OriginEngland

The Field Elm cultivar Ulmus minor 'Concavaefolia' was briefly described by Loudon in Arboretum et Fruticetum Britannicum (1838), as Ulmus campestris var. concavaefolia. [1] A fuller description followed in Petzold and Kirchner 's Arboretum Muscaviense (1864). [2] Henry noted that Loudon's "insufficiently described" U. campestris var. concavaefolia seemed to be identical with the field elm cultivar 'Webbiana', [3] a view repeated by Krüssmann. [4]

Description

Loudon thought the tree resembled his 'Cucullata' (probably the cultivar later called Ulmus montana cucullataHort.). [5] Petzold and Kirchner in Arboretum Muscaviense (1864) described the leaves of their Ulmus campestris concavaefolia, as short and rounded, dark green above and whitish green below, "more or less concave", that is, curling upwards at the edges so that the pale underside is more prominent than the darker upper (a description, as Henry noted, that matches 'Webbiana'). They noted that the leaves of their var. concavaefolia were smaller than those of their var. cucullata (again, probably Ulmus montana cucullataHort.), but not dissimilar in shape. [6]

Cultivation

If synonymous with 'Webbiana', 'Concavaefolia' is rare but remains in cultivation. No other field elms labelled var. concavaefolia are known, either in herbarium specimens or in cultivation (but see 'Convex-leaved field elms' below).

Synonymy

Convex-leaved field elms

A young, fastigiate, suckering, convex-leaved U. minor cultivar (concave from the underside), stood in the yard of St James's Church, Constitution Street, Leith, till 2017, where an 1882 print showed a narrow elm-like tree, probably the original planting. [7] [8] Its sucker regrowth remains. A second similar convex-leaved suckering field elm stands in East Fettes Avenue, Edinburgh. The leaves of both resemble those of sweet basil, unlike Petzold and Kirchner's var. concavaefolia (probably 'Webbiana').

For a convex-leaved field elm with a more elongated, rather hooded leaf, distributed erroneously by the Späth nursery of Berlin for a short time in the early 20th century as Ulmus racemosa, in cultivation in Brighton and Edinburgh, see 'Cucullata'. No cultivar names are known for convex-leaved field elms.

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.

<i>Ulmus</i> Purpurea Elm cultivar

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.

<i>Ulmus glabra</i> Cornuta Elm cultivar

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.

<i>Ulmus</i> Crispa Elm cultivar

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.

<i>Ulmus minor</i> Propendens Elm cultivar

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.

<i>Ulmus minor</i> Webbiana Elm cultivar

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 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.

The elm cultivar Ulmus 'Hertfordensis Latifolia' was mentioned by Boulger in Gardener's Chronicle II. 12: 298 1879, but without description.

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.

<i>Ulmus</i> Planifolia Elm cultivar

The possible Field Elm cultivar U. minor 'Planifolia' was listed by Loudon in Arboretum et Fruticetum Britannicum (1838) as Ulmus campestris (:minor) var. planifolia, the flat-leaved elm. Green opined that the species was uncertain.

<i>Ulmus</i> Scampstoniensis Elm cultivar

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 glabra 'Australis' is a Wych Elm cultivar described by Loudon in 1838, from a tree in the Royal Horticultural Society garden, as U. montana var. australisHort..

<i>Ulmus</i> × <i>hollandica</i> Fastigiata Elm cultivar

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 Betulaefolia' (:'birch-leaved') is an elm tree of uncertain origin. An U. betulaefolia was listed by Loddiges of Hackney, London, in the catalogue of 1836, an U. campestris var. betulaefolia by Loudon in Arboretum et Fruticetum Britannicum (1838), and an U. betulifoliaBooth by the Lawson nursery of Edinburgh. Henry described an U. campestris var. betulaefolia at Kew in 1913, obtained from Fulham nurseryman Osborne in 1879, as "scarcely different from var. viminalis ". Melville considered the tree so named at Kew a form of his U. × viminalis, while Bean (1988), describing U. 'Betulaefolia', likewise placed it under U. 'Viminalis' as an apparently allied tree. Loudon and Browne had noted that some forms of 'Viminalis' can be mistaken for a variety of birch. An U. campestris betulaefolia was distributed by Hesse's Nurseries, Weener, Germany, in the 1930s.

<i>Ulmus minor</i> Viminalis Elm cultivar

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 'Viminalis Gracilis' [:'slender'] is a form of U. minor 'Viminalis'. Cultivars listed as Ulmus gracilisHort. by Kirchner (1864), and as U. scabra viminalis gracilisHort. by Dieck (1885), were considered by Green to be forms of Melville's U. × viminalis. A 1929 herbarium specimen held at the Hortus Botanicus Leiden is labelled U. campestris var. viminalis f. gracilis, implying a cultivar that differed from the 'type' tree.

<i>Ulmus minor</i> Monumentalis Elm cultivar

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, and described as U. campestris var. monumentalisRinz, 'Pyramid Field Elm', by Kirchner (1864), who said 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.

<i>Ulmus glabra</i> Concavaefolia Elm cultivar

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).
