Other less commonly used names include Colonial Pine, Richmond River Pine, Queensland Pine, Alloa, Ningwik, or Pien, the wood is sometimes called Arakaria). It is named after botanist and explorer Allan Cunningham. The species is found in the coastal rain forests of eastern Australia and in New Guinea. The trees can live up to 450 years and grow to a height of 60 meters, it has a bark that is rough and splits naturally but does not peel.
The leaves on young trees are awl-shaped, 1-2 cm long, about 2 mm thick at the base, and scale-like, incurved, 1-2 cm long and 4 mm broad on mature trees. The cones are ovoid, 8-10 cm long and 6-8 cm diameter, and take about 18 months to mature. They disintegrate at maturity to release the nut-like edible seeds.
There are two varieties:
- Araucaria cunninghamii var. cunninghamii - Australia, from northeast New South Wales to east-central Queensland, at 0-1,000 m altitude.
- Araucaria cunninghamii var. papuana - New Guinea, on the mountains of Papua New Guinea, and in Irian Jaya, Indonesia, at 100-2,700 m altitude.
Cultivation and uses
The wood is a high quality timber that is particularly important to the plywood industry and also used for making furniture, veneer, joinery, turnery, and boats. Most natural stands in Australia and New Guinea have been depleted by logging. It is now mainly found on timber plantations. At one time, the resin was used by Australian Aborigines as a cement.
