The legume systematics communitys long history of research and collaboration has greatly increased our understanding of the classification, biogeography and evolutionary history of the family. This is evident in the many activities and publications that have seen the light since 1978, when the first International Legume Conference was held at the Royal Botanic Gardens, Kew. In 2010, the Legume Phylogeny Working Group (LPWG) was founded, and has since published five papers under this name, including a new phylogeny-based subfamily classification and a revised higher-level classification for subfamily Caesalpinioideae. In 2020 the LPWG established five working groups to promote collaboration on specific aspects of legumes. The Taxonomy Working Group was created to work on a list of names that would feed into and support the underlay of the other four working groups. This has led to the publication of four versions of updated legume taxon names from which out of the 64 351 specific names ever published in the family we now accept 22 623 species and 797 genera. The Legume Taxonomy Working Group is now acknowledged as an active legume partner and contributor to the international World Flora Online project and Global Biodiversity Information Facility (GBIF) and serves as the authoritative source for legume names in both portals. A collaborative online platform, Rhakhis, was chosen for the community to continue updating names. Working with GBIF, the legume community developed a portal focused on the family, and this led to the launch of the first version of GBIFs phylogeny viewer based on a phylogenomic analysis of Caesalpinioideae. Other international collaborations to pursue phylogenomic analyses and data sharing, including morphological and geographical data, have been encouraged to facilitate monographic, phylogenetic, macro-evolutionary and biogeographical analyses of this ecologically important family.
