Idiospermum is a monotypic genus in the family Calycanthaceae. The sole included species is Idiospermum australiense − commonly known as idiotfruit, ribbonwood, or dinosaur tree − which is found only in two small areas of the tropical rainforests of northeastern Queensland, Australia. It is a relic of the ancient forests of Gondwana, surviving in very localised refugia for 120 million years, and displaying features that are almost identical to fossil records from that time. As such it provides an important insight into the very early evolution of flowering plants.
Atractocarpus fitzalanii, commonly known as the brown gardenia or yellow mangosteen, is a species of plant in the coffee and madder family Rubiaceae.

Neostrearia is a monotypic genus - i.e. a genus containing only one species - of plants in the witch-hazel family Hamamelidaceae. It is the second described of three monotypic Australian genera in this family, the others being Ostrearia and Noahdendron. It is most closely related to these genera, as well as Trichocladus from southern Africa and Dicoryphe from Madagascar, and together these five genera form a distinct clade within Hamamelidaceae.
