As an American, I have never seen this European species. I was given a book of "Around The World in 80 Trees" by Johnathan Grori for Christmas, and four pages about Elm start by mentioning this tree. It came from southeast Europe and was brought to western Europe and Britain by bronze age farmers or Romans, or both, to provide the wood for supporting grape vines. It usually is sterile and produces lots of sterile seeds to none. It has been propagated by cuttings or by shoots sprouting near the base of the tree. Therefore, this species seems to be of identical clones that result in no real diversity of genetic make-up. Some have classified it as Ulmus minor 'Atinial', and another source thinks it may be a hybrid between the very similar Smoothleaf Elm (U. carpinifolia) x Wych or Scotch Elm (U. glabra), which would make it like an ancient Dutch Elm (U. x hollandica). The Dutch Elm Disease from east Asia in the 1960's & 70's killed off many millions of European Elms, including this one. A few pockets of mature trees of this English Elm survive in England in some isolated locations in the wild. Some survive from strong efforts of hygiene in keeping away the disease. Three American sources showed this tree as having escaped cultivation in the US and southeast Canada in a few areas of several states and provinces, but I don't know how that would possible with it being sterile or so close to sterility. Its leaves are 2 to 3.5 inches long, 2/3rds as wide and looking rather wide, doubly serrate, dark green and smooth or rough above, soft pubescent beneath, with about 12 vein pairs, and a leaf petiole about 1/4 inch long and pubescent. It is a beautiful, large tree like other European Elms, but susceptible to Dutch Elm Disease.
