Prof. Wettstein tbinks it probable tbat tbis species bas a wider 

 range tbrougbout Arctic Europe, Asia and America. 



Specimens from Greenland and Cumberlandaremostly glandular, 

 tbose from otlier localities are mostly eglandular. Some specimens 

 from Lapland differ considerably from tbe type. E. latifolia is a 

 somewbat polymorpbic species, as would be expected from its wider 

 range. Robust forms have densely imbricated, broad and coarse 

 teetb, but these characters are not so evident in slenderer forms. 

 E. Tatarica and E. curta are the most nearly allied species, and the 

 areas of these species touch that of E. latifolia. From tbe former 

 it may be distinguished by the imbricated and non-aristate bracts, 

 and the presence, usually, of glandular pubescence ; from the latter, 

 by the less abundant but coarser pubescence, large flowers, blunter 

 and more distant teeth, also by its fewer stem leaves ; from E. 

 Foulaensis by its more hairy and smaller, sharply toothed bracts : 

 the teeth being also more patent, and by its more hairy calyx. 



I had two specimens gathered by the Rev. E. S. Marshall 

 in 1896 on cliffs west of Melvicb, Sutherland, which I sent to 

 Prof. Wettstein for his opinion respecting them, and he wrote 

 on the ticket, '''i E. latifolia Pursh." The plants are a little
