Question

The floral formula belongs to the Family

A. Fabaceae
B. Asteraceae
C. Solanaceae
D. Liliaceae

Answer 1

Floral formulae are the representation of flower structure by using numbers, letters and various other related symbols. It provides for important and substantial information about flowers of a particular species in a compact and lucid form.

Complete answer:
Floral formulae are representations of flower structure which are species specific as well as can be generalized to identify characteristics in the case of certain higher taxa. The floral formulae represent arrangement of the parts of the flower from outside to the inside. The most important symbols used in floral formulae represent floral symmetry, number of sepals, petals, stamens and carpels.
In Solanaceae, the floral formulae represent the flowers are actinomorphic in nature with radial symmetry and are bisexual. The calyx consists of 5 sepals which are connate or gamosepalous (united), and corolla consists of 5 petals that are gamopetalous. The androecium is polyandrous and epipetalous (attached to petals) and consists of 5 stamens. The gynoecium is bicarpellary, syncarpous types. Ovary is superior. It is also known as the potato family.
In Fabaceae, the floral characters show the corolla with five petals, polypetalous, papilionaceous and vexillary aestivation. The flower is complete, bisexual, zygomorphic, hypogynous and bracteate types. Sepals are five which are gamosepalous, with valvate or imbricate aestivation. Androecium with ten stamens (9+1) diadelphous and anthers are dithecous. The ovary is superior, monocarpellary and unilocular.
Asteraceae shows flowers that are sessile, actinomorphic or zygomorphic unisexual. THe calyx is poorly evolved and is present in the form of small scales or bristles. Corolla is 8 and gamopetalous. Stamens are 4-5 and carpels are bicarpellary, syncarpous with stigma binds the ovary inferior.
In Liliaceae, flowers are complete, bisexual actinomorphic and hypogynous. Stamens are 6 arranged in two whorls. Anther is dithecous, introse. Gynoecium is a syncarpous ovary with axile placentation.

Hence, the correct answer is option (C).

Additional information:

Note: The floral formulae are diagrammatic sequences that describe the structure of the flowers. It shows an important way of describing the structures of the flower. It represents the counts of different floral organs. The above floral formulae shows the characteristics of the Solanaceae family.
