Range
Montana endemic restricted to a very small area of the Bitterroot Mountains of Ravalli County, Montana with only a few known occurrences.[3]
Habitat

Etymology
Physaria humilis (originally known as Lesquerella humilis) was formerly described as a species in 1984 by Dr. Reed Rollins. It was first discovered on St. Joseph Peak in the Bitterroot Range in 1966, by Klaus H. Lackschewitz and Tor Fageraas. This first specimen, and other early collections, were variously labeled as Lesguerella alpina, Physaria didvmocarpa, or P. geveri, but Rollins ultimately determined that they represented a previously undescribed species. The type specimen was collected in 1983 by Reed C. and Kathryn W. Rollins, with Lackschewitz, Peter Lesica, and Aileen G. Roads, near the summit of St. Mary Peak, also in the Bitterroot Range. [3]
