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 Swaziland.
Description
These plants can grow up to 9 m tall.[1] The stem often branches low down and the bark is grey-brown in colour. The leaves are compound, up to 500 mm long and clustered at the ends of the branches.[1] The flowers are white[1] or cream[2] in colour, 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]
Uses
The fruit are 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]
Ecological Significance
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 ), 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]
