The Voynich Botanical Plants

Folio 16v, Chrysanthemum plants, are native to Asia and Northeastern Europe. The photograph shown in Figure 16v was taken in Italy and is probably of a cultivated plant. I am showing it because I was struck by how closely it resembles the red flowers in Folio 16v. I have no idea of the identity of the blue flower. Folio 16v could also be ‘red’ yarrow, as shown in this Wikipedia photo.
