Note: Of morphons there are six orders or categories: 1.
      Plastids or elementary organisms. 2. Organs,
      homoplastic or heteroplastic. 3. Antimeres (opposite or
      symmetrical or homotypic parts). 4. Metameres
      (successive or homodynamous parts). 5. Person[ae]
      (shoots or buds of plants, individuals in the narrowest
      sense among the higher animals). 6. Corms (stocks or
      colonies). For orders 2, 3, and 4 the term idorgan has
      been recently substituted. See {Idorgan}.
