Receptacle (botany)
In biology and botany, the receptacle is the swollen basal part of the flower. It can also be made as the top of the stalk or pedicel. When the stalk of the plant, the part which connects flower to the plant, gets flattened and the other parts of the flower including the 4 whorls (calyx, corolla, androecium, gynoecium) start, that flattened part is called the receptacle. It is the end part of the stalk or pedicel.
