The fruit of Rubus species is a cluster of drupelets on top of a conical receptacle.
[1] In the daisy family (Compositae or Asteraceae), small individual flowers are arranged on a round or dome-like structure that is also called receptacle.
They are specialised structures which contain the reproductive organs called conceptacles.
[2] Receptacles also function as a structure that captures food.
