Ulmus Minor Subsp. Angustifolia
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. Augustine Henry, 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 cu ...

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 ...
