Vexillary aestivation

Vedclass · Answer

(D) Vexillary aestivation is a characteristic type of aestivation found in the family $Fabaceae$.In this arrangement,the largest posterior petal is known as the standard (or vexillum).It overlaps the two lateral petals,which are called wings (or alae).The wings,in turn,overlap the two smallest anterior petals,which are fused to form the keel (or carina).Examples include pea and bean plants.
