Solution
The correct option is D Caesalpinioideae
Nectaries are the glands that serve to secrete a sugary juice or nectar and are located in the interior of the floral cup, though can be present outside of the flowers also. Nectar attracts the pollinators (mostly insects) and promotes cross-pollination to the flowers.
Brassicaceae or Cruciferae flowers are both self and insect pollinated and are characterized by the presence of nectaries near the base of stamens. Asteraceae or Compositae are typically inset-pollinated and have nectarines which are the multicellular outgrowths of the inferior ovary, surrounding the base of the style.
Papilionaceae flowers are mostly bee pollinated and have nectaries that surround the gynoecium like a sheath and the two lateral petals serve as a platform for insects to sit on.
Caesalpinioideae flowers are wind pollinated and lack nectaries.
Therefore, the correct answer is option D.
