The species is part of the ''Eucalyptus'' subgenus series ''Diversiformae'', a group of mallees that all have adult leaves held erect, buds with a single unscarred operculum and pyramidal seeds. The other species in this series include ''
E. erectifolia'', ''
E. platydisca'', ''
E.diversifolia'', ''
E. todtiana'', ''
E. lateritica'', ''
E. dolorosa'' and ''
E. pachyloma''.
Distribution
Apple mallee is found on coastal and near-coastal sandplains and ridge tops along the south coast in the
Great Southern region of Western Australia between
Albany in the west,
Mount Barker in the north and
Jerramungup in the east where it grows in gravelly sandy-clay soils.
