I agree. There is actually very little of regelia flower characteristics to
be seen in most modern OGB arilbreds (*especially * Shockey's!). Not only
has selective breeding strongly favored the onco characteristics, but there
was probably not a lot of regelia ancestry in the first place. Most
arilbreds descend rather directly from C.G. White's first fertile
amphidiploids, which were mostly of unknown parentage. They are classified
OGB rather than OB in recognition of the fact that we really don't know
which arils might be present somewhere in their ancestry. There is probably
some regelia in them, but nowhere near half--more likely a few bits that
made their way into the oncocyclus genome through crossover.
