Cola nitida is a species of plant belonging to the family Malvaceae.

Contents

It is a tree native to the rainforests of tropical West Africa. Common names include kola nut, cola, kola and bitter kola. [1] The seeds contain caffeine and are chewed as a stimulant and used in the manufacture of soft drinks. The nuts and other parts of the tree have many uses of a ceremonial nature and in traditional medicine. The timber has multiple uses.

Description

Cola nitida is an evergreen tree growing to a height of 12 to 20 metres (39 to 66 ft). The trunk is up to 1.5 m (4 ft 11.1 in) in diameter and older trees develop buttresses. The bark is thick and fibrous, with deep longitudinal fissures. It is grey or brownish-grey, with pinkish-red wood becoming visible when the bark is damaged. The leaves have stalks and are alternate, oblong, glabrous, leathery and tough, with untoothed wavy margins and up to 33 cm (13 in). The flowers have parts in fives. They grow in panicles from the leaf axils and have no petals. Male flowers have a deeply lobed, cup-shaped calyx about 2 cm (0.8 in) in diameter with two whorls of stamens. Female flowers are larger at 5 cm (2.0 in) diameter, with five carpels. The calyx is yellow with red nectar guides. The carpels develop into a fleshy star-shaped aggregate fruit consisting of 5 pods (follicles) of up to 13 cm (5.1 in) long and 7 cm (2.8 in) wide. When ripe, the pods split open to reveal the seeds which consist of a white seed coat covering a pair of fleshy folded cotyledons which are mottled white, reddish-grey or brown. The cotyledons (the kola nut of commerce) are bitter when fresh but become more aromatic as they age. [2] [3]

Distribution

Cola nitida is native to Sierra Leone, Liberia, Ivory Coast, Ghana and Nigeria. It is a lowland tree but can be found up to altitudes of about 300 metres (980 ft) in areas with deep, rich soils and evenly distributed rainfall. It has been cultivated in other parts of tropical Africa as well as India, Jamaica, Brazil, [3] and Hawaii. [4] It can grow where there is around 1,200 millimetres (47 in) of rain but does better where the annual rainfall exceeds 1,700 millimetres (67 in), spread across eight months or more. Its temperature range is 23 to 28 °C (73 to 82 °F) and it grows on both light and heavy soils as long as they are deep. [5]

Uses

The nuts contain caffeine, theobromine and tannin. Along with the closely related Cola acuminata , which is also native to West Africa, the trees are cultivated commercially in tropical regions of the world and the nuts used in the manufacture of "cola" drinks. [2] Other ingredients of these drinks include spice oils, other aromatic compounds (sometimes including the leaves of the tree), caramel for colouring, sweeteners, phosphoric or citric acid, and carbon dioxide to provide effervescence. [2]

The nut has traditionally been used as a stimulant when chewed. It is reported to lessen fatigue, prevent hunger pangs, increase mental activity and reduce the need for sleep. Parts of the plant are also used in rituals such as weddings, child naming ceremonies, induction of village chiefs, funerals and sacrificial ceremonies. The leaves, twigs, bark, flowers and nuts are also used in traditional medicine. Cola nitida is closely related to Theobroma cacao , the cocoa tree, and the nuts have been used as a main ingredient for chocolate with a high melting point. [5]

The nut is used in dyeing and water purification. The timber has a use in building work, boat construction, furniture and joinery, musical instruments, utensils and carving. It is also useful as firewood. The pods have been used to make fertiliser and soap, and they can be used as a substitute for up to 60% of the maize in poultry feed. [5]

Kola nut Fruit of the kola tree

The term kola nut usually refers to the seeds of certain species of plant of the genus Cola, placed formerly in the cocoa family Sterculiaceae and now usually subsumed in the mallow family Malvaceae. These cola species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are used as flavoring ingredients in beverages applied to various carbonated soft drinks, from which the name cola originates.

<i>Grevillea robusta</i> Species of shrub in the family Proteaceae endemic to eastern Australia

Grevillea robusta, commonly known as the southern silky oak, silk oak or silky oak, silver oak or Australian silver oak, is a flowering plant in the family Proteaceae. It is a tree, the largest species in its genus but is not closely related to the true oaks, Quercus. It is a native of eastern coastal Australia, growing in riverine, subtropical and dry rainforest environments.

Ovary (botany) Flowering plant reproductive part

In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels, and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries.

<i>Cotyledon</i> (genus) Genus of succulents

Cotyledon is one of some 35 genera of succulent plants in the family Crassulaceae. Mostly from Southern Africa, they also occur throughout the drier parts of Africa as far north as the Arabian Peninsula. Ten of its species are mostly confined to South Africa, where unlike Tylecodon, they occur commonly in both the winter and summer rainfall regions. They may be found on coastal flats and rocky hillsides, or as cremnophytes on cliff faces. Their decussate, evergreen leaves are very variable in shape, even within some species, but the flowers are, apart from colour, very similar.

<i>Archidendron pauciflorum</i> Species of plant

Archidendron pauciflorum, commonly known as djenkol, jengkol or jering is a species of flowering tree in the pea family, Fabaceae. It is native to Southeast Asia, where the seeds are a popular dish. They are mainly consumed in Thailand, Malaysia, Myanmar, and Indonesia and prepared by frying, boiling, or roasting and are also eaten raw. The beans are mildly toxic due to the presence of djenkolic acid, an amino acid which causes djenkolism. The beans and leaves of the djenkol tree are traditionally used for medicinal purposes such as purifying the blood. To date, djenkol is traded on local markets only.

<i>Pentaclethra macroloba</i> Species of legume

Pentaclethra macroloba is a large and common leguminous tree in the genus Pentaclethra native to the wet tropical areas of the northern Neotropics, which can form monocultural stands in some seasonally flooded habitats. It has giant, bipinnate leaves shaped like feathers. It uses seed dispersal by water to establish itself in new areas, having floating seeds that are left behind after the waters recede after floods or tides. It has hard timber which is not very resistant to rot in the tropics, but it can be treated, has a pretty pink-red colour when dry, and has a number of uses. Oil used in cosmetics is extracted from the large seeds. In the northern Amazon region the bark is used in herbal medicine as an antivenom, and in the Guianas the bark has been used as a fish poison. Despite their toxicity, the seeds are eaten by variegated squirrels, parrots and macaws, and serve as the nurseries of the larvae of the moth Carmenta surinamensis.

<i>Lecythis zabucajo</i> Species of flowering plant

Lecythis zabucajo, the sapucaia or paradise nut, is a large nut-producing tree occurring in the Guianas, Suriname, Venezuela, Ecuador, Honduras and Brazil, and which distribution range is much the same as that of the greater spear-nosed bat. Although not singling out Lecythis zabucajo, Jacques Huber noted in 1909 that fruit bats played the most important role in seed dispersal in Amazonian forests. The quality of its nuts led to the species' being introduced to numerous tropical countries, notably Trinidad, where it has flourished. The nuts are a valuable food resource and yield oil suitable for cooking and domestic use.

<i>Cola</i> (plant) Genus of plants

Cola is a genus of trees native to the tropical forests of Africa, classified in the family Malvaceae, subfamily Sterculioideae. Species in this genus are sometimes referred to as kola tree or kola nut for the caffeine-containing fruit produced by the trees that is often used as a flavoring ingredient in beverages. The genus was thought to be closely related to the South American genus Theobroma, or cocoa, but the latter is now placed in a different subfamily. They are evergreen trees, growing up to 20 m tall, with glossy ovoid leaves up to 30 cm long and star-shaped fruit.
