The original name for this cactus was Trichocereus chiloensis. In 1950, Skottsberg pointed that the name was misspelled, and was changed to "chilensis" for "Chile"+"ensis". The rules of nomenclature now, give priority to the original name, misspelling included, except if the name was changed by the original author. Thus, Friedrich & Rowley retained chiloensis when they included the genus Trichocereus into the genus Echinopsis.
