This species forms no small part of the talus vegetation in the 

 Canadian and Hudsonian zones, in places covering the slopes so 

 thickly as to form a kind of dwarf chaparral. 



Agastache urticifoUa (Benth.) Rydb. (Mem. Dept. Bot. Columbia 

 Univ., vol. 2, p. 359. 1900), a common Transition species of rich moist 

 ravines and meadows, occasionally rises above our lower limits (Char- 

 ity Valley, Alpine County, 8,000 feet, Hansen 437 ; Snow Creek trail 

 to Lake Tenaj'a, Yosemite, 7,100 feet. Smiley 664). 



Ckamesaracha nama- Gray (Proc. Am. Acad., vol. 10, p. 62), a 

 nearly acculescent tufted perennial species peculiar to California and 

 the Tahoe region of Nevada and belonging to a genus confined to the 

 arid southwest from Texas to California, occurs in the Transition 

 and rarely above in the Sierra north to Mt. Shasta (Mt. Rose, 9,000 

 feet, Kennedy 1720).
