Dear colleagues,

We are delighted and deeply honored to announce that the next International Botanical Congress ―the 20th IBC— will take place in Madrid (Spain) on the following dates:

• Nomenclature Section, 15–19 July 2024
• Congress, 21–27 July 2024

The IBC takes place every six years under the supervision of the International Association for Botanical and Mycological Societies (IABMS). The 20th was scheduled to take place in 2023 in Brazil after Shenzhen’s (China) 2017. Unfortunately, the difficult situation caused by the worldwide pandemic has made impossible to organize this big event in Brazil in 2023.

Rooted in the tradition of Systematic Botany, the IBCs have enlarged their scope over more than a century to become an integrated forum for knowledge on the plant and mycological world. Please take a look at the broad scope of topics that we hope to include in this upcoming IBC in this site.

The Congress will include plenary lectures, concurrent symposia ―for which we will ask for proposals in Spring 2022—, posters, exhibitors, as well as short courses and workshops.

We wholeheartedly invite all the botanical community worldwide to come to participate in the 20th IBC and enjoy, in Madrid, the privilege of sharing research, knowledge and experiences with colleagues and friends from all over the planet. We will make efforts to provide the best environment for such a thrilling experience.

A suite of post-meeting excursions will be offered for attendees to visit places of botanical and cultural interest. See the preliminary list in this site.

We look forward to seeing you all in Madrid in July 2024.

Kind regards,
The Organizing Committee of the 20th IBC
