K5C5A10G2

Significance Of Floral Formula

• Classification: Helps in identifying and classifying plants based on their floral anatomy.

5 sepals

5 petals

Many stamens(counted as one)

1 pistil

The floral formula may be expressed as:

K5C5A∞G1

Conclusion

The floral formula is a very useful device in botany. It helps in studying and grouping flowering plants. Its application enriches our understanding of the variability in plants and their reproductive strategy.
