Araucaria heterophylla or A. excelsa is a distinctive conifer, a member of the ancient and now disjointly distributed family Araucariaceae. As its vernacular name Norfolk Island pine implies, the tree is endemic to Norfolk Island, a small island in the Pacific Ocean between Australia, New Zealand and New Caledonia. The genus Araucaria occurs across the South Pacific, especially concentrated in New Caledonia (about 700 km due north of Norfolk Island) where 13 closely related and similar-appearing species are found. It is sometimes called a star pine, triangle tree or living Christmas tree, due to its symmetrical shape as a sapling, although it is not a true pine.
