Numbers
The statistics refer to the public database after the last refresh (2021-09-16). Note that the internal database can be significantly larger at a given time point because as yet not all entries underwent the final quality check. More information on type-strain deposits in Biological Resource Centres (BRCs) is found on the culture collection page. Information on the International Code of Nomenclature of Prokaryotes (ICNP) is provided on the nomenclature page. Validly published names of Cyanobacteria are mostly validly published under International Code of Nomenclature for algae, fungi, and plants (ICN).
For the approximate number of taxonomic proposals per country see the page on corresponding authors. For the number of species per genus, see the page on the largest genera. There is also a page on the number of taxon names per year.
