Eucalyptus is the most common tree species in Australia. This name is derived from the Greek word meaning completely covered, referring to the shape of the fruit.

Eucalyptus is a large genus, with more than 600 species. It is native to Australia, but a few of it grows naturally in the Philippines, Malaysia, and the Pacific islands, especially the island of Taiwan, where the Taiwanese aromatic camphor Dryobalanops camphora forms real forests on its mountains; Its wood is used in the production of Taiwanese borneo camphor. Today, camphor forests are also spread over large areas in areas extending from southern Japan to Vietnam, and its cultivation is spread in Australia, California and Florida due to its industrial, economic and agricultural importance, and in the manufacture of furniture and drilling. Some American boys and girls still carry around their necks collars carrying small dangling bags containing camphor, as a protection against cold, or against physical ailment, or against psychological anxiety.
More than 200 species of eucalyptus have been cultivated in other countries, because it is a fast-growing, drought-tolerant wood tree. Eucalyptus is now a popular feature in landscaping in the USA, Portugal, East Africa, and parts of what was then the Soviet Union, on the Black Sea coast. Common types in western Europe include blue gum and cedar gum in Tasmania, the latter having its name from the scent of its leaves when rubbed. Eucalyptus trees are also planted in parks and gardens all over the world, for the beauty of their vegetation, flowers and seeds.
