Introduction
Annona senegalensis is a multi-stemmed, deciduous African fruit tree that is found in semi-arid to subhumid areas. It has a long history of traditional use and has also been used as food and food additives.
Description
Description
Annona senegalensis is a shrub or small deciduous tree, 2–6 up to 11 m tall, usually multi-stemmed. Bark is grey-silver, smooth to cracked with age; small branches are hairy, which become smooth as they mature. The leaves are simple, oblong to ovate, ranging from 60–180 x 25–115 mm, bluish-green with few hairs on the upper surface, pale-bluish with dense hairs below, especially when young; short and thick petioles; smooth leaf margins; alternating leaves with rounded apex and base.
Flowers occur in spring to early summer, from October to December, usually small and fleshy, about 30 mm in diameter, with pale yellow petals and 3 sepals that are free and smaller than the petals. Flowers are axillary, solitary or in groups of 2–5 on about 20 mm long stalks. The fruit is fleshy, amber, lumpy, egg-shaped, about 40 mm in diameter, and indehiscent.
Conservation Status
Status
Annona senegalensis is not endangered; it is assessed as Least Concern (LC) on the Red List of South African Plants.
Distribution and habitat
Distribution description
Annona senegalensis is a woodland species that can be found in its natural state from West to East Africa in the tropical and subtropical zones as well as on coastal sands, on islands in the western Indian Ocean, in tropical east and northeast, west and west-central Africa, and in southern subtropical Africa. In South Africa it can be found along rivers, in woodlands, on rocky outcrops and in swamp forests in KwaZulu-Natal, Limpopo and Mpumalanga provinces.
Derivation of name and historical aspects
History
The genus name Annona is a Latin word annona, which means ‘yearly produce’, referring to the way in which species in this genus produce their fruits. The species name senegalensis, means ‘of Senegal’, the nation in West Africa where the type specimen was found.
Ecology
Ecology
Annona senegalensis flowers are pollinated by various species of beetle, hand pollination can also be practiced when grown as a crop. The plants in their natural habitat prefer a sunny or semi-shaded position. The leaves and shoots are browsed by game such as Kudu and Giraffes. The fruits are eaten by birds, monkeys, baboons, kudu, bush pigs and porcupines, and are susceptible to damage by insects. Seeds lose viability within 6 months, but their viability can be maintained for over 2 years in air-dry storage at 5°C.
Uses
Use
Different parts of the plant have various uses. Leaves, flowers, and fruits are edible. The leaves are used to treat smallpox, TB and yellow fever. The bark has been used to treat hernias and snakebite. The root is used traditionally to treat viral infections, gastritis, male sexual impotence, erectile dysfunction, dizziness and snake bites. In addition, the root also works well for infectious infections. It is also possible to treat chicken pox using the tree's juice. Malaria has been treated with Annona senegalensis in Guinea. The bark is also used in Eswatini to heal open wounds. The wood is soft and white, and is used for building huts and to make handles for utensils.
In Mozambique, children are fed the roots to promote forgetfulness of their mother’s milk. The roots can also be mixed with Trema orientalis to make a strong emetic. Flowers are used in cooking. Livestock feed on the leaves and humans eat the leaves as a vegetable. The fruit is edible with a pleasant pineapple-like aroma. Anonna senegalensis has also been used to manage pests in Tanzania and Nigeria. In the Republic of Benin, the fresh leaves are placed inside poultry buildings to dry out. By so doing, it will get rid of parasites like fleas and lice. This is done once or twice a week.
Growing Annona senegalensis
Grow
Annona senegalensis is fast and simple to propagate through seeds. The seeds are sowed immediately after harvesting, in a well-drained medium (loamy soil), thereafter kept in a warm and moist environment. The seeds will start germinating within 2 to 4 weeks. Fertilizer should be applied after transplanting the seedlings into bags to stimulate growth. It can also be propagated through seeds falling to the ground after disintegration of the fruit. In the wild, germination is good in recently cultivated or burned areas.
