redstem monkeyflower, Erythranthe rubella, California, White Mountains, Pellisier Creek, Hammil Valley - Owens Valley drainage, elevation 1774 m (5820 ft).

This is a common species of open rocky habitats in the deserts and mountains of the southwestern United States and adjacent northwestern Mexico. It really shows up in wet years like this, and sometimes not at all in dry years. In between, it is often restricted to more sheltered rock crevices where moisture can concentrate.

This is one of the monkeyflower species with both pink and yellow flower color forms. Sometimes only one form is present in a population, but the other form is usually nearby, as another post will show soon.
