The World Flora Online (WFO) is an open-access database, launched in October 2012 as a follow-up project to The Plant List, with the aim of publishing an online flora of all known plants by 2020. [1] It is a project of the United Nations Convention on Biological Diversity, with goal of halting the loss of plant species worldwide by 2020.
The diversity of flowering plants is not evenly distributed. Nearly all species belong to the eudicot (75%), monocot (23%), and magnoliid (2%) clades. The remaining five clades contain a little over 250 species in total; i.e. less than 0.1% of flowering plant diversity, divided among nine families.
Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness, species richness, and species diversity are to be obtained first. Species evenness[ 181 ] is the relative number of individuals of each species in a given area.
Plant taxonomy. Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy (the science that finds, describes, classifies, and names living things). Plant taxonomy is closely allied to plant systematics, and there is no sharp boundary between the two.
Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.

Plants are the primary producers in most terrestrial ecosystems and form the basis of the food web in those ecosystems. [82] Plants form about 80% of the world biomass at about 450 gigatonnes (4.4 × 10 11 long tons; 5.0 × 10 11 short tons) of carbon. [83]
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". [ 1 ]
Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. Euphorbias range from tiny annual plants to large and long-lived trees. [2] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more. [3][4] The genus has roughly 2,000 members, [5][6] making it one of the ...
