Hall. Compositae of Southern California. 83 



tended by a few linear bracts or naked ; involucral bracts linear, 

 acute, loosely imbricated in about 3 series, strongly ciliate but 

 otherwise glabrous, green and herbaceous throughout except for 

 a very narrow white or reddish margin : rays 25 to 35, 10 to 15 

 mm. long, 2 mm. broad: achenes strigose-pubescent : pappus 

 tawny. (Plate 3.) 



Open marshy meadow at an altitude of 1980 m., on a tributary 

 of Mill Creek, about 6 kilometers northeast of Tyler's Retreat, 

 San Bernardino Mts., California, Aug. 30, 1904, Dr. R. J. Smith, 

 no. 76. 



The collector writes as follows : ' ' As I remember the plants 

 they were from 8 to 14 inches high, mostly simple with a single 

 terminal head, but others had 4 or 5 heads. They grew quite 

 freely in this one locality but I have not seen them elsewhere." 

 This species is apparently related to both A. Fremonti Gray and 

 A. occidentalis Nutt. Further collections may reveal inter- 

 mediate forms connecting it to one of them, but at present it 

 may be distinguished by the large sheathing lower leaves and 

 the larger heads with longer rays. The type is in the Herbarium 

 of the University of California.
