Vexillary Aestivation in Fabaceae Family
Definition of Vexillary Aestivation
Vexillary aestivation is a type of corolla aestivation in which the largest petal, known as the vexillum or banner, is folded over the other petals in the bud. This type of aestivation is found in some families of flowering plants, including the Fabaceae family.
Fabaceae Family
The Fabaceae family, also known as Leguminosae, is a large and diverse family of flowering plants that includes over 19,000 species. This family is found all over the world and includes many economically important plants, such as beans, peas, lentils, and soybeans.
Vexillary Aestivation in Fabaceae Family
The Fabaceae family is characterized by vexillary aestivation, which is a unique feature of the family. In this type of aestivation, the largest petal, known as the vexillum or banner, is folded over the other petals in the bud. This creates a structure that is similar to a butterfly, with the vexillum acting as the wings and the other petals as the body.
Importance of Vexillary Aestivation
Vexillary aestivation is an important characteristic of the Fabaceae family because it helps to protect the reproductive structures of the flower from damage during bud development. The vexillum acts as a shield for the other petals, protecting them from damage from environmental factors such as wind and rain.
Conclusion
In conclusion, vexillary aestivation is a unique feature of the Fabaceae family that helps to protect the reproductive structures of the flower during bud development. This family includes many economically important plants and is found all over the world.

In flowering plants, placentation occurs where the ovules are attached inside the ovary. An example of axile placentation is Lemon. In this type of placentation the ovary is sectioned by radial spokes with placentas in separate locules.

Pentamerous, actinomorphic flowers, bicarpillary ovary with oblique septa, fruit is capsule or berry are the characteristic features of family Solanaceae.
In Brassicaceae – dimerous or tetramerous, actinomorphic but sometimes zygomorphic flower, bicarpellary ovary with a false septum (called replum), fruit is siliqua or silicula.
Lilicaeae – Trimerous, actinomorphic flower, tricarpillary, syncarpous ovary, fruit is berry or capsula.
Asteraceae – Pentamerous, actinomorphic or zygomorphic flower, bicarpillary, syncarpous, unilocular ovary, fruit is cypsella.

EduRev NEET answered |
If the gynoecium is situated in the center and other parts of the flower are located on the rim of the thalamus almost at the same level, it is called perigynous.
Both diagrams show the perigynous condition.
