yellow; bracts as long or longer than the pappus. I take 

 as the type of this variety my Nos. 5912 and 5847a, and 

 also refer to it No. 6052k and possibly No. 6106k. I also 

 refer Newberry's specimen gathered in McComb's Ex- 

 pedition. Other specimens which belong near here, but 

 with white or whitish stems, are: 



No. 6oo2aa. September 6, 1894, Panguitch Lake, 

 Utah, 8400° alt., in gravel. 



No. 6039b. September 12, 1894, ^^^ Ranch, Utah, 

 in gravel, 7000° alt. 



No. 59891. September 4, 1894, Circle Valley Caiion, 

 in gravel, 7000° alt. 



BiGELoviA Menziesii var. scopulorum. 



No. 5204V. May 10, 1894, near Cedar City, Utah, 

 6000° alt., in gravel (altitude probably too high). 



No. 6074. September 23, 1894, above Springdale, 

 Utah, 4000° alt., on sandy and gravelly slopes. 



This plant is near to B . Menziesii, but is characterized 

 by very long nearly linear, 3 -nerved entire leaves, from 

 2-3' long and 2-4" wide, acuminate at each end; the 

 plants are woody below, very sparingly branched and the 

 branches very long and almost rush-like, erect, and with 

 gradually reduced leaves towards the inflorescence which 

 is corymbose, of few clusters of 3-5 heads; heads yel- 

 low, 5" long, 10 or more flowered; bracts gradually re- 

 duced to minute scales at the base, all being rounded and 

 without distinct, green tips, the inner bracts narrowly ob- 

 long and only a little shorter than the flowers, all glabrous ; 

 fruit linear, hispid; pappus of very delicate white and 

 strongly barbellate, unequal hairs, nearly as long as the 

 flowers; calyx lobes linear, and as long as the anthers; 

 style branches very hispid and long, and stigmatic por- 

 tion short. 



This plant grows on rocks and on rocky hillsides in the 

 canon of the upper Virgen river above Springdale, Utah.
