Theobroma is a genus of flowering plants in the mallow family, Malvaceae. It was previously classified as a member of Sterculiaceae, which has been incorporated into Malvaceae to make it monophyletic. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America. [3]

Contents

The seeds of the cacao tree ( Theobroma cacao ), the best known species of the genus, are used for making chocolate. Cupuaçu (Theobroma grandiflorum), mocambo (Theobroma bicolor) and capacui (Theobroma speciosum) are also of economic importance.

Taxonomy

It was published by Carl Linnaeus in 1753. [2] [4] The lectotype Theobroma cacao L. was designated in 1929. [2]

Etymology

The generic name is derived from the Greek words θεόςtheos meaning "god" [5] and βρῶμαbroma meaning "food" [6] translating to "food of the gods". [7]

Uses

Several species of Theobroma produce edible seeds, notably cacao, cupuaçu, and mocambo. Cacao is commercially valued as the source of cocoa and chocolate. [10]

Theobroma species are used as food plants by the larvae of some moths of the genus Endoclita , including E. chalybeatus , E. damor , E. hosei and E. sericeus . The larvae of another moth, Hypercompe muzina , feed exclusively on Theobroma cacao.

An active ingredient of cacao, theobromine, is named for the genus.

<i>Theobroma cacao</i> Species of tree grown for its seeds

Theobroma cacao is a small evergreen tree in the family Malvaceae. Its seeds - cocoa beans - are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Although the tree is native to the tropics of the Americas, the largest producer of cocoa beans in 2022 was Ivory Coast.

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.

<i>Theobroma grandiflorum</i> Species of tree

Theobroma grandiflorum, commonly known as cupuaçu, also spelled cupuassu, cupuazú, cupu assu, or copoazu, is a tropical rainforest tree related to cacao. Native and common throughout the Amazon basin, it is naturally cultivated in the jungles of northern Brazil, with the largest production in Pará, Amazonas and Amapá, Colombia, Bolivia and Peru. The pulp of the cupuaçu fruit is consumed throughout Central and South America, especially in the northern states of Brazil, and is used to make ice creams, snack bars, and other products.

<i>Platonia</i> Genus of trees

Common names include bacuri, maniballi, naranjillo and bacurizeiro.

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

Malvaviscus is a genus of flowering plants in the mallow family, Malvaceae. Common names for species in this genus include Turk's cap mallow, wax mallow, sleeping hibiscus, and mazapan. It belongs to a group of genera that differ from the closely related Hibiscus in possessing a fruit divided into 5 separate parts, and having a style surmounted by 10, rather than 5, capitate or capitellate stigmas. Among those genera Malvaviscus is distinguished by having auriculate petals and red, fleshy fruits. The generic name is derived from the Latin words malva, meaning "mallow," and viscus, which means "sticky," referring to the mucilaginous sap produced by members of the genus. The fruit can be used to make jelly or syrup. Both the fruit and flowers are used to make herbal teas.

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.
