representatives to C. occidentalis, but differs from both in bearing no glandular hairs. 
Dr. Kellogg’s C. occidentalis nevadensis was subsequently united with his C. occidenta- 
lis subacaulis by Dr. Gray, and with this view of their relation the writer is inclined 
to concur, but a good series of specimens may show that the former belongs rather 
with C. occidentalis. Crepis subacaulis is closely related to C. scopulorum, but it differs 
from that species in its usually lower stature, stem branching more nearly to the 
base with the branches more widely spreading, usually more tomentose leaves and 
stems, commonly broader lobes of the leaf blades, and its costate achenia, which 
are similar to those of Crepis occidentalis, The achenium character appears to con- 
stitute the crucial distinction between the two species. 
SYNONYMY. 
Crepis occidentalis subacaulis Kellogg, Proc. Cal. Acad, v, 50 (1873). Type specimen 
in the Harvard University Herbarium, collected June 27, 1870, by Albert Kellogg and 
S. Brannan, jr., in the Sierra Nevada of California, at the altitude of about 2,100 
meters, near Cisco, Placer County. The specimen is a depauperate one, rising about 
6 em. above the ground and bearing a single anthodium. Besides its rather dense 
tomentum, it bears a few nonglandular bristles on its petioles and stem, The small 
outline figure in plate 23 is a drawing of this type specimen. 
Crepis occidentalis nevadensis Kellogg, Proc. Cal. Acad. v, 50 (1873), Type locality, 
the “summit of the Sierra Nevada,” in California. Type specimen, which appears 
to have been lost, said to have been collected June 16, 1870, in California, ‘at the 
summit of the Sierra Nevada, * * * altitude 7,000 or 8,000 feet (2,183 to 2,468 
meters),” presumably along the line of the Central Pacific Railway. There is a speci- 
men in the Harvard University Herbarium and another in the herbarium of the Cali- 
fornia Academy, dated July 10, 1870, from the Sierra Nevada, presumably collected 
at the type station, and it is probable that these are the specimens upon which, in 
part, Dr. Kellogg based his description. In this specimen the bristles usually present 
in the species are entirely wanting. Jones’s specimens from Nevada County have 
the characters of the original nevadensis. 
Crepis modocensis Greene, Erythea, iii, 48 (1895). Type specimen in the herbarium 
of the Catholic University, Washington, collected in June, 1894, on lava beds, under 
juniper trees, Modoc County, California, by Mrs. R. M. Austin. The plant is doubt- 
fully referred here on account of its pubescence, achenia, and the form of its leaves, 
notwithstanding its large stature, which gives it a general resemblance to C. scopulo- 
rum. These specimens and those of Lemmon from Sierra Valley, in neither of which 
are the achenia mature, render the question of intergradation between this species 
and C, scopulorum uncertain. Both localities are on transition ground geographically, 
and only fuller series of mature specimens can decide the matter.
