Scientific nomenclature follows Hitchcock and Cronquist (1973) and Hitchcock 

 et al. (1955-1969). Conion nanes were mostly taken from these sources. 



*Taxa listed by Thompson and Kuijt (1976b) for the Sweet Grass Hills, but which 

 were not observed during 1989 WESTECH surveys: although some of these species are 

 located on lands outside the PACEC, many are expected to occur within the PACEC.
