#   Petersen has identified this plant with high confidence
#   as 
#
#     Nymphaea alba (white water lily, seerose)
#     http://www.lysator.liu.se/runeberg/nordflor/181.html

#
#   There is indeed a good match in the shape and arrangement of the
#   petals and sepals. Also, the lack of leaves and branches in f7v is
#   plausibly explained by the fact that Nymphaea's flowers float on
#   the water's surface, and thus may have been hidden from the
#   artist's view.
#
#   But if f7v is Nymphaea alba, then what do we make of f2v?
