Solution
The correct option is A Descending imbricate
In the family Papilionaceae, the Corolla has a shape of a butterfly due to the varying size of the petals. There are five petals in the corolla. The posterior-most is the large petal called standard or vexillum. It overlaps the lateral petals called the wings. The wings then overlap the innermost fused petals called keel or carina. The overlapping is seen in the descending order of the size. This type of arrangement is called vexillary or descending imbricate.Hence, the correct answer is 'Descending imbricate'.
