buds are small, lu-own, and smooth, while those of tlu> 

 European elms arc covered with down. The small sulc 

 twigs come out at almost right angles to the larger terminal 

 twigs, which is not the case in other species of elm. 



Other common 

 names: White elm. 



Comparisons : The 

 English elm {Ulmus cam- 

 pestris) is also a tall, 

 dignified tree commonly 

 seen under cultivation 

 in America, but may be 

 told from the American 

 species by the dilTerence 

 in their general contour. 

 The branches of the 

 English species spread 

 out but do not arch like 

 those of the American 

 elm, and the bark of the 

 English elm is darker 

 and coarser. Fig. 38. 

 Little tufts of dead twigs 

 along the main branches 

 and trunk of the tree 

 are characteristic of the 

 English elm and will 

 frequently help to distinguish it from the American elm. 



The Camperdown elm may be recognized readily by its 

 dwarf size and its low drooping umbrella-shaped crown.
