The 8th International Legume Conference (8ILC, www.8ilc.com) took place from 6th to 11th August 2023 in Pirenópolis, Brazil, one of the most charming towns in the heart of the savanna landscapes of the Cerrado biodiversity hotspot. The ILC is a series of international conferences focused on the legume family. It encompasses a wide range of topics, including but not limited to systematics, evolution, biogeography, morphology, ecology, biological nitrogen fixation, and genomics. Although this event was inaugurated in 1978, it does not adhere to a set periodic schedule; in recent years, however, it has been convened approximately every five years. For the first time, the ILC was held in Brazil, a country renowned for its extraordinary biological and cultural diversity, and home to a vibrant community of legume researchers. The International Association for Plant Taxonomy (IAPT), reaffirming its commitment to fostering global taxonomy and systematics, was among the 8ILC sponsors.

Since its inception, the ILC has firmly established itself as a prominent international meeting, attracting a diverse and extensive participation of researchers from various countries and continents, as well as a remarkable presence of students. By fostering global collaboration among researchers, well exemplified by the formation of the Legume Phylogeny Working Group (LPWG), the ILC is a welcoming environment in which new scientifically exciting ideas and advances in the legume family arise. For example, the 6ILC in 2013 in Johannesburg, South Africa, set the stage for establishing the new phylogeny-based subfamily-level classification of the Leguminosae. The extensive discussions on the new legume classification that emerged during the 6ILC were the basis for the publication of two papers in Taxon in 2013 and 2017, under the auspices of the LPWG: (1) a review paper discussing the progress made to date in the molecular systematics and the need for a revised classification of the family (LPWG, 2013: https://doi.org/10.12705/622.8), and (2) the new subfamily-level classification (LPWG, 2017: https://doi.org/10.12705/661.3). Since its publication in early 2017, the LPWG's new classification of legumes at the subfamily level has become successful not only in the legume community. Its impact across plant science is demonstrated by the fact that it has already reached the landmark of becoming the second-most cited paper ever published in Taxon.

The 8ILC in Pirenópolis was centered around the theme of “Integrating Knowledge on the Legume Family”. At the Opening Ceremony on 6th August, Marcelo Simon (Chairperson of the 8ILC) addressed the conference by welcoming all delegates. Then, Professor Fabio Scarano (Universidade Federal do Rio de Janeiro) delivered the opening keynote talk “Legumes and futures: Dialogues between different ways of knowing”.

The global legume community was well represented, with 147 participants hailing from 18 countries,

On 2 December 2023, at the annual celebration of the foundation of the Royal Physiographic Society of Lund, Sweden, the Rolf and Gertrud Dahlgren Prize for 2023 was awarded to Louis Ronse De Craene, Royal Botanic Garden, Edinburgh. The Prize, inaugurated in 1988, is given every third year to a scientist who has made major contributions to botany in the broad-minded spirit of Rolf and Gertrud Dahlgren, particularly in the fields of systematics and evolution of the angiosperms, and regardless of their nationality. The prize-winner is chosen by active researchers in various fields of botany. Ronse De Craene has been awarded the prize for his work on floral development in a broad range of angiosperm families and the importance of floral morphology in the context of modern phylogenetic studies.

Ronse De Craene was born in Kortrijk/Courtrai (Flemish Region of Belgium) in 1962. He obtained an M.Sc. at the University of Reading (U.K.) in 1986, with a thesis in which he proposed a clearer circumscription of the genus Polygonum based on floral morphological and anatomical characters. He received a doctorate at the Catholic University of Leuven (Belgium) in 1992 on a dissertation about the androecium of the angiosperms (The androecium of the Magnoliophytina: Characterisation and systematic importance). After postdoctoral research at Leuven for eight years, he became Director of the M.Sc. program in Biodiversity and Taxonomy of Plants jointly organised by the Royal Botanic Garden Edinburgh (RBGE) and the University of Edinburgh, a post he held from 2002 to 2022. He remains attached at the RBGE as a Research Associate and an external lecturer.

At Leuven and Edinburgh, Ronse De Craene developed a broad research program on flower morphology, studying in detail the floral development and anatomy of many angiosperm families in collaboration with scientists around the world. His most important contribution is a book entitled Floral diagrams: An aid to understand floral morphology and evolution, published by Cambridge University Press in 2010 (revised second edition in 2022). This book explores floral morphology of the angiosperms as an essential counterpart of their molecular phylogeny, and it continues in modern botany the scientific approach of Carolus Linnaeus, Wilhelm Eichler, Eugen Warming, and Rolf Dahlgren, among others. Taken as a whole, Ronse De Craene's work represents a valuable combination of research in several areas of systematics and evolution of the angiosperms.

The Rolf and Gertrud Dahlgren Prize is awarded by the Royal Physiographic Society at Lund, an institution with the secondary title of Academy for the Natural Sciences, Medicine and Technology. This academy was founded on 2 December 1772, by, among others, the botanist Anders Jahan Retzius, for whom the South African genus Retzia (Retziaceae, or Stilbaceae) is named, and father of the anatomist Anders Adolf Retzius. Carl Peter Thunberg was
