Three species are known growing naturally in southern Africa, including two species endemic to South Africa and one species in South Africa, Eswatini and Mozambique.
Elattostachys is a genus of about 21 species of trees known to science, constituting part of the plant family Sapindaceae.
Lepiderema is a genus of nine species of trees from the family Sapindaceae. As of November 2013 botanists know of seven species growing naturally in Australia and two species in New Guinea. Published botanical science provides a limited knowledge of the full range of diversity in Australia and especially in New Guinea. In New Guinea the two known species have descriptions based each on only a single type specimen collection. Therefore, collection of more specimens and more species is most likely in New Guinea. In Australia they grow in rainforests of the northern half of the east coast side of the Great Dividing Range, from northeastern New South Wales through to northeastern Queensland.
Mischocarpus is a genus of about nineteen species of trees known to science, constituting part of the plant family Sapindaceae. They grow naturally from Australia and New Guinea, though Malesia as far north as the Philippines, through SE. Asia, Indo-China and S. China, to India at their farthest west. The eleven Australian species known to science grow naturally in the rainforests of the eastern coastal zone of New South Wales and Queensland, from Newcastle northwards through to north-eastern Queensland and Cape York Peninsula.
Karrabina benthamiana is a species of rainforest trees, growing naturally in north–eastern New South Wales and south–eastern Queensland, Australia. They have common names including red carabeen, leather jacket, brush mahogany, red bean, pink marara and brush mararie. This species used to be placed in the genus Geissois as Geissois benthamiana.
Jagera pseudorhus, commonly named foambark, is a species of rainforest trees, in the northern half of eastern Australia and in New Guinea, constituting part of the flowering plant family Sapindaceae. Named for the saponin foam that forms on the bark after heavy rain.
Trochocarpa is a genus of shrubs or small trees, of the plant family Ericaceae. They occur naturally through coastal and montane eastern Australian rainforests and mountain shrublands and in New Guinea, Borneo and Sulawesi (Malesia).
Karrabina biagiana is a species of large rainforest trees commonly known as northern brush mahogany, northern brush mararie or red carabeen, in the plant family Cunoniaceae. This species used to be placed in the genus Geissois as Geissois biagiana.

Carnarvonia araliifolia, commonly known as the red oak, red silky oak, Caledonian oak or elephant's foot, is the sole species in the monotypic genus Carnarvonia, a member of the Proteaceae plant family. It is endemic to the rainforests of northeastern Queensland.
Eucryphia wilkiei is a species of rainforest shrubs endemic to restricted areas of cloud forests on mountain tops in the Wet Tropics region of northeastern Queensland, Australia. As of November 2013, botanists classify Eucryphia in the family Cunoniaceae.
Cnesmocarpon is a genus of 4 species of rainforest trees known to science, constituting part of the plant family Sapindaceae.
Alectryon connatus, sometimes named hairy alectryon, is a species of small tree in the plant family Sapindaceae.
Hollandaea sayeriana, sometimes named Sayer's silky oak, is a small species of Australian rainforest trees in the plant family Proteaceae.
Ackama paniculosa, synonym Caldcluvia paniculosa, known as the soft corkwood, is a rainforest tree of eastern Australia. It occurs from Ourimbah, Central Coast at 33° S to Eungella National Park in tropical Queensland. Other common names include corkwood, rose-leaf marara, brown alder and sugarbark.
