• There is a minute thread lies between the 2
    mericarps attached basally to the pedicel
    and apically to the stylopod, it is called
    carpophore.

• The carpophore is the elongation of the
    receptacle between the carpels.

• Each mericarp encloses a single seed
    derived from anatropus ovule.
