We encountered this fruit in a garden in Los Angeles. It was on a bush. We opened a small one and it had a soft but solid interior, with no obvious seeds or pits, but again, the one we opened was very small and possibly immature. The normal fruits were about the size of an egg. The point at the end of the fruit shown was a common feature among the full-sized fruits.
Any idea what it is?
The bush was about waist high (maybe a little higher), and probably about the size of a kitchen or dining room table? I have no sense of smell, but my companions didn't notice any strong scent either.
