| species = Ulmus glabra | cultivar = 'Corylifolia Purpurea' | origin = Europe }} The Wych Elm cultivar Ulmus glabra 'Corylifolia Purpurea' was raised from seed of 'Purpurea' and described as U. campestris corylifolia purpurea by Pynaert in 1879.[1] An U. campestris corylifolia purpurea was distributed by the Späth nursery of Berlin in the late 19th and early 20th centuries,[2] and by the Hesse Nursery of Weener, Germany, to the 1930s.[3] Green listed 'Corylifolia Purpurea' as a form of U. glabra.[4] DescriptionAccording to Pynaert, 'Corylifolia Purpurea' had large purplish leaves resembling those of Hazel, with the purple colour persisting into autumn on outer branchlets.[1] Pests and diseasesSee under Ulmus glabra. CultivationNo specimens are known to survive. One tree obtained from the Späth nursery in Berlin was planted in 1893 at the Dominion Arboretum, Ottawa, Canada.[5] Three specimens were supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. campestris 'Corylifolia purpurea', and may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[6] A specimen obtained from Späth stood in the Ryston Hall arboretum, Norfolk,[7] in the early 20th century.[8] U. glabra occasionally produces purple-flushed new leaves; an elm in the gardens of the Hedvig Eleonora Church, Östermalm, Stockholm, incorrectly listed as U. procera 'Purpurea', appears in form, fruit and foliage to be a wych elm with a purplish tinge to some leaves.[9] A similarly misnamed 'Purple English Elm' remains in cultivation in Estonia.[10]Synonymy
