Native Plants?

Hi.  A week ago I was in Houston with my fiancee & we were hiking around
the local wetlands of Brazos Bend State Park.  I saw what appeared to be
huge specimens of emersed Echinodorus cordifolius growing on the banks! I

Another question: what about collecting wild specimens.  Anyone on the
list do this?  (Not from a State park, but otherwise...)  Is there a
problem introducing parasites or disease into a tank?
