Tasmanian oak

Tasmanian oak refers to the hardwood produced by three trees: "Eucalyptus regnans", "Eucalyptus obliqua" or "Eucalyptus delegatensis", when it is sourced from the Australian state of Tasmania.
Despite the common name 'oak', none of the species are in the genus Quercus.
The hardwood timber is light-coloured, ranging from straw to light reddish brown. 
It is used in construction, including panelling and flooring, for furniture, and also for reconstituted board and high quality paper. 
When sourced from Victoria, the wood of "Eucalyptus regnans" and "Eucalyptus delegatensis" is called Victorian ash. 
The species are also widely known by their common names. "Eucalyptus obliqua" is known as stringybark or messmate, "Eucalyptus regnans" is known as mountain ash, and the closely related "Eucalyptus delegatensis "is known as alpine ash or woollybutt.
