`  == Your edits to Template:Automatic taxobox ==  As part of this set of edits, you changed: :| parent = {{Taxobox/taxon|{{{taxon|}}}|{{{1|}}} }} to the following, if I strip out the insertion of ``Acacia``: :| parent = {{Taxobox/taxon|{{{taxon|{{PAGENAME}}|}}}|{{{1|}}} }} However, these don't have the same behaviour. Since the first parameter to  now always has a value, your code is equivalent to: :| parent = {{{taxon|{{PAGENAME}} }}} so (a) the invocation of  is redundant (b) the anonymous first parameter to  can't be used, so {{Automatic taxobox|Acer}} doesn't work, whereas it used to. I think you should either restore the original behaviour, or, since I don't believe that the form with an unnamed parameter is ever used (or desirable), remove the redundant use of .   `
