bas also brought, though from another locality, what seems 
to be genuine S. Fremontii, a much smaller plant than this, 
and with achenes puberulent between the angles. 
S. INVENUSTUS. Stems much branched and apparently 
depressed, only 4 to 6 inches high, clustered on a thick hard 
and distinetly subligneous rootstock, very leafy from the 
base up, and more than usually angular by decurrent lines 
from the leaf-bases: leaves ? to 14 inches long, spatulate- 
oblong, doubly and somewhat laciniately toothed, the teeth 
not callous-tipped, and the whole margin thinly scaberulous 
under a lens, the upper surface showing a few scattered 
hairs: heads 2 to 5, very short-peduncled at the ends of the 
main branches, the lateral branches short, densely leafy, 
flowerless: involueres narrow and subcylindrie, nearly à 
inch high: rays few, about as long as the diameter of the 
head: achenes striate, glabrous. 
Known to me only from 12,000 feet on the mountains 
about Pagosa Peak, Colorado, whereit was obtained by C. F.
