Halimolobos virqata G2G3S2 - Sensitive - 



Four occurrences are now known from the Tendoy Mountains 

 vicinity on BLM and state land. One population is on dry 

 slopes in a mountain mahogany community in Pileup Canyon and 

 the other is on a seasonally moist bench in a sagebrush 

 community in Limekiln Canyon. Two additional populations were 

 found in 1994 by Peter Lesica in the northern foothills of the 

 range, and in the basin of upper Big Sheep Creek. It should 

 be looked for at lower elevations on the Beaverhead National 

 Forest in the Tendoys. The species flowers early and produces 

 fruit in June and July. It is most easily identified in 

 fruit. 



Haplopappus macronema ssp. linearis G4T7S2 - Watch 

 One occurrence is known from state land in the drainage of 

 upper Big Sheep Creek. The habitat is an Artemisia 

 tripartita/Festuca idahoensis community in a basin setting. 

 Similar habitats are most common on BLM land but the species 

 should be sought at the lower elevations of the Beaverhead 

 National Forest in the Tendoys, The flowering period is late 

 July to September. 



Hutchinsia procumbens G5S1 _ _ _ 



This annual is known from one occurrence on BLM land above 

 upper Big Sheep Creek, where it grows on the same slope with 

 Agastache cusickii and Phacelia incana. It is also known from 

 a historical collection from Armstead, now submerged by Clark 

 Canyon Reservoir. The plant usually grows along the edges of 

 alkaline or saline waters but at upper Big Sheep Creek it was 

 found on limestone talus under sagebrush. It should be looked 

 for in its primary habitat on BLM land along the shore of 

 Clark Canyon Reservoir and other alkaline wetlands, but may 

 also occur on limestone talus slopes in the canyons of the 

 Tendoys. Plants flower in early summer. 



Kochia americana G5SH - - ~ 



This Great Basin species is known from Montana only by two 

 historical collections from Beaverhead County. The reported 

 occurrence on the Beaverhead National Forest near Medicine 

 Lodge Peak has been investigated but not located. The 

 location data given on the specimen label (also mapped in 

 Figure 2) is probably wrong ; the cited legal description and 

 elevation are in conflict and vegetation in the area is not 

 appropriate for the species (Vanderhorst 1995c). This species 

 usually grows in barren, alkaline habitats and is most likely 

 to occur on BLM, state, or private land in the basins 

 surrounding the Tendoy Mountains (Muddy Creek, Big Sheep, Red 

 Rock) . The plant flowers in middle to late summer, and 

 flowers may be required to distinguish this from species of 

 Sueada.
