The template (shortcut ) is for properly formatting the name of a graft chimera in the context of a scientific name (or as one), to comply with the International Code of Nomenclature for Cultivated Plants (ICNCP). The style it uses has also been adopted by the British Royal Horticultural Society (RHS) and many other organizations, and is standard practice in all horticultural writing (though exact spacing particulars may vary from publisher to publisher).{{Graft chimera}}{{Chimera}}
This template should not be substituted. It is not designed for that, and doing so will impede part of the purpose of the template (to mark up chimerae names in a predictable, automated way so that if ICNCP changes their prescribed nomenclatural markup, a simple change to this template will apply the new style site-wide).
Usage in a book title in running prose (not in citation templates): For things italicized in running text (like a chimera name), the convention is to invert the italics when these appear inside a book title or other surrounding string that is itself italicized. This can be done with this template by using |invert=yes (or |invert=y). Example:
This must not be used in titles of works in citation templates, as such markup breaks the citation template's COinS metadata. Just use a manual + ''Crataegomespilus'' (without {{nowrap}} or other templating).
