Similar plants in Botany

[Bernd]

Re the following post, i can see the commonalities. The first grouping seems like berries, like strawberry spinach.   
Or it could be like the related Chenopodium species where instead of berries it is just seeds.

The sunflowers have me a bit stumped but the red one might be Celosia of the cockscomb variety. maybe the others are things like carnations, marigolds, or chrysanthemums; big frilly flowers?

Tubeflowers, I think are racemes or corymbs of tiny flowers. I think the central one might be Tanecetum vulgare, despite the blue colouring. I have one about to bloom, the flowers are actually dark right now, and smaller than they will be.

If we really must correlate VM plants to real ones, I think we should stick to those which are attested in contemporary herbals. Some of the plants you proposed are not native to Europe.
Chenopodium/Blitum species bearing red fruit are mostly of American or Asian origin and naturalized in Europe. Blitum virginatum grows in Europe but is rare and not known as medicinal plant from any herbals to my knowledge.
Celosia argentea is native to tropical Africa. The cristate variety arose in cultivation in Asia.

There is no doubt the VM artist was inspired by other herbals, but I do not believe the drawings depict real plants, as they are likely composites. Which plant is it supposed to be if the artist coped flowers from plant A, leaves from plant B and roots from plant C?
