Origin & History of “eucalyptus”
Europeans first encountered eucalyptus trees in Australia at the end of the 18th century. The French botanist Charles Louis l’Héritier based its Latin name, which he coined in 1788, on the fact that its flower buds have a characteristic conical cover (the Greek prefix eu- means ‘well’ and Greek kaluptós means ‘covered’).
