Ulmus laevis
In 1997, a large European White Elm "Ulmus laevis" growing in the Ladywell Fields public park in Lewisham, London, was misidentified as a 'Klemmer' elm; an information board erected in front of the tree by Lewisham Council, still (2018) bears the erroneous name, and depicts another tree (one of the Morton 'Klemmer').
