I propose this species with some hesitation ; although it ap- 

 pears to be quite distinct fiom any Prunus described by 

 Pursh. The only locality of it, with which I am acquaint- 

 ed, is that given on the authority of Professor D ewey, who 

 informs me that it appeared to be indigenous. There is great 

 obscurity respecting many of the North-American species oi" 

 Prunus, which can only be cleared up by a careful examina- 

 tion of them in a living stale.
