Eucalyptus × tetragona

Eucalyptus × tetragona is a hybrid species in the genus Eucalyptus. The valid taxonomic name Eucalyptus tetragona was previously used to describe the species now known as Eucalyptus pleurocarpa, but the type specimen upon which the name was based turned out to be a hybrid with E. extrica, so the later homonym E. pleurocarpa was adopted for the pure species, and E. × tetragona for the hybrid. The Noongar names for the tree are Talyerock or Tallerack.

Entries in earlier texts The West Australian Flora and Eucalypts of the Western Australian goldfields (and the adjacent wheatbelt) have the earlier assumption of the separate non hybrid form.
