Mimusops afra [3] (coastal red milkwood, Afrikaans : Kusrooimelkhout, Xhosa : Umthunzi, Sepedi: Mmupudu, Zulu : Umkhakhayi) [4] is a species of tree in family Sapotaceae. This tree is found in coastal dune vegetation in Southern Africa from the Eastern Cape, through KwaZulu-Natal to southern Mozambique.
Mimusops afra is a small to medium-sized tree. The stem is up to 50 cm (20 in) in diameter, often gnarled or twisted with dark grey bark which is wrinkled longitudinally. [5] These trees may reach 15–25 m (49–82 ft) [6] [7] in height, but are shorter on the seaward side of the dunes [8] where they rarely exceed 5m tall and where the foliage suffers under salt spray and sea winds. [5] It may be dominant in sheltered dune forest behind the littoral zone, where it can reach 20 m (66 ft) in height [5] with some protection from the salt wind where forests develop with canopies as tall as 30 m (98 ft). [8]
The leaves are alternate, hard and leathery with rounded or blunt tips. Older leaves are blue-green above and paler on the underside. Young leaves are light green.
The creamy-white star-like flowers are 10–20 mm (0.39–0.79 in) in diameter and found in small bunches in the leaf axils. [9] [7]
The fruits are about 15–20 mm (0.59–0.79 in) long and are fat, roundish to oval, red or orange-red when ripe, with a sweet starchy pulp and containing a single oval, shiny brown or blackish seed. [10]
The fruit are eaten by people, vervet monkeys, bushpigs, Cape parrots, black-bellied glossy starlings and yellow-streaked bulbuls. [10] These trees serve to lift the vegetative canopy in coastal dune vegetation, thereby allowing space and protection for more delicate plant species such as Isoglossa woodii (which is fed on by blue duiker) and the large-leaved dragon tree ( Dracaena aletriformis ). The robust structure of these trees also allows support for climbing plants such as Rhoicissus rhomboidea . Monkeys and birds spread the seeds of Mimusops afra, which are also buoyant and often wash up along the shore. [10]
Mimusops afra is protected (in South Africa) in terms of the National Forest Act of 1998. Protected tree species may not be cut, disturbed, damaged or destroyed, and their products may not be possessed, collected, removed, transported, exported, donated, purchased or sold, except under licence granted by the Department of Forestry or a delegated authority. [11]
The etymology of the original species name caffra is related to kaffir, an ethnic slur used towards black people in Africa. At the July 2024 International Botanical Congress, a vote was held with the result that "caffra" related names will be emended to afra related ones, with the implementation of this being done at the end of July 2024.

Dovyalis afra, commonly known as the Kei apple, is a small to medium-sized tree, native to southern Africa. Its distribution extends from the Kei River in the south, from which the common name derives, northwards along the eastern side of the continent to Tanzania. The ripe fruits are tasty, reminiscent of a small apple.
Encephalartos woodii, Wood's cycad, is a rare cycad in the genus Encephalartos, and is endemic to the oNgoye Forest of KwaZulu-Natal, South Africa. It is one of the rarest plants in the world, being extinct in the wild with all specimens being clones of the type. The specific and common name both honour John Medley Wood, curator of the Durban Botanic Garden and director of the Natal Government Herbarium of South Africa, who discovered the plant in 1895.
Mimusops zeyheri is a medium-sized evergreen tree belonging to the family Sapotaceae and widely distributed in rocky places from the east coast of southern Africa, inland and northwards to tropical Africa. It is commonly known as the moepel or Transvaal red milkwood. It is closely related to Mimusops obovata and M. caffra, both of which are South African trees.
Protea afra, native to South Africa, is a small tree or shrub which occurs in open or wooded grassland, usually on rocky ridges. Its leaves are leathery and hairless. The flower head is solitary or in clusters of 3 or 4 with the involucral bracts a pale red, pink or cream colour. The fruit is a densely hairy nut. The species is highly variable and has several subspecies.
Erythrina afra, the coast coral tree or African coral tree, is a tree native to southeastern Africa, which is often cultivated and has introduced populations in California and India. All the 17 species of coral tree in the genus Erythrina are collectively considered the official tree of Los Angeles, California in the United States.
Barringtonia racemosa, commonly known as powder-puff tree, is a species of tree in the family Lecythidaceae. It is found in coastal swamp forests and on the edges of estuaries in the Indian Ocean, starting at the east coast of Mozambique and KwaZulu-Natal to Madagascar, India, Sri Lanka, Malaysia, Maldives, Thailand, Laos, southern China, northern Australia, coastal Taiwan, the Ryukyu Islands and many Polynesian islands.
Pigeon Valley is a Natural Heritage Park and formally declared municipal nature reserve in Durban, South Africa. It is an unusual example of an urban reserve with very high levels of biodiversity. It was established to provide protection for the Natal elm and other forest giants of the coastal climax forest. Another rare tree that occurs here is Natal forest loquat, which is endemic to the Durban area and to oNgoye Forest.
Areas of forest which grow in KwaZulu-Natal, South Africa mostly on south facing slopes in higher rainfall areas, and along the humid coastal areas. Different types of forest can be identified by their species composition which depends mostly on the altitude, latitude and substrate in which they grow. South facing slopes are favourable for the development of forest as they are more shaded, and therefore cooler and retain more moisture than the northern slopes. The extra moisture on the south slopes is not only favoured by forest trees, but also helps to prevent or subdue wildfires. Fires can also be blocked by cliff faces and rocks or boulders on these slopes, and by streams or rivers at the base of the slopes. The coastal regions are conducive to forest formation, because of high rainfall and humidity which are favoured by forest trees and also help to prevent or subdue fires. The rivers of the coastal areas are also broader than further inland, which may often prevent fires from spreading long distances, and fires generally burn uphill and therefore more often away from areas at low altitude.
Rauvolfia afra is a tree in the family Apocynaceae. It is commonly known as the quinine tree. These trees are distributed from the Eastern Cape of South Africa to tropical Africa and are found in low-lying forests near rivers and streams, or on floodplains.
The Maputaland-Pondoland-Albany Hotspot (MPA) is a biodiversity hotspot, a biogeographic region with significant levels of biodiversity, in Southern Africa. It is situated near the south-eastern coast of Africa, occupying an area between the Great Escarpment and the Indian Ocean. The area is named after Maputaland, Pondoland and Albany. It stretches from the Albany Centre of Plant Endemism in the Eastern Cape Province of South Africa, through the Pondoland Centre of Plant Endemism and KwaZulu-Natal Province, the eastern side of Eswatini and into southern Mozambique and Mpumalanga. The Maputaland Centre of Plant Endemism is contained in northern KwaZulu-Natal and southern Mozambique.
Isoglossa woodii, commonly known as buckweed, is a monocarpic shrub of the family Acanthaceae, growing up to 4 m tall. It grows in colonies in coastal forest areas of KwaZulu-Natal and marginally into Eastern Cape and Free State of South Africa.
KwaZulu-Natal Dune Forest is a subtropical forest type that was once found almost continuously along the coastal dunes of KwaZulu-Natal, South Africa. This vegetation type develops in sheltered areas behind the littoral zone, where with some protection from the salt wind it may develop with canopies as tall as 30 m. It still exists in protected areas, but much has been degraded by human activity. Coastal dune forest covers approximately 1% of the land area of KwaZulu-Natal, and is a habitat type seriously threatened from human population pressure and development, particularly titanium mining.
Dracaena aletriformis is commonly known as the large-leaved dragon tree. These plants are found in forest in the eastern areas of South Africa from Port Elizabeth to northern and eastern Limpopo. They are also found in Eswatini, but are most common in the coastal and dune forests of KwaZulu-Natal.
Rhoicissus rhomboidea, also known as the glossy forest grape, glossy wild grape, ropewood, bastard forest grape and grape ivy, is an evergreen climbing plant in the family Vitaceae that is native to the eastern forests of southern Africa.
Senegalia afra, also known as hook-thorn or Acacia afra, is a tree that occurs commonly in southern Africa. Though it is cultivated, it often occurs naturally in Gauteng suburban gardens, together with Acacia karroo and Acacia robusta.
Ximenia afra, the sourplum, is a small tree or small shrub that is thinly branched. It is part of the Olacaceae family which is native throughout tropical regions. In particular, the sourplum is native to regions in South East Africa, mainly Botswana, Kenya, Malawi, Mozambique, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. Sourplum fruits are generally sour, with a dry aftertaste, and contain significant amounts of potassium. The tree is fairly hardy, with frost resistance and drought tolerance. The tree, fruit, seed, leaves, and roots are all used for human consumption, medicinally, or for fuel.
Scepocarpus trinervis (Hochst.) Friis & Immelman is a softly woody dioecious liane, sometimes epiphytic, climbing to 20 m, often to the canopy and hanging in festoons. It is one of some 44 species of Urera belonging to the nettle family Urticaceae. It is known in English as the tree climbing-nettle or climbing nettle.
Dracaena mannii Baker or small-leaved dragon tree, is a small to medium-sized tree, though recorded up to 30 m tall with stem to 2 m in diameter in Cameroon and Gabon. It occurs from Senegal to Angola along the African west coast, is widespread in tropical Africa and is found along the African east coast from Kenya to Kosi Bay in northern KwaZulu-Natal. It prefers lowland, submontane and montane forests which are either moist and evergreen, swampy or on coastal dunes. It is also found along forest edges, in clearings and on river banks from sea level to 1,800 metres. It is one of some 120 species currently recognised in its genus, which occur primarily in Africa and southern Asia with a single vagrant species in Central America. The species is named after Gustav Mann (1836–1916), a German botanist, who corresponded with John Gilbert Baker.
