Usage
Input: |1=Taxon name
Output:
- regnum (or equivalent higher category), linked
Calls Template:Is reg repeatedly for each taxon in a taxobox. Because that template returns a null string for all non-regna, all that remains will be the regnum. Pass this output to {{Taxobox colour}} to generate colours for a taxobox.
Examples
{{get regnum|Columbidae}}→ animalia
