What is special about Voynich plants?

[JoJo_Jost]

Since some parts of the plants match known plants perfectly, while others—such as the roots—do not, I could imagine, that the plants are also “coded”—in that at least the roots have been swapped according to a certain logic, and perhaps the flowers, leaves, and stems as well.

So, at least shifted by one or something like that.

But I admit that this is nothing more than a completely unprovable idea...
