Ulmus Minor 'Viminalis Stricta'
The Field Elm cultivar ''Ulmus minor'' 'Viminalis Stricta' (:'narrow'), formerly known as ''U. campestris'' var. ''viminalis stricta'', is a fastigiate form of ''Ulmus minor'' 'Viminalis'. A herbarium specimen at Kew labelled ''U. campestris'' var. ''viminalis f. stricta'' was considered by Melville a form of his ''U.'' × ''viminalis''. Description A tree of narrow and "very rigid" growth. A herbarium leaf-specimen shows a leaf resembling that of the type tree, 'Viminalis'. Sheet described as ''U. procera viminalis stricta'' (Kew specimen, 1931) Pests and diseases Trees of the ''U. minor'' 'Viminalis' group are very susceptible to Dutch elm disease. Cultivation No specimens are known to survive. There was a 'Viminals Stricta' at Kew Gardens in the early 20th century. Non-ornamental trees identified as Melville's ''U.'' × ''viminalis'' and matching the form of 'Stricta' occur in East Anglia.Tree determined by Coleman (2000), sample no. 5, as Ulmus × viminalis. plot-el ...

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 ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulmus Minor 'Viminalis'
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 (not ''U. minor'' 'Plotii') 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 listed as ''Ulmus antarctica'' Hort., the 'zierliche Ulme' 'dai ...

Ronald Melville (botanist)
Ronald Melville (12 March 1903 – 6 August 1985) was an English botanist, based at the Royal Botanic Gardens Kew. He is chiefly remembered for his wartime research into rosehips as a source of vitamin C, prompted by the epidemic of scurvy amongst children owing to the reduced importation of fresh fruit. His research concluded that hips from the common Dog Rose, ''Rosa canina,'' held the highest concentration of the vitamin. In later years, he challenged the two-species taxonomy of the British elms proposed by Richens,Richens, R. H. (1984) ''Elm'', Cambridge University Press. identifying five distinct species, several varieties and numerous complex hybrids.Melville, R. (1978). On the discrimination of species in hybrid swarms with special reference to ''Ulmus'' and the nomenclature of ''U. minor'' (Mill.) and ''U. carpinifolia'' (Gled.). ''Taxon'' 27: 345-351, 1978.
