(A) Inverted pairs mutant type (Pe,Se, Car,St), obtained reversing the potential . Carpels in red, stamens in orange, petals in light green and sepals in light blue. The undifferentiated cells are in dark blue. (B) Photograph of the flower of Lacandonia schismatica. Note that in the perianth of this flowering species sepals and petals are not distinguished, and it has six so-called tepals, yet its reproductive organs are inverted, as those of the simulated mutant.
