The plant can only be found in three places in the UK
One of Britain's rarest plants has been planted in the grounds of a public school in Surrey.
Starved wood-sedge has been reintroduced to Charterhouse School in Godalming, where it has not been seen since the 1940s.
The plant is found in two other places in the UK - in woodland near Godalming railway station and in Somerset.
The charity, Plantlife, said the prospects of saving the plant from extinction are now "looking brighter".
The plant used to grow at Charterhouse School before World War II, but then disappeared.
Dominic Price, the charity's species recovery officer, said: "It is a rare step for Plantlife to consider re-introducing a population of rare plants.
"In this case, the national outlook for the plants was so critical that we needed to throw a lifeline."
