Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as Eucalyptus. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard 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".
Symbolism: The eucalyptus is a holy tree for the Aboriginals. For them, it represents the division of underworld, Earth and heaven. The eucalyptus leaf also has a purifying effect, as negative energy disappears in the place where you burn a eucalyptus leaf.
