Australia
The gum trees are almost as remarkable as the animals. They are mainly Eucalypts and other gum trees. These are woody evergeens which make essential oils and are prone to fire. Sticky heavily scented gum squeezes out of their wood. The tribe has about 860 species. They are all native to Southeast Asia and Oceania. Most live in Australia. Until British settlement in Australia, these trees were almost entirely unknown. They had been separated from the Americas, Africa and much of Asia for millions of years.
