VOL. IV.] Flora of Southern California. i6i 



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.
