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

Options

  1. AThe flower has epipetalous stamens.
  2. BThe petals show contorted aestivation.
  3. CThe flower has epigynous insertion of floral whorls.
  4. DThe flower is actinomorphic.

Correct answer

B. The petals show contorted aestivation.

Step-by-step solution

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.
