Ulmus Minor 'Hunnybunii Pseudo-Stricta'
The Field Elm cultivar ''Ulmus minor'' 'Hunnybunii pseudo-Stricta' was originally identified as ''U. nitens'' var. ''Hunnybunii pseudo-Stricta'' Moss by Moss in ''The Cambridge British Flora'' (1914). Moss regarded the tree as a "subvariety" of ''U. nitens'' var. 'Hunnybunii', with a narrower form. Description Moss described 'Hunnybunii pseudo-Stricta' as "differing in the shorter internodes of the young twigs, which tend to remain in one plane, giving the trees a striking appearance". Samara and leaf drawings by E. W. Hunnybun, showing a narrower leaf than 'Hunnybunii', appear in ''The Cambridge British Flora'' (1914). File:Ulmus nitens var. hunnybuni subvar. pseudo-stricta (01).jpg, 'Hunnybunii pseudo-Stricta': flowers and fruit Pests and diseases Though susceptible to Dutch Elm Disease, field elms produce suckers and usually survive in this form in their area of origin.

Ulmus Minor
''Ulmus minor'' Mill., the field elm, is by far the most polymorphic of the European species, although its taxonomy remains a matter of contention. Its natural range is predominantly south European, extending to Asia Minor and Iran; its northern outposts are the Baltic islands of Öland and Gotland, although it may have been introduced by humans. The tree's typical habitat is low-lying forest along the main rivers, growing in association with oak and ash, where it tolerates summer floods as well as droughts.Heybroek, H. M., Goudzwaard, L, Kaljee, H. (2009). ''Iep of olm, karakterboom van de Lage Landen'' (:Elm, a tree with character of the Low Countries). KNNV, Uitgeverij. Current treatment of the species owes much to Richens, who noted (1983) that several varieties of field elm are distinguishable on the European mainland. Of these, he listed the small-leaved ''U. minor'' of France and Spain; the narrow-leaved ''U. minor'' of northern and central Italy; the densely hairy leaved ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Charles Edward Moss
Charles Edward Moss (February 7, 1870 Hyde, Cheshire – November 11, 1930 Johannesburg), was an English-born South African botanist, the youngest son of a nonconformist minister, and is noted for being the editor of the first two parts of ''The Cambridge British Flora'' published in 1914 and 1920. The ''Cambridge British Flora'', under the editorship of Moss, was intended to be a ten-volume survey of the flora of Britain, with contributions by specialists in particular genera. The two volumes that saw publication were of a very high standard, but the project was subsequently abandoned. Early education Moss developed an interest in botany in 1893 when, recovering from a pulmonary abscess, he was advised to go on long outdoor rambles. These took place over the Halifax moors, sometimes in the company of botanists belonging to the Halifax Scientific Society, a society in which he soon became a prominent member. He enrolled as a Queen's Scholar, at Yorkshire College, Leeds in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus Minor 'Hunnybunii'
The Field Elm cultivar ''Ulmus minor'' 'Hunnybunii' was originally identified as ''U. nitens'' var. ''Hunnybunii'' Moss 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 tree was named for C. E. Moss's collaborator, the botanical artist E. W. Hunnybun. Description Moss described 'Hunnybunii' as a taller tree than 'Sowerbyi', with the lower branches spreading at right angles, the upper less tortuous; leaves even more asymmetrical at the base, more acuminate at the apex.Lynch, R I. (1915). Trees of the Cambridge Botanic Garden, in ''Journal of the Royal Horticultural Society'' (Ed.: Chittenden), Vol. 41, part 1, p. 17, 1915. Samara and leaf drawings by E. W.

Samara (fruit)
A samara (, ) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed farther away from the tree than regular seeds would go, and is thus a form of anemochory. In some cases the seed is in the centre of the wing, as in the elms (genus ''Ulmus''), the hoptree (''Ptelea trifoliata''), and the bushwillows (genus ''Combretum''). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus '' Acer'') and ash trees (genus ''Fraxinus''). There are also single-wing samara such as mahogany (genus Swietenia) which have a shape that enables fluttering. Some species that normally produce paired samaras, such as ''Acer pseudoplatanus'', can also produce them in groups of three or four. File:TripleSycamoreS ...

Dutch Elm Disease
Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by elm bark beetles. Although believed to be originally native to Asia, the disease was accidentally introduced into Americas, America, Europe, and New Zealand. In these regions it has devastated native populations of elms that did not have resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Marie Beatrice Schol-Schwarz, Bea Schwarz and Christine Buisman, who both worked with professor Johanna Westerdijk. The disease affects species in the genera ''Ulmus'' and ''Zelkova''; therefore it is not specific to the Ulmus × hollandica, Dutch elm hybrid. Overview Dutch elm disease (DED) is caused by ascomycete microfungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Basal Shoot
Basal shoots, root sprouts, adventitious shoots, and suckers are words for various kinds of shoots that grow from adventitious buds on the base of a tree or shrub, or from adventitious buds on its roots. Shoots that grow from buds on the base of a tree or shrub are called basal shoots; these are distinguished from shoots that grow from adventitious buds on the roots of a tree or shrub, which may be called root sprouts or suckers. A plant that produces root sprouts or runners is described as surculose. Water sprouts produced by adventitious buds may occur on the above-ground stem, branches or both of trees and shrubs. Suckers are shoots arising underground from the roots some distance from the base of a tree or shrub. In botany and ecology In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus Minor 'Stricta'
The field elm cultivar ''Ulmus minor'' 'Stricta', known as Cornish elm, was commonly found in South West England (Cornwall and West Devon), 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.Richens, R. H. (1983). ''Elm''. Cambridge University Press 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.White, J. & More, D. (2002). ''Trees of Britain & Northern Europe''. Cassell's, London. 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, preferre ...

Warriston Cemetery
Warriston Cemetery is a cemetery in Edinburgh. It lies in Warriston, one of the northern suburbs of Edinburgh, Scotland. It was built by the then newly-formed Edinburgh Cemetery Company, and occupies around of land on a slightly sloping site. It contains many tens of thousands of graves, including notable Victorian and Edwardian figures, the most eminent being the physician Sir James Young Simpson. It is located on the north side of the Water of Leith, and has an impressive landscape; partly planned, partly unplanned due to recent neglect. It lies in the Inverleith Conservation Area and is also a designated Local Nature Conservation Site. The cemetery is protected as a Category A listed building. In July 2013 the Friends of Warriston Cemetery was inaugurated to reveal the heritage and to encourage appropriate biodiversity. The address of the cemetery is 40C Warriston Gardens, Edinburgh EH3 5NE. History Designed in 1842 by Edinburgh architect David Cousin, the cemet ...
