Examination of specimens of Pediomelum in the Brigham Young University Stanley L. Welsh Herbarium (BRY), and others obtained on loan from the Northern Arizona University Deaver Herbarium (ASC), the Arizona State University Herbarium (ASU), and the University of Arizona Herbarium (ARIZ), allows for substantial reevaluations of the species in Arizona and for description of 2 previously undescribed species. Pediomelum verdiensis S.L. Welsh and M. Licher is described as a new species from substrate derived from the Tertiary Verde Formation, Verde Valley, north central Arizona. Pediomelum pauperitense S.L. Welsh, M. Licher, and N.D. Atwood is described as a new species from outcrops of Paleozoic limestone near Poverty Mountain, Coconino County, Arizona, north of the Grand Canyon. For the species of Pediomelum in Arizona, we include a summary revision, a key to the taxa, and a list of specimens examined for study.
