Upper Sonoran Zone on the coastal slope : first collected ne;ir 

 Newhall by Nevin; crevices of cliffs, San Francisquito Canon, 

 ace. to Parish; Santa Monica Range, above Sherman, Braunton, 

 no. 517, and Greata, no. 331 ; near Pasadena, ace. to McClatchie ; 

 San Antonio Canon, near Claremont, Baker, no. 3731 ("in low 

 dense tufts on a woody base, occasional along stony bottom of 

 wash"). 



Writing of the station above Sherman Mr. Braunton says: 

 "It must have been introduced at this station within the past 

 few years. In 1901 there were but few large plants and many 

 small ones. Now (1902) it is common for a mile square and 

 bids fair to extend everywhere in the hills. ' '
