Pehuen, Monkey-puzzle (from the notion that the overlapping sharply-pointed scales covering the branches would provide a "puzzle" to any monkey attempting to climb it!)

"Araucaria araucana (Pehuén or Monkey-puzzle) is the hardiest species in the conifer genus Araucaria. It is native to central Chile and west central Argentina, and is an evergreen tree growing to 40 m tall and 2 m trunk diameter. Because of the species' great age it is sometimes described as a living fossil. Araucaria araucana is the national tree of Chile.
"Araucaria is a genus of evergreen coniferous trees in the family Araucariaceae. There are 19 species in the genus, with a highly disjunct distribution in New Caledonia (where 13 species are endemic), Norfolk Island, eastern Australia, New Guinea, Argentina, Chile, and southern Brazil.
"Araucaria are mainly large trees with a massive erect stem, reaching a height of 30-80 m. The horizontal, spreading branches grow in whorls and are covered with leathery or needle-like leaves. In some species, the leaves are narrow awl-shaped and lanceolate, barely overlapping each other, in others they are broad and flat, and overlap broadly.
"The trees are mostly dioecious, with male and female cones found on separate trees, though occasional individuals are monoecious or change sex with time. The female cones, usually high on the top of the tree, are globose, and vary in size between species from 7-25 cm diameter. They contain 80-200 large, edible seeds, similar to pine nuts though larger. The male cones are smaller, 4-10 cm long, and narrow to broad cylindrical, 1.5-5 cm broad.
"Many if not all current populations are relicts, and of restricted distribution. They are found in forest and maquis shrubland, with an affinity for exposed sites. These columnar trees are living fossils, dating back to early in the Mesozoic age. Fossil records show that the genus also formerly occurred in the northern hemisphere until the end of the Cretaceous period." (Wikipedia)

Araucaria araucana (popularly called the Monkey-puzzle Tree or Monkey Tail Tree) is an evergreen tree growing to 40 metres (130 ft) tall with a 2 metres (7 ft) trunk diameter. The tree is native to central and southern Chile, western Argentina and south Brazil. Araucaria araucana is the hardiest species in the conifer genus Araucaria. Because of the species's great age it is sometimes described as a living fossil.
Araucaria araucana is the national tree of Chile.
Araucaria is a genus of evergreen coniferous trees in the family Araucariaceae. There are 19 extant species in the genus, with a highly disjunct distribution in New Caledonia (where 13 species are endemic), Norfolk Island, eastern Australia, New Guinea, Argentina, Chile, and southern Brazil.
Araucariaceae, commonly referred to as araucarians, is a very ancient family of coniferous trees. It achieved its maximum diversity in the Jurassic and Cretaceous periods, when it was distributed almost worldwide. At the end of the Cretaceous, when dinosaurs became extinct, so too did the Araucariaceae in the northern hemisphere.
