Of conservation concern. Potentilla albiflora grows on the Pinaleño (Graham) Mountains in Graham County, with a few outlying collections known from the Mogollon Rim in Greenlee County and the Santa Catalina Mountains of Pima County. Contrary to the specific epithet, petals of living plants are yellow, not white; like those of many Potentilla species, they tend to fade in pressed material.
