Question

Which of the following conclusions about a flower can't be deduced just by observing the floral formula?

• A. The flower has epipetalous stamens.
• B. The petals show contorted aestivation.
• C. The flower has epigynous insertion of floral whorls.
• D. The flower is actinomorphic.

Answer 1

Answer: (B)

In the floral formula, the epipetalous condition can be denoted by drawing an arc between C and A. The symbol for the actinomorphic flower is a circle with a plus sign within it. It can be seen in the Solanaceae family.
Epigynous insertion of Floral whorls can be depicted by drawing a small segment over G. This also indicates inferior ovary. For observing aestivation a floral diagram is required and a floral formula alone won't be sufficient.
