Mimosa pudica. Almost all features of this plant match the description. Here is a picture of Mimose Pudica:

Two sets of leaves (large and clustered, as well as small and diverse) appear on the folio. The small bulbs that are characteristic of Mimosa Pudica also appear. The large flower on top, while not perfectly accurate, is also depicted.
A peculiarity of this plant is that if you touch it, it's larger leaves will automatically fold downwards and inwards. I believe this is eactly what is being shown in folio f19r. Here is a depiction of the plant's repsonse to touch:

It is called "touch me not", because if you touch it, it will respond defensively using an electric inner reaction.
Could the striking ressemblance to the VM be merely coincidental? Maybe. The only issue is that this plant is native to South America
only.
