Kew Gardens has published its first State of the World’s Plants report. The document was produced by a large team of researchers who combed through databases to organize worldwide botanical knowledge into three categories: what we currently know about global plant populations; identified plant threats; and international plant trade.
Scientists now know there are approximately 391,000 vascular plant species, of which 31,128 have a documented use (see “Plants by the Numbers,” below). The top three countries for identifying new plant species are Brazil, Australia, and China. In 2015 alone, 2,034 new plant species were discovered, including the Drosera magnifica, a carnivorous sundew that can grow to nearly 5 feet tall.
