Hagener (1972) and Hagener and Hagener (1977) list common plants of 

 north-central I-'ontana. 



^pendix A lists plant species encountered during the 1989 rare plant 

 inventory. Appendix A also lists additional species recorded for the 

 Sweet Grass Hills area by Thcnpson and Kuijt (1976b), but v.-hich v/ere 

 not observed in the rare plant inventory conducted by VJESTECH. 



A total of 339 species v;ere recorded, of v±iich 71 were gramiroids, 228 

 \'?er^ forbs, 27 v;erB Icf^i shrubs and subshrubs and 13 v.ere trees and tall 

 shrubs. Seme of the taxa listed by Thcrtpson and Kuijt (1976b) may not 

 occur vd-thin the PACEC boundaries surveyed by VESTECH; ha.'^ver they are 

 at least proxirral and are included in Appendix A since many of these 

 species are expected to occur in the PACEC. 



Although very few rare plant species have been listed for the Sv^eet 

 Grass Hills and vicinity (Lesica et al. 1984), a number of taxa are of 

 phytogeographical interest due to island biogeography considerations. 

 Sore species within the PACEC which may represent range extensions of 

 subalpine/alpine taxa are included in Table 1. Thcrrpson and Kuijt 

 (1976a) listed cordilleran species of phytogeographic interest in the 

 a-reet Grass Hills.
