The Flower
- The thalamus gives rise to the floral appendages.
- The floral appendages are present in the form of whorls (grouped and arranged in a circle).
- There are four whorls in a typical flower:
- Calyx, the unit is sepal
- Corolla, the unit is petal
- Androecium, the unit is stamen
- Gynoecium, the unit is carpel
- A flower that has all four whorls present is called a complete flower.
- A flower in which any one or more whorls are absent is called an incomplete flower.
- 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.
Petals form the whorl called the corolla.
