Ulmus minor subsp. minor
Also called Coritanian Elm, Cornish Elm, Guernsey Elm, Jersey Elm
Ulmus minor subsp. minor, the smooth-leaved or narrow-leaved elm, is a deciduous tree that can reach 35 m and is native to Europe. Growing it is mainly about choosing disease-resistant clones, since Dutch elm disease has badly affected elms.
Ulmus minor subsp. minor, the narrow-leaved elm (also known as smooth-leaved elm or East Anglian elm), was the name used by R. H. Richens (1983) for English field elms that were not English elm, Cornish elm, Lock elm or Guernsey elm. Many publications, however, continue to use plain Ulmus minor for Richens's subspecies, a name Richens reserved for the undifferentiated continental field elms. (Ulmus minor is native to southern Europe and Asia Minor including Iran.) The name Ulmus minor subsp. minor is justified by the existence of at least one other distinctive U. minor subspecies, U. minor subsp. canescens (accepted as such by Plants of the World Online). Dr Max Coleman of Royal Botanic Garden Edinburgh argued in his 2002 paper 'British Elms' that there was no clear distinction between species and subspecies.
Many mature specimens still survive in England, notably in East Anglia. The Woodland Trust currently lists (2013) some 120 surviving "ancient" smooth-leaved elms in England and Wales, some of which are among the elms now being cloned, propagated and planted as part of The Conservation Foundation's 'Great British Elm Experiment' and 'Ulmus londinium' projects, a scheme to identify disease-resistant strains and return elms to city and countryside. Among "varieties with most resistance", Professor Oliver Rackham noted (1986) the 'Boxworth elm', still thriving (2022) in and around Boxworth, Cambridgeshire, and from c.2010 propagated experimentally by the Conservation Foundation.
In a more academically based project, most of the clones of the surviving European field elms that have been tested since the 1990s for innate resistance to Dutch elm disease by national research institutes in the EU, with a view to returning field elm to cultivation in Europe, would be classified by Richens's system as Ulmus minor subsp. minor.
