Tree Identification - w/small fruits

I saw the following tree yesterday in the San Diego Zoo's collection. Does anyone have a clue as to what it is ? The fruits had very small "spikes" on them. The texture was almost like that of a lychee...

Sorry for the large picture, but I figure the more detail available, the better.

 

Arbutus Unedo ever green shrubs Mediterranean plant...

 

Yep, agree with Arbutus unedo (Strawberry Tree). The fruit is edible, but not very tasty.

 

Unum edo means "I eat one."

 

Mildy hallucinogenic too...if you eat enough of them (you didn't hear it from me).

 

Get that pink-and-purple striped elephant with a florescent pink lamp on its back to take its bright yellow and orange trunk from over your mouth and then we will be able to hear you.
