Eucalyptus /ˌjuːkəˈlɪptəs/[2] L’Heritier 1789[3] is a diverse genus of flowering trees and shrubs (including a distinct group with a multiple-stem mallee growth habit) in the myrtle family, Myrtaceae. Eucalyptus is one of three similar genera that are commonly referred to as “eucalypts”, the others being Corymbia and Angophora. Many species, but far from all, are known as gum trees because they exude copious kino from any break in the bark (e.g., scribbly gum).
