and then we have these suffixes -opsis and -oides which both mean “like” as in “similar to.” I can’t think of it off the top of my head but I am pretty sure there was some plant that was cheating by just taking the genus name and adding the suffix to make the species epithet

Usually, the plant was originally named in a different genus. For instance, Linnaeus published Anemone thalictroides, which is a perfectly reasonable name for an Anemone that looks like a Thalictrum. Two hundred years later, Eames & Boivin concluded that it looks like a Thalictrum because it is a Thalictrum, so we get Thalictrum thalictroides.
