Hypogynous flowers are not present in Compositae. In epigynous flowers, the hypanthium is fused to the gynoecium and the free parts of the sepals, petals and stamens appear to be attached to the top of the gynoecium as in Compositae family.

Which of the following options about Compositae family is incorrect?a...
Incorrect Option: Hypogynous Flowers (Option B)

Explanation:
The Compositae family, also known as the Asteraceae family, is one of the largest and most diverse plant families, consisting of more than 23,000 species. This family is characterized by several unique features, but one of the options mentioned is incorrect.

1. Head Inflorescence:
- The Compositae family is known for its unique inflorescence structure called a head, which is composed of several tiny flowers.
- The head inflorescence consists of two types of flowers: ray florets and disc florets.
- Ray florets: These flowers are typically found on the periphery of the head and have a single large petal-like structure called a ligule.
- Disc florets: These flowers are located at the center of the head and have tubular petals.

2. Hypogynous Flowers:
- Hypogynous flowers refer to flowers where the perianth (sepals and petals) and stamens are attached below the ovary.
- This option is incorrect because the Compositae family does not have hypogynous flowers.
- Instead, the flowers in this family are epigynous, meaning the perianth and stamens are attached above the ovary.

3. Syngenesious Anthers:
- Syngenesious anthers are a characteristic feature of the Compositae family.
- In this family, the anthers of the individual disc florets are fused together to form a tube around the style.
- This tube-like structure is called a synandrium and contains multiple anthers.

4. Fruit called 'Cypsela':
- The fruit produced by the Compositae family is called a cypsela.
- Cypselas are dry, one-seeded fruits that do not split open at maturity.
- They are usually small and have a beak-like structure at one end.

In conclusion, the incorrect option among the given choices is "b) Hypogynous flowers." The Compositae family does not have hypogynous flowers; instead, its flowers are epigynous.
