on the involucral bracts, together with its more scapose character and the thickness 
of its peduncles, serve to distinguish it from C. scopulorum. It may yet be found 
that intergradation occurs. 
SYNONYMY. 
Crepis occidentalis crinita Gray, Bot. Cal. i, 435 (1876), not Crepis crinita Solander 
(1831). Type specimen in the Harvard University Herbarium, collected in the year 
1841, on the eastern side of the Cascade Mountains, between the Natches (Spipen) 
and Wenatchee rivers, by the botanists of the Wilkes Expedition. In the type 
specimen the involucral hairs are unusually dense, and from lying long on herbarium 
shelves have changed from a mi!k-white to a dirty yellow color, while the achenia, 
although beaked, do not show that character so conspicuously as do the mature 
specimens now collected.

CREPIS BARBIGERA Leiberg, sp. nov, 
Plant perennial, stout, 40 to 50 cm. high, minutely viscid-pubescent when living, 
appearing slightly tomentose when dry ; basal Jeaves usually ample, with long peti- 
oles, their blades 15 to 30 cm, long, oblong-lanceolate in outline, runcinately toothed 
to pinnatifid, but seldom deeply parted ; cauline leaves mostly small and few, vari- 
ously pinnatifid or the uppermost even entire; anthodia commonly 10 to 20, fastigi- 
ately corymbose; involucre 11 to 15 mm, long, sparingly tomentose, resiniferous; 
bracts strongly carinately costate from base to apex, the costa setosely barbate with 
one or two rows of long, stout, yellow or yellowish green, divaricate or even slightly 
retlexed bristles; corollas more or less deeply and very irregularly five-toothed ; 
achenia acutely 10- to 12-costate, 8 to 10 mm. long, tapering upward, dilated at the 
apex, olive-green in color when near maturity; pappus rather copious, somewhat 
shorter than the achenium. PLATE XXVI. 
Type specimen in the United States National Herbarium, collected June 25, 1898, 
near Alkali Lake, Douglas County, Washington, at an altitude of 400 meters, by 
J. H. Sandberg and John B. Leiberg (No. 313). 
This species is a much larger and more robust plant than Crepis occidentalis, and 
is easily distinguishable from it, in addition to other characters, by the conspicuous 
nonglandular bristles of the involucre and the scant tomentum of the leaves. It 
has usually been distributed as C. occidentalis erinita. In some of Howell’s specimens 
from eastern Oregon the bristles of the involucral bracts are almost wanting, and 
the plant then bears a close general resemblance to Crepis intermedia.
