TREE AND SHRUBSLeaf it to me

what type of tree has leaves and pods like a mimosa and small white flowers that look like orchids?

I live in south florida and I have a tree that I am trying to care for but I can’t properly identify it. At first I thought it was some kind of mimosa tree, but the blooms are totally different. They aren’t “fuzzy”. They look like tiny white orchids. So far, I know it is NOT a Japanese pagoda tree.it does have fern like leaves and produces pods. Does anyone have any idea what I am trying to describe?
