Name

Specific epithet

The specific epithet 'speciosum' is used to indicate that a plant is aesthetically pleasing; [4] it is a neuter form of 'speciosus', [5] which is Latin for 'beautiful'. [6]

Common names

Theobroma speciosum has a number of common names: [7]

Description

Theobroma speciosum is an evergreen tree that grows up to 15 m (49 ft) tall. [9] The trunk is straight, [7] with plagiotropic (horizontally growing) [10] side branches. [11] The canopy is small. [7] Its leaves are simple, and have a coriaceous (leather-like) [12] surface with trichomes (hairs). [11] [13] Leaf arrangement is distichous (leaves alternate between one side of the stem and the other). [11] [14] Flowers are red, [15] and grow on the trunk in dense clusters. [7] [16] Fruits are 10 cm (3.9 in) in length, and comprise approximately 20 seeds surrounded by a white flesh, [7] which in turn is surrounded by a capsule. [11]

Distribution

Theobroma speciosum is native to: [2]

Ecology

The fruit of T. speciosum is a food source for primates and rodents. [17] Its flowers are pollinated by flying insects. [18]

Uses

The fruit of T. speciosum is the third from the left.

Food

The flesh of the fruit of is eaten by the Ka'apor and Tacana peoples. [19] The seeds are used to make chocolate, [13] and could also be used to make cocoa butter substitutes. [20]

The flowers are edible, and contain high concentrations of antioxidants. [21]

Hygiene

The fruit capsules can be used to make soap and deodorant. [19]

Genetic resource

As a crop wild relative, [22] T. speciosum could be used as a source of genetic variability for T. cacao , [17] which is widely cultivated for its cocoa beans.

Ornamental

T. speciosum is occasionally grown in gardens as an ornamental plant. [3] [23]

Diseases

Colletotrichum luxificum, a species of pathogenic fungus, [24] can cause witch's broom disease in Theobroma speciosum. [25] [26]

Notes

  1. Theobroma speciosumWilld. ex Spreng. is not to be confused with Theobroma speciosumWilld. ex Mart. , a synonym of Theobroma grandiflorum (Willd. ex Spreng.) K.Schum., which is a different species of Theobroma. [1]

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

Coffea is a genus of flowering plants in the family Rubiaceae. Coffea species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste.

<span class="mw-page-title-main">Cocoa bean</span> Fatty seed of Theobroma cacao which is the basis of chocolate

The cocoa bean or simply cocoa, also called cacao, is the dried and fully fermented seed of Theobroma cacao, from which cocoa solids and cocoa butter can be extracted. Cocoa beans native to the Mexican pre Colombian territory were extended to Ecuadorian Amazon rainforest and are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink.

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

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. Native to the tropics of the Americas, the largest producer of cocoa beans in 2018 was Ivory Coast, at 2.2 million tons. Its leaves are alternate, entire, unlobed, 10–50 cm (4–20 in) long and 5–10 cm (2–4 in) broad.

<span class="mw-page-title-main">Midge</span> Common name for several species of flies

A midge is any small fly, including species in several families of non-mosquito Nematoceran Diptera. Midges are found on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae and Simuliidae, are vectors of various diseases. Many others play useful roles as prey for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles.

<i>Theobroma</i> Genus of flowering plants in the mallow family Malvaceae

Theobroma is a genus of flowering plants in the mallow family, Malvaceae, that is sometimes classified as a member of Sterculiaceae. It contains roughly 20 species of small understory trees native to the tropical forests of Central and South America.

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.

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

Grewioideae is a subfamily of the family Malvaceae and was first described by Hochreutiner.

It contains a number of genera that were previously placed in the defunct family Tiliaceae.

Phytophthora megakarya is an oomycete plant pathogen that causes black pod disease in cocoa trees in west and central Africa. This pathogen can cause detrimental loss of yield in the economically important cocoa industry, worth approximately $70 billion annually. It can damage any part of the tree, causing total yield losses which can easily reach 20-25%. A mixture of chemical and cultural controls, as well as choosing resistant plant varieties, are often necessary to control this pathogen.

<i>Moniliophthora perniciosa</i> Species of fungus

Moniliophthora perniciosa is a fungus that causes "witches' broom disease" (WBD) of the cocoa tree T. cacao. This pathogen is currently limited to South America, Panama and the Caribbean, and is perhaps one of the best-known cocoa diseases, thought to have co-evolved with cocoa in its centre of origin.

<i>Moniliophthora roreri</i> Species of fungus

Moniliophthora roreri is a basidiomycete fungus that causes frosty pod rot disease, one of the most serious problems for cacao production in Latin America. This disease and together with witches’ broom disease and black pod rot constitute the cacao disease trilogy. It causes serious losses in southwestern parts of South America; spores are dry and powdery and are spread easily by water movement, wind, or movement of pods; disease spread is highest during periods of high rainfall.

<i>Cacao swollen shoot virus</i> Species of virus

Cacao swollen shoot virus (CSSV) is a plant pathogenic virus of the family Caulimoviridae that primarily infects cacao trees. It decreases cacao yield within the first year of infection, and usually kills the tree within a few years. Symptoms vary by strain, but leaf discoloration, stem/root swelling, and die-back generally occur. The virus is transmitted from tree to tree by mealybug vectors. It was first discovered in Ghana in 1936, and is currently endemic in Togo, Ghana and Nigeria. Over 200 million trees have already been claimed by this disease, which has prompted Ghana to launch the most ambitious and costly eradication effort of any country in the world against a viral plant disease.

Lumnitzera is an Indo-West Pacific mangrove genus in the family Combretaceae. An English common name is black mangrove. Lumnitzera, named after the German botanist, Stephan Lumnitzer (1750-1806), occurs in mangroves from East Africa to the Western Pacific, and northern Australia.

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

Theobroma bicolor, known commonly as the mocambo tree, jaguar tree, balamte, or pataxte, among various other common names, is a tree in the genus Theobroma, which also contains the better-known Theobroma cacao. It is found in Central and South America, including stretches of the Amazon rainforest in Brazil, Colombia, Ecuador, and Peru.

Panopsis is a genus of trees in the family Proteaceae. The species, which occur in Central and South America, include: Newer species that can be considered part of the Panopsis genus has been discovered recently, called Panopsis magnifruta. Common areas where Panopsis species are seen to grow in are described to have elevated groundwater levels.
