A Spadix is a type of inflorescence found in the Araceae family.
It consists of a spathe, which is simply a large leaf-like bract, colourful or showy, to attract pollinators. Spadix is the cylindrical inflorescence, basically a spike, with small flowers on a thickened, fleshy axis and it is protected by the spathe in bud stage.
Many Aroids are ornamental plants due to the Spadix and Spathe.
The sap of Aroids contains needle-like calcium oxalate crystals, which can be mildly toxic and can irritate hands and sensitive tissues. However, not all aroids are toxic and used as vegetable, including their leaves.
Some members of this family reproduce by seeds, whereas many have vegetative propagation.
The inflorescence of species such as Titan arum gives off a very pungent smell, often resembling rotten flesh.
