Idiospermum

Idiospermum australiense, the sole species in the genus Idiospermum, is one of the most primitive flowering plants known, having lived in the Daintree Rainforest of Queensland, Australia for up to 120 million years. It is only found in very few locations of North Eastern Queensland (e.g. Daintree National Park) in the very wet lowland parts of the forest, where it grows in groups of 10-100 trees together (rather than scattered individuals). Common names include Ribbonwood and Idiot Fruit.
