Endemic to a small area straddling the Utah-Arizona state line, in northwestern Mohave County, AZ and closely adjacent Washington County, UT; closely associated with gypsum outcrops of the Harrisburg Member of the Kaibab Formation. Five occurrences are known, four in Arizona and one in Utah. The two largest occurrences in Arizona represent over 90% of the total population; both of these occurrences are threatened by active gypsum mining operations, which can completely destroy the plant's habitat. The Utah occurrence is threatened by increasing OHV use, illegal dumping, and impacts associated with target shooting. All but one occurrence are also within grazing allotments; cattle herbivory of flower stalks has been observed on numerous occasions, particularly in dry years.
