 survey emphasized relocating and mapping known 

 locations, although several new areas were 

 searched without result. The following areas in 

 Cascade County were searched in 1990, but Phlox 

 kelseyi var. missoulensis was not located at these 

 sites: portions of T14N R7E, Section 3, SW4 

 (Keegan Peak), and Section 15, NE4 (Belt Park 

 Butte) . 



E. HABITAT: Phlox kelseyi var. missoulensis occurs in 

 habitats that range from sparsely vegetated with dry 

 gravelly slopes, to heavily vegetated forb meadow 

 sites. Most sites are on windswept ridge crests on all 

 aspects.
