aggregate of drupelets

In botany, an aggregate fruit is formed from a single flower with multiple pistils, where each pistil develops into a small drupe called a drupelet. Examples of aggregate fruits include raspberries and blackberries, which are composed of many tiny drupelets clustered together. A drupe itself is a simple fleshy fruit, typically containing a single seed, like a cherry or olive. It has a thin outer skin, a fleshy middle layer, and a hard, stony inner layer called the pit.12
