No it isn't just you Tony, it happens with me as well.
Interestingly I tried navigating to it through the Recorder 3.3 hierarchy instead of searching. As far as I am aware Petunia should be in the Solanaceae, but the genus is not there in the Recorder 3.3 list.
So how is it that the search tool manages to find it in the list?
This may not be as trivial an error as it at first appears, how do we know how many taxa this occurs with?
I'm guessing this taxon has got orphaned in some way, but I'm afraid I find the structure of the taxon dictionary too arcane to be bothered to do the analysis & work out what the problem is for a plant I have never recorded.
