to count plants in the vegetative state for entire 

 populations, since the leaf morphology and 

 architecture of Thalictrum occidentale and A. 

 brevistvla are nearly indistinguishable in a 

 forest setting. 



Dry Pole (001) 



Population size: ca. 45 plants in 2 main 



subpopulations . 



Population condition: several plants show 



characteristics intermediate to A. brevistyla 



and A_^ f lavescens . 



Acreage covered by population: 1 



Last observation date: 1991 



Boulder River (002) 



Population size: 



Population condition: unknown. 



Acreage covered by population: unknown. 



Last observation date: 1967 



Sage Creek (003) 



Population size: ca . 2000 plants (1990), ca . 

 770 - 1000 in 1991. 



Population condition: site burned in fall of 

 1990, population size was difficult to 

 estimate in 1991 as a number of plants were 

 only in a vegetative state.
