Thanks for your input! If I can find again the passage I read a while back about the 3rd petal, I'll put a link here. If my old bifocaled old eyes are seeing something that nobody else does, that's good to know and would be good cause to disregard.
The parent plant entry is a perfect solution only available here on NGA for great but questionable pics until/unless an agreement can be reached about what (other) species they are. In this case, those on which everyone agrees are definitely Commelina but not C. communis, species unknown. If others agree that some of the pics can't be confirmed as C. communis, I would support moving to parent if opinions are being considered.
