Answer:
Pea
Pea shows the following characteristics:-
Zygomorphic or Bilateral - the flower is divided into two equal halves only in one vertical plane.
Vexillary or Descending imbricate aestivation - the anterior petal is innermost and posterior petal is outermost and largest.
Diadelphous- when the filaments are united in two bundles but the anther remains free.
Marginal - found in unilocular ovary. The placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge
So, the correct answer is 'Pea'
