Zornia glabra is a herb species found in South America and native to French Guiana, Guyana, Suriname and Brazil. [2]
It is well adapted to poor soils with low pH levels. [3]
Ulmus glabra, the wych elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Urals, and from the Arctic Circle south to the mountains of the Peloponnese in Greece; it is also found in Iran. A large deciduous tree, it is essentially a montane species, growing at elevations up to 1,500 m (4,900 ft), preferring sites with moist soils and high humidity. The tree can form pure forests in Scandinavia and occurs as far north as latitude 67°N at Beiarn in Norway. It has been successfully introduced as far north as Tromsø, Norway and Alta, Norway (70°N). It has also been successfully introduced to Narsarsuaq, near the southern tip of Greenland (61°N).
Zornia is a cosmopolitan genus of herbs from the legume family Fabaceae. It was recently assigned to the informal monophyletic Adesmia clade of the Dalbergieae.
The Wych Elm cultivar Ulmus glabra 'Horizontalis', commonly known as the Weeping Wych Elm or Horizontal Elm, was discovered in a Perth nursery circa 1816. The tree was originally identified as 'Pendula' by Loddiges (London), in his catalogue of 1836, a name adopted by Loudon two years later in Arboretum et Fruticetum Britannicum, 3: 1398, 1838, but later sunk as a synonym for 'Horizontalis'.
The Wych Elm cultivar Ulmus glabra 'Corylifolia' was first described by Host in Flora Austriaca (1827). Another cultivar of the same name is described by Zapalowicz, in Conspectus Florae Galiciae Criticus (1908), but was assumed to be 'Cornuta'.
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 putative Wych Elm cultivar Ulmus glabra 'Fastigiata Macrophylla' was first mentioned by Dieck in the Zöschen catalogue in 1885 as Ulmus montana forma fastigiata macrophylla, without description. Hartwig added a description in 1892. Berndt received "from a renowned nursery in Holstein" an Ulmus montana fastigiata macrophylla, possibly the same clone, in 1903, which he listed and described as Ulmus glabra fastigiata in Graf von Schwerin's Mitteilungen der Deutschen Dendrologischen Gesellschaft (1915).
The Wych Elm cultivar Ulmus glabra 'Firma' was described by Schneider in 1904.
The cultivar Ulmus glabra 'Insularis' [:'island'], the Ven island elm, a fastigiate form of Wych Elm from Sweden, was identified and described by Nilsson in Lustgården 30: 127. 1949, as U. glabraHuds. f. insularis. Nilsson considered it "closely related to subspecies montana(Stokes) Lindqvist". The cultivar arose from a tree on Ven island in Öresund sound, planted c.1900 between Haken and Husvik, possibly from self-sown local seedlings, and approaching 2 m in girth by the late 1940s.
The Wych elm cultivar Ulmus glabra 'Latifolia Aureo-Variegata' was first mentioned by Neubert in Deutsches Magazin für Garten- und Blumenkunde 1871 as Ulmus campestrisL.latifolia aureo-variegata.
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 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 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.
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..
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 elm cultivar Ulmus 'Fastigiata Glabra' was distributed by the Späth nursery, Berlin, in the 1890s and early 1900s as U. montana fastigiata glabra. Späth used U. montana both for cultivars of wych elm and for those of some U. × hollandica hybrids like 'Dampieri'. A specimen of U. montana fastigiata glabra in the Royal Botanic Garden Edinburgh was determined by Melville in 1958 as a hybrid of the U. × hollandica group.
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).
Protea glabra, also called the Clanwilliam sugarbush, is a flowering shrub belonging to the genus Protea.
Zornia glochidiata is a leguminous herb of the Fabaceae family, it is widely distributed in the Sahel regions of West Africa. It is reputed to be an important forage plant in the region.
