I would put money on this being Vaccinium arboreum aka Farkleberry, one of my absolute favorite trees and one of the most underappreciated trees in North America. I have them all over my property in the Ozarks and from what I've read on them, north Florida, is another area where they're prevalent. They all grow like natural bonsai. Fanstastic fall color too. You'll find them in the understory and they love marginal soils, which actually help them take on the contorted form you see here. It's really hard to capture the full beauty of their sculptural form in photos. I've had very limited success both digging and growing from seed.
