We saw a lot of trees full of these last month in the Arkansas Ozarks while on a trailriding vacation. I asked a local and he said he didn't know what they really were but that they just called them Ozark Apples. Though they don't appear to be edible, I know if they grew down here in Southern Louisiana that the Cajuns would find some way to cook and eat them. There were so many on some trees that the branches would break off. WHAT IS IT?
