﻿278 Nelson: New Plants from Wyoming 



long; corolla bright blue, turbinate-campanulate, 7 mm. long, 

 lobes equalling or surpassing the tube, lobes rounded, entire ; the 

 obliquely vertical lamellae broad and conspicuous, loosely united 

 over the filament ; anthers short-oblong ; filaments and style con- 

 spicuously exserted; style cleft below the middle; ovary oval, 

 pubescent, cells two-ovuled ; ovules oblong ; mature seeds not at 

 hand. 



Distinctively a desert plant, occupying the high, white, dry and 

 barren bluffs known as the Green River shales. It develops early 

 while the moisture from the spring snows make growth possible.

Phlon multiflora. 



Suffrutescent as to the caespitose, much branched, prostrate 

 base, the numerous herbaceous stems nearly erect, 6-10 cm. 

 high, the annual branches simple, one-flowered ; leaves broadly 

 linear, glabrous, apiculate, 1-2 cm. long, opposite or fascicled ; 

 peduncles finely pubescent, 1-3 cm. long ; calyx angled by the 

 prominent midrib of the lobes, membranous in the sinus only, 

 lobes linear-apiculate, equalling the tube ; tube of the corolla ex- 

 ceeding the calyx, lobes obovate, entire, 1 cm. long ; style equal- 



ling the calyx.

has been distributed under no. 182 from Laramie Hills, mostly as 

 P. longifolia Nutt., but from which, I now think, it is wholly dis-

 branches, less membranous calyx and numerous flowers easily 

 separate it. It is very abundant on the moister slopes and valleys 

 of the Laramie Hills at 8000 to 9000 ft., flowering from late 

 May till late June.

It seems to me that only lack of sufficient material can justify 

 leaving this as a variety. The points in which this differs from G. ag- 

 grcgata need to be emphasized. They are, as pointed out by Dr. 

 Gray, the considerably longer corolla-tube (about 3. 5 cm. as against
