  Pseudo-symmetry \Pseu`do-sym"me*try\, n. [Pseudo- + symmetry.]
     (Crystallog.)
     A kind of symmetry characteristic of certain crystals which
     from twinning, or other causes, come to resemble forms of a
     system other than that to which they belong, as the
     apparently hexagonal prisms of aragonite.
