Sankowskya is a genus of plants. The sole known species, Sankowskya stipularis, is a tree endemic to one locality in the Wet Tropics rainforests of northeastern Queensland, Australia. The species constitutes part of the plant family Picrodendraceae. Few botanical collections have ever been made of the trees, from a very restricted area of the Wet Tropics rainforests, hence the species has obtained the conservation status of "endangered" in the legislative regulation of the Queensland Government's Nature Conservation Act 1992. Notably, trees grow naturally in the Thylogale Nature Refuge.
Galbulimima is a genus of flowering plants and the sole genus of the family Himantandraceae. Members of the family are found in the tropical zones of eastern Malaysia, the Moluccas, the Celebes, New Guinea, northern Australia and the Solomon Islands.
Pilidiostigma is a genus of shrubs and small trees in the myrtle family Myrtaceae. All species occur in Australia and one, P. papuanum, also occurs in Papua New Guinea. They are not generally known to horticulture. The species P. sessile is rare.
Diploglottis is a genus of 10 species of trees known to science, constituting part of the plant family Sapindaceae. They grow naturally in rainforests and margins of adjoining humid forests in eastern Australia and New Guinea. Some species are known as native tamarind or small-leaved tamarind; they have no direct relationship with the true tamarind.
Atalaya is a genus of eighteen species of trees and shrubs of the plant family Sapindaceae. As of 2013 fourteen species grow naturally in Australia and in neighbouring New Guinea only one endemic species is known to science. 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.
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.
Xanthostemon is a genus of trees and shrubs, constituting part of the myrtle plant family Myrtaceae. This genus was first described in 1857 by German–Australian botanist Ferdinand von Mueller. According to different official sources between 46 and 51 species are known to science. They grow naturally in New Caledonia, Australia, the Solomon Islands and Malesia, including the Philippines, New Guinea and Indonesia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Bernard Hyland, known as Bernie Hyland, has a long career as an Australian botanist.
Xanthostemon verticillatus is a species of trees from the plant family Myrtaceae endemic to the Wet Tropics rainforests of northeastern Queensland.
Stockwellia is a monotypic genus in the flowering plant family Myrtaceae. The sole species in the genus, Stockwellia quadrifida, is endemic to Queensland.
Hollandaea is a small genus of plants in the family Proteaceae containing four species of Australian rainforest trees. All four species are endemic to restricted areas of the Wet Tropics of northeast Queensland.
Carnarvonia is a flowering plant genus of a single species, commonly named red oak or red silky oak and constituting part of the plant family Proteaceae. The single species named Carnarvonia araliifolia grows to large trees of 30 m (100 ft) or more. They grow naturally only (endemic) to the Wet Tropics rainforests region of north-eastern Queensland, Australia. The species has two described varieties, C. araliifolia var. araliifolia and C. araliifolia var. montana, and the common names are used for both.
Helicia lewisensis is a species of rainforest trees, of northeastern Queensland, Australia, from the flowering plant family Proteaceae. It is endemic to the northern upland rainforests of the Wet Tropics region, from about 900 to 1,330 m altitude.
Helicia lamingtoniana, also named Lamington's silky oak, is a species of rainforest trees, of northeastern Queensland, Australia, from the flowering plant family Proteaceae.
Cnesmocarpon is a genus of 4 species of rainforest trees known to science, constituting part of the plant family Sapindaceae.
Dictyoneura is a genus of two-to-three species of rainforest trees known to science, constituting part of the plant family Sapindaceae.
Hollandaea riparia, sometimes named roaring Meg hollandaea, is a species of Australian rainforest tree, in the plant family Proteaceae.
Peripentadenia is a genus of two species of large trees from the family Elaeocarpaceae endemic to the rainforests of northeastern Queensland, Australia. Sometimes they have the common name quandong.
Syzygium forte, commonly known as white apple, flaky-barked satinash or brown satinash, is a tree of the family Myrtaceae native to Western Australia, the Northern Territory, Queensland and New Guinea.
Syzygium apodophyllum is a tree in the Myrtaceae family endemic to north Queensland. The fruit is edible. It is a host for the exotic plant-pathogen fungus Austropuccinia psidii, which is causing a lot of damage to vegetation communities and economic plants.
