Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...
