Editing Eucalypt (section)

== Taxonomy ==
For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''.{{cn|date=October 2023}}

Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group.<ref name= 2003MyrtaceaeBiogeogr/><ref name=Lyne1996/><ref name= 2002StockwelliaNewGenus/><ref name=Costermans2006TreesVic/>

The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six known species, restricted to monsoon forests and rainforests in north-eastern Australia, the [[Arnhem Land]] plateau, [[New Guinea]], the [[Moluccas]] and [[New Caledonia]]. These genera are recognised as having evolved from ancient lineages of the family Myrtaceae. According to genetic, fossil and morphological evidence, it is hypothesised that they evolved into separate taxa before the evolution of the more widespread and well-known genera ''Eucalyptus'', ''Corymbia'' and ''Angophora'', and all of their many species.<ref name= 2003MyrtaceaeBiogeogr/>

''[[Eucalyptus deglupta]]'' has naturally spread the furthest from the Australian geographic origin of the genus ''Eucalyptus'', being the only species known growing naturally in the nearby northern hemisphere, from [[New Guinea]] to [[New Britain]], [[Sulawesi]], [[Seram Island]] to [[Mindanao]], [[Philippines]].<ref name= 2003MyrtaceaeBiogeogr/> ''[[Eucalyptus urophylla]]'' also grows naturally as far west as the [[Flores]] and [[Timor]] islands.<ref name= 2003MyrtaceaeBiogeogr/>
