Yes, The dorsal is very original for a roth and I keep this plant only for that.
For the name of parents, there are many doubts.
According to a friend, It would be rather a seedling from a wild colony. This kind of dorsal would be more characteristic.
But we will never know the truth...
Slipperking, is it possible for you to add photos of GV and Butterfly please? Just to see what is probably impossible, even if genetic is sometimes mysterious...
I think there's also "Dou Fong" in this book.
I have GV X Dou Fong in bloom (photos tomorrow) from Sam and it's maybe the same thing. The member Sanderianum told us it was not possible to have roths with Dou fong like parents.
I don't know what are the parents for mine but it's awesome.
