They are one and the same...or so I have been told all my life among them, by ranchers and farmers here in MT and the Dakotas.


Addition:

It is an hour or so later and being bored to death waiting the sub zero temps to lift so I can go hunt pheasants, I googled both buffalo and bull berries. It seems the old ranchers are correct and that they are one and the same. One of those things like goobers and peanuts.
