This tree was found on a nature path in the Fort Myers area in Florida. The leaves are compound, most are 5 compound but some are 7. They are similar to a buckeye tree.
This is a picture of the tree's bark.
My guess would be the Ceiba speciosa or Chrorisia speciosa. It's commonly called the silk floss tree and is a species found in Florida. The one you're looking at has bunches of conical "spikes" and appears to be quite aged or possibly diseased. Not easy to tell from a single photo.
You can read about them here, from the University of Florida. Notice the middle photo on page 2. Also, the wiki article. We had one at my college and it's quite messy when the pods open. And the leaves from a Southern California variety.
