Since Aquatic plants are in so many different orders and families, nearly
all of which have many terrestrial members, it seems that aquatic growth
has evolved independently in many different groups.  Molecular studies will
be needed to help resolve many uncertainties within groups, such as witin
the Crypts.  I don't know if there is current research being done.  I
recall that Jan Bastmeijer mentioned Sofiman Othman, who did his thesis on
DNA analysis in Cryptocoryne.  Jan said that he is now at Sains malaysia
(Penang, W. Malaysia.).
