Hi George,

check out work by the Max Plank institute...

Also, just read about a guy who studies the genetics of cattails and
according to him, there can be many variations of cattails in the same
 Interestingly, the more the water is polluted the more he finds genetic
variations. In other words, these plants are so good at cleaning water that
they literally mutate/adapt to meet the exact nature of the water's they are
in !
