204 AMERICAN HANDBOOK 



18. Q. ROBUR, Linnaeus. Leaves oblong, 

 somewhat wedge-shaped, smooth and irregu 

 larly sinuate, lobes rounded, acorns cylindri 

 cal. British stalked oak. 



A very valuable kind in ornamental garden 

 ing from the fact of its foliage remaining on 

 green till the frost fairly &quot; drags&quot; it off; while 

 its glossy green summer dress is &quot;highly be 

 coming.&quot; It does not often exceed sixty 

 feet high in its native country, but in America, 

 which is pre-eminently adapted to deciduous 

 trees, it will do much better. The Bartram 

 specimen, growing on thin soil on a rock, is 

 eighty feet high and seven feet in circumfer 

 ence. In general appearance it is allied to 

 our white-oak, but the bark is never scaly, 

 nor are the leaves ever so deeply lobed. It 

 will do well in any situation not too wet. Q. 

 R. purpurea, with fine purple foliage, is a very 

 ornamental variety, of which small specimens 

 are in our vicinity. 



It is propagated by grafting on the com 

 mon kind. 



19. Q. RUBRA, Linnceus. Leaves obtusely 

 sinuated. Cup very flat, with shallow edges.
