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.^[1] Many publications, however, continue to use plain Ulmus minor for Richens's subspecies, a name Richens reserved for the undifferentiated continental field elms.^[2] (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.^[3]

In England, narrow-leaved elm is the commonest field elm in East Anglia, the East Midlands, and eastern Kent.^[4][5]
