- Bramble

Bramble fruits such as the blackberry and the raspberry are aggregates of drupelets.

The parts of a flower, showing the stigma-style-ovary system.
An apple is a simple fleshy fruit. Key parts are the epicarp, or exocarp, or outer skin, (not labelled); and the mezocarp and endocarp (labelled).
Insertion point: There are 3 positions of insertion of the ovary at the base of a flower: I superior; II half-inferior; III inferior. The 'insertion point' is where the androecium parts (a), the petals (p), and the sepals (s) all converge and attach to the receptacle (r). (Ovary= gynoecium (g).)
In the noni, flowers are produced in time-sequence along the stem. It is possible to see a progression of flowering, fruit development, and fruit ripening.
Dewberry flowers. Note the multiple pistils, each of which will produce a drupelet. Each flower will become a blackberry-like aggregate fruit.

A dry simple fruit: milkweed (Asclepias syriaca); dehiscence of the follicular fruit reveals seeds within.
Fruits of four different banana cultivars (Bananas are berries.)
Strawberry, showing achenes attached to surface. Botanically, strawberries are not berries; they are classified as an aggregate accessory fruit.
Flower of Magnolia × wieseneri showing the many pistils making up the gynoecium in the middle of the flower. The fruit of this flower is an aggregation of follicles.
Detail of the raspberry flower: there is a clustering of pistils at the center of the flower. (A pistil consists of stigma, style, and ovary.) The stigma is the apical (at the apex) nodule that receives pollen; the style is the stem-like column that extends down to the ovary, which is the basal part that contains the seed-forming ovule.
Lilium unripe capsule fruit; an aggregate fruit.
The fruit of a pineapple includes tissue from the sepals as well as the pistils of many flowers. It is a multiple-accessory fruit.
Picking blackberries in Oklahoma
Comparing fresh fruits for fiber, potassium (K), and vitamin C. Each disk-point refers to a 100 g serving of the fresh fruit named. The size of the disk represents the amount of fiber (as percentage of the recommended daily allowance, RDA) in a serving of fruit (see key at upper right). The amount of vitamin C (as percent RDA) is plotted on the x–axis and the amount of potassium (K), in mg on the y–axis. + Bananas are high in value for fiber and potassium, and oranges for fiber and vitamin C. (Apricots are highest in potassium; strawberries are rich in vitamin C.) Watermelon, providing low levels of both K and vitamin C and almost no fiber, is of least value for the three nutrients together.
Porcelain vine is usually planted for its showy, colourful berries.

As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, the pericarp, may become fleshy (as in berries or drupes), or it may form a hard outer covering (as in nuts).

In some bramble fruits such as blackberry the receptacle, an accessory part, elongates and then develops as part of the fruit, making the blackberry an aggregate-accessory fruit.

The term bramble, a word referring to any impenetrable thicket, has in some circles traditionally been applied specifically to the blackberry or its products, though in the United States it applies to all members of the genus Rubus.

Botanically it is termed an aggregate fruit, composed of small drupelets.
