The International Association for Plant Taxonomy (IAPT) promotes an understanding of plant biodiversity, facilitates international communication of research between botanists, and oversees matters of uniformity and stability in plant names. The IAPT was founded on July 18, 1950 at the Seventh International Botanical Congress in Stockholm, Sweden.[1] Currently, the IAPT headquarters is located in Bratislava, Slovakia. Its current president, since 2011, is Vicki Funk of the Smithsonian Institution, Washington, DC.; vice-president is Sandra Knapp of the Natural History Museum, London; and secretary-general is Karol Marhold of the Institute of Botany, Slovak Academy of Sciences, Bratislava.

Both the taxonomic journal Taxon and the series Regnum Vegetabile are published by the IAPT. The latter series includes the International Code of Nomenclature for algae, fungi, and plants, the Index Nominum Genericorum, and Index Herbariorum.

The IAPT's primary purpose is the promotion and understanding of biodiversity—the discovery, naming, taxonomy, and nomenclature. This is accomplished in part through sponsorship of meetings and publication of resources, such as reference publications and journals.

The IAPT also seeks to achieve uniformity and stability in plant names. It accomplishes this through the International Code of Nomenclature for algae, fungi, and plants, previously known as the International Code of Botanical Nomenclature, and through the oversight of the International Bureau for Plant Taxonomy and Nomenclature.

Publications and online resources


Taxon[3] is the bi-monthly journal of the IAPT. The journal, which was initiated in 1951, publishes original papers and reviews dealing with systematic botany in the broadest sense. Preference is given to integrative papers combining the results of modern analysis with their consequences for classification. Taxon also contains matters related to [5] it has been in the past criticized for focusing overly on nomenclature and less on the principles and advancements made in the field of plant systematics.[6]

Regnum Vegetabile

Regnum Vegetabile[7] is a published series of books on topics of interest to plant taxonomists. Many of the volumes are literature surveys or monographs in the area of plant systematics. There are several volumes of general use:

  • International Code of Nomenclature for algae, fungi, and plants (Vol. 154, 2012) The ICN is a set of rules and recommendations dealing with the formal names that are given to plants. The current edition is known as the "Melbourne Code", as it was drafted in 2011 at the Seventeenth International Botanical Congress in Melbourne, Australia.
  • International Code of Nomenclature for Cultivated Plants, 8th edition (Vol. 151, 2010) Companion to the ICN, this volume sets forth rules regarding the names of plant cultivars.
  • Index Nominum Genericorum (Vols. 100-102 & 113) An index of all published generic names covered by the ICN, including the place of publication and information about the type species. The index is prepared in collaboration with the Smithsonian Institution. An electronic version is available online.
  • Index Herbariorum, the first six editions (Vol. 15, 31, 86, 92, 93, 106, 109, 114, 117, 120) A directory and guide to the herbaria of the world, including contact information, abbreviation codes, and important collections located in each herbarium. Index Herbariorum is now an online database, managed by The New York Botanical Garden, and available for on-line searching.
  • International Directory of Botanical Gardens (Updated as Vol. 95, 1977) A directory to botanical gardens and arboreta around the world.

The series includes many additional volumes of interest to specialists in specific subdisciplines of botany, in addition to the ones listed above.


In addition to electronic versions of its print publications, the IAPT maintains the following:

  • "Names in Current Use"[8] - A database of scientific names of extant botanical genera.
