"Trees believed to have been extinct in Britain have been discovered at the Queen’s official residence in Scotland.
The two 30-metre (98ft) Wentworth elms have been identified in the Queen’s garden at the Palace of Holyroodhouse just a stone’s throw from the centre of Edinburgh. Tree experts are now looking into ways of propagating the rare specimens, which carry the botanical name Ulmus wentworthii pendula.
Max Coleman, of the Royal Botanic Garden Edinburgh (RBGE), identified the mature trees after they were noted as being unusual during a tree survey."
