A fruit developed from hypanthodium inflorescence is called

  1. sorosis
  2. syconus
  3. caryopsis
  4. hesperidium

Answer

(2) syconus

Solution

A hypanthodium is a fleshy, cup-shaped receptacle enclosing many unisexual flowers, as in Ficus (fig).

⇒ The multiple fruit that develops from the hypanthodium is called a syconus (syconium), e.g. fig.

∵ Sorosis develops from a spike / spadix (mulberry, pineapple), caryopsis is the simple dry fruit of grasses and hesperidium is the fruit of citrus,

∴ the answer is syconus.
