World Checklist of Useful Plant Species

Plants are essential to human wellbeing, supporting important ecosystem services that are critical components of Natural Capital. They supply food, medicine, fibre, fuel and building materials, and provide a broad spectrum of benefits to society, offering vital solutions to some of the world’s major challenges, including bioenergy, human and animal health, nutrition, microbial resistance, industrial biotechnology, and synthetic biology. In 2016, the Royal Botanic Gardens, Kew published the first State of the World's Plants report, with key statistics on plants. One of its highlights was the compilation of a list of 31,128 plant species with a documented human use from ten datasets (Diazgranados et al. 2018; RBG Kew 2016). Here, we added the datasets from the Medicinal Plant Names Services (MPNS version 8.2), the Plant Resources of South-East Asia (PROSEA) and the Useful Plants of New Guinea, for a total of 13 large datasets. The resulting checklist contains 40,292 species, including nine non-plant taxa retained because they are frequently misidentified as plants (e.g. nostoc, forkweed, brown algae). The checklist is classified into three kingdoms (Plantae with 40,283 species, Chromista with eight species, and Bacteria with one species), six divisions/phyla, 14 classes, 101 orders, 433 families and 6,737 genera.
