who gave it the name ''Eucalyptus globulus'' var. ''pseudoglobulus'' and published the description in his book ''Description and emploi des Eucalyptus: introduits en Europe principalement en France et en Algerie: second memoire''. In 1974, James Barrie Kirkpatrick described four subspecies, including changing the name of ''E. globulus'' var. ''pseudoglobulus'' to ''E. globulus'' subsp. ''pseudoglobulus''.
