key. In the mountain maple they are reddish and the wings 

 are not spreading while in the striped maple the wings are 

 widely spreading and bright green. 



The mountain maple is common from northern New York 

 to Georgia and westward. In the Hudson Valley it is very 

 common from the Highlands northward. It is too small to 

 be of economic importance. 



Silver Maple Acer saccharinum 



This is one of the most beautiful and widely planted 

 maples used for ornamental purposes. It frequently attains 

 a height of 120 feet and a trunk diameter of 3 feet. On 

 the old trunks the bark is split into thin scales but the 

 young branches are clothed with a smooth bark. 



The leaf-blade is roundish in general outline, but is deeply 

 5-lobed to beyond the middle. They are bright green on 

 the upper side, whitish or gray beneath. Long before the 

 leaves appear the tree is covered with its flowers. They are 

 greenish-red, but have no petals. Each individual flower- 

 stalk is so short that the flowers appear to be stalkless and 

 attached several together along the sides of the twigs. The 

 typical " key " fruits have widely diverging wings. 



The silver maple grows plentifully from New Brunswick 

 to Florida and westward. It is common throughout the 

 Hudson Valley. The brittleness of its wood has limited its 

 use in the arts and manufactures. 



Red Maple Acer rubrum 



The natural home of the red maple is in swamp lands, and 

 often in the spring, before the foliage appears, the brilliant 

 red flowers give a characteristic ruddy tinge to many of our 

 swamps. The tree is often 120 feet in height and with a 

 trunk 3 feet in diameter. On the old branches and trunk the 

 bark splits off in rough plates; the younger branches are 

 smooth-barked. The 3- or 5-lobed leaves are from 2 to 6 

 inches long and the lobes are more or less sharp-pointed. 

 The silver maple and the red maple are the only tall kinds
