Araucaria araucana

Araucaria araucana, commonly called the pewen, monkey-puzzle, pehuen or piñonero or Chile pine, is an evergreen tree belonging to the family Araucariaceae and growing to a height of 30–40 m (98–131 ft) and a trunk diameter of 1–1.5 m (3.3–4.9 ft). Native to central and southern Chile and western Argentina, it is the hardiest species in the conifer genus Araucaria.

It is also the national tree of Chile and of the neighboring Argentine province of Neuquén. The IUCN changed its conservation status to Endangered in 2013, because logging, forest fires, and grazing have caused its population to dwindle.
