Eucalyptus is a genus of over seven hundred species of flowering trees. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy. The fruit is a woody capsule commonly referred to as a “gumnut”.
Most species of Eucalyptus are native to Australia, and every state and territory has representative species. A few species are native to other countries and a smaller number are only found outside Australia. Eucalypts have been grown in plantations in many other countries because they are fast growing and have valuable timber, or can be used for pulpwood, for honey production or essential oils. In some countries, however, they have been removed because they are highly flammable.
