Araucaria hunsteinii mature trunk detail.

It is a very large evergreen tree (the tallest in New Guinea, and the tallest species in its family), growing to Шаблон:Convert tall, exceptionally to Шаблон:Convert, with a trunk up to Шаблон:Convert diameter. The branches are horizontal, produced in whorls of five or six. The leaves are spirally arranged, scale-like or awl-like, Шаблон:Convert long and Шаблон:Convert broad at the base, with a sharp tip; leaves on young trees are shorter (under Шаблон:Convert) and narrower (under Шаблон:Convert). It is usually monoecious with male and female cones on the same tree; the pollen cones are long and slender, up to Шаблон:Convert long and Шаблон:Convert broad; the seed cones are oval, up to Шаблон:Convert long and Шаблон:Convert broad. The seed cones disintegrate at maturity to release the numerous Шаблон:Convert long nut-like seeds.

Cultivation and usesШаблон:Anchor

It is a fast-growing tree, and is being tested as a potentially important timber crop in tropical highland climates.

Pests

Barinae spp., Setomorpha rutella, Microlepidopteras, Cacatua galerita (the Sulphur-crested cockatoo) are pests of pine nut production in A. hunsteinii. C. galerita may cause half of the seed crop to be lost in a year, mostly by trying to eat cones that are not yet ready. However, another source describes A. hunsteinii as suffering few pests in plantations, and therefore substituting A. cunninghamii in plantations that suffer more from pests.
