Thread for random remarks and questions about Voynich images

Yes, you are certainly right.
One thing to consider is that the plant drawings probably do not all have the same construction mechanism.
Some like the Viola are probably faithfully copied from live or herbarized plant material - or a good herbal.
Most are possibly composites with roots derived from one herbal, stem/leaves from another and flowers invented by the artist.
Others might have been entirely invented by the artist.

So looking at plants as a whole is likely misleading. Especially the flowers. I strongly suggest treating roots/shoots/flowers separately when looking for matches with other sources

Regarding this particular plant, those 'pharma' drawings are very rudimentary. One has to wonder what their purpose (if any) is?
decorative - just to illustrate the text for ornamental purposes
descriptive - a visual description of the text
mnemonic - a help to memorize the plant's properties and uses
?
