The Field Elm cultivar Ulmus minor 'Rugosa' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. campestris rugosa Kirchner.[1] Kirchner's tree, like Späth's a level-branched suberose field elm, was received from Belgium in 1864 as Ulmus rugosa pendula.[2] Kirchner stressed that it was different from Loudon's Ulmus montana var. rugosa, being "more likely to belong to U. campestris or its subspecies, the Cork-elm".

Green (1964) considered Ulmus rugosa pendula Kirchner a synonym of U. campestris suberosa pendula.[3] Späth, however, listed U. campestris rugosa and U. campestris suberosa pendula as distinct cultivars in his 1903 catalogue,[1] and distributed them separately.[4][5]
It is not known whether herbarium leaf-specimens from the Wageningen Arboretum originally labelled U procera 'Rugosa' and renamed U. carpinifolia (1962) show Späth's tree.[6] They show, however, a different clone from herbarium specimens labelled Ulmus hollandica Mill. rugosa pendula from Arnold Arboretum (1930) (see Ulmus hollandica Mill. Rugosa pendula, under Ulmus 'Rugosa', 'Cultivation').
Neither Kirchner's nor Späth's suberose 'Rugosa' is to be confused with the cultivar Ulmus montana var. rugosa.
