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 is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
Helicia australasica, also named Austral oak or creek silky oak, is a species of rainforest trees from the flowering plant family Proteaceae.
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.
Helicia glabriflora is a species of rainforest shrubs or small trees occurring in eastern Australia. Common names include smooth or pale helicia, pale, leather or brown oak. They grow naturally in a variety of different rainforest types from the Illawarra, New South Wales to the Townsville area, Queensland. Of all the global diversity of approximately one hundred Helicia species, this one species naturally grows the furthest south, in the Minnamurra Rainforest and the Robertson area, Illawarra, New South Wales, there observed more on the relatively fertile basalt and alluvial soils.
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.
Catalepidia is a genus of a sole described species of medium-sized trees, constituting part of the plant family Proteaceae. The species Catalepidia heyana grows naturally only in a restricted mountain region (endemic) of the wet tropics rain forests of north-eastern Queensland, Australia. Common names include Hey's nut or Hey's nut 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 ferruginea, commonly named hairy honeysuckle or rusty oak, is a species of rainforest trees, of eastern Australia, from the flowering plant family Proteaceae.
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.
Helicia nortoniana, also named Norton's silky oak, 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.
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.
Buckinghamia ferruginiflora, also known as Noah's oak or spotted oak, is a species of rainforest tree in the protea family, one of two in the genus that is endemic to the Wet Tropics of Queensland, north-eastern Australia. Although the tree's differences from its congener had been known since the 1970s, it was only formally described by Donald Foreman and Bernard Hyland in 1988 in the journal Muelleria.
