International Code of Botanical Nomenclature

(Tokyo Code), Electronic version


Article 54

54.1. Consideration of homonymy does not extend to the names of taxa not treated as plants, except as stated below:

(a) Later homonyms of the names of taxa once treated as plants are illegiti-mate, even though the taxa have been reassigned to a different group of organisms to which this Code does not apply.

(b) A name originally published for a taxon other than a plant, even if validly published under Art. 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 of this Code, is illegitimate if it becomes a homonym of a plant name when the taxon to which it applies is first treated as a plant (see also Art. 45.5).

Note 1. The International code of nomenclature of bacteria provides that a bacterial name is illegitimate if it is a later homonym of a name of a taxon of bacteria, fungi, algae, protozoa, or viruses.
