Spadix


Spadix

In botany, a spadix (pl. "spadices") is a type of spike: an inflorescence with small flowers crowded on a thickened, fleshy axis. The term is applied to certain monocotyledons, especially members of the Family Araceae called arums or aroids. In these flower heads there is typically also a spathe (from Ancient Greek "spathe" "broad blade") present: a large, usually showy and solitary, bract that either subtends (lies just below) or partially encloses the spadix. The "flower" of the anthurium is a typical spadix with a large colorful spathe.

In monoecious aroids (possessing separate male and female flowers, but with both flowers present on one plant), the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. In aroids with perfect flowers the stigma is no longer receptive when the pollen is released, thus preventing self-fertilization. There are also some dioecious species.
