Additional information

Habitat and botanical description

Eucalyptus globulus, native to Australia, is an evergreen tree in the Myrtaceae family that thrives mainly in warm regions. Its average height varies from 33 to 70 metres, making it one of the tallest trees in the world. Its trunk is covered with ash-grey bark. Its fragrant evergreen leaves are alternate, narrow and dark green, up to 35 cm long. They have secretory sacs that contain its essential oil. The flowers of Eucalyptus globulus are whitish and have numerous stamens. They are solitary, clustered at the base of the leaves.
The fruits are 1 to 2 cm in diameter and have a hard ovoid capsule containing tiny seeds. The shape of the fruit gives the variety its name, globulus.

Mythology / History / Anecdotes and traditional virtues

The name of the species Eucalyptus comes from the Greek "eu", beautiful, and "kalyptos", hidden, in connection with the calyx of the flower, which is in the form of a rigid capsule, the lid of which is released at the time of flowering. The variety "globulus" comes from "globus" (small ball), referring to the morphology of the fruit.
The vast expanses of Eucalyptus globulus forests have given Australia the nickname 'the land of blue mists'. Aboriginal people were probably the first to use Eucalyptus globulus to treat infections, particularly fever, hence one of its common names, 'fever tree'.
In the 19th century, it was planted in swampy areas of the subtropics to dry out the land, drain the soil and eradicate insects that carry diseases such as malaria. It was later planted in Spain for industrial purposes, to make paper pulp.
