Eucalyptus oblique

 It comprises over 700-800 species, and accounts for more than two-thirds of Australia’s vegetation. They populate almost every habitat in Australia, from high snowy mountains to arid deserts to tropical rainforests. On warm days vaporised eucalyptus oil rises above the bush to create the characteristic distant blue haze of the Australian landscape. 

Many species yield valuable timber, others oils, kino, etc.
