Does anyone know what type of tree this is? Someone told me it's a black olive tree — not the fruiting one — but when I google that, I can't seem to find any zoomed-in shots of the leaves to be able to ID properly...
Compare to Pseudoziziphus celata (Florida jujube). IF that is what it is it is very rare. I've never personally seen one but initially thought it was the California species P. Parryi.
