obtained by him on Mt. Bill Williams, which have some 
resemblance to RX. Caltfornica, but I do not venture to pronounce 
with certainty as to their specific identity. It is very likely, 
from the known facts, that R. Californica is a species entirely 
western, peculiar to California, and having the Sierra Nevada as ‘ , 
its eastern limit. : 
If one should believe Mr. Holzinger (oc. cit.) the limit of 
this species should be extended to Idaho, but no. 173 of the — 
Sandberg collections, reported by that author as R. Californica, is — 
R. Nutkana, while no. 871 certainly does not belong to &. Cali- 
fornica. The specimen which I have received is a vigorous 
flowering branchlet, with inflorescence 22-flowered. Despite 
this many-flowered inflorescence and quite a small corolla I am 
inclined to believe that this specimen is a variety of R. Nutkana. 
In his Flora of California Watson describes a variety of X. 
Californica under the name wltramontana. This is passed over in 
silence in the monograph of the same author, and I do not 
possess authentic specimens of it. Mr. Jones has distributed, 
under no. 2455, with the name R&. Californica var. ultramontana 
Watson, specimens of a form obtained at Salt Lake City, which 
reasonably agrees with the description of the variety wtramontand, 
but which does not appear in any way to belong to R. Californica. 
It rather seems to be a variety of R. pisocarpa. 
ROSA SPITHAMA Watson. 
R. spithamea was established by Watson in 1880, in his Alora 
of California, Later, in his monograph, he did not maintain the = 
species, but reduced it to a variety of R. Californica. Perhaps’ 
Watson was influenced by the opinion which I had expressed 
concerning its establishment as a species.” Since 1882 I have 
received some new specimens of that curious rose, and their 
examination has induced me to think that it can very well be 
specifically distinct from R. Californica. In the valley of the 
Trinity river, where Mr. Rattan first discovered it, it 1s €X-
