Vanilla Orchid?

[DLFL]

This from Dr. Prem Subrahmanyam of the University of Florida,"unfortunately, that flower is not an orchid. It is commonly known
as the pawpaw (Asimina sp. - which species it is would be hard to ID from
the photo). These are common in dry pine and mixed pine/oak forests.
One bonus, however -- the plant produces small fruits that ripen in
autumn and are edible, provided bugs and other critters don't get to
the fruits first."
