A flower is observed to have vexillary aestivation in its corolla. Which of the following combinations of floral symmetry and placentation is most likely to be found in this flower?

Step-by-step solution

Vexillary aestivation is a characteristic feature of the family Fabaceae (e.g., pea, bean). Flowers belonging to the family Fabaceae exhibit zygomorphic (bilateral) symmetry. Their gynoecium consists of a monocarpellary, unilocular ovary with marginal placentation. Actinomorphic symmetry and axile placentation are typically seen in families like Solanaceae and Liliaceae, which do not show vexillary aestivation. Answer: Zygomorphic symmetry and marginal placentation
