The Buck's-eye Chesnut of the Ohio has always been a 

 doubtful plant. 



Michaux who first noticed it says that he never found it 

 in the Atlantic part of the United States, but only beyond 

 the mountains, especially on the banks of the Ohio, between 

 Pittsburgh and Marietta, where it is extremely common, and 

 called Buck's-eye ; but, he adds, is not to be confounded 

 with the plant called by that name in Virginia and North 

 Carolina, which is Pavia lutea. The ordinary height of the 

 tree is described by Michaux to be not more than from 10 

 to 20 feet, but he found specimens as much as 35 feet high. 

 Its flowers were unknown to him ; he states the fruit to be 

 spiny, and about half the size of that of the common Horse- 

 chesnut, the bark of the old trunk to be blackish, and the 

 liber to have a strong disagreeable odour. 



M. DeCandolle adds nothing to Michaux's account, and 

 Mr. Loudon regards this plant as a mere variety of iEsculus 

 Hippocastanum. In the latter opinion I do not coincide. 

 In addition to Michaux's account of the plant, and the im- 

 probability that a species found wild only on the Ohio, and 

 confined to a limited region, should be the same with a native
