OF ORNAMENTAL TREES. 205 



Nut large, oblong, ovoid. Eed oak ; Cham- 

 plain oak. 



The trunk and bark of this tree much 

 resemble a chestnut; the branches have a 

 very coarse and rigid appearance, sufficient 

 to distinguish the tree readily even in winter. 

 It makes a pretty object as a single speci- 

 men. It thrives well in very poor soils, but 

 will not do well in low or wet situations. A 

 specimen at Bartram is about sixty feet 

 high and four and a half feet in circumfer- 

 ence. There is a noble specimen a few feet 

 off the boundaries of the Bartram estate; but 

 there is no certainty when it may go to form 

 " post and rails," as I have been informed a 

 solitary specimen of Q. ambigua^ Michaux,, 

 in the vicinity once did. 



20. Q. SESSILIFLORA, Salisbury. Leaves, 

 on long stalks, oblong-ovate, deeply sinuated,, 

 their sinuses acute, lobes obtuse. Fruit clus- 

 tered on very short stalks or sessile. Ses- 

 sile-fruited British oak. 



This is very like the Q. Eobur, and by 



many thought to be but a variety of it. It 



is considered the most ornamental of the two. 



I believe it is not so common as the other,
