The problem is that there's 2 species of I virginica. One of them
is I virginica var shrevei which is natural in a more northern area
than I virginica var virginica and is one the parents of the
original I versicolor. The native area for I vers and I vvs are
nearly the same, whereas the native area for I vvv includes just
the states north of the Gulf of Mexica. I versicolor is not native
to this area at all.
Interesting problem is whether the 2 virginicas will hybridize
which I would think is the case and whther I vvv can be back
crossed to I versicolor.
