Jime 29, 1909; and I take pleasure in naming it for its discov- 

 erer, the able teacher and enthusiastic collector, Professor Els- 

 worth Bethel, of the East Denver High School. 



Aster laevis strictiflora var. nov. 



Strict and upright, S to 12 dm. high, all the leaves narrowly 

 linear, the lower about 12 cm. long, 6 to 8 mm. wide, the blade 

 only slightly differing from the winged petiole, and sessile by a 

 broad but scarcely clasping base, the upper similar but smaller 

 and with more clasping bases: the inflorescence slightly pan- 

 icled, the branches upright and strict: the flower heads 6 to 7 

 mm. high: the coriaceous bracts green for half their length. 



Differing from Aster laevis L. in the narrow, linear leaves 

 and the greener bracts of the flower heads. Collected at Glen- 

 wood Springs, Garfield county, Colorado, August 18, 1906, no. 

 3397- 



Arnica Parryi crinita var. nov. 



About 3 dm. high, soft pubescent below, strongly glandular 

 pubescent above: the lowest leaves narrowly ovate; narrowed at 

 base, softly pubescent, denticulate, usually two pairs of linear 

 leaves on the stem: the heads on peduncles 5 to 10 cm. long, 

 with well developed rays: achenes pubescent. 



Similar in leaf and stem to Arnica Parryi A. Gray, the pu- 

 bescence notably glandular above, and the achenes seemingly 

 more pubescent, but differing mainly by the well developed rays 

 of the flowering heads. Collected on Alt. ^Cameron, Larimer 

 county, Colorado, altitude about 12000 feet, August 15, 1908, 

 no. 3814. 



New Windsor, Colorado.
