CONTRIBUTIONS TO WESTERN BOTANY. 707 



corolla; scapes rather stout for the plant: capitate heads 

 of flowers subtended by obtuse, narrowly-oblong bracts, 

 2-3" long; flowers sessile or nearly so, 8 or more, in a 

 dense head; calyx narrowly-oblong, the lobes rounded 

 and obtuse; corolla purple, the tube barely surpassing 

 the calyx; lobes about i" long, throat yellow. This spe- 

 cies seems to be nearest to P. farinosa, and may be only 

 a form of it, but it seems distinct. 



Fraxinus anomala var. I-riphylla. 



No. 5082W. April 20, Pagumpa, Arizona, in the Grand 

 Wash, 4000° alt., among rocks, at the lower edge of the 

 juniper belt. 



Leaflets 3 and stalked. 



Gentiana tortuosa. 



No. 6008. September 7, 1894, Panguitch Lake, Utah, 

 8400° alt., in meadows. 



Prostrate from an annual root, tortuous stems rather 

 slender and entangled, 2-6' long; leaves linear-lanceolate 

 and acuminate, 2' long, little reduced above; plants Aur- 

 iferous from base to apex; peduncles slender, 1%' or 

 less long, tortuous, often deflexed in fruit; flowers sev- 

 eral to each node, white, 3-4" long, oblong-campanulate ; 

 lobes elliptical, acutish, nearly as long as the tube; fringe 

 reduced to scattered set^ on the base of the lobes; an- 

 thers nearly round, extrorse ; capsules short-stipitate, as 

 long as the calyx, oblong; seeds oval, |" long, smooth 

 and coat very close, yellowish; calyx tube almost none, 

 lobes linear, 2-3" long, rather unequal, nearly equaling- 

 the corolla or i|" shorter. 



This delicate little plant is near to G. AniareUa and 

 grows in similar situations in gravelly meadows.

No. 5684ak. July 25, Mt. Ellen Park, Henry Mts.,
