Araucaria Araucana Tree. A new tree to me. Lovely uplifted branches. Araucaria araucana (Monkey puzzle tree) 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.
