depends on what peoples definition of hybrid is as opposed to crossbreeds
pawpaw cross breeds within Asimina triloba x asimina triloba
this is just what I call plants cross breed when same species
I am not the best with all terminology
intraspecific hybridization like a horse is Equus with a Donkey also Equus (but different species (makes sterile offspring or mule )
I know some people call crossing 2 species of the same pawpaw cultivar
(asimina triloba x asimina triloba a hybrid, but me personally I prefer crossbreed)
on the other hand a Pawpaw Asimina triloba x Asimina parviflora
(I would call intraspecific hybridization or just Hybrid )
Like the Horse x donkey is listed -- (but a horse, and horse I would not say hybrid some people do though with plants)
