the foot of the snowy range.” This is quite distinct from any Nort 
merican species known to me. Compared with S. frigidus, it is far 
less woolly, even when young, and not at all hairy, except some purple 
hairiness of the involucre; the latter is calyculate with linear scales of 
about Saree the length of the proper involucral scales; and the thin 
. and green leaves are from 3 to 5 inches long, the cauline ones half clasp- 
ing or more by a broad base, not at all inclined to be spatulate. Head 
nearly as bal as in S. frigidus, the rays longer, an inch or more in 
length. Pappus equalling the disk-flowers
