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 four British 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. Dutch Elm Disease accounted for almost completely wiping out the British elm trees during the 1970s.
