Welcome to Plants of the World Online (POWO) which is an international collaborative programme that has as a primary aim to make available digitized data of the world’s flora gathered from the past 250 years of botanical exploration and research. POWO also aims to make freely available electronic data created by different projects but that no longer have an online presence or where data was never made available externally. It delivers information on the taxonomy, identification, images, distribution, traits, threat status, molecular phylogenies and uses of vascular plants worldwide. The data are sourced from the Royal Botanic Gardens, Kew as well as its partners and collaborators who generously contribute data and make it openly accessible on POWO.
Launched in March 2017 by the Royal Botanic Gardens, Kew, with an initial focus on tropical African Floras was made possible through the generous support of our benefactors, Michel and Hélène David-Weill. POWO’s aim is to empower and inform citizens, policy makers, conservationists, horticulturalists, farmers, gardeners and plant enthusiasts globally. The codebase is open source and Kew supports existing partner networks to set up their own portals, creating a distributed network of botanical data hubs.
