NORWAY MAPLE 



Acer platanoides, Linnaeus 



The Norway Maple is one of the most popular street 

 trees in the United States. There are very few towns 

 and cities in which this tree is not found. It comes to us 

 from Europe, where it is found from Norway to Switzer- 

 land. 



The leaves resem- 

 ble those of the Su- 

 gar Maple, but are 

 deeper green in color 

 and firmer in texture. 

 One characteristic by 

 which it can always 

 be distinguished is 

 the presence of milky 

 sap in the leaf-stalks. 

 If pressed or twisted 

 the leaf-stalks always 

 yield a few drops of 

 milky sap. In early 

 spring the yellowish- 

 green flowers arranged 

 in clusters along the 

 twigs are distinctive. 

 In winter the large, 

 red, blunt - pointed 

 glossy buds are a 

 sure means of identi- 

 fication. In late sum- 

 mer the large fruit 

 keys and wide-spreading wings ripen and may hang on the 

 tree for months. 



The Norway Maple has many merits as a street tree. It 

 is hardy, rather free from disease and insect attacks, retains its 

 leaves longer than the native maples, and endures well the 

 smoke, dust and drought of the city. It has been widely 

 planted throughout New York. 



Another European maple occurs locally in New York. 

 It is the Sycamore Maple (Acer Pseudo-platanus, Linnaeus), 

 It can be distinguished easily by its firm, 3 to 5-lobed leaves 

 with sharply-toothed margins, and its large, blunt-pointed 

 green buds. The fruit keys are smaller than those of the 

 Norway Maple. It does not thrive on all kinds of soil and 

 has not been planted extensively in New York.
