Receptacle
in botany: (1) Any part which supports another part. The receptacle of a flower is the top of the peduncle on which the flowers are inserted. It may be a flattened area, or a vanishing point, or may be greatly dilated. The receptable of a fruit is its torus. The receptacle of an ovule is the placenta. The receptacle of the sporangia in a fern is the vein passing through their axis. (2) A cavity for the reception of any substance. The receptacle of oil is one of the cysts which contain it, as, for instance, those on the rind of the orange.
