Eucalypts are woody plants belonging to three closely related genera:
Eucalyptus is a diverse genus of flowering trees in the myrtle family, Myrtaceae. Members of the genus dominate the tree flora of Australia...

, Corymbia
Corymbia is a genus of about 113 species of tree that were classified as Eucalyptus species until the mid-1990s. It includes the bloodwoods, ghost gums and spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse Eucalyptus genus since 1867...

and Angophora
Angophora is a genus of ten species of trees or large shrubs in the myrtle family , native to eastern Australia. It is closely related to Corymbia and Eucalyptus, and all three are often referred to as "eucalypts". The differences are that Angophora have opposite leaves rather than alternate, and...


In 1995 new evidence, largely genetic, indicated that some prominent Eucalyptus species were actually more closely related to Angophora than to the other eucalypts; they were split off into the new genus Corymbia. Although separate, the three groups are allied and it remains acceptable to refer to the members of all three genera Angophora, Corymbia and Eucalyptus as "eucalypts"


Eucalypts are attuned to withstand fire in several ways:
  • Their seeds are often held in an insulated capsule, which is only opened in response to and after the devastation of a bushfire
    Bushfires in Australia
    Bushfires in Australia are frequently occurring events during the hotter months of the year due to Australia's mostly hot, dry climate. Large areas of land are ravaged every year by bushfires, which also cause property damage and loss of life....

    . Once cooled down, it is a freshly fertilised seed bed.
  • Oils in the leaves tend to make the fire more severe and therefore more damaging to less attuned species.
  • Epicormic buds

    An epicormic shoot is a shoot growing from an epicormic bud which lies underneath the bark of a trunk, stem, or branch of a plant.-Epicormic buds:...

     under the often thick bark
    Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines and shrubs. Bark refers to all the tissues outside of the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner...

     of the trunk
    Trunk (botany)
    In botany, trunk refers to the main wooden axis of a tree that supports the branches and is supported by and directly attached to the roots. The trunk is covered by the bark, which is an important diagnostic feature in tree identification, and which often differs markedly from the bottom of the...

These advantages work well in areas affected by long dry spells.

There are over 700 species of Eucalypt that dominates landscapes all over Australia, but it is reduced in diversity in the rainforests and arid envrironments.
