Eucalypti is a term used to describe trees of the genus Eucalyptus. These tall evergreen trees are well-known for their aroma and oil, which is extracted for various purposes. Although eucalypti is a commonly used term, it may be interchanged with several synonyms such as eucalypt, gum, or jarrah trees. These synonyms are often used regionally, such as in Australia, where eucalypts are colloquially referred to as gum trees for the gummy sap they produce. In addition, the term eucalypti may also refer to the leaves of the tree, which are used for medicinal and therapeutic purposes, and can be replaced with synonyms like eucalyptus leaves or gum leaves.
