International Association for Plant Taxonomy

The International Association for Plant Taxonomy (IAPT) is an organization established to promote an understanding of plant biodiversity, facilitate international communication of research between botanists, and oversee 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. The IAPT headquarters is located in Bratislava, Slovakia. Its president, since 2017, is Patrick S. Herendeen of the Chicago Botanic Garden; vice-president is Gonzalo Nieto Feliner of the Real Jardín Botánico, Madrid; and secretary-general is Karol Marhold of the Plant Science and Biodiversity Centre, 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, Index Nominum Genericorum, and Index Herbariorum.
