This may very well be something else, but I've been calling it "Miami" since I found it. The original plant is in the Cutler Ridge area of South Miami. It was growing between a Bogoriensis and a Mortii that were both much larger than it. Single trunk and I'm guessing it may have been a seedling cross between the two. Note the red mid vein and red on the underside of the leaf. In the shade, this one goes from yellow to red. If there's no positive ID to this one, I'll add it to the on-line reference under the name "Miami".
