The Field Elm cultivar Ulmus minor 'Viminalis Marginata', a variegated form of Ulmus minor 'Viminalis', was first listed as Ulmus campestris var. viminalis marginataHort. by Kirchner in 1864. Both Van Houtte and Späth marketed an U. campestris viminalis marginata in the late 19th century.
The elm cultivar Ulmus 'Purpurea', the purple-leaved elm, was listed and described as Ulmus Stricta Purpurea, the 'Upright Purpled-leaved Elm', by John Frederick Wood, F.H.S., in The Midland Florist and Suburban Horticulturist (1851), as Ulmus purpureaHort. by Wesmael (1863), and as Ulmus campestris var. purpurea, syn. Ulmus purpureaHort. by Petzold and Kirchner in Arboretum Muscaviense (1864). Koch's description followed (1872), the various descriptions appearing to tally. Henry (1913) noted that the Ulmus campestris var. purpureaPetz. & Kirchn. grown at Kew as U. montana var. purpurea was "probably of hybrid origin", Ulmus montana being used at the time both for wych elm cultivars and for some of the U. × hollandica group. His description of Kew's U. montana var. purpurea matches that of the commonly-planted 'Purpurea' of the 20th century. His discussion of it (1913) under U. campestris, however, his name for English Elm, may be the reason why 'Purpurea' is sometimes erroneously called U. procera 'Purpurea' (as in USA and Sweden.
The Wych Elm cultivar Ulmus glabra 'Cornuta', in cultivation before 1845 – Fontaine (1968) gives its provenance as France, 1835 – is a little-known tree, finally identified as a cultivar of U. glabra by Boom in Nederlandse Dendrologie 1: 157, 1959.
The elm cultivar Ulmus 'Crispa' [:'curled', the leaf margin], sometimes known as the Fernleaf Elm, arose before 1800 and was first listed by Willdenow as U. crispa (1809). Audibert listed an U. campestrisLinn. 'Crispa', orme à feuilles crépues [:'frizzy-leaved elm'], in 1817, and an Ulmus urticaefolia [:'nettle-leaved elm'] in 1832; the latter is usually taken to be a synonym. Loudon considered the tree a variety of U. montana (1838). In the 19th century, Ulmus × hollandica cultivars, as well as those of Wych Elm, were often grouped under Ulmus montana. Elwes and Henry (1913) listed 'Crispa' as a form of wych elm, but made no mention of the non-wych samara.
The Field Elm cultivar Ulmus minor 'Propendens', described by Schneider in 1904 as U. glabra (:minor) var. suberosa propendens, Weeping Cork-barked elm, was said by Krüssmann (1976) to be synonymous with the U. suberosa pendula listed by Lavallée without description in 1877. Earlier still, Loudon's Arboretum et Fruticetum Britannicum had included an illustration of a pendulous "cork-barked field elm", U. campestris suberosa. An U. campestris suberosa pendula was in nurseries by the 1870s.
The Field Elm cultivar Ulmus minor 'Webbiana', or Webb's curly-leaf elm, distinguished by its unusual leaves that fold upwards longitudinally, was said to have been raised at Lee's Nursery, Hammersmith, London, circa 1868, and was first described in that year in The Gardener's Chronicle and The Florist and Pomologist. It was marketed by the Späth nursery of Berlin in the late 19th and early 20th centuries as U. campestris WebbianaHort., and by Louis van Houtte of Ghent as U. campestris crispa (Webbiana). Henry thought 'Webbiana' a form of Cornish Elm, adding that it "seems to be identical with the insufficiently described U. campestris var. concavaefoliaLoudon" – a view repeated by Krüssmann.
The Wych Elm cultivar Ulmus glabra 'Nigra', commonly known as the Black Irish Elm, was found in the Kilkenny area c.1770 by the father of nurseryman John Robertson of Kilkenny, who later cultivated it. Robertson stated that he had not seen the form outside Ireland. It was listed by Loddiges (1830) as Ulmus nigra, and described by Loudon in Arboretum et Fruticetum Britannicum (1838), as Ulmus montana nigra. 'Nigra' is not mentioned in either Elwes and Henry's or Bean's classic works on British trees.
The European White Elm cultivar Ulmus laevis 'Colorans' was listed as U. effusa var. colorans by Kirchner in Petzold & Kirchner, Arboretum Muscaviense (1864).
The Field Elm cultivar Ulmus minor 'Concavaefolia' was briefly described by Loudon in Arboretum et Fruticetum Britannicum (1838), as Ulmus campestris var. concavaefolia. A fuller description followed in Petzold and Kirchner 's Arboretum Muscaviense (1864). Henry noted that Loudon's "insufficiently described" U. campestris var. concavaefolia seemed to be identical with the field elm cultivar 'Webbiana', a view repeated by Krüssmann.
The Field Elm cultivar Ulmus minor 'Cucullata', the Hooded elm, was listed by Loddiges of Hackney, London, in their catalogue of 1823 as Ulmus campestris cucullata, and later by Loudon in Arboretum et Fruticetum Britannicum (1838), as U. campestris var. cucullata.
Ulmus × hollandica 'Pitteurs' or 'Pitteursii', one of a number of hybrid cultivars arising from the crossing of the Wych Elm Ulmus glabra with a variety of Field Elm Ulmus minor, was first identified by Morren as l'orme Pitteurs (1848). Elwes and Henry (1913) and Krüssmann (1976) listed it as an Ulmus × hollandica cultivar. It was named after the landowner Henri Bonaventure Trudon de Pitteurs of Saint-Trond, near Liège, Belgium, who discovered and first propagated the tree on his estate.
The elm cultivar Ulmus 'Alata' was first mentioned by Kirchner, in Petzold & Kirchner, Arboretum Muscaviense 566, 1864, as Ulmus montana alata, but without description.
Ulmus × hollandica 'Alba' is one of a number of hybrids arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor. First mentioned by Kirchner in 1864 as U. fulvaHort. var. alba.
The Field Elm cultivar Ulmus minor 'Microphylla Pendula', the Weeping small-leaved elm, was first listed by the Travemünde nursery, Lübeck, and described by Kirchner in Petzold & Kirchner's Arboretum Muscaviense (1864), as Ulmus microphylla pendulaHort.. By the 1870s it was being marketed in nurseries in Europe and America as Ulmus campestris var. microphylla pendula.
The elm cultivar Ulmus 'Scampstoniensis', the Scampston Elm or Scampston Weeping Elm, is said to have come from Scampston Hall, Yorkshire, England, before 1810. Loudon opined that a tree of the same name at the Royal Horticultural Society's Garden in 1834, 18 feet (5.5 m) high at 8 years old "differed little from the species". Henry described the tree, from a specimen growing in Victoria Park, Bath, as "a weeping form of U. nitens" [:Ulmus minor ]; however Green considered it "probably a form of Ulmus × hollandica". Writing in 1831, Loudon said that the tree was supposed to have originated in America. U. minor is not, however, an American species, so if the tree was brought from America, it must originally have been taken there from Europe. There was an 'American Plantation' at Scampston, which may be related to this supposition. A number of old specimens of 'Scampstoniensis' in this plantation were blown down in a great gale of October 1881; younger specimens were still present at Scampston in 1911.
The hybrid elm cultivar Ulmus × hollandica 'Elegantissima' was the name given by A. R. Horwood in his Flora of Leicestershire and Rutland (1933) to an elm found in those counties and later identified by Melville as a natural hybrid between Wych Elm and Plot Elm. According to Melville, the hybrid occurs in the main areas of Plot Elm distribution, where it is more common than Plot Elm itself. The tree is sometimes known simply as the 'Midlands Elm'.
The Field Elm cultivar Ulmus minor 'Rugosa' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. campestris rugosaKirchner. Kirchner's tree, like Späth's a level-branched suberose field elm, was received from Belgium in 1864 as Ulmus rugosa pendula. 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".
The hybrid elm cultivar Ulmus × hollandica 'Fastigiata' was first listed and described as Ulmus glabra fastigiata, a narrow-crowned elm with large smooth leaves, by Petzold and Kirchner in Arboretum Muscaviense (1864). C. Berndt of the Berndt Nursery, Zirlau, Schweidnitz, described an elm of the same name in Mitteilungen der Deutschen Dendrologischen Gesellschaft, that he had received in 1903 "from a renowned nursery in Holstein" as Ulmus montana fastigiata macrophylla. A tree of that name had been listed by Dieck in 1885 without description. Berndt reported that his U. glabra fastigiata was "easy to confuse with U. montana superba", a tree "known in the Magdeburg region as Ulmus praestans", a statement confirming that, like that cultivar, his tree was a form of U. × hollandica. Karl Gustav Hartwig who received specimens of U. praestans from Kiessling of the Magdeburg city nursery in 1908, concluded (1912) that U. glabra fastigiataKirchner was indistinguishable in leaf or habit from U. praestans. An U. campestris glabra fastigiataArb. Musc. [ = Kirchner] was distributed by the Hesse Nursery, Weener, Germany, in the 1930s, where it was listed separately from U. praestans.
The Wych Elm cultivar Ulmus glabra 'Gigantea' was listed as U. montana var. giganteaHort. by Kirchner (1864). An U. montana gigantea was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s. It did not appear in Späth's 1903 catalogue. A specimen at Kew was judged by Henry to be "not distinct enough to deserve a special name". Both Späth and the Hesse Nursery of Weener, Germany, supplied it in the 1930s.
The Wych Elm cultivar Ulmus glabra 'Concavaefolia', a form with up-curling leaves, was listed in Beissner's Handbuch der Laubholz-Benennung (1903) as Ulmus montana cucullataHort. [:'hooded', the leaf], a synonym of the Ulmus scabraMill. [:glabraHuds.] var. concavaefolia of herbarium specimens. An Ulmus campestris cucullata, of uncertain species, had appeared in Loddiges' 1823 list, but Loudon's brief description (1838) of concave- and hooded-leaved elms was insufficient for later botanists to distinguish them. The earliest unambiguous description appears to be that of Petzold and Kirchner in Arboretum Muscaviense (1864).
