The whole of the American oaks 

 belonging to the section Phellos are re- 

 markable for retaining their leaves, in 

 particular soils and situations, for two, 

 three, and in some cases even four, years, without their changing colour ; 

 differing in this respect, both from evergreens, which change their leaves in 

 the spring of every year ; and from those de- 

 ciduous trees which retain their leaves in a 

 withered state during winter.
