sides, hairy on the edge, the notch in the margin closed or 

 partially closed by the two incurved points. 



Horticultural Value. Hardy throughout New England ; 

 grows in any soil, but prefers a deep, rich loam ; the ideal 

 street tree with its high, overarching branches and moderate 

 shade ; grows rapidly, throws out few low branches, bears prun- 

 ing well ; now so seriously affected by numerous insect enemies 

 that it is not planted as freely as heretofore ; objectionable 

 on the borders of gardens or mowing land, as the roots run 

 along near the surface for a great distance. Very largely 

 grown in nurseries, usually from seed, sometimes from small 

 collected plants. Though so. extremely variable in outline, 

 there are no important horticultural forms in cultivation.
