Acacia mutabilis subsp. Young River (G.F. Craig 2052) is more recently known as Acacia mutabilis Maslin subsp. mutabilis.

Reason In a recently conducted review of Acacia mutabilis it became obvious that there are many specimens included in A. mutabilis subsp. mutabilis that are the same entity as A. mutabilis subsp. Young River (G.F. Craig 2052). There exists very complex patterns of variation within A. mutabilis subsp. mutabilis and it is not possible to resolve in the near term. Therefore, the only practical solution at present is to incorporate the A. mutabilis subsp. Young River (G.F. Craig 2052) specimens into A. mutabilis subsp. mutabilis. B.R. Maslin, 18 Aug 2025.

What do the terms mean?

Backward Reference
References that link from new to old (e.g. back to the previous name), or from child to parent (e.g. back up the taxonomic hierarchy).
Concept change
A taxon has been redefined by a newer publication, keeping the same name.
Current
The name is accepted for use in the Western Australian Flora.
Excluded name
A name has been referred to in literature but is not present in Western Australia. This is a special case of a misapplied name. One reference will be present for each exclusion.
Formally Described
A name previously referred to informally with a manuscript or phrase name has subsequently been formally described.
Forward Reference
References that link from old to new (e.g. forward to the new name), or from parent to child (e.g. down the taxonomic hierarchy).
Misapplied name
A name has been used in literature that refers to one or more different taxa. One reference will be present for each taxon this name is misapplied against.
Nomenclatural synonym
A taxon has changed its relationship to other taxa but the circumscription is the same. This is the case in a generic revision, where only the generic epithet (and perhaps the suffix used on the specific epithet) changed. One reference will be present for each taxon this name is nomenclaturally synonymous with.
Not Current (or Non-current)
The name is not an accepted name for use in the Western Australian Flora
Taxonomic synonym
A name is recognised to be referring to the same taxon as an earlier published name. One reference will be present for each taxon this name is taxonomically synonymous with.
