f18v...Dioscorides...something about those leaves

[Bernd]

Thanks, Koen, I am digging through all the sources!
My preliminary conclusion is that while some Dioscorides plants appear to have influenced the VM, there are barely matches for flowers and roots. Generally VM flowers and roots are more prominent than those in the Dioscorides copies.

I find the blue and red coloration of the inflorescence curious even if the colors are swapped in the VM example. Also the plants both have 3 leaves on each side. The leaf and root shape however doesn't match at all.
