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 Davey Elm, Ulmus × hollandica 'Daveyi', is an English hybrid cultivar of unknown specific origin, generally restricted to the valleys of Cornwall. Its apparent south-west England provenance, along with its foliage and habit, suggest that it may be a hybrid of Wych Elm and Cornish Elm.
The hybrid elm cultivar Ulmus 'Den Haag' is a Dutch development derived from a chance crossing of the Siberian Elm cultivar Ulmus pumila 'Pinnato-ramosa' and the Belgian Elm Ulmus × hollandica 'Belgica'. S. G. A. Doorenbos (1891-1980), Director of Public Parks in The Hague, finding that seeds he had sown in 1936 from the Zuiderpark 'Pinnato-ramosa' had hybridized with the local 'Belgica', selected six for trials. The best was cloned and grafted on 'Belgica' rootstock as 'Den Haag'; it was planted first in that city, then released to nurseries elsewhere in the Netherlands. The other five were also planted in The Hague.
The Field Elm cultivar Ulmus minor 'Schuurhoek' was originally an old, nameless clone cultivated c.1880 in the vicinity of Goes, Netherlands, which was taken back into cultivation as 'Schuurhoek' by the van't Westeinde nursery at 's-Heer Abtskerke, Zeeland, in the 1950s. It was identified as U. carpinifolia by Fontaine (1968), though treated as a cultivar of U. × hollandica by some authorities.
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 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 elm cultivar Ulmus 'Rubra' was reputedly cloned from a tree found by Vilmorin in a wood near Verrières-le-Buisson in the 1830s. It was listed in the 1869 Catalogue of Simon-Louis, Metz, France, as Ulmus campestris rubra, and by Planchon in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis (1873) as Ulmus libero-rubra: 'Orme à liber rouge' [:elm with red inner bark]. Elwes and Henry (1913) and Bean (1936) listed it as Ulmus montana [:U. glabraHuds.] var. libro-rubro, the former stating that the tree appeared "identical" to Simon-Louis's Ulmus campestris rubra. A specimen in the Zuiderpark, The Hague, was identified in 1940 as a wych elm cultivar, U. glabraHuds.libero rubro.
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.
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 'Viminalis Pulverulenta' (:'powdery'), also known as 'Viminalis Variegata', a variegated form of U. minor 'Viminalis', was first mentioned by Dieck, in 1885 as U. scabra viminalis pulverulentaHort., but without description. Nursery, arboretum, and herbarium specimens confirm that this cultivar was sometimes regarded as synonymous with U. minor 'Viminalis Marginata', first listed in 1864, which is variegated mostly on the leaf margin. It is likely, however, that 'Pulverulenta' was the U. 'Viminalis Variegata', Variegated Twiggy-branched elm, that was listed and described by John Frederick Wood, F.H.S., in The Midland Florist and Suburban Horticulturist 1847 and 1851, pre-dating both Kirchner and Dieck. Wood did not specify the nature of the variegation.
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'.
Ulmus × arbusculaE. Wolf [: "bushy" ] is a putative hybrid of Ulmus scabra and Ulmus pumila raised from seed collected from a large wych elm in the St. Petersburg Botanic Garden in 1902. A similar crossing was cloned ('FL025') by the Istituto per la Protezione delle Piante (IPP), Florence, as part of the Italian elm breeding programme circa 2000.
Alternanthera flavicoma is a species of plant in the family Amaranthaceae. It is endemic to Ecuador.
Asthenotricha flavicoma is a moth in the family Geometridae first described by William Warren in 1899. It is found in the Democratic Republic of the Congo, Cameroon, Uganda and Kenya.
Myrmecia flavicoma is an ant species native to Australia. This species is a member of the genus Myrmecia. It was first described in 1861 by Julius Roger. Myrmecia flavicoma is found in Queensland and some areas of New South Wales.
Ulmus 'Karagatch' is a hybrid cultivar from Turkestan, selected in the early 20th century and considered either a backcrossing of U. × androssowii and U. pumila, or simply a cultivar of × androssowii. It was grown from seeds, introduced from Bairam Ali in Russian Turkestan by Arthur P. Davis in the 1930s, as U. 'Karagatch', under which name it was planted at Kew.
Oedera capensis is a prickly shrublet belonging to the family Asteraceae. It has stems that branch only at the foot and are densely set over their entire length with narrowly triangular leathery leaves with a sharp tip at approximately right angles to the stem. At their tip are what at first sight appears to be a single flowerhead with yellow ray florets and yellow disc florets. In fact, these are mostly nine densely cropped heads, as is suggested by the nine domes of the "disc" of the composite head, the untidy arrangement of the ray florets, and becomes very clear when cutting through the composite head. It is an endemic of the south of the Western Cape province in South Africa.
Oedera imbricata is a prickly shrublet belonging to the family Asteraceae.
Oedera uniflora ("Kalksteenperdekaroo") is a prickly shrublet belonging to the family Asteraceae.
