Araucaria is a genus of evergreen coniferous trees in the family Araucariaceae. There are 19 extant species in the genus, with a Gondwanan natural distribution in New Caledonia (where 13 species are endemic), Norfolk Island, eastern Australia, New Guinea, Argentina, Chile, and southern Brazil. The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree, Araucaria araucana. No distinct vernacular name exists for the genus. Many are called “pine”, although they are only distantly related to true pines, in the genus Pinus.

Araucaria cunninghamii is a species of Araucaria known as hoop pine. Other less commonly used names include colonial pine, Queensland pine, Dorrigo pine, Moreton Bay pine and Richmond River pine. The scientific name honours the botanist and explorer Allan Cunningham, who collected the first specimens in the 1820s. The species is found in the dry rainforests of New South Wales and Queensland and in New Guinea. The trees can live up to 450 years and grow to a height of 60 metres. The barough, splits naturally, and peels easily. The leaves on young trees are awl-shaped, 12 cm long, about 2 mm thick at the base, and scale-like, incurved, 12 cm long and 4 mm broad on mature trees. The cones are ovoid, 810 cm long and 68 cm diameter, and take about 18 months to mature. They disintegrate at maturity to release the nut-like edible seeds. The wood is a high quality timber that is particularly important to the plywood industry and also used for furniture, veneer, joinery, panelling, particle board, flooring and boats. Most natural stands in Australia and Papua New Guinea have been depleted by logging. It is now mainly found on timber plantations; however, the species continues to thrive in protected areas, including Lamington National Park where at least one walking track is named after it.
