A water lily flower has six petals, nymphoides has five, but the Voynich MS drawing has four.
Water lily is typically found in herbal manuscripts, but I am not aware of any case where nymphoides is included.

No water lily looks like the Voynich MS drawing, but it looks more than anything like a plain old lily.
Apart from the number of petals.
But that was also draw incorrectly in herbals, as already discussed You are not allowed to view links. Register or Login to view.

This Nymphoides has six, if looked at from the side you might only see the four you think you see...

Or here are 5 and 4 petals

This one is from florida but shows a 5 petaled can look similar to vms plant from the side

This one is N. peltata native to Mediterranean and east Asia, the only temperate example
