of the stem is also 
of a different character, being coarser and denser, with shorter, 
stiffer hair. The leaves are commonly narrower and less spread- 
ing, the thicker rugose-veiny leaflets more sharply serrate and 
acuminate with pubescent lower surface bearing brighter glan- 
dules and having the margins ciliolate instead of ciliate-fringed. 
Numerous specimens of /ursu¢a have failed to show any indica-
