CattleAnnie, did you know there are NO pictures of butterbeans on the internet?
i did find this although i'm not sure if it's true:
Q. I have a recipe for butter beans but I am from Canada and haven't been able to find them. Is there another name for them?
A. There are other names for just about everything, and in this case, butter beans is the other name for lima beans. They can also be called calico beans or Madagascar beans. We know just enough Canadian to suspect that they are called lima beans everywhere other than Quebec
