You are presupposing that Asparagaceae (or perhaps "Asparagaceae") is defined under the ICN. The code, however, claims merely to regulate nomenclature, providing definitions only of words like "cultivar" (in Appendix VII), words that do not name taxa. Even if you can produce a reliable source for your claim that names are defined in terms of a type and a rank (a claim that is also made in the lead), you have a problem with neutrality; Monsch (2003), for example, argues that names do not have definitions. The ICN entries, on this view, only fix the reference of names, while a definition—if one were possible—would provide the meaning. The meaning/reference distinction is much discussed in recent philosophy.   16:23, 24
