In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the pip (UK), pit (US), stone, or pyrena) of hardened endocarp with a seed (kernel) inside. Drupes do not split open to release the seed, i.e., they are indehiscent. [1]
The seed is a drupe varied in size and shape from oblong to ovate or date shape. The fruit is seated on the perianth tube. The fruit is seated on the perianth tube. Seed dispersal by vertebrate animals.
The true fruit of the cashew tree is a kidney-shaped or boxing glove-shaped drupe that grows at the end of the cashew apple. [3] The drupe first develops on the tree and then the pedicel expands to become the cashew apple. [3] The drupe becomes the true fruit, a single shell-encased seed, which is often considered a nut in the culinary sense.
Along with the peach, it is classified in the subgenus Amygdalus, distinguished from the other subgenera by corrugations on the shell surrounding the seed. [3] The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. [4]
The fruit is a drupe 5–7 cm (2– 2 + 3 ⁄ 4 in) long and 3–5.5 cm (1 + 1 ⁄ 8 – 2 + 1 ⁄ 8 in) broad containing a single seed; it is green at first, then yellows and finally turns to red when ripe.
The fruit is a dark blue-black drupe 1 cm (0.39 in) long containing a single seed, borne on a red fleshy club-shaped pedicel 2 cm (0.79 in) long; it is ripe in late summer, with the seeds dispersed by birds. The cotyledons are thick and fleshy. All parts of the plant are aromatic and spicy.
Fruits are usually of medium size, between 2–7 centimetres (0.79–2.76 in) in diameter, globose to oval. The flesh is firm and juicy. The fruit's peel is smooth, with a natural waxy surface that adheres to the flesh. The plum is a drupe, meaning its fleshy fruit surrounds a single hard fruitstone which encloses the fruit's seed.
The ripe fruit is a red, ellipsoidal, berrylike drupe, rich in lipids, about 1 cm (1 ⁄ 2 in) long and is eaten by several bird species. [11] It has a "turpentine-like" taste and aromatic scent, and contains a large seed. Spicebush is dioecious (plants are either male or female), so that both sexes are needed in a garden if one wants drupes ...
