There were other name changes, but Oncidium is the one that most people prefer get reverted. There are some others like Rose Diana that are incorrect (should be Royal Princess), Cactace which (apparently) sounds silly, and so on.

There's also girls like Canola or Mei Plumblossom that are technically correct, but purists might still prefer Field Mustard/Rapeseed or Ume. I'd hope Nutaku doesn't revert those names, at least.
