Detailed explanation-1: -Vexillary or descending imbricate aestivation is a characteristic of family fabaceae. In it, the posterior largest petal (standard) overlaps two lateral petals (wings) which in turn overlap two anterior petals (keel). It is also called pailionaceous corolla.
Detailed explanation-2: -Stem: Erect or climber; Fabaceae includes shrubs, herbs, trees and majorly climbers. Leaves: Petiolate, pinnately compound or simple; pulvinus leaf base, stipulate; reticulate venation.
Detailed explanation-3: -Vexillary aestivation is a distinctive arrangement in which one giant petal covers the other smaller petals. The vexillum is the bigger petal, while the wings are the two bent petals that are laterally positioned. The two innermost, boat-shaped petals are known as keels in this location. Example: Bean flower.
Detailed explanation-4: -Flowers of Fabaceae do not show actinomorphic nature, twisted aestivation and gamopetaly.
Detailed explanation-5: -Valvate aestivation is common to all three families Fabaceae, Solanaceae and Liliaceae families.
