syconium

thumb|right|Cross-section of the syconium of a female creeping fig. The receptacle forms a hollow chamber, its inner wall (white) covered by a shell of [[rufous florets. Their long and curled, white styles occupy the centre. Each floret will produce a fruit and seed. The green, bract-lined ostiole, below, admits wasp pollinators.]]

Syconium (: syconia) is the type of inflorescence which later becomes fruit in figs (genus Ficus), formed by an enlarged, fleshy, hollow receptacle with multiple ovaries on the inside surface. In essence, it is really a fleshy stem with a number of flowers, so it is considered both a multiple and accessory fruit.
