Ostiole
The apical orifice connecting the cavity of receptacle with exterior. It is the “eye” or opening to the syconium at the bottom of a fig, which is lined with involucral bracts. It is through this opening that the “fig wasp” is able to enter and exit for caprification. It can also be the means through which other harmful insects and water can spoil a fig, especially when the ostioles are larger.
