Durian

Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Malvales
Family: Malvaceae (Bombacaceae)
Genus: Durio L.

The durian is the fruit of trees of the genus Durio belonging to the Malvaceae, a large family which includes hibiscus, okra, cotton, mallows and linden trees. Widely known and revered in Southeast Asia as the "King of Fruits," the fruit is distinctive for its large size, unique odour, and a formidable thorn-covered husk. The unusual smell of the ripe fruit is very strong and penetrating, even when the husk of the fruit is still intact.

There are 30 recognised Durio species, all native to Southeast Asia and at least nine of which produce edible fruit. Durio zibethinus is the only species available in the international market; other species are sold in their local region.

The fruit can grow up to 30 centimetres (12 in) long and 15 centimetres (6 in) in diameter,[5][6] and typically weighs one to three kilograms (2 to 7 lb). Its shape ranges from oblong to round, the colour of its husk green to brown and its flesh pale-yellow to red, depending on species. The hard outer husk is covered with sharp, prickly thorns, while the edible custard-like flesh within emits the strong, distinctive odour, which is regarded as either fragrant or overpowering and offensive. The taste of the flesh has been described as nutty and sweet.
