Dr. Meyer himself, is the densely caespitose comparatively stout Æ. 
callitrix, with depressed-globose heads, and the Altai material might 
easily pass as the basis of the plate accompanying Chamisso's origi- 
nal description. 
That Eriophorum callitrix (in its original sense) was regarded by 
Chamisso and Meyer as specifically distinct from Æ. vaginatum, 
there is no doubt, although the unfortunate mixing of Altai speci- 
mens with the very different stoloniferous noncaespitose Æ. Chamis- 
sonis created a serious confusion. Nylander in his Monograph ' 
recognized the Altai plant as at least varietally separable from Æ. 
vaginatum, and, judging from their description, Trautvetter and 
Meyer have since published it anew as Æ. brachyantherum* from 
northeastern Asia. 
The slender plant taken by Scandinavian botanists as Eriophorum 
callitrix was first described by Björnström in 1856 as Æ. vaginatum, 
var. opacum, but was soon recognized by all European botanists as a 
species distinct from Æ. vaginatum, and they have very generally 
followed the lead of Andersson who supposed it to be Chamisso' 
E. callitrix. This plant (Æ. opacum) has its greatest development in 
the Canadian Rockies, but it extends eastward to the Great Lakes, 
and very locally across Arctic Asia to Spitzbergen and Arctic Scan- 
dinavia.
