 Arguing in a 2002 paper that there was no clear distinction between species and subspecies, and suggesting that known or suspected clones of "U. minor", once cultivated and named, should be treated as cultivars, Dr Max Coleman of Royal Botanic Garden Edinburgh preferred the designation "U. minor" 'Sarniensis'.Guernsey Elm was often misnamed 'Cornish Elm' in the UK by the local authorities who planted it extensively.It was sometimes confused in continental Europe with the similar 'Monumentalis'.
