The Shingle Oak has a smooth bark and for three-fourths of its height is laden 

 with branches. It has an uncouth form when bare in winter, but is beautiful in 

 summer when clad in its thick tufted foliage. The leaves are long, lanceolate, 

 entire, and of a shining green. MICHAUX. 



The leaves of Laurel Oak or Shingle Oak are very narrow, almost linear at 

 first with their edges so straightly revolute that they almost touch each other. 

 They are slightly hairy, the ground color yellowish green with a purple tinge. 

 The fresh twigs are flushed with red on the upper side where most exposed to 

 the light. The young leaves stand out stiffly from the ends of the branchlets, 

 studding them with sharply outlined stellate clusters. Being so narrow the 

 foliage is very open a-nd one can see through the tree top in almost any direc- 

 tion so that the tree has an appearance quite distinct from other oaks.
