Araucaria araucana (commonly called the monkey puzzle tree, monkey tail tree, Chilean pine, or pehuén) is an evergreen tree growing to Script error: No such module "convert". tall with a 2-m (7-ft) trunk diameter. The tree is native to central and southern Chile and western Argentina. Araucaria araucana is the hardiest species in the conifer genus Araucaria. Because of the great age of this species, it is sometimes described as a living fossil. Its conservation status was changed to Endangered by the IUCN in 2013 due to its declining abundance.
It is the national tree of Chile.
The leaves are thick, tough, and scale-like, triangular, Script error: No such module "convert". long, Script error: No such module "convert". broad at the base, and with sharp edges and tips. They persist for 10–15 years or more, so cover most of the tree except for the older branches.
This tree is usually dioecious, with the male and female cones on separate trees, though occasional individuals bear cones of both sexes. The male (pollen) cones are oblong and cucumber-shaped, Script error: No such module "convert". long at first, expanding to Script error: No such module "convert". long by Script error: No such module "convert". broad at pollen release. The tree is wind pollinated. The female (seed) cones, which mature in autumn about 18 months after pollination, are globose, large, Script error: No such module "convert". in diameter, and hold about 200 seeds. The cones disintegrate at maturity to release the Script error: No such module "convert". long nut-like seeds.
Its native habitat is the lower slopes of the Chilean and Argentinian south-central Andes, typically above Script error: No such module "convert".. Juvenile trees exhibit a broadly pyramidal or conical habit which naturally develops into the distinctive umbrella form of mature specimens as the tree ages. It prefers well-drained, slightly acidic, volcanic soil, but will tolerate almost any soil type provided it drains well.
Cultivation and uses
Araucaria araucana is a popular garden tree, planted for its unusual effect of the thick, "reptilian" branches with a very symmetrical appearance. It prefers temperate climates with abundant rainfall, tolerating temperatures down to about -20 °C (-4 °F). It is far and away the hardiest member of its genus, and can grow well in western Europe (north to the Faroe Islands and Smøla in western Norway), the west coast of North America (north to the islands of Haida Gwaii in Canada), and locally on the east coast, as well as Long Island, and in New Zealand and southeastern Australia. It is tolerant of coastal salt spray, but does not tolerate exposure to pollution.
Its seeds are edible, similar to large pine nuts, and are extensively harvested in Chile. The tree has some potential to be a food crop in other areas in the future, thriving in climates with cool oceanic summers, e.g., western Scotland, where other nut crops do not grow well. A group of six female trees with one male for pollination could yield several thousand seeds per year. Since the cones drop, harvesting is easy. The tree, however, does not yield seeds until it is around 30 to 40 years old, which discourages investment in planting orchards (although yields at maturity can be immense); once established, it can live possibly as long as 1,000 years. Once valued because of its long, straight trunk, its current rarity and vulnerable status mean its wood is now rarely used; it is also sacred to some members of the Mapuche Native American tribe. Before the tree became protected by law in 1971, lumber mills in Araucanía Region specialized in Chilean pine. This species is listed in the CITES Appendix I as an endangered species.
Discovery and naming
First found in Chile in the 1780s, it was named Pinus araucana by Molina in 1782. In 1789, de Jussieu had erected a new genus called Araucaria based on the species, and in 1797, Pavón published a new description of the species which he called Araucaria imbricata (an invalid name, as it did not use Molina's older species epithet). Finally, in 1873, after several further redescriptions, Koch published the combination Araucaria araucana, validating Molina's name in the genus. The name araucana is derived from the native Araucanians who used the nuts (seeds) of the tree in Chile. A group of Araucanians living in the Andes, the Pehuenches, owe their name to their diet based on harvesting of the A. araucaria seeds. Pehuen means Araucaria and che means people in Mapudungun.
The origin of the popular English language name 'monkey puzzle' derives from its early cultivation in Britain in about 1850, when the species was still very rare in gardens and not widely known. Sir William Molesworth, the proud owner of a young specimen at Pencarrow garden near Bodmin in Cornwall was showing it to a group of friends, one of them – the noted barrister and Benthamist Charles Austin remarked, "It would puzzle a monkey to climb that". As the species had no existing popular name, first 'monkey puzzler', then 'monkey puzzle' stuck. This reference led to the use of the pseudonym "Araucaria" by a late British crossword compiler for The Guardian newspaper, The Reverend John Galbraith Graham MBE (1921–2013), who also provided cryptic crosswords under the pseudonym Cinephile—an anagram of "Chile Pine" the tree's alternate name—in the Financial Times and puzzles for other publications
In France, it is known as désespoir des singes or 'monkeys' despair'.
The nearest relative found is Araucaria angustifolia, a South American Araucaria which differs in the width of the leaves. The recently found 'Wollemi pine', Wollemia, though discovered in south-east Australia, is possibly its relative or possibly a relative of the Norfolk Island pine. Their common ancestry dates to a time when Australia, Antarctica, and South America were linked by land.

In the 1947 20th Century Fox film, 'The Ghost and Mrs. Muir', the ghost in the film, former sea captain Daniel Gregg, (Rex Harrison), has a monkey puzzle tree growing in the front yard of his seaside house. Lucy Muir, (Gene Tierney), after moving into the house as a tenant, has it cut down for firewood, thinking that it spoils the view of the sea, and that rose bushes would be better. This infuriates the ghost who states that he had planted the tree with his own hands because he had always wanted to have a monkey puzzle tree. It's a plausible assumption that the writer of the story (Philip Dunne adapting from the Josephine Leslie novel written as R.A. Dick) chose a monkey puzzle tree, known for its gnarly exterior and as a living fossil, to represent similar characteristics to Captain Gregg.
In the novel Charlotte Sometimes by Penelope Farmer, the sisters Charlotte/Clare and Emily are given lodgings in a house with a monkey-puzzle tree in the garden. Rambunctious Emily immediately plans and later manages to climb the tree; the sisters later learn that Arthur, the younger son of their lodging parents who recently died in World War I, as a boy also climbed the tree but grew scared and could not climb down again.
