And that's just a simple one! Cattleyas, laelias, and sophronitis, as another example, may-, or may not be cattleyas now, depending upon who you talk to, and stuff like anacheilium have, at one point or another - sometimes reverting - been encyclia, epidendrum, and prosthechea, sometimes a single species being renamed, in addition to the change in genus.
