E. Photographs and line drawings: Figure 3 is a copy of the 



illustration which accompanied the publication of Shoshonea 

 pulvinata (Evert and Constance 1982). The color slides (p. 9) 

 are duplicates of those taken at the sites indicated. Additional 

 slides of Shoshonea and its habitat are housed at the office of 

 the Montana Natural Heritage Program, Helena, Montana. 



i*. Significance. 



A. Natural: Shoshonea is a monotypic genus. Its taxonomic position 

 indicates that it may contain a relatively large amount of 

 unique genetic material. The species is adapted to shallow 

 limestone soils in harsh windswept sites. It may be important in 

 stabilizing limestone talus slopes in some instances. Obligate 

 relationships with other species are unknown. 



B. Human; The Apiaceae is a taxonomically difficult family. The 

 discovery of this genus may help to elucidate generic 

 relationships within the Apiaceae. Shoshonea pulvinata may have 

 horticultural potential as a rock garden plant. Otherwise, the 

 species has no known agricultural, economic or other human uses 

 or significance. 



5. Geographical distribution. 



A. Geographical range: Shoshonea pulvinata is currently known in 

 Wyoming from the Absaroka Mountains, Park County, and the Owl 

 Creek Mountains, Fremont County, and in Montana from the Pryor 

 Mountains and Beartooth Mountains of Carbon County - 



B. Precise occurrences. 



1. Populations currently known to be extant. 



a. Montana: Populations are listed in Table 1, p. 10J 

 exact locations are provided in Maps 1-3, pp. 11-13. 



b. Wyoming: Populations are listed in Table 2, pp. 1^-16. 

 Since all of these populations have been discovered 

 within the last ten years, they are presumed to be 

 extant. 



S. Populations known or assumed extirpated: None. 



3. Historically known populations where current status is not 

 known: Although populations in Wyoming are all presumed to 

 be extant, survey work has not been completed in the last 

 several years. The current status of these populations in 

 terms of abundance and threats is not known. 



i*. Locations not yet investigated believed likely to support 

 additional natural populations. 



a. Wyoming: Much of the appropriate habitat in Wyoming
