F17r plant: Alkanna Tinctoria?

[MarcoP]

I did try to find some examples of Alkanet in a manuscript in the same presumed time period as the VM but fell short. It would be interesting to see if there are variations in its depiction throughout time.

In European medieval manuscripts, the plant is usually called Buglossa. These three examples are related with the Tractatus De Herbis tradition (from the left: You are not allowed to view links.

The first link also shows a couple of Eastern herbals. You can compare these illustrations with Auslasser's drawing linked by Koen.
