[1] The International Code of Nomenclature for algae, fungi, and plants (ICNafp) provides the following options in dealing with a hybrid:[2] A hybrid name is treated like other botanical names, for most purposes, but differs in that:[2] Hybrids can be named with ranks, like other organisms covered by the ICNafp.
Nothotaxon names with the rank of a subdivision of a genus (notho-subgenus, notho-section, notho-series, etc.)
are also published by listing the parent taxa and without descriptions or types.
Hybrids involving four or more genera are formed from the name of a person, with suffix -ara, e.g., × Belleara.
