Among the finest foreign sorts is the Norway maple 

 (A. platanoides), with leaves intermediate in appearance 

 between those of the plane tree and Sugar maple. The 

 bark of the trunk is brown, and rougher in appearance 

 than our maples, and the tree is more loose and spreading 

 in its growth ; it also grows more rapidly, and strongly 

 resembles at a little distance, the button-wood in its young 

 state. Another interesting species is the sycamore tree or 

 Great maple (A. pseudo-platanus). The latter also 

 considerably resembles the plane ; but the leaves, like those 

 of the common maple, are smoother. They are five-lobed, 

 acute in the divisions, and are placed on much longer 

 petioles than those of most of the species. The flowers, 

 strung in clusters like those of the common currant, are 

 greenish in color. It is much esteemed as a shade-tree 

 in Scotland and some parts of the Continent, and grows 

 with vigor, producing a large head, and widely spreading 

 branches.

This is a well-known American tree, found growing 

 wild in all of the states west of the Delaware River. It is 

 a tree of secondary size, attaining generally the height of 

 forty or fifty feet. The leaves are pinnated, bluish-green 

 in color, and are thinly scattered over the branches. The 

 white blossoms appear in June, and are highly fragrant and 

 beautiful ; and from them the Paris perfumers distil an
