D. GEOGRAPHIC DISTRIBUTION 



1. RANGE: Castilleja longispica is endemic to central 

 Idaho, northwest Wyoming, and southwest and south- 

 central Montana (Cronquist et al. 1984) . 

 Hitchcock et al. (1959) give a larger range 

 including the northern Great Basin, but this must 

 be based on the closely related C. pilosa. 



2. RECENTLY VERIFIED SITES 



a. PRYOR MOUNTAINS: Castilleja longispica 

 appears to be common on the south slopes of
