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.

The leaves are spirally arranged, scale-like or awl-like, 6–12 centimetres (2–5 in) long and 1.5–2 cm (5⁄8–3⁄4 in) broad at the base, with a sharp tip; leaves on young trees are shorter (under 9 cm or 4 in) and narrower (under 1.5 cm or 5⁄8 in).

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

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.
