122 ; PITTONIA. 
closely, deeply and sharply toothed or sometimes almost 
laciniate; cauline elliptic-lanceolate, 2 or 3 inches long 
including the short winged petiole, the margin as in the 
others: heads, usually 3 or 4, large, nodding on erect and 
elongated peduncles : rays to 1 inch long, deep-yellow, 7 
to 9-nerved. 
On stony alpine slopes at 12,000 feet in the mountains of 
Colorado near Pagosa Peak, C. F. Baker, 9 Aug., 1899. It 
in a measure unites the subterranean characteristics and 
tall leafy stem of S. amplectens and the thick foliage of 
S. Holmi, though in point of leaf-outline and indentation, 
and peculiarities of the flower, it has enough characters 
that are all its own. 
S. OCCIDENTALIS. S. Fremontii, var. occidentalis, Gray, 
Bot. Calif. Surv. i. 118. Describing this as a variety the 
author named characters enough to have warranted its 
being placed in specifie rank; but in addition to those 
given at the place cited, I have to say that the achenes, 
puberulent in S. Fremontii,are in this plant of the Sierra 
Nevada perfectly glabrous, and also longer and narrower 
than in S. Fremontii. It is quite possible that other Pacific 
coast plants besides S. occidentalis are to be segregated from 
S. Fremontii as hitherto accepted; and the following from 
the Rocky Mountain region are easily distinguishable 
from it. 
S. CARTHAMOIDES. Stems tufted on a persistent yet 
scarcely more than herbaceous caudex or rootstock, decum- 
bent and nearly leafless below, or the lower leaves at least 
much smailer and more sparse, the whole plant seldom a 
foot high, very leafy above the middle: leaves variously 
obovate and obovate-oblong, commonly 2 inches long or 
more, sessile by a broad somewhat hastate and clasping 
base, the margin coarsely and doubly dentate, the teeth 
callous-tipped: heads } inch high, erect, subcampanulate,
