That is not correct because a hybrid can even be crosses between two
subspecies, varieties, forms or even races of the same species. The point
being that a hybrid is a cross between two different plants regardless of
their taxonomic ranking.
I have something better than a dictionary, I've got the official rule book
for you to consult!
Check the International Code of Botanical Nomenclature, Appendix I, on the
naming of hybrids, particularly article H.10.
