What is this tree? I am worried about the brown edges of the leaves.
The tree is evergreen, and does not produce much litter at all, about 10 ft tall, 8 ft wide. It produces a lot of these fruits and have yet to see any ripe one yet (or is this a nut?). The fruit seems to be about 1/2" diameter and somewhat hard at present. (This is a new home and have yet to go through an entire season..) I don't see any remains of these fruits on the ground.
The leaves are turning brownish along the edge and about a 1/3 of the tree has these brown edges. I don't remember seeing the brown spots last year in this new house.
Tree: about 15 feet tall.. Location: San Francisco Bay area, California, USA Smell - has a familiar smell, but can't pinpoint it, like an unripe bittergourd melon. The closest I have gottten to identify based on pictures is 'osage orange'
