The Floral Formula of Hibiscus

Hibiscus or China rose is an angiosperm that belongs to the Malvaceae family. It is very widely found in the tropical and subtropical regions of the world and is a cultivated plant.

The Floral Formulas are used to give a description of each plant and its features.

A floral formula is a numerical and symbolic representation of the morphological features of the flower. It depicts the different floral characteristics and structures which make up a flower.

Hibiscus flower floral formula can be written as follows-


Br Brl ⊕ ⚥ K(5) C5 A(∞) G(5)


Every symbol and number in the floral formula has a specific meaning and characteristics to it. Br symbolizes that the hibiscus is a bracteate flower. Brl symbolizes that the hibiscus is also a bracteolate flower. ⊕ symbolizes that hibiscus is an Actinomorphic flower. Actinomorphic flowers are those flowers that have radial symmetry in them. ⚥ symbolizes the fact that the china rose is a bisexual flower having both androecium and gynoecium. In K(5), K stands for the calyx whorl of flowers. The number 5 symbolizes that there are five sepals in the calyx whorl. The brackets here represent the gamosepalous condition. This means all the sepals are fused into a tube-like structure. C5 symbolizes the corolla whorl with five free petals in a polypetalous state. A(∞) represents the androecium whorl of the flower. There are an infinite number of stamens in the hibiscus fused into a single tube (monadelphous condition) which is attached to the petals (epipetalous). The attaching line from C5 to A(∞) shows the epipetalous condition. G(5) represents the gynoecium whorl of the flower with 5 representing 5 fused carpels. The line below G represents superior ovary or hypogynous condition.


The floral formula for the hibiscus is very helpful in depicting the floral morphological characters of the flower. The floral formula of China rose along with the floral diagram is important from the perspective of the NEET examination.
