Organisms long known as “blue-green algae” or “cyanophytes”, and more recently as “cyanobacteria”, are currently governed by both the rules of the International Code of Nomenclature for algae, plants, and fungi (ICN) and the International Code of Nomenclature of Prokaryotes (ICNP) and a reciprocal principle of code coordination is agreed so that names validated in either codes are treated as valid in the other code. Under the ICN, both descriptive and typified names above the level of family are permitted, and the principle of priority does not apply. The current names in use, along with the typified or descriptive phyla/division, and class names applied to cyanophytes, are discussed, and recommendations for their use are provided.
