ing toward the base scattered eglandulose bristles; leaves similar in pubescence to 
the stem, the blades cleft almost to the midrib, the divisions Jinear-lanceolate and 
sharply toothed or lobed; peduncles slender, usually thicker just beneath th» 
anthodium; involucre 10 to 12 mm. high, scantily tomentose, bearing a few greenish 
black or green eglandulose hairs usually 2 to 3 mm. long; achenia 7 to 9 mm, long, 
fusiform, truncate at the apex, olive-green or sometimes reddish brown in color at 
maturity, not costate but sometimes marked with lines of paler color in place of 
cost. PLATE XXIV. 
Type specimen in the United States National Herbarium, collected August 16, 1893, 
in the Yellowstone National Park, by J. N. Rose. 
This plant is distinguishable from Crepis occidentalis by its uniformly deeply cut 
glabrescent leaves, the eglandulose bristly hairs of its stem and involucral bracts, 
and its noncostate achenia, Red achenia have been seen only in Hillman’s speci- 
mens from Reno, Nevada. ,

CREPIS ROSTRATA Coville, sp. nov. 
Plant perennial, 15 to 30 cm. high, with one to three stems from each caudex; 
stems striate-angulate, with little or no tomentum, sparingly hirsute, especially 
below, with glandless hairs; leaves with similar pubescence (the bristles often con- 
fined to the midrib and petioles), their blades deeply pinnatifid into linear-lance- 
olate, toothed or pinnatifid divisions; anthodia one to three on each stem, on long, 
stout peduncles, these slightly contracted just beneath the anthodium,; involucre 12 
to 15 mm. high, devoid of tomentum (except in some cases at the very base), either 
densely clothed or only scantily provided with long glandless hairs (of a milk-white 
color in our freshly dried specimens); achenia 7 to 11 mm. long, not costate, olive- 
green at maturity and usually marked with lines of fainter color, the upper part 
contracted into a distinct beak 2 to 3 mm. long. PLATE XXYV. 
Type specimen in the United States National Herbarium, collected June 18, 1893, 
near Crab Creek, Douglas County, Washington, at the altitude of about 750 meters, 
by J. H. Sandberg and J. B. Leiberg. 
This plant differs from C. occidentalis in the same characters as those given under 
C. scopulorum, and is a close relative of that species. Its conspicuously beaked ache- 
nia, the milk-white color of the involucral hairs, and the usual absence of tomentum
