UK: Royal Botanic Garden nurtures smallest begonia
Begonia elachista was discovered at the mouth of a limestone cave in a national park in central Peru.
The park authorities want to build a tourist route to the cave - a move which could threaten the species.
Staff at the botanic garden hope their work will inform conservation efforts for the new species which has been classed as critically endangered.
The Peruvian cave is the only place botanists know that the begonia grows in the wild, but the Royal Botanic Garden Edinburgh (RBGE) said it was "not a safe haven" for the plant as more tourists begin to arrive
RBGE staff are now working with partners in Peru and the US to try to save it.
