 English elms by its long pendulous branches. It also loses itg 

 leaves in autumn several weeks sooner. The flowers, which 

 appear in April, have commonly from six to eight stamens. 

 They are small, of a dull purple colour, and grow in bunches on 

 slender footstalks. Germs orbicular, compressed. Styles two, 

 recurved, hairy on both sides. The seeds are contained in a flat, 

 oval, winged capsule or samara, which is ciliated at the edge. 

 The leaves grow alternately on opposite sides of the branches ; 

 they are more smooth and more uniformly serrated than those 

 of the English elm. The wood of the elm is tough, and princi- 

 pally used to form the naves or hubbs of wheels.
