There is a plant sitting on a shelf in approximately one out of every three hobbyist collections, labeled Monstera adansonii, that is not Monstera adansonii. It arrived that way from a big-box store, or from a seller on a Facebook group who got it from another seller who got it mislabeled at a wholesale nursery sometime around 2018. It has oval fenestrations, a vining habit, smallish leaves, and absolutely no documentation. Everyone who owns it is confident about the name. Almost none of them should be.
This is not a story about gatekeeping. It is a story about how a single species epithet became a catch-all for at least four morphologically distinct plants, how a geographic modifier — 'Peru form' — got attached to something that may never have been collected in Peru, and why untangling the mess matters if you are trying to grow these plants well, source them honestly, or understand what you actually have climbing your moss pole.
