 Northern States and southward along the Alleghany 

 Mountains. Its finest growth is on the northern 

 shores of Lake Huron and Lake Superior. 



A slender, somewhat pyramid-shaped, tree, ten to 

 thirty feet high, much and justly prized as one of the 

 best of the native trees for ornamental planting. Its 

 bark and the unripe fruit are very astringent, and are 

 sometimes used medicinally.

 times found in cold swamps and on the borders of streams, 

 along the Northern frontier. 



The cultivated European Mountain Ash or Rowan 

 Tree [P. ancuparia], which is very common in many parts 

 of Europe, and especially in the Highlands of Scotland, 

 differs but slightly from the American Mountain Ash. It 

 varies chiefly in the following items : Leaflets blunter, 

 and rather coarsely double-toothed. Bark rather rough. 

 Fruit larger, oftenest red, but sometimes orange.
