Ulmus × hollandica 'Vegeta', sometimes known as the Huntingdon Elm, is an old English hybrid cultivar raised at Brampton, near Huntingdon, by nurserymen Wood & Ingram in 1746, allegedly from seed collected at nearby Hinchingbrooke Park. In Augustine Henry's day, in the later 19th century, the elms in Hinchingbrooke Park were U. nitens. Richens, noting that wych elm is rare in Huntingdonshire, normally flowering four to six weeks later than field elm, pointed out that unusually favourable circumstances would have had to coincide to produce such seed: "It is possible that, some time in the eighteenth century, the threefold requirements of synchronous flowering of the two species, a south-west wind", "and a mild spring permitting the ripening of the samaras, were met."
The field elm cultivar Ulmus minor 'Stricta', known as Cornish elm, was commonly found in South West England, Brittany, and south-west Ireland, until the arrival of Dutch elm disease in the late 1960s. The origin of Cornish elm in England remains a matter of contention. It is commonly assumed to have been introduced from Brittany. It is also considered possible that the tree may have survived the ice ages on lands to the south of Cornwall long since lost to the sea. Henry thought it "probably native in the south of Ireland". Dr Max Coleman of Royal Botanic Garden Edinburgh, arguing in his 2002 paper on British elms that there was no clear distinction between species and subspecies, suggested that known or suspected clones of Ulmus minor, once cultivated and named, should be treated as cultivars, preferred the designation U. minor 'Stricta' to Ulmus minor var. stricta. The DNA of 'Stricta' has been investigated and the cultivar is now known to be a clone.
The hybrid elm cultivar Ulmus × hollandica 'Smithii', commonly known as the Downton Elm, was one of a number of cultivars arising from the crossing of the Wych Elm U. glabra with the Field Elm U. minor. The tree was originally planted at Downton Castle near Ludlow, as one of a batch, not all of them pendulous in habit, raised at Smith's Nursery, Worcester, England, from seeds obtained from a tree in Nottingham in 1810.
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.
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 Field Elm cultivar Ulmus minor 'Hunnybunii' was originally identified as U. nitens var. HunnybuniiMoss by Moss in The Cambridge British Flora (1914). 'Hunnybunii' was reputed to have been commonly planted in the parklands and hedgerows of Essex, Cambridgeshire, and Huntingdonshire before the advent of Dutch elm disease. Melville considered the tree a hybrid of 'Coritana'.
The Field Elm cultivar Ulmus minor 'Sowerbyi', commonly known as the Sowerby Elm, was described by Moss in The Cambridge British Flora (1914). The tree, once referred to as the 'Norfolk Elm' by Smith, was commonly found in the hedgerows and woods of Norfolk, Cambridgeshire, and Huntingdonshire in the early 20th century before the advent of Dutch elm disease. Melville considered it a hybrid of 'Coritana'.
The hybrid cultivar Ulmus × hollandica 'Etrusca' was first mentioned by Nicholson in Kew Hand-List Trees & Shrubs 2: 139. 1896, as U. montana var. etrusca, but without description. The tree at Kew, judged by Henry to be "not distinct enough to deserve a special name", was later identified as of hybrid origin, U. glabra × U. minor 'Plotii', by Melville.
The hybrid elm cultivar Ulmus × hollandica 'Cinerea' was first listed by George Lindley in 1815, as Ulmus cinerea, the ash-coloured elm, and later by the André Leroy Nurseries, Angers, France, in 1856. It was distributed as Ulmus cinerea by the Baudriller nursery, Angers, and as Ulmus montana cinerea by Louis van Houtte of Ghent. A specimen in cultivation at Kew in 1964 was found to be U. × hollandica, but the tree at Wakehurst Place remains listed as U. glabra 'Cinerea'.
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 'Pendula' was said to have been raised in Belgium in 1863. It was listed as Ulmus sativa pendula by C. de Vos in 1887, and by Boom in 1959 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 'Goodyeri', commonly known as 'Goodyer's Elm', was discovered by John Goodyer in 1624 at Pennington near the Hampshire coast between Lymington and Christchurch. No old specimens are known to survive, but the tree is perpetuated by numerous root suckers, notably in the lanes about the Alice Lisle public house in the New Forest hamlet of Rockford. The tree has suffered misidentification in the centuries since its discovery, firstly by Philip Miller in his 'Gardeners' Dictionary' of 1731, and later in the early 20th century by Augustine Henry and Marcus Woodward, who both confused the tree with Plot Elm, whose centre of distribution is in the East Midlands, some 200 miles away and of completely different appearance.
The Field Elm cultivar Ulmus minor 'Coritana' was originally claimed by Melville, while he was searching in the neighbourhood of Leicestershire in 1936 for U. elegantissima, as a new species, which he called U. coritana. He later recorded its distribution in the counties of Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire, Essex, Hertfordshire, Leicestershire, Nottinghamshire, Norfolk, Oxfordshire, Suffolk and Warwickshire. Richens, however, dismissed U. coritana as 'an artificial aggregate' of local forms of Field Elm. Bean noted (1988) that Melville's U. coritana was not recognised in the Flora of the British Isles as a species distinct from U. carpinifolia [:U. minor].
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.
Ulmus × diversifolia, also known as the diverse leaved elm, was originally described by Melville in 1939 as a new species, U. diversifolia, though he later believed it a natural hybrid of Coritanian elm, Plot elm and Wych elm. He recorded its distribution in Hertfordshire, between Hatfield, Hertford and Watton-at-Stone, and in Suffolk, where it was common along the coastal plain from Ipswich and Felixstowe to Lowestoft and Beccles, occurring inland as far as Diss and Debenham, and probably extending further north into Norfolk and south towards Colchester, Essex. He accordingly referred to it as "the East Anglian elm".
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.
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 'Nitida' [:'shining', an allusion to the smooth upper surface of the leaves], the smooth glossy-leaved wych, was described by Fries from specimens collected by P. C. Afzelius in 1841 on the island of Stora Karlsö, Sweden, as Ulmus montana nitida, in Novitiae Florae Suecicae: continuatio, sistens Mantissam III: 20 (1842). The Novitiae Florae Gotlandicae (1844) confirmed U. montana f. nitidaFr. as present on the islands of Stora Karlsö and neighbouring Lilla Karlsö off Gotland, Sweden, but did not report it from Gotland proper. A Stora Karlsö specimen from the Herbarium E. Fries is preserved in the Botanical Museum of Uppsala. The tree was listed by Rehder as U. glabraHuds. f. nitida (1915), a designation adopted by Krüssmann (1984), the latter copying Rehder's 'Norway' provenance error.
The Field Elm cultivar Ulmus minor 'Cretensis' [:from Crete] was first mentioned by Nicholson in Kew Hand-List Trees & Shrubs Vol.2 (1896), as Ulmus campestris var. cretensis, without description. A 1908 herbarium specimen at Kew Gardens with an accompanying description suggests that 'Cretensis' is not synonymous with Ulmus minor var. canescens, also present on Crete.
