Help with fruit identification
Hi, I'm trying to identify a small fruit that grows on a medium-sized tree in my backyard in La Jolla, CA. The fruits are very hard and bright orange, turning black as they decay. They have a rib or seam running longitudinally and are slightly pear-shaped. They grow in bunches of 5 - 15. The flavor is citrus-like and extremely bitter. They are small, the size of a small grape.
