Dendr. 1: 157, 1959. Henry also listed an Ulmus campestris (:U. minor 'Atinia') var. purpurea Petz. & Kirchn., with a description matching that of 'Purpurea', and adding that though it was grown at Kew as U. montana (:glabra) var. purpurea it was \"probably of hybrid origin\".The ancestry of the tree remains obscure, but the fact that 'Purpurea' occasionally produces suckers suggests an Ulmus minor hybrid origin. F. J. Fontaine conjectured U. glabra × U. minor 'Stricta', placing it in the Ulmus × hollandica group. Both the leaves and the habit of 'Purpurea' appear to support this conjecture. However, U. glabra occasionally produces red- or purple-flushed new leaves; an elm in the gardens of the Hedvig Eleonora Church, Östermalm, Stockholm, is listed as Ulmus procera 'Purpurea', but in form, fruit and foliage it appears to be a wych elm with a purplish tinge to its leaves. In Europe there is also a putative small-leaved elm Ulmus minor 'Purpurascens'.In Australia cultivars by the name of U. glabra 'Purpurea', U. procera 'Purpurea' and U. purpurea appear in old nursery catalogues dating from 1886, but these are now believed to be synonymous with the cultivar currently known there as U. × hollandica 'Purpurascens', the name given by F. J. Fontaine to 'Purpurea'. An elm obtained in 1922 from H. Kohankie & Son was listed by the Morton Arboretum, Illinois, as Ulmus procera 'Purpurea', but without description.In North America, purple-leaved elms encountered in the fall are likely to be the new hybrid Ulmus 'Frontier'."@en }
