Deinbollia oblongifolia is a shrub or small tree in the family Sapindaceae. It is commonly known as the dune soap-berry and is found in coastal vegetation from the Eastern Cape of South Africa, through KwaZulu-Natal [1] to southern Mozambique and Eswatini. It is named after Peter Vogelius Deinboll (1783–1876), a Danish botanist and plant collector.
These plants can grow up to 9 metres (30 ft) tall. [1] The stem often branches low down and the bark is grey brown. The leaves are compound, up to 50 centimetres (20 in) long and clustered at the ends of the branches. [1] The flowers are white, [1] or cream [2] and produced on branched flowering heads at the ends of the branches. [1] The fruit are rounded; green and velvety when young to yellow and smooth when ripe. [1] The dune soap-berry may be confused with a young forest mahogany ( Trichilia dregeana ) because of the similar shaped compound leaves, however the dune soap-berry has paler green slightly matt leaves compared to the forest mahogany, which has a darker green leaf that is slightly more glossy. [2] The leaves of the dune soap-berry are also hard textured (when mature) and not held flat as in Trichilia dregeana. [1]
The fruit is eaten by people. [1] [2] The leaves can be eaten as spinach, and the seeds can be lathered in water and used as soap (hence the name "soap-berry"). [2] The roots are used in traditional Zulu medicine for stomach complaints. [1] These shrubs are also valuable garden plants, especially in wildlife gardens. [2]
The flowers attract hordes of insects [3] including; moths, butterflies, bees, wasps, ants [1] and beetles. The leaves are fed on by the larvae of several butterflies, including; gold-banded forester ( Euphaedra neophron ), forest queen ( Euxanthe wakefieldi ) and the purple-brown hairstreak ( Hypolycaena philippus ). [4] Various Deudorix butterfly species' larvae also feed on these trees, [3] including the larvae of the black-and-orange playboy ( Deudorix dariaves ) [2] and the apricot playboy ( Deudorix dinochares ) [5] which both eat the fruits of Deinbollia oblongifolia. The larvae of the African peach moth ( Egybolis vaillantina ) also feed on the leaves, [5] [6] and the fruit are also eaten by birds (including the sombre greenbul ( Andropadus importunus ) [2] ) and monkeys. [1] Charaxes butterflies feed on the fermenting fruits, [2] and the green-veined charaxes ( Charaxes candiope ), pearl charaxes ( Charaxes varanes ), satyr charaxes ( Charaxes ethalion ), forest-king charaxes ( Charaxes xiphares ), white-barred charaxes ( Charaxes brutus ) and the Natal tree nymph ( Sevenia natalensis ) have all been observed feeding on the sap of Deinbollia oblongifolia. [5] Furthermore, these trees are browsed by game animals. [1]
Carissa is a genus of shrubs or small trees native to tropical and subtropical regions of Africa, Australia and Asia. Until recently about 100 species were listed, but most of them have been relegated to the status of synonyms or assigned to other genera, such as Acokanthera.
Albizia adianthifolia is a tree in the family Fabaceae. It is commonly known as the flat-crown. Its range extends from eastern South Africa to Tropical Africa.
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.
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.
Millettia grandis is a species of plant in the family Fabaceae from South Africa. It is commonly called umzimbeet which is a name derived from the isiZulu name umSimbithwa.
Trichilia emetica is a tree in the family Meliaceae, commonly known as the Natal mahogany. It is an evergreen tree, with handsome glossy dark green leaves and a wide spreading crown. Its sweet-scented flowers attract bees and birds.
KwaZulu-Natal coastal lowland forest is a subtropical forest type that was once found almost continuously along the low-lying coastal areas of KwaZulu-Natal, South Africa. It still exists in protected areas, but much has been cleared for sugar-cane plantations and housing developments.
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.
Margaritaria discoidea is a tree in the family Phyllanthaceae, commonly known as the pheasant-berry, egossa red pear or bushveld peacock-berry. These trees are native to the warmer, higher rainfall areas of Africa.
Sevenia boisduvali, the Boisduval's tree nymph, is a butterfly in the family Nymphalidae. There are four subspecies; all native to Africa.
Hypolycaena lochmophila, the coastal hairstreak, is a butterfly of the family Lycaenidae. It is found in lowland forest in northern KwaZulu-Natal, Malawi and eastern Zimbabwe.
Deudorix dariaves, the black-and-orange playboy, is a butterfly of the family Lycaenidae. It is found from South Africa to Mozambique and to the coast of Kenya. In South Africa it is found along the coast of KwaZulu-Natal and north along the escarpment foothill forests to Mpumalanga and Limpopo.
Deudorix dinomenes, the orange playboy, is a butterfly of the family Lycaenidae. It is found in Senegal, Guinea, Sierra Leone, Ivory Coast, Ghana, Benin, Nigeria, Cameroon, the Central African Republic, the Democratic Republic of the Congo, Uganda, Sudan, Kenya, Tanzania, Malawi, Zambia, Zimbabwe, Mozambique and South Africa.
Euxanthe wakefieldi, the forest queen, is a butterfly of the family Nymphalidae. It is found in South Africa, from KwaZulu-Natal to Eswatini and the north-eastern Limpopo, north into eastern Africa. The wingspan is 65–72 mm for males and 80–90 mm for females. Adults are on wing year round, with a peak from March to June. The larvae feed on Deinbollia species, Sapindus, Blighia, and Phialodiscus species. They are notable for their spectacular horns.

Erianthemum dregei is a species of parasitic plant in the family Loranthaceae, and is commonly known as the hairy mistletoe or wood flower.
Maerua cafra (DC.) Pax is a small Southern African tree belonging to Capparaceae, the caper family, occurring eastwards along the coast from Knysna, then further inland and northwards through KwaZulu-Natal and Eswatini to the Transvaal, southern Mozambique and southern Zimbabwe. The genus Maerua comprises about 60 species found in Africa and Asia.
