SYLVA AMERICANA. 



Over-Cup White Oak. Quercus macrocarpa. 



This interesting species is 

 most multiplied beyond the 

 Alleghanies, in the fertile 

 districts of Kentucky and 

 West Tennessee, and in 

 Upper Louisiana near the 

 Missouri. It is called by 

 the Americans Bar Oak 

 and Over- Cup White Oak, 

 and by the French of Illinois, 

 Chene a gros gland. 



This is a beautiful tree, 

 more than GO feet in height, 

 laden with a dark, tufted 

 foliage. The leaves are 

 larger than those of any 

 other oak in the United 

 States, being frequently fifteen inches long and eight broad : they 

 are notched near the summit, and deeply laciniated below. It 

 fructifies annuallv and flowers in May. The acorns, which are 

 also larger than those of any other American species, are oval and 

 inclosed for two-thirds of their length in a thick, rugged cup, 

 bordered with fine, flexible filaments. Sometimes, however, in 

 compact forests, or in very temperate seasons, the filaments do not 

 appear, and the edge of the cup is smooth and bent inwards. 



The fructification of this tree is not abundant, and as its wood 

 is inferior to that of the w T hite oak, it is little esteemed in the 

 United Sttates.
