I'd add hemlock in there in too. Both are plants you'll see in parks in town. A toddler died here a few years ago because his parent allowed him to play in the big plants with the pretty white flowers. They don't look dangerous and don't have to be eaten to be deadly. Breathing too much pollen is enough, especially for a child.

I'm pretty confident with berries as I've got plenty of experience, but I don't mess with wild carrot or even elderberry as I don't feel I have the knowledge at this point to make it worth the risk. There are just too many lookalikes.

And, other nightshades such as tomatoes, bell peppers, and goji berries contain lectins.
