Romnalda is a genus of monocotyledonous plants in the family Asparagaceae, subfamily Lomandroideae. As of December 2013 four formally named species are known and accepted by botanical science.
Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, B. celsissima, is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, B. ferruginiflora, was only recently described in 1988.
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.
Romnalda ophiopogonoides is a vulnerable species of flowering lily plants endemic to a restricted area of the Wet Tropics of Queensland. In the wild, it has only been found in a few isolated locations in the vicinity of Cooper Creek.
Gymnostoma australianum, commonly known as the Daintree pine or Daintree oak, is a species of small tree which is endemic to a restricted area of the Daintree tropical rainforests region, within the Wet Tropics of north-eastern Queensland, Australia. It is a member of the plant family Casuarinaceae, often named she-oaks, members of which are characterised by drooping equisetoid evergreen foliage, and separate male and female flowers (unisexual). Superficially they look like well known scale–leaved gymnosperm trees species, such as Cupressus in the northern hemisphere and Callitris in the southern hemisphere.
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.
Lasjia is a genus of five species of trees of the family Proteaceae. Three species grow naturally in northeastern Queensland, Australia and two species in Sulawesi, Indonesia. Descriptively they are the tropical or northern macadamia trees group. Lasjia species characteristically branched compound inflorescences differentiate them from the Macadamia species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about 1,000 km (620 mi) further to the south, in southern and central eastern Queensland and in northeastern New South Wales.
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.
Mischarytera is a genus of rainforest trees, constituting part of the plant family Sapindaceae. Four species are known to science as of December 2013, found growing naturally in eastern Queensland, Australia, and in New Guinea. Formerly until 1995, they had names within the genus Arytera, subgenus Mischarytera.
Canarium acutifolium is a forest tree species, of the plant family Burseraceae, growing naturally in New Guinea, the Moluccas, Sulawesi, New Britain, New Ireland, Bougainville and in lowland north-eastern Queensland, Australia.
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 grayi, also named Gray's silky oak, is a species of rainforest trees, of northeastern Queensland, Australia, from the flowering plant family Proteaceae.
Helicia lamingtoniana, also named Lamington's silky oak, is a species of rainforest trees, of northeastern Queensland, Australia, from the flowering plant family Proteaceae.
Helicia recurva is a species of rainforest trees, of northeastern Queensland, Australia, from the flowering plant family Proteaceae.
Hollandaea sayeriana, sometimes named Sayer's silky oak, is a small species of Australian rainforest trees in the plant family Proteaceae.
Hollandaea riparia, sometimes named roaring Meg hollandaea, is a species of Australian rainforest tree, in the plant family Proteaceae.
Hollandaea diabolica is a species of Australian rainforest tree, constituting part of the plant family Proteaceae. It is endemic to restricted areas of the rainforests of the Wet Tropics region of northeastern Queensland.
Hollandaea porphyrocarpa is a species of small Australian rainforest tree in the plant family Proteaceae. It is endemic to restricted areas of the rainforests of the Wet Tropics region of northeastern Queensland.
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.
Lindsayomyrtus is a monotypic genus in the family Myrtaceae, containling the single species Lindsayomyrtus racemoides, commonly known as Daintree penda. These large trees grow naturally in the rainforests of the Wet Tropics of Queensland in Australia, the Moluccas, New Guinea and New Britain.
