Welcome to the website of the
International Society for Phylogenetic Nomenclature.

The ISPN encourages the development and use of phylogenetic nomenclature and oversees the implementation of a code of rules to govern phylogenetic nomenclature — the PhyloCode.

The society is open to anyone wishing to partake in this venture.
