Many plants facing extinction due to climate change and rising temperatures

More than 2,000 plant species were discovered last year, the first study of their global status has found, but many species are in danger of extinction.

The ‘State of the World’s Plants’ report, by the Royal Botanic Gardens, Kew, estimates that there are 391,000 vascular plants — which exclude mosses and algae — in the world.

New finds include a huge, insect-eating sundew discovered via Facebook, five new types of onion, a 3m-tall slipper orchid, and a close relative of the sweet potato.
