As a generalisation “forest trees” are single-stemmed and have a crown forming a minor proportion of the whole tree height. Woodland trees” are single-stemmed, although they may branch at a short distance above ground level. Many mallee trees may be so low-growing as to be considered a shrub. Two other tree forms are notable in Western Australia and described using the native names “mallet” and “marlock”. Forest Trees of Australia, it is defined as a small tree without lignotubers, but with a shorter, lower-branching trunk than a mallet. They usually grow in more or less pure stands.

The term “morrell” is somewhat obscure in origin and appears to apply to trees of the western Australian wheatbelt and goldfields which have a long, straight trunk, completely rough-barked. It is now used mainly for E. Nearly all eucalyptus are evergreen, but some tropical species lose their leaves at the end of the dry season. As in other members of the myrtle family, eucalyptus leaves are covered with oil glands. The copious oils produced are an important feature of the genus. The leaves on a mature eucalyptus plant are commonly lanceolate, petiolate, apparently alternate and waxy or glossy green. However, no definite transitional point occurs between the phases.
The intermediate phase, when the largest leaves are often formed, links the juvenile and adult phases. In some narrow-leaved species, for example E. The appearance of eucalyptus bark varies with the age of the plant, the manner of bark shed, the length of the bark fibres, the degree of furrowing, the thickness, the hardness, and the colour. All mature eucalypts put on an annual layer of bark, which contributes to the increasing diameter of the stems. This allows the tree to grow in less-than-ideal climates, in addition to providing a better chance of recovery from damage sustained to its leaves in an event such as a fire. Stringybark — consists of long fibres and can be pulled off in long pieces. It is usually thick with a spongy texture. Ironbark — is hard, rough, and deeply furrowed. Tessellated — bark is broken up into many distinct flakes.
They are corkish and can flake off. Ribbon — has the bark coming off in long, thin pieces, but is still loosely attached in some places. They can be long ribbons, firmer strips, or twisted curls. The extraordinary coloured bark of E. The dark, fissured ‘ironbark’ of E. The oldest definitive Eucalyptus fossils are surprisingly from South America, where eucalypts are no longer endemic, though have been introduced from Australia. Laguna del Hunco deposit in Chubut province in Argentina. Cenozoic, and suggests that this rise to dominance is a geologically more recent phenomenon.

In more recent sediments, numerous findings of a dramatic increase in the abundance of Eucalyptus pollen are associated with increased charcoal levels. List of Eucalyptus species for a comprehensive list of species. Hybrid individuals have not always been recognised as such on first collection and some have been named as new species, such as E.
Hybrid combinations are not particularly common in the field, but some other published species frequently seen in Australia have been suggested to be hybrid combinations. A small genus of similar trees, Angophora, has also been known since the 18th century. Several eucalypt species are among the tallest trees in the world. Most eucalypts are not tolerant of severe cold. An essential oil extracted from eucalyptus leaves contains compounds that are powerful natural disinfectants and can be toxic in large quantities. Several marsupial herbivores, notably koalas and some possums, are relatively tolerant of it.
