Owenia acidula

Owenia acidula, commonly known as emu apple, is small or medium-sized tree of outback woodlands native to Australia.

[1] The pinnate leaves are bright green and shiny, with leaflets 2–5 cm long.

The edible fruit is purplish-red with paler speckles, 2–4 cm wide with a large stone-like seed.

The fruit pulp is an Aboriginal bushfood and apparently causes hallucinations.

The fruits ripen after falling off the tree, and have a sour flavour.
