Durio is a genus of plants in the family Malvaceae. Several species produce an edible fruit known as durian, the most common species being Durio zibethinus . There are 30 recognized species in the genus Durio, but only nine produce edible fruit. [2]

Taxonomy

Durio sensu lato has 30 recognised species. [2] Durio sensu stricto comprises 24 of these species. The 6 additional species included in Durio s.l. are now considered by some to comprise their own genus, Boschia. [3] [4] Durio s.s. and Boschia have indistinguishable vegetative characteristics and many shared floral characteristics. The crucial difference between the two is that anther locules open by apical pores in Boschia and by longitudinal slits in Durio s.s. [5] These two genera form a clade that is sister to another genus in the tribe Durioneae, Cullenia . These three genera together form a clade that is characterised by highly modified (mono- and polythecate, as opposed to bithecate) anthers. [3]

The genus Durio is placed by some taxonomists in the family Bombacaceae, or by others in a broadly defined Malvaceae that includes Bombacaceae, and by others in a smaller family of just seven genera, Durionaceae. [1] [6] [7]

Durio is often included in Bombacaceae because of the presence of monothecate anthers, as opposed to the bithecate anthers common to the rest of the mallows (and angiosperms, in general). However, the first studies to examine mallow phylogeny using molecular data found that the tribe Durioneae should be placed in the subfamily Helicteroideae of an expanded Malvaceae. The authors of these studies hypothesise that monothecate anthers have most likely evolved convergently in Durioneae and in the Malvatheca clade (comprising Malvaceae s.l. subfamilies Malvoideae and Bombacoideae). [8] [9]

Description

There are 30 recognized species in the genus Durio, but only nine produce edible fruit. Durian is the only species available on the international market: the other species are sold only in their local regions. The name "durian" is derived from the Indo-Malay word "duri" which refers to the fruit's many protuberances.

Often considered the king of fruits, [10] durian is distinguished by its large size, repulsive odor, and fearsome thorny husk. The fruit can grow up to 30 centimeters long and 15 centimeters in diameter, and typically weighs one to three kilograms. Its shape ranges from oblong to round, the color of its husk from green to brown, and its flesh from pale yellow to red, depending on the species.

The edible flesh emits a distinctive odor that is strong and penetrating, even when the husk is intact. The smell, depending on the person, evokes rotting onions, turpentine, or even sewage, yet to others it's odor is welcoming and appetizing. The persistence of its odor has led to its ban in some hotels and public transport in Southeast Asia.

On March 4, 2023, a plane flying from Istanbul to Barcelona was forced to turn back because of the nauseating odor of the tropical fruit, transported in the hold.

The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within nine families. The order is placed in the eurosids II, which are part of the eudicots.

<span class="mw-page-title-main">Malvaceae</span> Family of flowering plants

Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao, roselle and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow), and Tilia. The genera with the largest numbers of species include Hibiscus, Pavonia, Sida, Ayenia, Dombeya, and Sterculia.

<span class="mw-page-title-main">Bombacaceae</span> Family of flowering plants

Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus Bombax. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic point of view, and currently the preference is to transfer most of the erstwhile family Bombacaceae to the subfamily Bombacoideae within the family Malvaceae in the order Malvales. The rest of the family were transferred to other taxa, notably the new family Durionaceae. Irrespective of current taxonomic status, many of the species originally included in the Bombacaceae are of considerable ecological, historical, horticultural, and economic importance, such as balsa, kapok, baobab and durian.

<i>Diospyros</i> Genus of trees and shrubs

Diospyros is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants.

Sterculiaceae was a family of flowering plant based on the genus Sterculia. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae.

<i>Sterculia</i> Genus of flowering plants

Sterculia is a genus of flowering plants in the mallow family, Malvaceae: subfamily Sterculioideae. Members of the genus are colloquially known as tropical chestnuts. Sterculia may be monoecious or dioecious, and its flowers unisexual or bisexual.

<span class="mw-page-title-main">Malvoideae</span> Subfamily of flowering plants

Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus Malva.

The Malvoideae of Kubitzki and Bayer includes 4 tribes:

<i>Durio dulcis</i> Species of tree

Durio dulcis, known as durian marangang, red durian, tutong, or lahung, is a fairly large tree in the genus Durio. It can grow up to 40 m tall. The husk of its fruit is dark red to brown-red, and covered with slender 15–20 mm long spines. The fruit flesh is dark yellow, thin, and deep caramel-flavored, with a turpentine odor. The fruit of this species is considered by many to be the sweetest of all durians.

<i>Scaphium</i> Genus of plants
