About the ISPN

The International Society for Phylogenetic Nomenclature was established to encourage and facilitate the development and use of, and communication about, phylogenetic nomenclature. Toward this end, the ISPN organizes periodic scientific meetings and oversees the implementation of a code of rules to govern phylogenetic nomenclature—the PhyloCode. PhyloCode names can be viewed and submitted via the registration database, RegNum.

The ISPN is governed by a Council, of which all members except the Program Director are elected. For more information, see the Bylaws (PDF).

The ISPN maintains two committees whose responsibilities pertain directly to the functioning of the PhyloCode: the Committee on Phylogenetic Nomenclature (CPN) and the Registration Committee. The members of both committees are elected by the ISPN membership.

The CPN is responsible for reviewing and approving changes to the PhyloCode. The CPN also rules on proposals for conservation or suppression of names, resolves ambiguities in the provisions of the code, amends the provisions of the code, and will produce future editions of it.

The Registration Committee is responsible for managing the online registration database for names governed by the PhyloCode.

Anyone who is interested in phylogenetic nomenclature is encouraged to join the ISPN.

The Society welcomes donations!
