CONTRIBUTIONS TO THE KNOWLEDGE OF WEST 
AMERICAN PLANTS. I. 
‘ 
KATHARINE BRANDEGEE, 
CAMELINA SATIVA Crantz is abundant in fields and by the way- 
side near the Klamath River, in Siskiyou County. 
PARONYCHIA CHILENSIS DC. Abundant in the western part 
of this city, from the Presidio at least as far as the southern end of. 
Lake Merced. It was apparently first observed by Professor E. L. 
Greene, the earliest specimen in the Herbarium being labeled in 
his handwriting, ‘‘ Presidio, San Francisco, April 21, 1887; E. L. 
Greene.” It agrees perfectly with a specimen sent by Dr. Philippi 
— from Chili, but not very well, with De Candolle’s description, the 
calyx lobes more like those of P. Bonariensis. Possibly they are 
variations of the same species. 
Ceanothus rugosus Greene, Flora Franciscana, 88. The really 
astonishing thing about this is, not that the author has applied a 
specific name to a plant which is * doubtless a hybrid’’ but that 
he from ‘‘his vantage ground of familiar knowledge ”’ of our plants 
‘should be ignorant of the fact that neither C. cuneatus nor any 
other species of the Cerastes section, excepting C. prostratus, is 
to be found within thirty miles of Truckee. 
MEDICAGO MARGINATA Willd. Almost as common about San 
Francisco, especially about the Marine Hospital and South San 
Francisco, as M/. denticulata. It abounds also in places about 
Tamalpais and has been reported from Sonoma by Frank H. Vaslit. 
Mepicaco MmaAcuLaTa Willd. Occasionally met with about 
_ Tamalpais. 
Hrucuera PILosissIMA Fisch. & Meyer, grows on the hills west 
of Noe Valley in an unusually stout, erect form. ; : 
~ SCANDIX PECTEN-VENERIS L. is extremely abundant in grain 
fields and by the waysides in the western part of Contra Costa 
County and in the streets of Oakland. 
- VALERIANELLA OLITORIA Poll. cultivated under the name “Dou- 
cette ” has been recently collected by Miss E. Cannon, on the sand- 
hills in the western part of the city. It has been previously re- 
ported from Sweetwater, El Dorado County. 
_ HELIANTHELLA CALIFORNICA Gray, has been collected this 
season by F rank H. Vaslit, on hills east of Ocean View in this city.
