The Flower

  • There are four whorls in a typical flower:
  1. Calyx, the unit is sepal
  2. Corolla, the unit is petal
  3. Androecium, the unit is stamen
  4. Gynoecium, the unit is carpel 
  • Some flowers, like lilies, do not have calyx and corolla present separately. Instead there is a single whorl called perianth whose units are called tepals.
  • A flower in which both the androecium and gynoecium are present is called a bisexual flower.
  • A flower in which either androecium or gynoecium is present is called a unisexual flower.
  • Those unisexual flowers that have only androecium are called staminate flowers.
  • Those unisexual flowers that have only gynoecium are called pistillate flowers. 

                                                               

 

 

A flower which has all the four whorls present is called a complete flower.
