The bunya pine (Araucaria bidwillii Hook) is one of the most interesting species of the family Araucariaceae, a typical Southern Hemisphere conifer (Table 1) family that includes three living genera: Araucaria de Jussieu, Agathis Salisbury and the recently described genus Wollemia Jones, Hill and Allen. Araucaria bidwillii is traditionally classified in the Section Bunya of genus Araucaria. In addition to the section Bunya, there are three more sections in the genus Araucaria: Eutacta Endlicher and Intermedia White from Australasia, and Araucaria (=Columbea) Wilde and Eames from South America.
