Origin | Europe |
The Wych Elm cultivar Ulmus glabra 'Concavaefolia' (Fontaine, 1968), [1] a form with up-curling leaves, was listed in Beissner's Handbuch der Laubholz-Benennung (1903) as Ulmus montana cucullataHort. [:'hooded', the leaf], [2] a synonym of the Ulmus scabraMill. [:glabraHuds.] var. concavaefolia of herbarium specimens. [3] An Ulmus campestris cucullata, of uncertain species, had appeared in Loddiges' 1823 list, [4] but Loudon's brief description (1838) of concave- and hooded-leaved elms [5] was insufficient for later botanists to distinguish them. [6] The earliest unambiguous description appears to be that of Petzold and Kirchner in Arboretum Muscaviense (1864). [7]
Not to be confused with the field elm cultivar 'Webbiana', which also has longitudinally-folded, up-curling leaves (though smaller, shallower-toothed, and with longer petiole), or with concave-leaved field elms with down-curling leaves (see U. minor 'Concavaefolia' and U. minor 'Cucullata').
Petzold and Kirchner in Arboretum Muscaviense (1864) described the leaves of their Ulmus campestris cucullata as rough, up-curving, and bicorne-shaped, being longer and more "closed" than those of their Ulmus campestris concavaefolia (the description of which matches 'Webbiana'). The twigs had scattered hairs. [7] The Kissena nurseries (Parsons & Sons) of New York (1903) described the leaves of their Ulmus campestris cucullata as "deeply curled like a hood, and sharply notched along the edges". [8] Both descriptions match the U. glabraHuds. 'Concavaefolia' of Fontaine (1968), with its leaf folded lengthwise along the midrib, making it more or less tubular. [1] Herbarium specimens show an up-curling wych leaf with a shorter petiole, more deeply toothed margin, and more acuminate apex than 'Webbiana'. [9] The samara was confirmed by the Royal Botanic Garden Edinburgh in 2017 as U. glabraHuds.. [10]
The tree is susceptible to Dutch elm disease.
Though once cultivated in Europe and North America, only one specimen of 'Concavaefolia' is now known to survive (see 'Notable trees'). The cultivar was marketed as Ulmus montana cucullataHort. by the van Houtte nursery of Ghent in the late 19th century, [11] the name used for the specimen at Kew Gardens. [12] 'Concavaefolia' may have been the Ulmus campestris cucullata distributed by the Späth nursery of Berlin in the late 19th and early 20th century (to go by Späth's description of hooded grey leaves) [13] [14] and supplied by him to the Dominion Arboretum, Ottawa, Canada (one tree, 1897), [15] to the Royal Botanic Garden Edinburgh (three trees, 1902), [16] and to the Ryston Hall arboretum, Norfolk (one tree, 1916). [17] [18] The tree was introduced to the USA c.1871, appearing as Ulmus campestris cucullata in the catalogues of the Mount Hope Nursery (also known as Ellwanger and Barry) of Rochester, New York, [19] the name by which it was marketed by the Kissena nurseries, N.Y. [8] The cultivar was also marketed by Trumbull and Beebe's nursery, San Francisco, in the 1890s, as "Cucullata: a new variety, with leaves deeply curled like a hood, and sharply notched along the edges". [20] It is not known to have been introduced to Australia or New Zealand.
'Concavaefolia' has been included in the propagation programme (2017) of Royal Botanic Garden Edinburgh. [21]
A specimen stood till 2017 (girth 2.8 m) in East Preston Street Cemetery, Edinburgh, before succumbing to DED. [22] [23] A second, decayed old tree in Warriston Cemetery, Edinburgh, is the remains (2019) of an Ulmus glabra 'Horizontalis' grafted at 2 m on a stock of 'Concavaefolia'. [note 1] The stock, now 3 m in girth (2016), flushes before the scion on a few ascending branches and bole shoots. It produces no suckers.
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 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 'Atropurpurea' [:dark purple] was raised from seed at the Späth nursery in Berlin, Germany, circa 1881, as Ulmus montana atropurpurea, and was marketed there till the 1930s, being later classed as a cultivar by Boom. Henry (1913) included it under Ulmus montana cultivars but noted that it was "very similar to and perhaps identical with" Ulmus purpureaHort. At Kew it was renamed U. glabraHuds. 'Atropurpurea', but Späth used U. montana both for wych elm and for some U. × hollandica hybrids, so his name does not necessarily imply a wych elm cultivar. The Hesse Nursery of Weener, Germany, however, which marketed 'Atropurpurea' in the 1950s, listed it in later years as a form of U. glabraHuds..
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 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 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 'Corylifolia Purpurea' was raised from seed of 'Purpurea' and described as U. campestris corylifolia purpurea by Pynaert in 1879. An U. campestris corylifolia purpurea was distributed by the Späth nursery of Berlin in the late 19th and early 20th centuries. The Hesse Nursery of Weener, Germany, corrected the U. campestris corylifolia purpurea of their 1930s' lists to U. glabraHuds.corylifolia purpurea by the 1950s. Green listed 'Corylifolia Purpurea' as a form of U. glabra.
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 'Louis van Houtte' is believed to have been first cultivated in Ghent, Belgium circa 1863. It was first mentioned by Franz Deegen in 1886. It was once thought a cultivar of English Elm Ulmus minor 'Atinia', though this derivation has long been questioned; W. J. Bean called it "an elm of uncertain status". Its dissimilarity from the type and its Belgian provenance make the 'Atinia' attribution unlikely. Fontaine (1968) considered it probably a form of U. × hollandica.
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 hybrid elm cultivar Ulmus × hollandica 'Modiolina', or Wheel-hub elm, was probably the large-leaved 'Orme tortillard' first described by Duhamel in De l'exploitation des bois (1764). Poederlé (1774) identified the tree as the 'orme maigre' growing in the region that later became part of Belgium. Dumont de Courset described a small-leaved U. campestris var. modiolina, "l'orme tortillard" in 1802 – the first use of the name 'Modiolina'. 'L'orme Tortillard', also known as 'l'orme à moyeux', was considered in France to be the best elm for use by wheelwrights, its timber especially suitable for hubs of wheels. Van Houtte marketed an U. campestris modiolina (tortuosa), and Späth an U. campestris modiolina, from the late 19th century. U. campestris var. modiolinaHort was confirmed as a hybrid by Chevalier in Les Ormes de France (1942) and called U. × 'Modiolina', 'l'orme à moyeux'.
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 '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 elm cultivar Ulmus 'Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. glabraMill.. Not to be confused with the species U. glabraHuds..
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 glabraHuds. 'Superba', Blandford Elm, with unusually large leaves, was raised by Gill's of Blandford Forum, Dorset, in the early 1840s as Ulmus montana superba and was quickly distributed to other UK nurseries. It was confirmed as a form of wych, and first described by Lindley in The Gardeners' Chronicle, 1845, later descriptions being added by Gill (1845) and Morren (1848), who called it U. montana var. superba. Morren had adopted the name 'Superba' from the Fulham nurseryman Osborne in 1844, who supplied him with the tree – presumably one of the nurseries supplied by Gill. Morren states that 'Superba', already in cultivation in England, was introduced to Belgium by Denis Henrard of Saint Walburge, Liège, that in 1848 it had been present in Belgium for only three years, and that this variety was the one described as 'Superba' by Osborne, whom Henrard had visited at his nursery in Fulham in September 1844. 'Blandford Elm', with leaves of the same dimensions, was soon for sale in the USA.
