The hybrid elm cultivar Ulmus × hollandica 'Wredei', also known as Ulmus × hollandica 'Dampieri Aurea' and sometimes marketed as Golden Elm, originated as a sport of the cultivar 'Dampieri' at the Alt-Geltow Arboretum, near Potsdam, Germany, in 1875.
The Wych Elm cultivar Ulmus glabra 'Lutescens', commonly known as the Golden Wych Elm, arose as a sort of a wych found in the York area in the early 19th century by W. Pontey of Pontey's nursery, Kirkheaton, Huddersfield, who propagated and distributed it. The original tree he named the Gallows Elm for its proximity to a gallows near York. Loudon in The Gardener's Magazine (1839) identified it as a form of Ulmus montana, adding 'Lutescens' by analogy with Corstorphine sycamore, Acer pseudoplatanus 'Lutescens'.
The Field Elm cultivar Ulmus minor 'Viminalis Aurea', probably a "golden" form of Ulmus minor 'Viminalis', was raised before 1866 by Egide Rosseels of Louvain, who was known to have supplied 'Viminalis'.
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 '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 so-called American Elm cultivar Ulmus americana 'Variegata' was a Belgian clone mentioned by Wesmael in Bulletin de la Fédération des sociétés d'horticulture de Belgique, 1862, as Ulmus americana var. variegataHort. It was marketed by the Baudriller nursery of Angers as U. americana foliis variegatis. Wesmael's herbarium specimens, however, held in the Botanic Garden, Meise, both of his Ulmus americana and of his Ulmus americana var. variegata, do not appear to show American white elm leaves. It is known that nurseries in Europe and America marketed the golden wych elm Ulmus glabra 'Lutescens' as Ulmus americana aurea, and it is likely that Wesmael's Ulmus americana variegata was similarly misnamed, and perhaps derived from a reverting branch of aurea, whose leaves it resembled.
The putative Wych Elm cultivar Ulmus glabra 'Corylifolia' was first described by Host in Flora Austriaca (1827). Another cultivar of the same name is described by Hugo Zapalowicz in Conspectus Florae Galiciae Criticus (1908), but was assumed to be 'Cornuta'. Herbarium specimens confirm that more than one clone has been labelled 'Corylifolia', some with longish petioles and with fruit more typical of Ulmus × hollandica hybrids.
The putative Wych Elm cultivar Ulmus glabra 'Fastigiata Macrophylla' was first mentioned by Dieck in the Zöschen catalogue in 1885 as Ulmus montana forma fastigiata macrophylla, without description. Hartwig added a description in 1892. Berndt received "from a renowned nursery in Holstein" an Ulmus montana fastigiata macrophylla, possibly the same clone, in 1903, which he listed and described as Ulmus glabra fastigiata in Graf von Schwerin's Mitteilungen der Deutschen Dendrologischen Gesellschaft (1915).
The Wych Elm cultivar Ulmus glabra 'Latifolia Aurea' was listed by Schelle in Beissner et al, Handbuch der Laubholz-Benennung (1903), as Ulmus glabraMillerlatifolia aurea, but without description. In the Netherlands in the late 19th and early 20th centuries, however, Ulmus montana latifolia aurea was a synonym of the wych cultivar 'Lutescens', and Green reclassified Schelle's 'Latifolia aurea' as a form of U. glabraHudson.
The European White Elm cultivar Ulmus laevis 'Aureovariegata', a yellow-variegated form, may have been the tree first listed, without description, in Hortus Regius Monacensis (1829) as Ulmus effusa variegata, grown at the Munich Botanic Garden. An Ulmus effusa fol. variegatis (Hort.) was first described c.1890 by the Späth nursery of Berlin, which distributed the tree in the late 19th century. The name U. effusa f. aureovariegata appeared in Beissner and Schelle's Handbuch der Laubholz-Benennung, 1903, without description.
The European White Elm cultivar Ulmus laevis 'Punctata' was mentioned in 1873, 1889, and later in 1903 as U. effusa f. punctata, but without description.
The Field Elm cultivar Ulmus minor 'Viminalis Pulverulenta' (:'powdery'), also known as 'Viminalis Variegata', a variegated form of U. minor 'Viminalis', was first mentioned by Dieck, in 1885 as U. scabra viminalis pulverulentaHort., but without description. Nursery, arboretum, and herbarium specimens confirm that this cultivar was sometimes regarded as synonymous with U. minor 'Viminalis Marginata', first listed in 1864, which is variegated mostly on the leaf margin. It is likely, however, that 'Pulverulenta' was the U. 'Viminalis Variegata', Variegated Twiggy-branched elm, that was listed and described by John Frederick Wood, F.H.S., in The Midland Florist and Suburban Horticulturist 1847 and 1851, pre-dating both Kirchner and Dieck. Wood did not specify the nature of the variegation.
The elm cultivar Ulmus 'Nemoralis' was listed by Schelle in Beissner et al. (1903), as U. campestris f. nemoralisHort. Considered "possibly U. carpinifolia " by Green.
Ulmus × hollandica 'Wentworthii Pendula', commonly known as the Wentworth Elm or Wentworth Weeping Elm, is a cultivar with a distinctive weeping habit that appears to have been introduced to cultivation towards the end of the 19th century. The tree is not mentioned in either Elwes and Henry's or Bean's classic works on British trees. The earliest known references are Dutch and German, the first by de Vos in Handboek tot de praktische kennis der voornaamste boomen (1890). At about the same time, the tree was offered for sale by the Späth nursery of Berlin as Ulmus Wentworthi pendulaHort.. The 'Hort.' in Späth's 1890 catalogue, without his customary label "new", confirms that the tree was by then in nurseries as a horticultural elm. De Vos, writing in 1889, states that the Supplement to Volume 1 includes entries announced since the main volume in 1887, putting the date of introduction between 1887 and 1889.
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 Field Elm cultivar Ulmus minor 'Cucullata Variegata', a variegated form of U. minor 'Cucullata', was listed by C. de Vos, in 1867, as U. americana cucullata folia variegata and by Schelle in Beissner Handbuch der Laubholz-Benennung, 82 (1903) as U. campestris concavifolia cucullata variegataHort, without description.
The field elm cultivar Ulmus minor 'Viminalis' (:'willow-like'), occasionally referred to as the twiggy field elm, was raised by Masters in 1817, and listed in 1831 as U. campestris viminalis, without description. Loudon added a general description in 1838, and the Cambridge University Herbarium acquired a leaf specimen of the tree in 1866. Moss, writing in 1912, said that the Ulmus campestris viminalis from Cambridge University Herbarium was the only elm he thought agreed with the original Plot's elm as illustrated by Dr. Plot in 1677 from specimens growing in an avenue and coppice at Hanwell near Banbury. Elwes and Henry (1913) also considered Loudon's Ulmus campestris viminalis to be Dr Plot's elm. Its 19th-century name, U. campestris var. viminalis, led the cultivar to be classified for a time as a variety of English Elm. On the Continent, 'Viminalis' was the Ulmus antarcticaHort., 'zierliche Ulme' [:'dainty elm'] of Kirchner's Arboretum Muscaviense (1864).
The Field Elm cultivar Ulmus minor 'Monumentalis', the tomb elm (Grabmal-Rüster), was raised as a sucker of U. suberosa by Sebastian Rinz, the city gardener of Frankfurt, before 1855 and listed by the Jacob-Makoy nursery of Liège in their 1861 catalogue as Ulmus monumentalisRinz, "a new variety". Kirchner (1864) described it, confirming that it had only recently been propagated by Rinz and established in the nursery. It was distributed from the 1880s by the Baudriller nursery, Angers, and by the Späth nursery, Berlin, as U. campestris monumentalisRinz., appearing separately in their catalogues from U. minor 'Sarniensis', the Guernsey or Wheatley Elm, with which, according to Henry, it was confused on the continent. Krüssmann, for example, gives 'Monumentalis' as a synonym of 'Sarniensis'. 'Sarniensis' is known as monumentaaliep [:monumental elm] in The Netherlands. Springer noted that the Dutch monumentaaliep was "not the actual monumentaaliep but U. glabraMill.var. Wheatleyi Sim. Louis", and that it "should be renamed U. glabraMill. var. monumentalisHort.(non Rinz)". In England, Smith's of Worcester listed Ulmus monumentalis separately from Ulmus 'Wheatley' in the 1880s.
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).
