I have the same opinion and experience as Paul. Mine had a waxy covering on
the floating leaves and they were quite orangish in color. The red horemanni
never did produce a floater. I had them get huge like Neil's "trees" also. I
have gotten rid of mine(uruguayensis) but was wondering.........are they
like lilies, having their stomata on the top of the leaf? I should've cut a
leaf off and looked under a scope but never did. I doubt they do but was
wondering about those floaters, not the submersed leaves etc.
