Geographic Range : Circumpolar , south in western North America to 



British Columbia and Alberta, disjunct in Beartooth and Wind 



River ranges of Montana and Wyoming. 



Habitat : Wet boggy soil of seeps and stream terraces above 



timberline. 



Occurrence : This species was known from the Beartooth Mountains 



of Wyoming, but was not collected in Montana until 1991. As of 



1993, there are four known sites for the plant in Montana, three 



in the Line Creek Plateau study area and one on the Hellroaring 



Plateau. Populations are very small and local, and the wetland 



habitat is fragile and easily disturbed. 



GENTIANA PROSTRATA Haenke (Moss gentian) [G5/S1] 



Geographic Range : Circumboreal , south in western North America 



to California and Colorado; South America. 



Habitat : Moist tundra and gravelly soil in the alpine zone. 



Occurrence : This inconspicuous plant is locally common in 



Glacier National Park, the Anaconda Mountains and the Beartooth 



Mountains. It has been observed in at least six places in seep 



areas and wet tundra on the Line Creek Plateau and probably 



occurs in many others. 



GENTIANELLA TENELLA Rottb. Borner (Slender gentian) [G4/S2] 

 Geographic Range : Circumboreal, south in western North America 

 to California, Arizona and New Mexico. 



Habitat : Moist tundra and wet organic soils above timberline. 

 Occurrence : This species occurs in the Beartooth, Absaroka, and 

 Gravelly ranges. It is locally common in the Beartooth 

 Mountains, but its habitat is fragile and easily disturbed. It 

 is a small, short-lived species that is easily overlooked. 



HAPLOPAPPDS CARTHAMOIDES (Hook.) Gray var. SDBSQDARROSDS (Greene) 



Dorn (Columbia goldenweed) [G5T2/S1] 

 Geographic Range : The range of the species as a whole is eastern 

 Oregon and Washington east to central Montana and western Wyoming 

 and south to Nevada and California. The variety is known only 

 from Park Co., Wyoming and adjacent Carbon Co., Montana. 

 Habitat : Sagebrush steppe in the lower montane zone. 

 Occurrence : This variety is not recognized by A. Cronguist, but 

 has a disjunct range and is quite morphologically distinct from 

 other Montana collections of this species. In Montana it is 

 currently known from only one large population in the foothills 

 on the east side of the Line Creek Plateau. 



JUNCOS TRIGLUMIS L. var.TRIGLUMIS (Three-flowered rush) [G5T5/SU] 



Geographic Range : Circumpolar, south in western North America to 



Wyoming and Colorado. 



Habitat : Wet, open, gravelly soil around seeps and streams and 



organic soil of boggy areas above timberline. 



Occurrence : In Montana, this species is found only in the 



Beartooth Mountains, where it is locally common. There are two
