In delivering the World Checklist of Vascular Plants (WCVP), we acknowledge the contribution of the many people and institutions who collaborate with us.
WCVP is built on the nomenclatural data provided by the International Plant Names Index (IPNI) which is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium, combined with the taxonomic data provided by the World Checklist of Selected Plant Families (WCSP) which is an international collaborative programme with a large number of contributors from around the world. We would also like to thank all the reviewers who peer reviewed the families made available through the WCSP website. Our thanks also go to the compilers and editors of IPNI and WCSP and in particular the thousands of users who have contributed corrections over the past decades, improving those data for the global user community.
Our particular thanks go to the people and institutions who have provided us with name and taxonomic data over the years. In particular Missouri Botanic Garden, The New York Botanic Garden, iPlants, The Catalogue of Life Partnership, Solanaceae Source, Mohammad El-Labban (Lebanon & Syria data), Ori Fragman-Sapir & Avinoam Danin (Flora of Israel Online), Richard Pankhurst, Royal Botanic Gardens, Edinburgh (Rosaceae) and the Species Plantarum Programme.
