This essentially alpine plant is characterized by the en- 
larged caudices, dense rosettes, and short stems. In fruit char- 
acters it is very similar to L. occidentalis and might with pro- 
priety be considered varietally under that species. The two 
plants are rather easily separated, and since their ranges also 
seem not to merge it was thought advisable to retain the original 
treatment.
