Alloxylon is a genus of four species in the Proteaceae family 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. The name is derived from Ancient Greek allo- "other" or "strange" and xylon or "wood" due to their unusual cell architecture compared with the related genera Telopea and Oreocallis.
