Template:Is reg/doc

Usage

Input: |1=Taxon name

Output:

• If Taxon is a regnum (or equivalent higher category),

  [[{{{1}}}]]

• Else: Null.

Intended use: Call repeatedly for each taxon in a taxobox (using {{Get regnum()}}). Because a null string is returned for all non-regna, all that remains will be the regnum. Pass this output to {{Taxobox colour}} to generate colours for a taxobox.

Examples

• {{is reg|Animalia}} → animalia
• {{is reg|Columbidae}} →
