Hybrid individuals have not always been recognised as such on first collection and some have been named as new species, such as "E. chrysantha" ("E. preissiana" × "E. sepulcralis") and "E." "rivalis" ("E. marginata" × "E. megacarpa"). Hybrid combinations are not particularly common in the field, but some other published species frequently seen in Australia have been suggested to be hybrid combinations. For example, "E. erythrandra" is believed to be "E. angulosa" × "E. teraptera" and due to its wide distribution is often referred to in texts.
