Ulmus minor subsp. minor Richens, the Smooth-leaved Elm, Narrow-leafed Elm or East Anglian Elm, is a subspecies of the Field Elm native to southern Europe and Asia Minor including Iran. The name Ulmus minor subsp. minor was used by R. H. Richens for Field Elm that was not English Elm, Cornish Elm, Lock Elm or Guernsey Elm. Many publications, however, continue to use plain Ulmus minor for Richens's Ulmus minor subsp. minor. Indeed 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.
