The Convention on Biological Diversity (CBD) adopted a consolidated update (X/17 https://www.cbd.int/decision/cop/?id=12283) of the Global Strategy for Plant Conservation (GSPC) for the decade 2011–2020 at its 10^th Conference of the Parties held in Nagoya, Japan in October 2010. The updated GSPC includes five objectives and 16 targets to be achieved by 2020. Target 1 ambitiously aims to complete “an online flora of all known plants” by 2020. A widely accessible flora of all known plant species is a fundamental requirement for plant conservation and provides a baseline for the achievement and monitoring of other targets of the Strategy. The previous (GSPC 2010) target 1 aimed to develop “a widely accessible working list of known plant species as a step towards a complete world flora,” and this target was achieved at the end of 2010, as The Plant List (http://www.theplantlist.org). Drawing from the knowledge gained in producing The Plant List, a project to create an online world flora of all known plant species is now underway. A World Flora Online (WFO) Council has been formed with twenty-nine participating institutions worldwide and supporting Technical and Taxonomic Working Groups, who are diligently working to achieve the 2020 target. The WFO Council and Working Groups last met in January 2015 in Geneva, Switzerland. An information portal is online at http://www.worldfloraonline.org. A public portal is now in development built upon the e-Monocot.com software platform developed by Oxford, Kew and the Natural History Museum. A demonstration portal containing sample data is planned to be available in October 2015. The demonstration portal will accommodate regional floristic information (at national or lower level), synonymy, images, descriptions, country-level distribution, conservation status, and vernacular names. Future enhancements are planned to include alternate taxonomic hierarchies and synonymy with sources; habit and habitat data; identification tools, principally interactive keys; phylogeny; and other enhancements as practicable. This presentation will describe the vision, progress to date and plans for this new and significant global project.
