Athertonia is a genus of tall trees, constituting part of the plant family Proteaceae. It is a monotypic taxon, and the sole described species is Athertonia diversifolia, commonly known as Atherton oak. It is a small to medium-sized tree and is endemic to restricted tablelands and mountainous regions of the wet tropics rain forests of north-eastern Queensland, Australia, where it is widespread. For example, it grows in the Atherton Tableland region with which it shares its name, from the colonial pastoralist John Atherton (1837–1913). Its closest relatives are Heliciopsis and Virotia. A relative of the macadamia, it has potential as an ornamental tree and has an edible nut.
Triunia is a genus of medium to tall shrubs or small trees found as understorey plants in rainforests of eastern Australia. Members of the plant family Proteaceae, they are notable for their poisonous fleshy fruits or drupes. Only one species, T. youngiana, is commonly seen in cultivation.
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.
Helicia australasica, also named Austral oak or creek silky oak, is a species of rainforest trees from the flowering plant family Proteaceae.
Stenocarpus cryptocarpus, commonly known as the giant-leaved stenocarpus, is a species of flowering plant in the family Proteaceae and is endemic to north Queensland. It is a tree with buttress roots at the base, simple, mostly elliptical adult leaves, groups of cream-coloured flowers and narrow oblong follicles.
Eidothea zoexylocarya is a species of tall rainforest trees endemic to north-eastern Queensland, Australia and constituting part of the plant family Proteaceae. In European–Australian science, these trees were only recognised in recent decades, first from the slopes of Mount Bartle Frere, the Queensland mountain which reaches the highest altitude. In 1995, scientific descriptions of the trees, as this genus and type species, were published for the first time by Andrew W. Douglas and Bernie Hyland. The species name refers to the almost identical fossil fruit Xylocaryon lockiiF.Muell., from Ballarat, southern Australia, still extant in this north-eastern Australian species.
Darlingia ferruginea, commonly known as the brown silky oak, is a rainforest tree of the family Proteaceae from Northern Queensland.
Buckinghamia celsissima, commonly known as the ivory curl tree, ivory curl flower or spotted silky oak, is a species of tree in the family Proteaceae. It is endemic to the tropical rainforests of northeastern Queensland, Australia.
Xylomelum cunninghamianum is a species of flowering plant in the family Proteaceae and is endemic to eastern Australia. It is a shrub or small tree with narrow elliptic to lance-shaped leaves with toothed edges when young, groups of flowers covered with brownish hairs and oval fruit densely covered with velvety rust-coloured to grey hair.
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.
Opisthiolepis is a genus of a sole described species of large trees, constituting part of the plant family Proteaceae. The species Opisthiolepis heterophylla most commonly has the names of blush silky oak, pink silky oak, brown silky oak and drunk rabbit.
Placospermum is a genus of a single species of large trees, constituting part of the plant family Proteaceae. The species Placospermum coriaceum is endemic to the rainforests of the wet tropics region of northeastern Queensland, Australia. Common names include rose silky oak and plate-seeded oak.
Sphalmium is a monotypic genus of flowering plants in the protea family. The only species, Sphalmium racemosum, is a large forest tree. Common names include satin silky oak, mystery oak, Mt Lewis oak, poorman's fishtail oak and buff silky oak.
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.
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.
Stenocarpus verticis is a species of flowering plant in the family Proteaceae and is endemic to northern Australia. It is a tree with elliptic or lance-shaped adult leaves and groups of cream-coloured flowers covered with woolly, rust-coloured or grey hairs.
Stenocarpus davallioides, commonly known as the fern-leaved stenocarpus, is a species of flowering plant in the family Proteaceae and is endemic to north Queensland. It is a tree with simple or pinnate adult leaves, groups of creamy-green flowers and narrow oblong follicles.
Don Foreman was an Australian botanist who worked on the Monimiaceae and Proteaceae of Australia. He also helped with the editing of selected Flora of Victoria and Flora of Australia Volumes.
Austromuellera valida is a species of rainforest tree in the protea family that is endemic to north-eastern Queensland, Australia. It was first formally described by Bernard Hyland in 1999 in the series Flora of Australia.
