== Taxonomy ==
'''Eucalyptus globulus''', commonly known as the [[Tasmanian blue gum]], is a species of [[evergreen]] tree native to southeastern [[Australia]]. It is one of the most widely cultivated trees native to Australia, grown in temperate regions worldwide.
The species was first formally described by the French botanist [[Jacques Labillardière]] in his 1800 work, ''Relation du Voyage à la Recherche de la Pérouse''. The specific epithet (''globulus'') is derived from the Latin ''globulus'', a little button or small sphere, referring to the shape of the operculum.


== Description ==
==Description==
'''Eucalyptus globulus''' is a tree that typically grows to a height of 45 m (148 ft) but can reach 90 m (300 ft). Young plants and coppice regrowth have sessile leaves arranged in opposite pairs, lance-shaped to egg-shaped, up to 150 mm (5.9 in) long and 70 mm (2.8 in) wide. Adult leaves are arranged alternately, the same glossy green on both sides, lance-shaped to curved, 150–300 mm (5.9–11.8 in) long and 17–30 mm (0.67–1.18 in) wide on a petiole 15–35 mm (0.59–1.38 in) long.

Eucalyptus globulus is a tall, evergreen tree that can grow up to 70 meters in height. The bark is smooth, shedding in long strips. The leaves are glossy, dark green, and lance-shaped. Juvenile leaves are opposite, sessile, and glaucous, while adult leaves are alternate and petiolate.

==Subspecies==
'''Eucalyptus globulus''' is native to the state of [[Tasmania]], Australia. It is found on subalpine areas where it is dominant in wet forests and rainforests on fertile soils in cool humid climates.
There are four recognized subspecies of Eucalyptus globulus:


== Uses ==
* '''Eucalyptus globulus subsp. globulus'''
The tree's leaves are steam distilled to extract [[Eucalyptus oil]]. E. globulus is the primary source of global eucalyptus oil production, with China being the largest commercial producer. The oil has therapeutic, perfumery, flavoring, antimicrobial and biopesticide properties.
* '''Eucalyptus globulus subsp. bicostata'''
* '''Eucalyptus globulus subsp. maidenii'''
* '''Eucalyptus globulus subsp. pseudoglobulus'''


== Conservation ==
