Corymbia is a genus of about 113 species of tree that were classified as
Eucalyptus species until the mid-1990s. It includes the
bloodwoods,
ghost gums and
spotted gums. The bloodwoods had been recognised as a distinct group within the large and diverse
Eucalyptus genus since 1867. Molecular research in the 1990s, however, showed that they, along with the rest of the Corymbia section, are more closely related to
Angophora than to
Eucalypt
