ornamental tree of 

 graceful habit, conspic-

 large clusters of white 

 flowers in May or June 

 and for its bright red 

 and orange fruit in aut-

Varieties. There are several varieties varying in habit 

 of growth and color of fruit. The following is the most com- 

 monly planted: 



Pyrus aucuparia pendula. Weeping Mountain Ash. 



A form with pendulous, graceful habit. 

 It grows freely, is hardy and is interesting 

 for variety. It is largely used as a lawn 

 curiosity. Propagated by grafting onto the 

 American or European Mountain Ash. 



Pyrus hybrida. 

 Oakleaf Mountain Ash. 



Leaves 5 to 6 inches long, lyrate pinna- 

 tifid, often pinnate at the base, irregularly 

 and sharply serrate, dark green and glab- 

 rous above, pale and densely pubescent be- 

 neath. Flowers white in large conspicuous 

 clusters. Propagated by grafting onto the 

 European or American species. This Moun- 

 tain Ash forms a very pretty lawn or park 

 tree of upright pyramidal habit, attaining a 

 height of 20 or 30 feet. In hardiness it ranks 

 with the European Mountain Ash. It is 

 said to be a hybrid between Pyrus aria 

 (Sweet Seam Tree) and Pyrus aucuparia.
