- From a monotypic taxon: This is a redirect from a monotypic plant taxon to its only lower-ranking member. In a biology-related article, when for example a family has only one genus, the family may be a redirect to the genus.
- Use {{R to monotypic taxon}} when making a redirect to a monotypic taxon from its only member, for example, from a species to the genus of which it is the only member.
- With history: This is a redirect from a page containing substantive page history. This page is kept as a redirect to preserve its former content and attributions. Please do not remove the tag that generates this text (unless the need to recreate content on this page has been demonstrated), nor delete this page.
- This template should not be used for redirects having some edit history but no meaningful content in their previous versions, nor for redirects created as a result of a page merge (use {{R from merge}} instead), nor for redirects from a title that forms a historic part of Wikipedia (use {{R with old history}} instead).
