TILIA AMERICANA, L. 155 



Horticultural Value. Useful as an ornamental or street 

 tree ; hardy throughout New England, easily transplanted, 

 and grows rapidly in almost any well-drained soil ; comes into 

 leaf late and drops its foliage in early fall. The European 

 species are more common in nurseries. They are, however, 

 seriously affected by wood borers, while the native tree has 

 few disfiguring insect enemies. Usually propagated from the 

 seed. A horticultural form with weeping branches is some- 

 times cultivated. 



Note. There is so close a resemblance between the lindens 

 that it is difficult to distinguish the American species from 

 each other, or from their European relatives. 



American species sometimes found in cultivation. 



Tilia pubescens, Ait., is distinguished from Americana by its 

 smaller, thinner leaves and densely pubescent shoots. 



TiUa lieterophylla, Vent., is easily recognized by the pale or 

 silver white under-surface of the leaves. 



There are several European species more or less common 

 in cultivation, indiscriminately known in nurseries as Tilia 

 Europcea. They are all easily distinguished from the Ameri- 

 can species by the absence of petal-like scales.
