Question

Which of these properties of Cassia is correct?

• A. It has a zygomorphic flower and imbricate aestivation of petals
• B. It has an actinomorphic flower and imbricate aestivation of petals
• C. It has a zygomorphic flower and twisted aestivation of petals
• D. It has an actinomorphic flower and twisted aestivation of petals

Answer 1

Answer: (A)

The flower of Cassia can be divided into two similar halves only in one particular vertical plane. Hence, it is a zygomorphic flower. The margins of petals of Cassia overlap one another but not in any particular direction. Hence, it shows imbricate aestivation.
