Spadix (botany)

In botany, a spadix (pronounced /ˈspdɪks/, "SPAY-dicks"; plural spadices /spˈdsz/, "spay-DIE-seez") is a type of spike inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe.

Monoecious aroids have unisexual male and female flowers on the same individual and the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. Typically, the stigmas are no longer receptive when pollen is released which prevents self-fertilization.
