Names and Taxonomy
Comments: Formerly considered a distinct species, E. lloydii. USFWS has agreed that it is a hybrid (Federal Register, June 24, 1999) and has delisted it, removing its endangered status. Kartesz (1999 floristic synthesis) treats as Echinocereus x roetteri; he notes (pers. comm. to Larry Morse, 25Nov99) that he follows Taylor's 1985 Echinocereus treatment for this taxon.
