The reason for the choice is that it is the second of the two plants out of my "focal set" with high consensus in identification between various researchers (the other being f5r, where the consensus nevertheless might have been misleading, as we discussed in the respective thread).
Th. Petersen, E. Sherwood and Steve D all consider You are not allowed to view links. Register or Login to view. as thistle (cirsium oleraceum), while the Finnish biologist just does not provide identification of that plant.
So is it thistle or there are better matches?
Thistle?
Thistle usually has pinnatisect, alternate leaves and most do not merge at the stem like the VMS plant. The calyx tends to be thorny more than smooth-scaly.
Some of the
Centaureas match the scaly calyx, but their leaves do not match well at all. I suppose it might be an original way of representing
Centaurea vulgaris, which has opposite leaves and a scaly calyx, but the stems don't branch and the leaves aren't hairy or spiny.
Rhodanthe has the right parts in the right places, but the flowers are too fluffy and the leaves too skinny to match 54r.
In old herbals,
Carduus benedicta was occasionally (and incorrectly) shown with opposite leaves, but it doesn't really resemble the VMS plant in other ways and the VMS illustrator usually correctly depicts alternate/opposite so I highly doubt it's
C. benedicta (which is the thistle most often shown in old herbals).
Also, I suspect from the way 54r is drawn that these leaves are woolly rather than spiny. Thistle leaves are much more serrated. It doesn't look like most of the thistles, except superficially.
I'm not absolutely certain of the ID for 54r, I'm still keeping my eyes open... I have a few thoughts, but they are tentative...
Cerastium tomentosum has woolly leaves that clasp the stem and white flowers but... the flower head isn't scaly.
The leaves of
Stachys byzantina,
Stachys lanata, and
Marrubium are woolly and opposite, but they don't clasp the stem and the flowers are not a good match. The same with
Veronica (speedwell), Ziziphora,
Hypericum pubescens, and
Cerastium, closer match for the leaves but not the flowers.
Silene has opposite hairy leaves and white flowers, but no scales.
So none of those really shout out, "Me! Me!"...
I will accept
Cirsium oleraceum as a possibility. The leaves are opposite and spiny and clasp the stem and it does have a scaly calyx but the flowers are quite a bit thicker than 54r, so I'm not 100% sure.
Another possibility might be
Origanum dictamnus. It's in many of the old herbals, it's both a medicinal plant and a spice, it has woolly, opposite leaves that sometimes meet at the stem, and it has a "scaly" flower head with little florets that stick out at the end. The only reason I'm not completely convinced it's 54r is because
the O. dictamnus flower has very distinctive open scales and the VMS plant has flattened scales, so I'm reluctant to call it an ID. It is, however, a better match than most of the thistles, with the exception of
Cirsium oleraceum (cabbage thistle), which matches quite well.
So why am I so uncertain? Because the VMS leaves are ambiguous. Are they woolly or spiny? If they are woolly, it's not thistle. If they are spiny, it might be
Cirsium oleraceum.
