Hab. Melville Island, Arctic America, Capt. Parry ; 
Kolzebue's Sound, Capt. Bccchcy ; Greenland, Capt. Sabine. 
A native also of the northern parts and high mountains of 
Europe. 
Obs. I have seen no North American specimens of this 
plant, which it is very difficult to distirguish from E. vagina- 
turn, except by the shorter anthers and hairs. 
The IB. calUthrix of Chamisso, described at full length and 
figured in the work quoted above, was found on the Island of 
St. Lawrence, near Behring's Strait. Except in the leaves 
being scabrous, it appears to differ so little from E. vagifiatum, 
that it can hardly be regarded as a distinct species. 
4. Eriophoru-m Chamissoxis, C. A. Meyer. 
Culms solitary, terete, smooth; leaves compressed, smooth; 
sheathes somewhat inflated ; spike oblong ; antliers linear.

of Altai, Chamisso. 
Obs. I have not seen this plant, but it appears to be scarcely 
distinct from E. vas^inatian.
