Abstract: This list represents my in-progress flora of the Salero Ranch for the Plant Atlas Project of Arizona (PAPAZ). I update it as I find new taxa or correct errors. The list includes five taxa that are native to Arizona but not considered native to the flora area: Encelia farinosa, Senna covesii, Sphaeralcea emoryi subsp. variabilis, Cissus trifoliata, Larrea tridentata. They were introduced in various ways, including accidentally and through revegetation following a mine clean-up.
