|Hybrid parentage||U. glabra × U. minor|
The hybrid elm cultivar Ulmus × hollandica 'Gaujardii', one of a number of cultivars arising from the crossing of Wych Elm U. glabra with Field Elm U. minor, was raised by the Gaujard-Rome nursery of Châteauroux, France, in the 1890s as Ulmus Gaujardii and was described in the 1898 Kew Bulletin and Wiener illustrirte Garten-Zeitung.It won first prize in the International Horticultural Exhibition in Saint Petersburg, Russia, in 1899 and a silver medal in the Heemstede Exhibition, The Netherlands, in 1925. From the early 20th century it was distributed by the Späth nursery of Berlin as Ulmus montana Gaujardi, and in the interwar years by the Boccard nursery of Geneva as Ulmus campestris Gaujardi. It appeared in Unsere Freiland-Laubgehölze in 1913, but without description.
A tree of symmetrical upright growth and of great vigour, with the appearance of an arrow. The foliage was of medium size, oval and light green.Four photographs of 'Gaujardii' appear in Pépinières Gaujard-Rome et Cie (1930), where the nursery distinguished between medium- and large-leaved forms. Herbarium specimens suggest that more than one clone has been labelled 'Gaujardii' (see 'External links').
Elms of the U. × hollandica group are susceptible to Dutch elm disease.
'Gaujardii' was produced at a rate of 30,000 trees per annum by 1930,though no specimens are known to survive. There was a specimen at Arnold Arboretum, Massachusetts, in the mid-20th century (see 'External links').
An old U. × hollandica with leaves (unusually for this group) light green all summer and matching the 'Gaujardii' herbarium specimen in The Hague,stands (2019) by 35 Inverleith Terrace, Edinburgh, near the entrance to Royal Botanic Garden. An early 20th century photograph shows it fastigiate when young. Its leaf-shape, samarae, and light suckering confirm its hybridity.
The hybrid elm cultivar Ulmus × hollandica 'Belgica', one of a number of hybrids arising from the crossing of Wych Elm with a variety of Field Elm, was reputedly raised in the nurseries of the Abbey of the Dunes, Veurne, in 1694. Popular throughout Belgium and the Netherlands in the 19th century both as an ornamental and as a shelter-belt tree, it was the 'Hollandse iep' in these countries, as distinct from the tree known as 'Dutch Elm' in Great Britain and Ireland since the 17th century: Ulmus × hollandica 'Major'. In Francophone Belgium it was known as orme gras de Malines.
The elm cultivar Ulmus 'Monstrosa' [: "monstrous", "strange"], a shrub-elm with fasciated branching, is believed to have originated in France, where it was first listed by Lavallée in Arboretum Segrezianum (1877) as a form of Field Elm, Ulmus campestris var. monstrosa, but without description. Though its long slender 2 cm petiole is not a feature of wych elm U. glabraHuds., and is even less likely in a shrub form of this species, the wych-cultivar error arose early, perhaps because the Späth nursery of Berlin, using Ulmus montana both for some Ulmus × hollandica cultivars and for wych varieties, listed it c.1890 as Ulmus montana monstrosa. Hartwig in Illustrirtes Gehölzbuch (1892) followed with Ulmus scabra monstrosa, an error repeated by Krüssman (1962) and by Green (1964), with their U. glabraHuds. 'Monstrosa'.
Ulmus minor 'Rueppellii' is a Field Elm cultivar said to have been introduced to Europe from Tashkent by the Späth nursery, Berlin. Noted in 1881 as a 'new elm', it was listed in Späth Catalogue 73, p. 124, 1888–89, and in subsequent catalogues, as Ulmus campestris Rueppelli, and later by Krüssmann as a cultivar.
The elm cultivar Ulmus 'Berardii', Berard's Elm, was raised in 1865, as Ulmus Berardi, from seeds collected from large specimens of "common elm" growing on the ramparts at Metz, by an employee of the Simon-Louis nursery named Bérard. Carrière (1887), the Späth nursery of Berlin and the Van Houtte nursery of Gentbrugge regarded it as form of a Field Elm, listing it as U. campestris Berardii, the name used by Henry. Cheal's nursery of Crawley distributed it as Ulmus nitens [:Ulmus minor] 'Berardii'. Smith's of Worcester preferred the original, non-specific name, Ulmus 'Berardii'.
The elm cultivar Ulmus 'Koopmannii' was cloned from a specimen raised from seed sent from Margilan, Turkestan by Koopmann to the Botanischer Garten Berlin c. 1880. Noted in 1881 as a 'new elm', it was later listed by the Späth nursery, catalogue no. 62, p. 6. 101, 1885, as Ulmus Koopmannii, and later by Krüssmann in 1962 as a cultivar of U. minor. Margilan is beyond the main range of Ulmus minor. Augustine Henry, who saw the specimens in Berlin and Kew, believed Koopmann's Elm to be a form of Ulmus pumila, a view not shared by Rehder of the Arbold Arboretum. Ascherson & Graebner said the tree produced 'very numerous root shoots', which suggests it may be a cultivar of U. minor. Until DNA analysis can confirm its origin, the cultivar is now treated as Ulmus 'Koopmannii'.
The putative Wych Elm cultivar Ulmus glabra 'Dovaei', or Doué elm, was raised by the André Leroy nursery at Angers, France, as Ulmus dovaei, before 1868. The Baudriller nursery of Angers marketed it as Ulmus Dowei, "orme de Doué", suggesting a link with the royal nurseries at nearby Doué-la-Fontaine, which stocked elm. Green considered it a form of wych.
The elm cultivar Ulmus 'Escaillard' was first described by Dumont de Courset in 1811, and listed, without description, as Ulmus escaillard, by the André Leroy nursery at Angers, France, in 1849. It was distributed by the Baudriller nursery of Angers and by Hesse's nursery, Weener, Germany, as U. campestris 'Escaillardii', both nurseries using U. montana for wych elm cultivars. Herbarium specimens from a tree in The Hague obtained from the Hesse nursery label it variously U. glabra 'Escaillardii' and Ulmus × hollandica 'Escaillardi'. The latter was Christine Buisman's determination (1931), identifiable as hers by its handwriting and red label.
The elm cultivar Ulmus 'Rugosa' [:'wrinkled', the leaves], was first listed in Audibert's Tonelle (1817), as "U. campestris Linn. 'Rugosa' = orme d'Avignon [Avignon elm] ", but without description. A description followed in the Revue horticole, 1829. Green (1964) identified this cultivar with one listed by Hartwig and Rümpler in Illustrirtes Gehölzbuch (1875) as Ulmus montana var. rugosaHort.. A cultivar of the same name appeared in Loddiges' catalogue of 1836 and was identified by Loudon in Arboretum et Fruticetum Britannicum (1838) as Ulmus montana var. rugosaMasters, Masters naming the tree maple-bark elm. Ulmus montana was used at the time both for wych cultivars and for some cultivars of the Ulmus × hollandica group.
The Elm cultivar Ulmus 'Tiliaefolia' was first mentioned by Host in Flora Austriaca (1827), as Ulmus tiliaefolia [:linden-leaved]. The Späth nursery of Berlin distributed a 'Tiliaefolia' from the late 19th century to the 1930s as neither an U. montana hybrid nor a field elm cultivar, but simply as Ulmus tiliaefolia, suggesting uncertainty about its status. Herbarium specimens appear to show two clones, one smaller-leaved and classified as a field elm cultivar, the other larger-leaved.
Ulmus × hollandica 'Klemmer', or Flanders Elm, is probably one of a number of hybrids arising from the crossing of Wych Elm with a variety of Field Elm, making it a variety of Ulmus × hollandica. Originating in the Bruges area, it was described by Gillekens in 1891 as l'orme champêtre des Flandres in a paper which noted its local name, klemmer, and its rapid growth in an 1878–91 trial. Kew, Henry (1913), and Krüssmann (1976) listed it as an Ulmus × hollandica cultivar, though Henry noted its "similarity in some respects" to field elm Ulmus minor, while Green went as far as to regard it as "possibly U. carpinifolia" (:minor).
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 hybrid elm cultivar Ulmus × hollandica 'Superba' is one of a number of intermediate forms arising from the crossing of the Wych Elm U. glabra with a variety of Field Elm U. minor. Boulger tentatively (1881) and Green more confidently (1964) equated it with a hybrid elm cultivated in the UK by Masters at Canterbury in the early 19th century, known as "Masters' Canterbury Seedling" or simply the Canterbury Elm. Loudon examined a specimen sent by Masters and considered it a hybrid, calling it U. montana glabra major.
The hybrid elm cultivar Ulmus × hollandica 'Dumont' was a very vigorous elm raised from a tree discovered by a gardener on the estate of M. Dumont at Tournay, Belgium, c. 1865.
The putative Wych Elm cultivar Ulmus glabra 'Latifolia' was identified in Audibert's Tonelle (1817) as U. campestrisLinn. [ = U. glabraHuds.] latifolia. The tree is reputed to have originated circa 1750 in or around Mechelen, and to have been widely planted throughout Belgium. A 1912 herbarium specimen from Oudenbosch, however, shows a hybrid leaf labelled Ulmus hollandica latifolia.
The elm cultivar Ulmus 'Lombartsii' is considered "possibly Ulmus × hollandica or Ulmus carpinifolia " by Green (1964). The tree was raised by Lombarts Nurseries at Zundert, Netherlands, circa 1910.
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 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".
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 Field Elm cultivar Ulmus minor 'Suberosa', commonly known as the Cork-barked elm, is a slow-growing or dwarf form of conspicuously suberose Field Elm. Of disputed status, it is considered a distinct variety by some botanists, among them Henry (1913), Krüssmann (1984), and Bean (1988), and is sometimes cloned and planted as a cultivar. Henry said the tree "appears to be a common variety in the forests of central Europe", Bean noting that it "occurs in dry habitats". By the proposed rule that known or suspected clones of U. minor, once cultivated and named, should be treated as cultivars, the tree would be designated U. minor 'Suberosa'. The Späth nursery of Berlin distributed an U. campestris suberosa alataKirchn. [:'corky-winged'] from the 1890s to the 1930s.
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.
