Distinguishing features: Distinguished by simple leaves with silver, green or brown scaly Green fruit & leaves with a hooked tip undersurface; curved leaf tip; absence of small depressions between the main and secondary veins on the back of the leaf (domatia); fruit to 1 cm long, purple-black and succulent when ripe.

Confused With: There is confusion as to where subspecies cuspidata and subspecies europaea are naturalised in Australia.

Notes: A locally common weed of roadsides, neglected land and stream banks. African Olive produces fruit that are usually smaller and less fleshy than those of cultivated for edible and olive oil.
