I'm trying to ID this plant and think its a viburnum but with so many varieties, I'm looking for some help in narrowing it down, Thanks in advance, BB Unknown Plant.jpg
Not a viburnum, the alternate leaves exclude that genus. Possibly Frangula caroliniana, but the flowers don't look quite right for that.
Thank you both for your help. The pictures of Frangula (Rhamnus) purshiana on the net look almost exactly like what I've got. I've got some other samples that are becoming diseased so this really helps in diagnosing the disease.
