Lomatium attenuatum G3S1 - Watch 3C 



Known from one occurrence on the Beaverhead National Forest in 

 the Tendoys near the crest of the range and from three sites 

 on BLM land in canyons of the northern foothills of the range. 

 The plants grow in soils derived from limestone in Douglas 

 fir, limber pine, and mountain mahogany communities. 

 Additional occurrences are likely on canyon and mountain 

 slopes in the range, in substrates derived from limestone and 

 possibly volcanic parent materials. The plants flower in 

 early spring and produce fruit in June. 



Lomatogonium rotatum G5S1 _ _ _ 



This species was collected for the first time in Montana by 

 Peter Lesica with Steve Cooper in 1994 from BLM land along a 

 tributary of Cabin Creek (upper Big Sheep Creek Basin). Here 

 it grows in saturated soil in a Potentilla fruticosa/Juncus 

 balticus community. Similar wet, alkaline habitats are found 

 on BLM and state lands in the basins in the vicinity, but are 

 not known from the Beaverhead National Forest in the Tendoys. 

 Flowering is in late summer. 



Penstemon lemhiensis G3S2 Sensitive Sensitive C2 



One occurrence is known from BLM land in the Tendoys in 

 Johnson Gulch, and another is reported from private land in 

 the valley of Medicine Lodge Creek. The species most commonly 

 occurs in sagebrush grasslands; apparently suitable habitat is 

 extensive on both BLM and Forest Service land at low to middle 

 elevations in the Tendoys. Flowering plants of this species 

 are very conspicuous but have been especially rare in recent 

 years and the species was not found by the recent MTNHP 

 surveys in the Tendoys. Plants flower in early June to late 

 July, depending on the site and the season. 



Phacelia incana G3S1 _ _ _ 



The Montana distribution of this species is limited to the 

 Tendoy Range where it is known from 5 sites on BLM land. This 

 annual species grows on limestone talus slopes often in 

 mountain mahogany communities. There is plentiful habitat for 

 the species and it is likely to occur in the canyons of the 

 Tendoys in the Beaverhead National Forest, but it was not 

 found by surveys in 1994, probably due to the hot, dry growing 

 season. The plant could not be found at its known locality at 

 upper Big Sheep Creek in 1994 either, although it was seen 

 here in 1993, a wet year. Plants flower in June and can be 

 identified in flower or fruit. 



Sphaeromeria argentea G?S1 _ _ _ 



One occurrence is known from state land in the drainage of 

 upper Big Sheep Creek where the habitat is an unusual low sage 

 (Artemisia arhuscula) and greasewood (Sarcobatus vermiculatus) 

 community in an alkaline basin setting. It has also been 

 collected to the east of Red Rock Creek in the vicinity of
