From a species to a genus: This is a redirect from a taxon's full binomial name (genus & species) to the taxon's higher level genus. Note that the practice of creating redirects from species names that could be articles is strongly discouraged.
Use {{R taxon with possibilities}} for redirects that could potentially be expanded into their own articles.
To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}}instead.
To a list entry: This is a redirect to a list in which the subject is an entry.
For redirects from a topic to a related list and not to an entry on that list, use {{R from list topic}}instead.
