Future Work 



To gain a complete understanding of C^ lonqistylum , the 

 following additional work is needed: 



1) A restriction site analysis of chloroplast DNA should be 

 performed on C^^ lonqistylum and all closely related species. The 

 phylogeny derived from these data will be the cornerstone of our 

 understanding of the genetic significance of the C_^ lonqistylum 

 lineage and the evolutionary events that occurred in Montana. 



2) Gain a better understanding hybridization and 

 introgression in Montana by obtaining essential information on 

 the variability of C_^ hookerianum and C_^ scariosum throughout 

 their geographic range. 



3) Study the morphology of genetically pure C^ lonqistylum , 

 C. hookerianum . and C^ scariosum so that botanists and managers 

 can more easily interpret plants encountered in the field.
