Opuntia gilvescens is a widespread prickly pear cactus; the authors have found it in OK (Arbuckle Mountains and west), in western TX, in many parts of NM as well as in AZ, southern portions of NV, UT, and CO, and in the mountains of the eastern CA Mojave Desert. Similar-appearing prickly pears have been found in the mountains east of Palm Springs, CA.
