VOL. Iv. | Flora of Southern California. 161 
Some of these extensions have been noted in the last volume 
of the Synoptical Flora, or in recent monographs and other 
papers. A considerable number, however, remain as yet 
unrecorded, and some of the more interesting of these are given 
in the following list, which makes no pretense to completeness, 
and, indeed, might easily be considerably enlarged. The place 
of publication is cited for these species not enumerated in the 
Botany of the Survey, and these are additions to the flora of the 
State, as well as to that of Southern California. The others 
extend the range of more northern plants not heretofore recorded 
from the southern counties. With the exception of a few rare 
species none of those are included whose previously known range 
was south of the latitude of San Francisco. 
Phytographically these northern plants belong to the Sierra 
Nevadan flora, and they form most of the additions to the vege- 
tation of our higher mountains. The Sonoran flora of the arid 
regions to the east, Nevada, Arizona, Utah, has supplied the addi- 
tional desert plants, and some of those which climb the desert 
flanks of the mountains. The stations for the first class are in 
many cases the southern limit of the species, and those for the 
second class the western or northern limit. Some exceptional 
plants will be noticed by the reader. All stations recorded are 
authenticated by specimens in the herbarium of the writer, and 
when no other collector’s name is cited his is to be understood.
