ELM

The elm (Ulmus) is a genus of tree of the family Ulmaceae. They have alternate, stalked, deciduous leaves, generally serrated and harsh. There are thirteen species, all natives of the northern temperate zone, four of which are found in Britain, the species including the common elm (Ulmus campestris) once found in southern England, and wych elm (Ulmus montana) formerly found in northern England and Scotland. Small leaved elm (Ulmus minor), also known an the smooth elm, grows in warmer parts of Europe. The elm was once a very common as a timber tree in England; but as it rarely produces seed it is questionable whether it is indigenous. It is a native of the south and middle of Europe, and the west of Asia. Dutch Elm Disease accounted for almost completely wiping out the British elm trees during the 1970s.
