TECHNICAL DESCRIPTION: The flowers are borne in one 

 or more very dense, capitate or spicate-capitate 

 clusters. The filaments are 2 to 4 times as long as 

 the anthers. The stems are basally branched and 

 woody. The leaves are green and glabrous or nearly 

 so, generally many of them crowded on short, sterile 

 shoots near the base. 



LOCAL FIELD CHARACTERS: Ipomopsis conqesta ssp 

 crebifolia is distinguished by the narrow, 

 glabrous, "evergreen-like" leaves and the clustered 

 white flowers. 



D. GEOGRAPHICAL DISTRIBUTION 



1. RANGE: Ipomopsis conqesta ssp crebifolia is a 

 regional endemic found in southwestern Montana to 

 northern and western Wyoming. 



2. CURRENT SITES: Ipomopsis conqesta ssp crebifolia was 

 found in abundance on the southwestern portion of 

 Centennial Valley. The plant was thriving in 

 disturbance area, e.g. road cuts, soil slumps, or 

 eroded hillsides from Monida, MT to Bear Creek 

 (approximately 15 miles east of Monida) . In Montana, 

 it is known only from the Centennial Valley. 



E. HABITAT 



1. ASSOCIATED VEGETATION: Ipomopsis conqesta ssp 

 crebifolia occurs on dry slopes at mid to high 

 elevations. The sites occurred in open sagebrush 

 ( Artemisia tridentata, A. nova ) with the following 

 grasses and forbs: 



Chrysothamnus nauseosus (rubber rabbitbrush) 

 Chrysothamnus viscidif lorus (green rabbitbrush) 

 Penstemon erianthus (crested tongue penstemon) 

 Senecio canus (wooly groundsel) 

 Aqropyron spicatum (bluebunch wheatgrass) 

 Aqropyron smithii (bluestem wheatgrass) 

 Lupinus sericeus (silky lupine) 



2. TOPOGRAPHY AND SOILS: Ipomopsis conqesta ssp 



crebifolia was found at elevations ranging from 6800- 

 7200 feet along open sagebrush grasslands in disturbed 

 areas in clayey soils.
