The nomenclature of Cyanophyta under the Botanical Code

Compère, Pierre


For a long time, blue-green algae were considered as true algae and their nomenclature was ruled only by the International Code of Botanical Nomenclature (ICBN); in the current edition of this code (Greuter et al. 2000), Preamble 7 cites namely blue-green algae (Cyanobacteria) among the “organisms traditionally treated as plants” to which rules and recommendations (of this code) apply. Thus even after the recognition of the prokariotic character of the blue-green algae, their nomenclature may continue to be governed by the ICBN. Therefore most of the scientific names now applied to Cyanobacteria/Cyanophyta have been published under the Botanical Code and their validity or their correctness remain submitted to this Code. In this presentation of the Botanical Code, the rules and principles will be shortly commented with a stress on the conditions of valid publication of new names, the conditions of validity for already published names and the provisions of the Code concerning specifically the blue-green algae.
