Spathes and spadices are terms used in botany to describe specific parts of certain plant structures, particularly in the Araceae family, which includes plants like the arum, calla lily, and elephant ear. A spath, also known as a spathe, is a large, often colorful, and leaf-like structure that surrounds and protects the spadix. It typically has a distinctive shape and is often used for pollination and attracting insects. The spath is usually green and can be quite large, sometimes exceeding the size of the spadix it encloses. In some species, the spath may be modified to form a pseudanthium, which is a false flower that mimics the appearance of a true flower to attract pollinators.

The spadix, on the other hand, is the inflorescence, or flower cluster, of the plant. It is a cylindrical structure that contains the actual flowers, which are typically small and inconspicuous. The spadix is usually enclosed within the spath and is supported by a central column called the spadix column. The flowers within the spadix are often unisexual, meaning they have either male or female reproductive parts, but not both. This arrangement is common in plants that rely on wind or insects for pollination.

The relationship between the spath and spadix is crucial for the reproduction of these plants. The spath serves as a protective cover for the spadix, helping to shield the delicate flowers from environmental stressors. Additionally, the spath often plays a role in attracting pollinators, as its vibrant colors and distinctive shapes can be quite appealing to insects. Once pollinated, the flowers within the spadix develop into fruits, which contain the seeds of the plant.
