Class V. Order IL 67 



This stately tree is distinguished at sight from the cultivat- 

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

 its 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. 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 principally 

 used to form the naves or hubbs of wheels.
