The World Flora Online will be an open-access, Web-based compendium of the worlds plant species. It will be a collaborative, international project, building upon existing knowledge and published floras, checklists and revisions but will also require the collection and generation of new information on poorly know plant groups and plants in unexplored regions. WFO replaces The Plant List

The World Checklist of Vascular Plants aims to deliver a sustainable and curated resource. It is based on Kew’s names and taxonomic backbone which has been created by reconciling the names from the International Plant Names Index (IPNI) with the taxonomy from the World Checklist of Selected Plant Families (WCSP). This Beta version therefore only displays names that are in both IPNI and WCVP. It contains both families that have been completed and peer reviewed by both external and internal experts on the relevant families as well as families that are in the process of being edited and reviewed. Some of the original data which WCSP built upon came from our generous collaborators listed in the acknowledgements. WCVP aims to represent a global consensus view of current plant taxonomy by reflecting the latest published taxonomies while incorporating the opinions of taxonomists based around the world
