Location is South Florida and I have this tree in my backyard.

I have an olive tree in the front yard, but this one in my backyard I have no idea what it is. I was told by a neighbor once this may be an oak tree, but I am not so sure.

Here is a picture of the tree and it's trunk.

At this time of the year it's blooming with flowers.

The flowers are small, and they drop on the ground.

In fact, the dropped flowers formed a carpet on the ground and it's pretty amazing.

Any idea what kind of tree this is?
