Corymbia tessellaris, commonly known as carbeen[2] or Moreton Bay ash,[3] is a species of tree that is endemic to north-eastern Australia.

The trunk is almost always straight, making up half to two thirds of the total tree height, with a crown of slender branches.

[2][4][5][6] Carbeen was first formally described in 1859 by Ferdinand von Mueller, who gave it the name Eucalyptus tessellaris in the Journal of the Proceedings of the Linnean Society, Botany.

[2][4][6] Yirrganydji and Djabugay people use medicine made from the tree to treat wounds and conditions such as dysentery, and use the wood to make tools.

The tree produces many organic compounds with industrial potential, including pinenes, aromadendrene, limonene and globulol.
