Question

Which of the family shows epigynous condition?
A. Compositae
B. Liliaceae
C. Solanaceae
D. Malvaceae

Answer 1

Hint: The position of the ovary of a flower determines the different flower types. Based upon this, there are three main categories known as: hypogynous, perigynous, and epigynous. If the sepals, petals and stamens in a flower arise from the top of the ovary, or from a hypanthium inserted above the ovary, they are known as epigynous. Ovary of an epigynous flower is inferior. Daffodil is an example of an epigynous condition.

Complete answer:
Option A Compositae: Compositae, also known as Asteraceae, the aster, daisy, or composite family of the flowering plant order Asterales. One of the largest plant families is the Asteraceae. The members of the asteraceae family have flower heads which are composed of many small flowers known as florets and are surrounded by bracts or leaf-like structures. The Compositae family shows an epigynous condition, in which sepals, petals and stamen arise from the top of the ovary.
Hence option A is the correct answer.
Option B Liliaceae: The Liliaceae family are monocotyledonous, perennial, herbaceous, bulbous flowering plants with contractile roots and simple root hairs. The Liliaceae family has superior ovaries, which means they are hypogynous. They are syncarpous, along with three fused carpels and are either trilocular or unilocular.
Hence option B is not correct.
Option C Solanaceae: Solanaceae, which are also known as nightshades, are the family of flowering plants which ranges from annual and perennial herbs to vines, epiphytes, lianas, trees and shrubs. The Solanaceae family also includes a number of agricultural crops, spices, medicinal plants, weeds, and ornamental plants. They also have a superior ovary and are hypogynous.
Hence option C is not correct.
Option D Malvaceae: The malvaceae are a family of herbs, shrubs, and trees of the order Malvales. These are characterized by Monadelphous stamens and one-celled anthers. Okra, cotton, cacao and durian are the well-known members of this family. The malvaceae family also shows superior ovaries and are hypogynous.
Hence option D is not correct.

Hence, Option A Compositae is the correct answer.

Note:
The floral parts in an epigynous flower such as the petals and stamens are attached to or near the upper part of the ovary. While other parts are superior, the epigynous flower has an inferior ovary. Attached to the top of the ovary is the androperianth. Style and stigma only are visible from outside. The thalamus is fused with the wall of the ovary which is usually flask shaped.
