- Avocado: The avocado, a tree likely originating from southcentral Mexico, is classified as a member of the flowering plant family Lauraceae. The fruit of the plant also called an avocado, is botanically a large berry containing a single large seed.
Apricot: An apricot is a fruit or the tree that bears the fruit, of several species in the genus Prunus. Usually, an apricot is from the species P. armeniaca, but the fruits of the other species in the Prunus sect. Armeniaca are also called apricots.
- Mango: A mango is a stone fruit produced from numerous species of tropical trees belonging to the flowering plant genus Mangifera, cultivated mostly for their edible fruit. Most of these species are found in nature as wild mangoes. The genus belongs to the cashew family Anacardiaceae.
- Plum: A plum is a fruit of some species in Prunus subg. Prunus. Mature plum fruits may have a dusty-white waxy coating that gives them a glaucous appearance. This is an epicuticular wax coating and is known as “wax bloom”. Dried plums are called prunes, which have a dark, wrinkled appearance.
- Olive: The olive, known by the botanical name Olea europaea, meaning “European olive”, is a species of small tree in the family Oleaceae, found traditionally in the Mediterranean Basin.
Many, many fruits exist which only contain a single seed. In fact, one particular group of frequently single-seeded fruits has a special botanical name: drupes.
Examples of drupes are numerous in nature:
- The species of the genus Prunus, including plums (all types, including damson, sloe/blackthorn, greengage, Mirabelle, etc.), apricots, pluots (and all other plum-apricot hybrids), peaches, nectarines, cherries (both sour and sweet), chokecherries, and almonds (although the fruit part of the almond is not fleshy, juicy, and sweet, but rather are just leathery and inedible coverings around the nut that we eat).
- The various palm fruits, including dates, açaí berries, coconuts, oil palm nuts, and the fruit of the jelly palm / pindo palm.
- Mangoes and avocados, whose large seeds evolved to survive through the gut of large ice-age megafauna.
- Other assorted fruits, including olives, pistachios, cashews, jujubes, etc.
