Looking at the blossom, we should have thought this 
species had ranked under Amyepatus. But the limits be- 
tween that genus and Prunus are decided by the stone of 
the fruit; the shell of this in the first genus is punctured at 
the outer surface by numerous small holes, nearly as fine, as 
pores; a feature which is not found in the latter, the shell: 
of which is distinguished by the prominent sutures of the 
margin. And those who have had the opportunity of ex- 
amining the fruit of our plant, have found it to belong to 
Pronvs.
