2. Populations known or assumed extirpated 

 (Montana): Prior to 1989, two historical 

 records were known in Ravalli County: 



a. 1950: T.G. & V.C. McCall (352) . MONTU 

 (49394), "(b)etween Conner and Sula, on 

 rocky hillside above river." 



b. 1952: J.C. Wright s.n. . MONT, "10 miles 

 east of Darby, Sapphire Mountains 

 foothills, sandy granitic soil, ponderosa 

 pine zone." 



These areas were emphasized during field 

 surveys in 1989. Although the original label 

 data from both collections are general in 

 nature, it is believed that both collection 

 sites, or populations very near to them, were 

 rediscovered. The element occurrence print- 

 outs for these sites (007 and 004, 

 respectively) are provided on pp. 59 and 56. 



3. Historically known populations where current 

 status is not known: In Montana, one 

 population in Beaverhead County (Medicine Lodge 

 Creek, 022; see p. 74) has been reported by J. 

 Christensen (Beaverhead National Forest) . 

 Surveys adjacent to this location did not 

 reveal any populations (L. Schassberger, MTNHP, 

 pers. comm.); access to the site itself was not 

 possible because permission to cross private 

 land could not be obtained. 



Another population in Beaverhead County, 

 Montana (021; see p. 73) is based on the 

 following specimen: 



a. 1947: Frank H. Rose (3502) . MONTU 

 (092520), "(w)est of Big Hole 

 Battlefield." 



Although P. lemhiensis is recently documented 

 from the Big Hole National Battlefield proper, 

 surveys have not yet been conducted in areas 

 west of the battlefield. It is likely, 

 however, that the species is extant in this 

 area. 



Four records in Idaho are based on historical 

 collections, taken in 1920, 1937, 1938, and 

 1946; details on these collections are 

 available from the Idaho Natural Heritage 

 Program.
