Intermediate between Arnica alpina (L.) Olin & Ladan of the Arctic 
and of northern Labrador and A. tomentosa J. M. Macoun of the 
Canadian Rocky Mountains. In A. alpina, which A. pulchella re- 
sembles in the shape and the tips of the leaves, the pubescence of the 
leaves and the lower half of the stem is very sparse and short, the 
involucre consists of 15-20 narrower less pubescent bracts; and the 
narrower rays are much less cleft, the blunter lobes being 1-2 mm. long. 
In the northwestern A. tomentosa the basal leaves are thicker than in 
A. pulchella, more prominently nerved and blunter, and covered with 
much longer pubescence; the upper leaves lack the slender apical 
appendage which is present in’ well developed A. pulchella; the pubes- 
cence of the stem and the involucre is very much longer and more 
copious (almost lanate); the bracts of the involucre are bluntish or 
merely acute; and the thicker and less prominently nerved rays have 
a longer pubescence on the back.
