A Lychee by Any Other Name...

We have one lychee tree. I only discovered it was a lychee after learning a bit from a dear neighbor. It hadn't produced fruit before, probably because of my inappropriate pruning.
But this year, I was ready. I waited and yes, it fruited. One fruit in the whole tree. (Pictured here.)
But this is my question South Florida friends: What other names are there for these fruits?  Have you heard of them called Soapberries?
