When is a May Apple no longer a May Apple?

Back in 2009, the since deceased Delaware Valley plantsman, Jim McClements, shared a may apple hybrid he’d created by crossing the US native Podophyllum peltatum with the Chinese native Podophyllum pleianthum. The offspring was named Podophyllum x inexpectum ‘Ruby Ruth’ (after his second wife). Our plant spent years in a much too dry a garden location until we relocated it to a bog setting alongside pitcher plants. Finally this year, we got our first flowers…a lovely bright red. Now the dilemma is that some Chinese researchers consider their may apple not to be a podophllum at all, but instead a sister genus, Dysosma. If we buy into that theory, then our plant becomes a bigeneric hybrid that will need a new nothogeneric name, either x Dysophyllum or x Podososma. After growing most of the growable species, I’m having a hard time supporting the idea of two separate genera, but we’ll see.
