Ulmus hollandica 'Smithii' commonly known as the Downton Elm was one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with the Field Elm U. minor. The tree was originally planted at Downton Castle[1] near Ludlow as one of a batch raised at Smith's Nursery Worcester England from seeds obtained from a tree in Nottingham in 1810. Some Victorian writers confused 'Smithii' with U. glabra 'Horizontalis' because both featured weeping branches.
