If you look at the snaky root, you will see it has eyes. I think it probably does represent a snake and is probably one of the plants with viperina or serpentina in the name (bistort is one of the possibilities).
The similarity in the leaves to the knapweed (I think it's probably brown knapweed based on the shape) might be coincidental. There are many plants with leaves like this, especially if the plant has been dried (which pushes the leaves together in a clump), so it's hard to know if there's any connection between the knapweed plant and the one with the snake root.
I don't know if others have suggested teasel for the plant on the right, but it has always looked like teasel to me (as we discussed on the earlier thread), and I still think the thick messy root is a representation of raw, uncarded wool. I honestly believe that's why it was drawn that way.
