Select the incorrect statement for vexillary or papilionaceous aestivation?

Question

Select the incorrect statement for vexillary or papilionaceous aestivation? (A) Two lateral petals are found which are termed as wing. (B) The standard petal is posterior. (C) The largest petal is anterior and overlaps wing. (D) Two smallest anterior petals are known as keel.

Tardigrade Admin · Accepted Answer

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.
Solution

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

Two lateral petals are found which are termed as wing.

The standard petal is posterior.

The largest petal is anterior and overlaps wing.

Two smallest anterior petals are known as keel.

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.

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.
