('■>:\'2 Rvdberg : Rocky Mountain flora 



This belongs to the Amarella group of Gentiana and is perhaps 

 most nearly related to G. plebeja, which, however, has shorter ovate 

 or ovate-lanceolate, acute or obtuse stem-leaves, lower stem and 

 shorter and more nearly equal calyx-lobes. G. dementis grows in 

 the mountains from South Dakota and Montana to Colorado and 

 Arizona. As the type I regard the following: 



Colorado: Minnehaha, 1901, Clements 253. 



Frasera speciosa stenosepala van nov. 



Usually with very numerous flowers ; sepals narrowly linear, 

 ■some of them usually equaling or exceeding the petals ; petals 

 large, about 15 mm. long or more; floral leaves very long and 

 narrow. 



In the mountains and foothills of Colorado and Wyoming. As 

 the type may be regarded : 



Colorado : Foothills, Larimer County, 1895, Cowen. 



Frasera speciosa angustifolia var. nov. 



Low, 3-4 dm. high ; basal leaves veiy short; stem-leaves nar- 

 rowly linear-lanceolate ; floral leaves, except the lower, shorter 

 than the branches of the inflorescence ; petals rather small, about 

 1 2 mm. long. 



On dry hillsides from Montana to Colorado. As the type may 

 be regarded : 



Montana: Lima, 1895, Shear jj6g. 



Gilia scariosa sp. nov. 



Perennial with a tap-root ; stems one to several, simple, strict, 

 3-6 dm. high, glandular-puberulent throughout ; leaves numerous, 

 alternate, pinnatifid with linear-filiform spinulose-tipped divisions, 

 more or less white-villous when young, glandular-puberulent ; 

 inflorescence a narrow, strict, interrupted thyrsus ; branches very 

 short, few-flowered ; calyx-tube about 6 mm. long, puberulent, 

 scarious except the green angles ; teeth short, broadly rounded- 

 ovate, abruptly contracted into a subulate acumination ; corolla 

 pink, 3-4 cm. long ; tube narrow, very gradually broadening 

 upwards ; lobes ovate-lanceolate, acute, about 8 mm. long ; stamens 

 very unequally inserted ; capsule obovoid, about 1 cm. long. 



This is closely related to G. aggnga/a, but differs in the scari- 

 ous calyx with short, abruptly cuspidate-acuminate lobes. The 

 lobes of the corolla are also acute rather than acuminate. The
