Definition
Meaning
A type of inflorescence, or flower cluster, in which small flowers are densely arranged on a thick, fleshy spike.
In botany, a spadix is a spike with a fleshy axis, typically enclosed by a spathe. The term is also used in zoology to refer to the internal axis of a sea pen or a similar structure in certain corals.
Linguistics
Semantic Notes
The term is almost exclusively used in botanical and, to a lesser extent, zoological contexts. Outside of these fields, it is extremely rare.

- The spadix structure is central to the plant's identification.

Examples
By CEFR Level
- The unusual flower, like that of a peace lily, has a white spathe surrounding a central spadix.
- Botanists note that the spadix, a fleshy spike of densely packed florets, is a defining characteristic of the Araceae family.
- The morphology of the inflorescence, including the ratio of spathe to spadix, is critical for taxonomic classification.

Memory Aids
Mnemonic

FAQ
Frequently Asked Questions
The peace lily (Spathiphyllum) is a common example. Its white 'flower' is actually a spathe surrounding a creamy-white spadix.
Yes, but rarely. In zoology, it can refer to the internal supporting axis of colonial marine animals like sea pens (order Pennatulacea).
Generally, no. While some plants with a spadix (like taro) are cultivated for food, it is typically the tuber or corm that is eaten, not the spadix itself, which may be toxic or unpalatable.
All spadices are a type of spike, but not all spikes are spadices. A spadix is specifically a spike with a thick, fleshy axis and is typically associated with a surrounding spathe.
