Pittosporum species with white flowers and yellow fruits, narrowed at base. SFO Zoo
What a coincidence my friend. I photographed this when I posted "porcupine" plant like 2 days ago. I think it is a Pittosporum tobira.
you know I have been wrong many times before!
More likely to be Pittosporum undulatum.

This is what I thought was P. tobira uploaded by me
I think the key difference like you stated is the narrow base of fruit. P. tobira' fruits are more rounded. I am not sure.
