In pea, the corolla shows vexillary aestivation where the standard petal overlaps the two wing petals which in turn overlap the two keel petals. In brinjal (Family Solanaceae), the stamens are epipetalous, i.e., they are attached to the petals. In lily (family Liliaceae), the stamens are epiphyllous, meaning they are attached to the perianth. In peach (family Rosaceae), the flower is perigynous, where the ovary is situated in the center and the other floral parts are arranged on the rim of the thalamus forming a cup-shaped structure (hypanthium).
