Dwarf penstemon, endemic to east central Idaho, is distinguished by its compact growth habit (nearly cespitose), narrow hairy leaves, and sparse glandular hairs on the flowers and pedicels. This site lies at the south end of the Lost River Range, north of Arco, Butte County, Idaho. Eriogonum soliceps is growing to the left of mat of dwarf penstemon.

The sagebrush steppe on basalt caprock sometimes harbored a dense cover of Bromus tectorum and sometimes not. At this site with abundant Eriogonum, B. tectorum was relatively scarce. This site lies in the sagebrush steppe along the Columbia River near Echo Vista Viewpoint off I 90, Grant County, Washington (north of Vantage).

Western wallflower is abundant on the west side of New Army pass and consistently has a distinctive nearly stemless growth form in this area. This species is variably short to tall statured elsewhere and probably with a generally shorter stature at higher and more exposed settings.
