An aril is a botanical term used to describe a specialized structure that is found on certain seeds. It refers to a fleshy and often brightly colored outgrowth or appendage that develops from the seed coat or the stalk of the seed. The aril functions as a protective covering or attractant to aid in seed dispersal by attracting animals or enticing them to consume the seed.
Arils are typically found on seeds of various flowering plants, such as certain tropical and subtropical trees and shrubs. They vary in size, shape, and color, depending on the plant species. Examples of seeds with arils include pomegranates, yews, and passion fruits. Tamarind is another prime example, where the aril surrounds the seeds within the pod.
The aril is distinct from other seed structures such as the seed coat and endosperm. It is important to note that an aril should not be confused with an edible fruit itself, as it is an accessory tissue to the seed rather than a complete fruit.
The presence of an aril plays a significant role in seed dispersal, as it aids in attracting animals and ensuring the successful distribution of seeds. This mechanism is particularly efficient when animals eat the entire fruit or aril, digest the flesh, and then excrete the seed intact, effectively spreading the plant's genetic material to new locations. Thus, the aril serves as a crucial adaptation for seed survival and reproductive success in many plant species.
In botany, an outgrowth from any part-stalk, integument, or placenta-of a seed.

The word aril is derived from the Latin word aris, which refers to the fine seed coat or husk surrounding a seed. It has been used in botany since the early 18th century to describe the fleshy or parchment-like covering that develops around certain seeds or seedpods. The etymology of the word can ultimately be traced back to the Greek word arios, meaning bread.
