species, collections were made and identifications finalized at the Rocky Mountain Herbarium, 

 University of Wyoming (Laramie), or at Montana herbaria (Montana State University, and 

 University of Montana). Collections were also made of species for which the sighting 

 represented a significant range extension based on distribution information in Dorn (1984). All 

 specimens collected are deposited at Montana State University (MONT), with duplicates at the 

 University of Montana (MONTU) and the U.S. Forest Service Regional Missoula Resource 

 Center Herbarium (MRC). All vascular plants encountered at the appropriate mature 

 phenological stage were identified to species so as to consider prospective sensitive species not 

 included in the original target list and also to compile a preliminary flora for the District. 



Technical references most commonly used to key out plants were Dorn (1984, 1992), and 

 Hitchcock and Cronquist (1973). Nomenclature used in this report generally follows these 

 references. Taxonomic consultations were made for specimens of Astragalus spp. with Matt 

 Lavin, Montana State University, for SphenophoUs spp. with John Rumely, Montana State 

 University, and for Juncits spp. with Ralph Brooks, University of Kansas in select cases. 



Review and verification of specimens in the District CCC collection of important range plants is 

 in progress. Even though we are still waiting results from this review, we have included 

 information on two of the eleven species that are least likely to be misidentified, and which 

 represent species currently tracked by the Montana Natural Heritage Inventory. .
