Hab. North Carolina ! to Arctic America! — Prof. Dewey 
in his critical catalogue of the Carices of the Northern regions 
of America, in Silliman's journal, vol. 28, pronounces C 
attenuata of R. Brown to be a distinct species. We know 
not on what specimens this opinion is founded ; but a speci- 
men from Dr. Richardson under this name, collected at Mac- 
kenzie river, is certainly C. jJolytrichoides.

Hab. Northern and Western States ! to sub-Arctic Ame-

for its peculiar habit, its foliaceous scales, and the distinctly 
articulated base of the style ; it should, perhaps, be placed in 
a separate genus, to which the name Phyllostachys would be 
appropriate. In its foliaceous scales it agrees with C. phyl- 
lostachys of C. A. Meyer, a native of the country adjacent to 
the Caspian sea. The latter species, however, has a continuous 
style, not separating by an articulation from the summit of the 
nut ; and, moreover, we find in our specimen some remarkable 
peculiarities not noticed by the founder of the species, viz : 
the perigynium of the lowest flower encloses the peduncle of a 
separate staminate spike, and the two remaining pistillate flowers 
have within the perigynium, in place of a staminate spike, a
