Floral Formula of Asteraceae
The floral formula is a conventional way of recording a flower’s structure using capital letters to identify parts and numbers to indicate the number of components in each part. The floral formula for Asteraceae is:
Kx Co(5) S or 0 P or 0
- K: Represents the calyx, usually indicated by “K” for sepals, and “x” denotes that the calyx is represented by multiple sepals, which may vary in number across different species.
- Co(5): Indicates the corolla, where “Co” stands for petals, and “(5)” represents the number of petals. In Asteraceae, the petals are fused together to form a tubular structure.
- C: Represents the androecium, which refers to the collective term for the stamens or male reproductive organs.
- 0: Indicates that there are no distinct petals or sepals in Asteraceae flowers.
- P: Represents the gynoecium, which refers to the collective term for the pistils or female reproductive organs.
- 0: Indicates that there are no distinct petals or sepals in Asteraceae flowers.
Asteraceae – Angiosperm Family
Asteraceae, commonly known as the aster, daisy, or sunflower family, is one of the largest plant families characterized by composite flower heads and alternate leaves. It includes a wide variety of economically important plants, such as sunflowers, daisies, and dandelions. Members of this family are used for food (lettuce, artichokes), medicine (chamomile, arnica), and ornamental purposes. Their ecological importance lies in providing nectar and habitat for pollinators, contributing to biodiversity and ecosystem health.
