DECIDUOUS ORNAMENTAL TREES. 15*3 



the Twisted elm (U. c. tortuosa), the trunk of which is 

 singularly marked with hollows and protuberances, and 

 the grain of the wood curiously twisted together : the 

 Kidbrook elm (Z7. c. virens), which is a sub-evergreen : 

 the Gold and Silver striped elms, with variegated leaves, 

 and the Narrow-leaved elm (Z7. c. viminalis), which 

 resembles the birch : the Cork-barked elm {U.c. suherosa), 

 the young branches of which are covered with cork, etc. 



The latter is one of the hardiest and most vigorous 

 of all ornamental trees in this climate. It thrives in 

 almost every soil, and its rich, dark foliage, which hangs 

 late in autumn, and its somewhat picturesque form, 

 should recommend it to every planter. 



The Scotch or Wych elm. (U. inontana) This is a 

 tree of lower stature than the common European elm, 

 its average height being about 40 feet. The leaves are 

 broad, rough, pointed, and the branches extend more 

 horizontally, drooping at the extremities. The bark on 

 the branches is comparatively smooth. It is a grand tree, 

 " the head is so finely massed and yet so well broken as 

 to render it one of the noblest of park trees ; and when 

 it grows wild amid the rocky scenery of its native 

 Scotland, there is no tree which assumes so great or so 

 pleasing a variety of character."* In general appearance, 

 the Scotch elm considerably resembles our White elm, 

 and it is a very rapid grower. Its most ornamental 

 varieties are the Spiry-topped elm {U. m. fastigiata), 

 with singularly twisted leaves, and a very upright growth : 

 the weeping Scotch elm (U. m. pendula), a very 

 remarkable variety, the branches of which droop in a
