hybrids and synonymy

[Richard Jensen]

I think Harvey has it right.  Michaux (the younger, I believe)
published Quercus heterophylla as a new species.  It was later determined
to be a hybrid between Quercus rubra and Quercus phellos.  Now it is
designated as Quercus x heterophylla Michaux, and it is not treated as a
synonym of either parent.
