The vascular flora of the Orange Cliffs area, defined here as part of the Colorado Plateau floristic province, harbors approximately 209 species in 123 genera and 49 families. A species checklist is provided with a discussion of physical and floristic aspects of the region. The flora is compared statistically to the San Rafael Swell flora, which is also a subset of the Colorado Plateau. We define six vegetation types and three edaphic communities; these are described and mapped. Of eleven endemic plant species in the Orange Cliffs, three are local and rare. Sites for Astragalus nidularius, A. moencoppensis, and Xylorhiza glabriuscula var. linearifolia are discussed and mapped.
