The bark is dark brown when young, turning dark grey as the tree matures, with a rough texture, forming deep horizontal grooves. They have a dense, dark green and spreading crown. The single leaves are elliptical in shape, up to 5,5 inches long and 3 inches wide with smooth or slightly wavy edges.
Older leaves have a glossy, leathery look, darker green above and a lighter green below. Young leaves and twigs are covered with downy hairs. While they are young the trees don't lose their leaves, but as the tree gets older it will shed its leaves in early spring.
New leaves will grow from June to October and be pinkish, orange or reddish in colour. It varies in colour from light, reddish brown to almost black. The Jackalberry tree is part of the Ebenaceae family, and is also known as African ebony.
The fruit of the Jackalberry tree is a favourite of many animals. The fleshy fruit is oval, almost round in shape and about 1 inch in diameter and yellow or yellow-green in colour. Five sepals of the calyx of the flower remain on the bottom of the fruit, their tips curling backwards.
Two to six wrinkled seeds can be found inside the fruit. The skin is tough but the edible fruit has a chalky, floury consistency with a lemon-sweet flavour. They can be eaten fresh or preserved. They are also dried and ground into flour. A beer and brandy is also brewed from them.
When the Jackalberry fruit is fully ripe, it turns purple, but one hardly ever sees it this colour since it is eaten by various animals long before it can get that ripe. Animals such as nyalas, impalas, warthogs, baboons and hornbills to name a few, love to eat the fruit of the Jackalberry.
It got its name because the Jackalberry seeds are also found in the dung of jackals. The leaves are eaten by elephants, rhinos, giraffes, buffaloes, and kudus. The larvae of the bushveld emperor butterfly also eat the leaves of this tree.
The heartwood is fine-grained and good for floors, high quality furniture and pestels. The trunks are used to make canoes. Tannin is contained in the leaves, bark and roots, and acts as an astringent that helps stop bleeding. The tree is also supposed to have antibiotic substances that help heal wounds.
A mixture made from the roots is used to get rid of parasites like ring worm, and dysentery and fever. It is also considered a remedy for leprosy. Seeds are eaten as nuts. Fruits are often used to brew beer or fermented for wine. Fruit and plant parts contain tannin.
The Jackalberry tree is found throughout Africa, from Senegal and the Sudan to Namibia and the northern Transvaal. It is most commonly found on savannas or savanna woodlands where it can be found growing on termite mounds.
In heavy soils the termite mounds provide the tree with aerated soil, and a source of moisture, and the roots provide protection for the termites. As they live on dead organic matter the termites don't eat the living wood. Jackalberry wood is almost termite-resistant after it has been cut down.
