Mentzelia pumila Torrey & Gray 



^ Dwarf Mentzelia, Small Blazing-star 



NATURAL HERITAGE PROGRAM S lATUS: G4/S2 



MONTANA STATUS: Sensitive 



GLOBAL DISTRIBUTION: Western North Dakota to south-central Montana, south to 

 Colorado, Utah and Nevada 



MONTANA DISTRIBUTION: Southern Carbon County 



PRYOR MOUNTAINS DESERT DISTRIBUTION: Mentzelia pumila is widespread 

 but uncommon below 1585 m (5200 ft) on the south and west sides of the Pryor 

 Mountains. Sparse populations occur in sandy soils (often Chugwater sandstone) in open 

 juniper woodlands and cushion plant communities dominated by Agropvron spicatum , 

 Ceratoides lanata and Phlox muscoides . 



MANAGEMENT RECOMMENDATIONS: Mentzelia pumila plants are sparsely 

 distributed within populations. We located only nine populations, most of which were on 

 Chugwater sandstone in the southeast pan of the study area. This species should be 

 given special status on BUM'S Miles City District.
