Someone submitted data proposals for two of those Buddlejas you added, Dave, and I noticed the new entry format and applauded it because it removes so much ambiguity.
Choosing the spot for the trademarked series name always seemed rather arbitrary before.
While I was approving those proposals, however, I also made a change in the names of the two plants because "hybrid" isn't an accepted species name for most genera. According to The Plant List, there can be a Petunia x hybrida, for example, but no Calibrachoa x hybrida or Buddleja hybrid. I subsequently saw that you had created those entries. What's your thinking on this? Should we be treating "hybrid" as a valid species name?
