The Legume Taxonomy Working Group has the central goal of putting together a community-endorsed consensus list of legume species names and their synonyms. Because several online sources are now out of date, the legume community considered this initiative critical to underpin ongoing and future legume research. The group was established in May 2020 and its aim is to provide an accurate and up-to-date family classification that can be used for down-stream analyses of all kinds of applied and fundamental research questions, including conservation, agronomic and green infrastructure purposes. This up-to-date species list will also provide the critical backbone for other LPWG working groups focusing on assembling occurrence and functional trait data from public databases, literature and collections, for example. Ultimately, we would expect the LPWG-verified and endorsed species list to be adopted and used as the taxonomic backbone for Leguminosae for large international initiatives such as the Global Biodiversity Information Facility (GBIF), Catalogue of Life, World Flora Online, and several ongoing phylogenomic projects. This is important to avoid duplication of efforts by a small pool of taxonomic experts.
In collaboration with Rafaël Govaerts at Royal Botanic Gardens, Kew, the Taxonomy Working Group initiated the process using Kew’s core checklist data, available for download on Kew’s World Checklist of Vascular Plants (WCVP). This core checklist links to the International Plant Name Index (IPNI) and also underlies the Plants of the World Online website. The WCVP list includes all the Darwin Core fields that the legume community considers important for downstream analyses. To revise the list of legume species names, a network of 38 coordinators for the subfamilies (and tribes for Papilionoideae) were assigned the task of approaching other legume taxonomic experts for assistance in checking and editing the list of legume names. The revised lists are forwarded to Rafaël Govaerts who checks the proposed modifications and integrates the information in an updated legume species list. The Taxonomy Working Group has also established an arbitration committee whose role is to evaluate and arrive at a decision about conflicting taxonomies (often, whether or not to recognise certain genera), and which met for the first time in December 2020. The revised species list will acknowledge the input of contributors to the ratification of the legume taxonomy. The plan is to have a list of accepted names in draft format during the first half of 2021.
Down the line, the taxonomic list will be used to link to and synthesise other data types – traits, descriptions, higher level taxonomy, occurrence and specimen data, dynamic maps and images. One of the goals of the LPWG is to collate information on legumes so that it is easily accessible and useful to researchers and other users around the world. For this, the legume community is developing an online portal for the family which can encompass richer data sets from multiple partners using a sound species checklist and benefiting from knowledge held in “Legumes of the World Online”. The current collaboration represents an important step toward achieving that goal.

The LPWG recently applied for a pilot portal via a new program at GBIF. This application was successful and the LPWG community, in coordination with the Canadensys GBIF node, will implement a thematic portal in the first half of 2021. This pilot will serve all legume occurrences currently in GBIF and will be underpinned by the consensus list of legume names and will also allow easy viewing of the legume taxonomy used. The portal will also have areas for describing the work of the four LPWG working groups. The portal is not expected to meet all LPWG needs, but will provide a first step for showcasing the work of the LPWG and more broadly the family Leguminosae.
