The Legume Phylogeny Working Group (LPWG) is dedicated to advancing research and understanding of the Leguminosae family, one of the largest and most diverse in the plant kingdom. With nearly 800 genera and over 23,000 species, legumes are integral to global ecosystems and human livelihoods. They provide essential sources of protein and micronutrients, making them key food crops worldwide.

Beyond their nutritional benefits, legumes serve various ecological functions, including nitrogen fixation, which enhances soil health. This family includes a myriad of plant forms, from large tropical trees to small herbs, and exists in nearly every biome. The LPWG facilitates collaborative studies in legume systematics and evolution, producing vital classifications and research papers that shape scientific understanding of these plants.

Their initiatives include working groups that focus on taxonomy, phylogenomics, and trait data, encouraging community participation to enhance collective knowledge. The portal serves as a comprehensive resource for researchers and enthusiasts alike, promoting the significance of legumes in ecological and agricultural contexts
