About Owenia acidula F.Muell.
Owenia acidula F.Muell., commonly known as emu apple, is a small or medium-sized tree native to Australia that grows in Australian outback woodlands. It can reach a maximum height of ten metres. This species has bright green, shiny pinnate leaves, with individual leaflets measuring between 2 and 5 centimetres long. When twigs are broken, they leak milky sap. The fruit of Owenia acidula is edible; it is purplish-red with pale speckles, measures 2 to 4 centimetres wide, and contains a large hard, stone-like seed. The fruit pulp is traditionally eaten as a bushfood by Aboriginal people, and it is reported to cause hallucinations. Fruits ripen after they have fallen from the tree, and have a sour flavour.
