IPA: /ˈspeɪdɪks/

A thick, fleshy spike that has small flowers and is often covered by a leaf-like structure, commonly found in certain plants like the calla lily.
The spadix of the calla lily is surrounded by a beautiful spathe.
Spadix comes from the Latin 'spadix' (meaning a spike or a flower spike), which is derived from the Greek 'spadix' (σπαδῖξ), meaning a spike or a shoot. The word refers to a type of inflorescence that is characterized by a thick, fleshy spike, often surrounded by a bract.
Think of a 'spike' ('spadix') that holds flowers — that's why spadix refers to a flower spike.
