Constituents of the floral formula of hibiscus
The floral formula of hibiscus is written in the form as follows- Br Brl ⊕ ⚥ K(5) C5 A(∞) G(5). In this formula, every symbol and number has been appointed a specific meaning and characteristics to it.
For example,
Br symbolises that the hibiscus is a bracteate flower, and Brl also symbolises that the hibiscus is also a bracteate flower.
⊕ this sign symbolises that hibiscus is an Actinomorphic flower.Actinomorphic flowers are those flowers that consist of radial symmetry in them.
⚥ symbolizes the fact that the china rose is a bisexual flower having both androecium and gynoecium.
K(5), K stands as a term for the calyx whorl of flowers. The total number of five sepals in the calyx whorl symbolises K in K(5). The gamosepalous condition is represented by the brackets given here. This bracket means that all the sepals are now fused into a tube-like structure,
C5 symbolises the corolla whorl consists of five free petals in a state known as polypetalous.
A(∞) represents the androecium whorl of the flower.
Conclusion
There are a huge number of stamens present in the hibiscus fused into a single tube (monadelphous condition) which is attached to the petals (epipetalous). The attaching line from C5 to A(∞) describes the epipetalous condition of the flower. The gynoecium whorl of the flower is represented by G(5) where 5 is representing 5 fused carpels. The line drawn below G represents superior ovary or hypogynous condition. The floral formula of hibiscus is very helpful in depicting the floral morphological characters of the flower.
