Ulmus glabra 'Corylifolia Purpurea'
A specimen at the Ryston Hall , Norfolk, arboretum, obtained from the Späth nursery in Berlin before 1914, was killed by the earlier strain of Dutch elm disease prevalent in the 1930s. Three specimens were also supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. campestris 'Corylifolia purpurea', and may possibly survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).
