Araucaria is familiar to many people as the genus of the distinctive conifer the Monkey-puzzle, A. araucana. The genus is named after the Arauco Indians of central Chile whose territory incorporates natural stands of this species, where it is known as the Pehu�n.

The genus has a highly disjunct distribution including such diverse regions as Argentina, Chile, southern Brazil, New Caledonia, Norfolk Island, Australia, and New Guinea. It appears from fossil records to have formerly existed also in the northern hemisphere with many if not all current populations being relict and restricted.

There are about 19 species in this small genus, some of which are relatively common in cultivation because of their distinctive, regimented growth habit. They include the Norfolk Island pine (A. heterophylla), the Monkey-puzzle or Chile Pine (A. araucana) and the Bunya-bunya (A. bidwillii).
