The name Eucalyptus, from the Greek words eu-, well, and kaluptos, cover, meaning "well-covered", describes the operculum.
Nearly all eucalyptuses are evergreen, leaves are covered with oil glands. The copious oils produced are an important feature of the genus, waxy or glossy green. Eucalyptus was introduced from Australia to the rest of the world following the Cook expedition in 1770.
The green eucalyptus is a medium length stem: 50-60 cm. A finecut is made up of 10 stems.
