A number of them show signs of having been drawn from flattened specimens. I think there's a pretty high probability that viola and knapweed were drawn from specimens, considering the way the leaves are facing the viewer on viola, and are flattened together on the knapweed.
I don't know if they all were, but some show signs of it.
