So the question, then, is how small/lightweight are Pistia seeds?  Orchid 
seeds are like dust, easily carried on the atmosphere.  Are Pistia seeds 
similar?  Alternatively, it may be possible for Pistia to cross the ocean on 
flotsam carried by the Equatorial Current (which runs from Africa to South 
America).  Or, since the cattle egret is known to have crossed the Atlantic 
in recent years, could there have been a bird-assisted dispersal?
