I was told that this was a Cerbera manghas (common name: Sea Mango; Family: Apocynaceae) when it was planted. But Cerbera manghas it is not.The true Sea Mango's flowers have a pink to red eye or throat. But this one has a yellow center, much like those of Cerbera odollam (common name: Pong Pong, Suicide Tree).
Anyway, the remnant white calyces (collective term for the sepals) looked like stars. A link on the C. manghas is attached below:
