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. (en)
