Within the Boise Front boundaries, Douglas’s draba (Cusickiella douglasii, previously in Draba) is currently known only as a rare plant scattered in open flats along the Oregon Trail west of Bonneville Point.  The small dense perennials are covered with white flowers in late winter/early spring, blooming at the same time as sagebrush buttercups and orogenia.  How much longer even this population will persist remains to be seen; most of the existing plants are struggling to hold their own against invasive bulbous bluegrass (Poa bulbosa), which flourishes in the same microhabitat.
