Floristic Diversity

The species listed to the right were reported from Red Butte Canyon by Cottam and Evans (1945) and by Bates (1963). Not only is the presence of these plants unverified by herbarium specimens (see Albee et al. 1988, which is based on speciments in the herbaria of Brigham Young University, Utah State University, and the University of Utah), but at least six of them would not ordinarily occur within the elevational limits of the canyon.
