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. 

 atte7iuata 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. j^olytrichoides.

 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 Fhyllostachys would be 

 appropriate. In its foliaceous scales it agrees with C. jphyl- 

 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
