DECIDUOUS ORNAMENTAL TREES. 138 



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 (U. c. virens), which is a sub-evergreen : 

 the Gold and Silver striped elms, with variegated leaves, 

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

 resembles the birch : the Cork-barked elm (U. c. suberosa), 

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



The latter is one of the hardiest and most vigorous

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

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

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

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

 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
