1918] PARISH—CALIFORNIA PLANTS 343 
Cottonwood Springs, in the Eagle Mountains, Colorado Desert 
(10854, May 13, 1916), where it was growing along a dry wash, 
and a point on the Colorado River 15 miles east of Searchlight, 
Nevada, where it was abundant and vigorous in the ill-cultivated 
field of a squaw man (10413, June 6, 1915). So far as I have been 
able to ascertain, the stations I have given are all that are known 
for this plant, and in view of their geographical position and of the 
insufficient original description, they throw some doubt on the 
identity of the later specimens with the type. 
ACAMPTOPAPPUS SHOCKLEYI Gray, Proc. Amer. Acad. 7:208. 
1882.—In dry gravelly soil, Harrison Flat (10168) and Emigrant 
Springs (10194), both May 13, 1915. ‘The first of these stations is 
the “Perognathus Flat’’ of the Death Valley Expedition Reports, 
and both are on the Death Valley slope of the Panamint Mountains. 
PsILOSTROPHE CoopEeRI (Gray) Greene, Pitt. 2:176. 1891.— 
This species is so abundant on the mesas at Cima and Leastalk 
(10252, June 1915) that considerable tracts are golden with its 
showy flowers. 
* Dysop1A THURBERI (Gray) Robinson, Proc. Amer. Acad. 49: 
508. 1913.—Quite abundant on a small gravelly bench in the 
Ivanpah Mountains (10241, June 5, 1915), but not seen elsewhere. 
* HYPOCHAERIS GLABRA EROSTRIS Cos. and Germ. Fl. Par.—On 
a dry clay mesa at Upland, Ivan Johnston 77, April 8, 1917. Plants 
slender; stems unbranched or few-branched; leaves obovoid, 
entire or few-toothed; heads few-flowered; achenes all truncate. 
An ecological form of arid soils.
