(Willd.) Haw.
Willd.
Haw.
1819
81
monacantha
based on Cactus monacanthos Willd. Haworth 1819 clearly refers to the Willd. taxon “Cactus monacanthos” but changes the ending. The Greek ending "-os"cannot changed to a Latin ending ("-a"). The name Cactus monacanthos Willd. (1814) was cited by Haworth with a question mark after the first pargraph. It is not clear what exactly the "?" refers to, but there is no "?" after the second paragraph referring to the Willdenow description. We accept Cactus monacanthos Willd. as the basionym of Opuntia monacanthos.
