To this species are doubtfully referred plums of the Ameri- 
cana group, common on prairies and in thickets and open 
woods. It is usually a shrub suckering freely and forming 
small thickets, producing small red acid fruit with a glaucous 
bloom, Occasionally it becomes a tree of considerable size. 
The true position of the species is still unsettled.
