As far as I know there are no real accepted rules within the hobby for what to call some crosses. I think most of us would call that cross (speck X florida) a non-natural intergrade.
Most people in the hobby accept the definition of a hybrid as a cross between two different species or genera, but in the world of biology a cross between two subspecies of the same species is called an intra-specific hybrid.
A hybrid is really a cross between two different kinds of anything. Remember Mendel's experiment crossing short and tall pea plants? Those were considered hybrids even though they were the same plant (different phenotype/genotype). By that definition crossing two different patterns or morphs or localities of the same sub-species would be a hybrid.
As far as captive bred snakes go, I'll think I'll stick to the accepted protocol of calling a cross at the species level or higher a hybrid.
