Not based on Cactus monacanthos Willd. Haworth 1819 refers to the Willd. taxon “Cactus monacanthos” with a question mark and changes the ending. The basonym “Cactus monoacanthos” can’t be typified as a specimen has not been located, we are not constrained to use the spelling “monoacanthos" and the Greek ending "-os"can be changed to a Latin ending ("-a") for the combination in Opuntia.
