Wikipedia: Eucalyptus is a genus of nearly nine hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is smooth, fibrous or stringy, leaves with oil glands, and sepals and petals that are fused to form a “cap” or operculum over the stamens. The fruit is a woody capsule commonly referred to as a “gumnut.” They are commonly known as eucalypts.
Members of the genus dominate the tree flora of Australia, and include Eucalyptus regnans, the tallest known flowering plant on Earth. Australia is covered by 92,000,000 hectares (227,336,951 acres) of eucalypt forest, comprising three quarters of the area covered by native forest.
Held annually on March 23, National Eucalypt Day aims to raise awareness of eucalypts and celebrate the important place that they hold in the hearts and lives of Australians.
