 (Houtcooper et al. 1985). 



3 . Occurrence in the study 

 area: It was collected at the 

 northwest end of the Slim 

 Buttes on three ridges north of 

 Government Hill. It had 

 previously been collected on 

 Slim Buttes in 1941 with no 

 futher location information. 



(From Great Plains Flora 

 Association 1977) 



There is potential habitat for it at the south end of the Slim 

 Buttes where Penstemon nitidus grows, as well as potential 

 habitat that is invaded by yellow sweet clover ( Melilotus 

 officinalis ) . It had also been collected from the "Short Pine 

 Hills" by Visher (1914) with no further location information. 

 Potential limestone outcrop habitat is found near the East 

 Short Pine Hills, but almost entirely outside (north) of 

 Forest Service boundaries, an area that was not searched. In 

 addition, this species is in all of the Montana units of the 

 District, where it is a characteristic species on the steepest 

 gravelly slopes. 



Habitat 



1. Associated vegetation: Douglas' dusty maiden occupies 

 sparsely-vegetated upland slopes with Andropogon scoparius or 

 Aqropyron spicatum being most common. Associated species 

 include low mat-forming plants like Erioqonum flavum,
