Most certain plant ID's?

[Koen G]

Some test against historical practice and traditions would be welcome, though I'm not sure what it should look like. The comparison to the battlements isn't entirely fair: with the battlements, we have one positively identifiable item. We identify the item (swallowtail battlements) and check where it occurs. But when it comes to the plants, we would make an assumption about the nature and purpose of the VM plant collection, and then compare them to other known collections. But how can this help us when the VM does not overlap that much with known traditions, and we can only guess as to its purpose?
