 Bisexual, perfectBisexual flower with both functional pistils and stamens
Sexual system
 MonomorphicOne kind of plant (floral morph) in the population
  HermaphroditeMost commonly applied to plants with bisexual flowers, but all monomorphic populations consist of hermaphrodite individuals
  MonoeciousPistillate and staminate flowers on same plant
  GynomoneciousBoth bisexual and pistillate flowers on same plant
  AndromonoeciousBoth bisexual and staminate flowers on same plant
  TrimoneciousBisexual, pistillate, and staminate flowers on same plant
 DimorphicTwo kinds of plants (floral morphs) in the population
  DioeciousOne morph male (with staminate flowers only); the other female (with pistillate flowers only)
  GynodioeciousOne morph female, the other hermaphrodite (with either bisexual flowers or both pistillate and staminate flowers)
  AndrodioeciousOne morph male, the other hermaphrodite (as above)
 TrimorphicThree floral morphs in the population
  TrioeciousMales, females, and hermaphrodites
