Q. Select the incorrect statement for vexillary or papilionaceous aestivation?

NTA AbhyasNTA Abhyas 2020Morphology of Flowering Plants

Solution:

In vexillary aestivation the largest posterior petal is called as standard or vexillum, two lateral petals are called wings and the two anterior smallest petals which are fused are known as keel. Vexillary aestivation thus shows a $1+2+\left(2\right)$ arrangement of petals.
