specimens near Wigton. In 1995, Ken Hill and Lawrie Johnson changed the name to ''Corymbia watsoniana'', publishing the change in the journal '' Telopea''.
In the same paper, Hill and Johnson described two subspecies and the names have been accepted by the Australian Plant Census:
* ''Corymbia watsoniana'' subsp. ''capillata'' (Brooker & A.R.Bean) K.D.Hill & L.A.S.Johnson has bristly late juvenile and intermediate leaves with the petiole attached to the underside of the leaf blade;
* ''Corymbia watsoniana'' (F.Muell.) K.D.Hill & L.A.S.Johnson subsp. ''watsoniana'' has late juvenile and intermediate leaves with the leaf blade tapering to the petiole.
