pastures suggests that C. longispica is 

 avoided by cattle. 



Late in the season (August) the leaves and 

 bracts of some C. longispica plants appeared 

 ragged. These plants may have suffered 

 insect herbivory. The effects of this 

 herbivory on the plants is not known. 



HYBRIDIZATION: There are few barriers to 

 hybridization in the genus Castilleja other than 

 different chromosome numbers (Cronquist et al. 

 1984) . At many of the sites in the Pryor 

 Mountains C. longispica occurs in close proximity 

 to either or both C. pallescens or C. cusickii. 

 Castilleja longispica has an equally four-lobed 

 calyx, while the latter two species have deeper 

 calyx divisions on top and bottom than laterally. 

 Intermediates in this character were not observed. 



H. LAND OWNERSHIP 



U.S. FOREST SERVICE: All of the known occurrences 

 of Castilleja longispica on the east front of the
