Question

In which type of aestivation the petal arrangement is 2 external, 2 internal and 1 partly external and partly internal?

• A. Twisted
• B. Imbricate
• C. Quincuncial
• D. Valvate

Answer 1

Answer: (C)

Quincuncial

Quincuncial is a modification of the imbricate type of aestivation. Out of the five petals, two are completely internal, two completely external and in the remaining petal, one margin i.e., one part petal is internal and the other margin i.e., another half part of the petal is external.

For example, Murraya and Ranunculus.
Therefore, the correct answer is option C.
