Sandbox Tree
Hura crepitans

You're unlikely to find one of these intact fruits of Hura crepitans.
This is because as they dry, they will break apart by "exploding" and sending component parts everywhere!

"Exploded" Pieces

Typically, what is found in the beach drift is only a semi-circular piece of the original seed pod.

The seed pod explodes, sending seeds and these semi-circular pieces of the pod in all directions.
