Department of Botany staff members and affiliates joined colleagues from near and far at the XX International Botanical Congress (IBC) in Madrid, Spain, from July 21-27, 2024.
Immediately preceding the main program of the XX IBC, the Nomenclature Section of the Congress took place at the central campus of the Consejo Superior de Investigaciones Científicas (CSIC) in Madrid from July 15-19. This Section was presented by the Congress’s Bureau of Nomenclature as prescribed by the International Code of Nomenclature for algae, fungi, and plants (ICN). Sandra Knapp (Natural History Museum, London), president of the Bureau of Nomenclature, chaired the session, with expertise and guidance given by the Rapporteur-général, Nicholas Turland (Botanischer Garten und Botanisches Museum Berlin), and the Vice-rapporteur, John Wiersema (Smithsonian Research Associate). The Nomenclature Section deliberated 433 proposals to amend the ICN. Others attending from the Botany Department were Laurence Dorr, Rose Gulledge, Paul Peterson, Eric Schuettpelz, Robert Soreng, Kenneth Wurdack, and Smithsonian Research Associate Morgan Gostel. Important topics that were discussed included proposals on culturally sensitive issues as well as the removal of a significant set of names based on racially offensive terms, and a clear mechanism for the voluntary registration of names and types of algae and plants.
The Congress opened on 21 July with registration and a reception at the IFEMA (Institución Ferial de Madrid) convention center, attended by thousands of participants. The program officially began with an opening talk by Knapp followed by a traditional Spanish dance performance. The Congress focused on the newest developments in the botanical sciences worldwide and included plenary talks, general lectures, symposia, poster sessions, and workshops. All aspects of basic and applied botanical research were included. More than 3,000 participants attended from all around the globe, making the XX IBC a truly international event.

Departmental members and research associates who attended and presented talks, posters, and workshops during the scientific sessions were Marc Appelhans, Alberto Coello, Laurence Dorr, Morgan Gostel, Rose Gulledge, Amanda Grusz, Richie Hodel, Gary Krupnick, Paul Peterson, Vijay Raman, Eric Schuettpelz, Robert Soreng, Alicia Talavera, Jun Wen, and Kenneth Wurdack. Co-authors of talks and posters who could not attend the meeting were Pedro Acevedo, Gabriel Johnson, John Kress, Sylvia Orli, Kostya Romaschenko, Luke Sparreo, Gregory Stull, and Elizabeth Zimmer.
Small group meetings and workshops were organized by members and affiliates of the Department, including the International Compositae Alliance (TICA; Morgan Gostel) and the International Association of Plant Taxonomy (IAPT) business meeting (Laurence Dorr, Sally Eichorn, Warren Wagner, and Morgan Gostel).
