7. GENUS: Castilleja is a genus of ca. 200 species, 

 most of which occur in western North America. 

 However, ca. 15 species occur in western South 

 America, and a few occur in eastern North America 

 and Asia (Cronquist et al. 1984) . Lines between 

 species are made ambiguous by widespread 

 interspecific hybridization (Hitchcock et al. 

 1959, Cronquist et al. 1984) . 



8. SPECIES: Castilleja longispica was first 

 collected by Aven Nelson in 1894 in Teton County, 

 Wyoming. It is closely related to C. pilosa 

 (Hitchcock et al 1959) and most recently has been 

 treated as a variety of C. pilosa (Cronquist et 

 al. 1984).
