TREES OF UPRIGHT HABIT 



pyramidal in outline and not so striking in appear- 

 ance as the two already described. Of the many 

 species of Maple native of the Old World only the 

 Norway Maple has sported into an upright form. 

 It is known as Acer platanoides var. columnar e but is 

 really pyramidal in habit. 



A very distinct tree is Liriodendron Tulipifera var. 

 pyramidale, the fastigiate Tulip-tree. This originated 

 in the nursery of Simon Louis, near Metz, Alsace, 

 and has been grown in the Arnold Arboretum since 

 1888. It has the familiar, large leaves of the type 

 but the branches are quite upright. Like the parent 

 it is not attacked by pests of any sort and it deserves 

 to be widely known. 



One of the narrowest of trees is Ulmus glabra var. 

 fastigiata, the Exeter Elm, a form of the Scotch Elm 

 which originated in a nursery in Exeter, Devonshire, 

 nearly a century ago. Truth to tell it is a rather 

 ugly tree of little merit save that it is curious. On 

 the other hand, the Cornish Elm (U. nitens var. 

 stricta) is beautiful. This is the common Elm in 

 Cornwall and parts of Devonshire, and at its 

 best is a tree 80 feet tall and 15 feet in girth of 

 trunk. The lower branches curve outward and 

 upward while the upper ones are short and ascend- 

 ing, and the symmetry of the tree is graceful and 

 pleasing. Very similar in habit is the Guernsey Elm
