Answer 1

Answer:

In pea and bean flowers, there are five petals, the largest overlaps the two lateral petals which in turn overlaps the two smallest anterior petals. This is called Vexillary or papilionaceous aestivation.

Answer 2

The largest petals overlap the lateral ones in the papilionaceous aestivation.

Explanation: In papilionaceous aestivation, the largest petal overlaps the two lateral petals.

• There are five petals in the papilionaceous corolla that is found in the family Papilionaceae.
• The largest petal of papilionaceous aestivation is known as standard or vexillum and the two lateral petals are known as wings.
• The vexillum overlaps the wings which in turn overlaps the keels.
• Keels are the two smallest anterior petals of the papilionaceous aestivation.
