[3] 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. It was most likely an accident that L'Héritier chose a feature common to all eucalypts. Although eucalypts must have been seen by the very early European explorers and collectors, no botanical collections of them are known to have been made until 1770 when Joseph Banks and Daniel Solander arrived at Botany Bay with Captain James Cook. The plantations are generally owned and operated for national and international industry by timber asset companies such as Thomson Forestry, Greenwood Management or cellulose producers such as Aracruz Cellulose and Stora Enso. iasLog("criterion : cdo_tc = resp"); A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalyptus, (genus Eucalyptus), large genus of more than 660 species of shrubs and tall trees of the myrtle family (Myrtaceae), native to Australia, Tasmania, and nearby islands.

The close correlation of these oils with other more potent toxins called formylated phloroglucinol compounds (euglobals, macrocarpals and sideroxylonals)[33] allows koalas and other marsupial species to make food choices based on the smell of the leaves. There is also an aesthetic argument for keeping the Eucalyptus; the trees are viewed by many as an attractive and iconic part of the California landscape.

[21][29][30] Eucalypts do well in a range of climates but are usually damaged by anything beyond a light frost of −5 °C (23 °F);[21][29][30] the hardiest are the snow gums, such as Eucalyptus pauciflora, which is capable of withstanding cold and frost down to about −20 °C (−4 °F). For them it represents the division of underworld, Earth and heaven. The account is the most important early systematic treatment of the genus. The Eucalyptus has been noted for its flammable properties and the large fuel loads in the understory of Eucalyptus forests. After the spiral phase, which may last from several to many nodes, the arrangement reverts to decussate by the absorption of some of the leaf-bearing faces of the stem. The contrast between juvenile and adult leaf phases is valuable in field identification. [20], There are more than 700 species of eucalyptus and most are native to Australia; a very small number are found in adjacent areas of New Guinea and Indonesia. In 1777, on Cook's third expedition, David Nelson collected a eucalypt on Bruny Island in southern Tasmania. Some species of eucalyptus drop branches unexpectedly.
