The VMS plants are sometimes combined with what are probably mnemonics (mnemonics are found in other medieval plants, as well, such as the "fish root" on the bogbean plant I posted upthread), but I don't think we have any evidence they are combination plants (in the sense of more than one species put together in a single drawing).
I'm not saying the possibility doesn't exist, only that the naturalistic ones (like Viola, Ricinis, Tragopogon, Scamony, Cannabis and several others) do not feel that way, plus... it's a pandora's box. If we move into the realm of combination plants, then anything could be combined with anything (roots, leaves, flowers) and there's no way to know the source plants. Any combination is possible and all of it becomes subjective.
The Plant 2v leaf, for example, can be found on hundreds of different plants if we take only the leaf. There's no way to know where to slice and dice them.
