We can't add entries for species that don't exist. The problem, Lynn, is that they won't necessarily be classified as Anemone campanella and Anemone turczaninovi. They're much more likely to be added to an existing Anemone species. It all depends on DNA tests, I suppose.
The problem with The Plant List is that it's sometimes so hopelessly out of date that the necessary changes in classification are no longer listed in the more current databases.
