Alloxylon

Alloxylon is a genus of four species in the family Proteaceae of mainly small to medium-sized trees. They are native to the eastern coast of Australia, with one species, A. brachycarpum, found in New Guinea and the Aru Islands. The genus is a relatively new creation, being split off from Oreocallis in 1991. The name is derived from Ancient Greek "other" or "strange" and or "wood" due to their unusual cell architecture compared with the related genera Telopea and Oreocallis. In Australia, they are known as tree waratahs due to similarities in the inflorescences between them and the closely related Telopea.

==Classification== Together with Telopea, Oreocallis and Embothrium, Alloxylon makes up a small group of terminal often red-flowering showy plants scattered around the southern edges of the Pacific Rim. Known as the subtribe Embothriinae, this is an ancient group with roots in the mid Cretaceous, when Australia, Antarctica and South America were linked by land.
