Natural interspecific hybridization within plants is relatively common and plays an important evolutionary role. Hybridization between rare and common taxa is of concern due to questions of protection status related to hybrids. However, field based identification of hybrid plants can be challenging. Sclerocactus glaucus (Cactaceae), the Colorado hookless cactus, is protected under the Endangered Species Act and has a small range around Grand Junction, Colorado, where populations are threatened… Expand
