ABSTRACT
The Eucalyptus genus is a part of the myrtle family, which is a family of dicotyledon plants, that is, flowering plants. The seed of this family of plants typically contains two embryonic leaves or cotyledons. Eucalyptus trees are used primarily for their wood, and they also provide other products, including oil, which is used for a variety of industrial and pharmaceutical purposes. Eucalyptus can be found in almost every part of Australia, and the species is adapted to many different habitats. Eucalyptus is one of three similar genera that are commonly referred to as eucalypts, the other being Corymbia and Angophora. Eucalyptus oil at high concentration is poisonous, and it is also used as a pesticide. Several marsupials, such as koalas and some possums, are partly resistant to eucalyptus oil. A botanist, Sir Joseph Banks, was the first to introduce eucalyptus to other parts of the world on the Cook expedition in 1770.
