Eucalypts
Family Myrtaceae
Eucalyptus sp., eucalypts (E. globulus 1), is a large genus of shrubs and trees, characteristic for the Australian flora. The leaves are simple, usually entire and opposite or alternate, finely dotted with oil glands. The flowers are regular, with the perianth united to form a little lid that burst open when the flowers open, showing the numerous stamens (E. globulus 2). The fruit is usually a woody capsule (E. globulus 3).
Use
Two species have been introduced into most tropical countries: Eucalyptus globulus, blue gum, and Eucalyptus saligna. Both are fast growing trees, providing timber and firewood. Eucalyptus oil is distilled from the leaves and is used medically in inhalants, sprays and gargles, disinfectants and the like; and for industrial purposes as a source of piperitone from which thymol and menthol are manufactured.
