Araucaria hunsteinii (Klinki , Klinkii or "Klinky", native names Rassu and Pai[ citation needed]) is a species of Araucaria native to the mountains of Papua New Guinea. It is threatened by habitat loss.
It is a very large evergreen tree (the tallest in New Guinea, and the tallest species in its family), growing to 50–80 metres (164–262 ft) tall, exceptionally to 90 metres (295 ft), with a trunk up to 3 metres (10 ft) diameter. The branches are horizontal, produced in whorls of five or six. The leaves are spirally arranged, scale-like or awl-like, 6–12 centimetres (2–5 in) long and 1.5–2 centimetres (5⁄8–3⁄4 in) broad at the base, with a sharp tip; leaves on young trees are shorter (under 9 centimetres (4 in)) and narrower (under 1.5 centimetres (5⁄8 in)). It is usually monoecious with male and female cones on the same tree; the pollen cones are long and slender, up to 20 centimetres (8 in) long and 1 centimetre (3⁄8 in) broad; the seed cones are oval, up to 25 centimetres (10 in) long and 14–16 centimetres (5+1⁄2–6+1⁄4 in) broad. The seed cones disintegrate at maturity to release the numerous 3–4 centimetres (1–1+1⁄2 in) long nut-like seeds.
It is a fast-growing tree, and is being tested as a potentially important timber crop in tropical highland climates.
Barinae spp., [Gray 1] Setomorpha rutella, [Gray 2] Microlepidopteras, [Gres. 1] 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. [Gres. 2] However, another source describes A. hunsteinii as suffering few pests in plantations, and therefore substituting A. cunninghamii in plantations that suffer more from pests. [2]
