      Abstract

      Abstract The Global Strategy for Plant Conservation of the Convention on Biological Diversity adopted as its first target in 2010 the preparation of "An online flora of all known plants " by 2020. This target was subsequently adopted by a broadly-based international consortium of botanical institutions that have committed themselves to undertaking this ambitious project. The preparation of a world flora will be the first modern and large-scale and comprehensive attempt to produce a comprehensive overview and baseline of knowledge on the world's plant diversity. This article outlines previous historic efforts to document the world's known flora. It also describes the ways in which the World Flora Online Consortium was created, how it is organized and its plans to compile diverse datasets available in digital formats into a single online portal available and open to all. Such data are being combined from geographical floristic accounts, such as the Flora of China, the Flora of North America and many other regional and national projects, together with relevant monographic treatments.

      Resumo A Estratégia Global para a Conservação das Plantas e a Convenção da Biodiversidade adotaram em 2010, como a primeira meta para 2020, a produção de uma flora online de todas as espécies conhecidas . Tal meta foi assumida por um amplo grupo de participantes provenientes de diversos institutos botânicos e esta comunidade comprometeu-se a atingir essa meta. O primeiro Consórcio da Flora On-line foi criado com a finalidade de preparação de uma flora mundial moderna e em larga-escala, provisionando a primeira tentativa de produzir uma estrutura para embasar a totalidade do conhecimento botânico mundial. O presente artigo expõe esforços históricos prévios realizados para documentar a flora do mundo, assim como a presente organização do Consórcio da Flora On- line, cujo objetivo é compilar diversas bases de dados disponíveis em formatos digitais distintos num portal de acesso aberto ao público. Os dados estão sendo combinados a partir de tratamentos regionais distintos, como a Flora da China, Flora da América do Norte e muitos outros projetos regionais e nacionais, combinados a monografias relevantes.

      How many species of flowering plants are there?

      We estimate the probable number of flowering plants. First, we apply a model that explicitly incorporates taxonomic effort over time to estimate the number of as-yet-unknown species. Second, we ask taxonomic experts their opinions on how many species are likely to be missing, on a family-by-family basis. The results are broadly comparable. We show that the current number of species should grow by between 10 and 20 per cent. There are, however, interesting discrepancies between expert and model estimates for some families, suggesting that our model does not always completely capture patterns of taxonomic activity. The as-yet-unknown species are probably similar to those taxonomists have described recently—overwhelmingly rare and local, and disproportionately in biodiversity hotspots, where there are high levels of habitat destruction.
