Alloxylon pinnatum.
Alloxylon pinnatum, the Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either lobed and up to 30 cm (12 in) long, or spear-shaped and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads with 50 to 140 individual flowers appear in spring and summer. These are followed by rectangular woody seed pods, which bear two rows of winged seeds. Known for many years as Oreocallis pinnata, it was transferred to the new genus Alloxylon by Peter Weston and Mike Crisp in 1991; the genus contains four species previously classified in Oreocallis that are found in Australasia. The tree's terminal tubular flowers indicate that it is pollinated by birds. Classified as "near threatened" under the Queensland Nature Conservation Act 1992, the Dorrigo waratah has proven difficult to keep alive in cultivation.
