Origin | Europe |
The European White Elm cultivar Ulmus laevis 'Colorans' was listed as U. effusa (: laevis) var. colorans by Kirchner [1] in Petzold [2] & Kirchner, Arboretum Muscaviense (1864). [3]
Peter Shaw Green (1964) suggested that Herder's U. campestrisLinn.rubescens, described in Gartenflora (1871), [4] by its name a wych elm cultivar with "reddening leaves", from Yelagin Island, may have been an earlier listing of a 'Colorans'-type U. laevis under a mistaken species name. [5]
The tree was described by Kirchner as having leaves turning a rich scarlet red in autumn, not golden yellow. [3] [5]
'Colorans' was rare in cultivation. Kirchner planted two specimens in the Arboretum Muscaviense. [3] A tree said to be of this type stood near Hailsham, East Sussex, UK (on the Cuckoo Trail); regrowth from it survives there (2006). The tree is not known to remain in cultivation elsewhere.
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 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 Wych Elm cultivar Ulmus glabra 'Tomentosa' was first listed as Ulmus tomentosa by Kirchner in Arboretum Muscaviense (1864). The Hesse Nursery of Weener, Germany, distributed an Ulmus montana tomentosa in the 1930s. Green listed it as a wych elm cultivar.
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 Field Elm cultivar Ulmus minor 'Umbraculifera Gracilis' was obtained as a sport of 'Umbraculifera' by the Späth nursery of Berlin c.1897. It was marketed by the Späth nursery in the early 20th century, and by the Hesse Nursery of Weener, Germany, in the 1930s.
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 Field Elm cultivar Ulmus minor 'Purpurascens' was listed by Lavallée in Arboretum Segrezianum (1877) as U. campestris var. purpurascens (purpurea), but without description, and later by Schneider in Illustriertes Handbuch der Laubholzkunde (1904). Krüssmann in Handbuch der Laubgehölze (1962) identified it as a cultivar.
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 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).
