Select the incorrect statement for vexillary or papilionaceous aestivation?
Options
- ATwo lateral petals are found which are termed as wing.
- BThe standard petal is posterior.
- CThe largest petal is anterior and overlaps wing.
- DTwo smallest anterior petals are known as keel.
Correct answer
D. Two smallest anterior petals are known as keel.
Step-by-step 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 + 2 arrangement of petals.
