Botanical Name : Schinziophyton rautanenii
Hutch. ex Radcl.-Sm.
Species: S. rautanenii
Common Names:Mongongo nut, Feather weight tree, Manketti Tree
Habitat :The Schinziophyton rautanenii is distributed widely throughout southern Africa. There are several distinct belts of distribution, the largest of which reaches from northern Namibia into northern Botswana, south-western Zambia and western Zimbabwe. Another belt is found in eastern Malawi, and yet another in eastern Mozambique.
The manketti tree prefers hot and dry climates with low amounts of rain. It also prefers to grow in wooded hills and sand dunes.
Its habitat is dotted with trees and does not receive enough rain to be considered a prairie. The countries that lie in this biome are Mauritania, Guinea, Liberia, Ethiopia, Sudan, Chad, Mali, Niger and Uganda.
Schinziophyton rautanenii is a deciduous tree.It has a large, straight trunk with stubby and contorted branches and a large spreading crown. It has an upright manner of growth and is about 49 to 66 feet (15 to 20) meters tall. The leaves are a distinctive hand shape and are compound. The leaflet is a wide lance to an egg shape. They are composed of seven leaflets that are carried on hairy stalks that are up to 6 inches (15 cm) in length. The leaves are about 6 inches (15 cm) long and both sides are dark green in color. They are covered in fine hairs and are arranged alternately on branches.
The flowers are somewhat oval in shape, and are about 1 1/4 inch (3.5 cm) long, 3/4 inch (2.5 cm) wide, and are about 1/2 inch (10 mm) in diameter. They flower in early summer. The whitish flowers are carried in slender loose spays.
Leaves alternate, digitately compound, consisting of 5-7 leathery segments usually hairless below and with grey wooly hairs above. There are usually 1 or 2 black glands on the upper side of each leaf-stalk.
Flowers whitish or yellow, dioecious, in loose rusty sprays. Male flowers in long rusty sprays, female shorter in length.
Fruit ovoid, waxy and brown in colour; weighing 7-10 g with a thick leathery skin, fleshy, dry, spongy pulp 2-5 mm thick, shell tough 3-7 mm thick.
Seeds 1 or 2 in the fruit.
The taproot on the tree goes down until it reaches water. In this case, it is long because it is located in the savanna. The lateral root is very small.
So popular are the fruit and nuts of the mongongo tree that they have even been described as a “staple diet” in some areas, most notably amongst the San bushmen of northern Botswana and Namibia. Archaeological evidence has shown that they have been consumed amongst San communities for over 7,000 years. Their popularity stems in part from their flavour, and in part from the fact that they store well, and remain edible for much of the year.
The fruit is edible and can be eaten fresh, dried or cooked and have a pleasant taste likened to that of plums. The fruit retains its flavour even when dry.
Dry fruits are first steamed to soften the skins. After peeling, the fruits are then cooked in water until the maroon-coloured flesh separates from the hard inner nuts. The pulp is eaten, and the nuts are saved to be roasted later. Alternatively, nuts are collected from elephant dung; the hard nut survives intact through the digestive process and the elephant does the hard work of collecting the nuts. During roasting of the nuts, direct contact with the fire is avoided, using sand to distribute the heat evenly. Once dry, the outer shell cracks easily, revealing the nut, encased within a soft, inner shell. The nuts are either eaten straight, or pounded as ingredients in other dishes.
. The fruit is normally skinned after steaming in a pot with little water, then boiled in fresh water to separate the nuts. The fruit is used in making aromatic soups and sweet porridge, they can be dried and consumed as sweetmeats. During roasting direct contact of seeds with the fire coals is avoided by roasting in a sand heap. Fruit carbohydrate content is between 65-77%, fibre 2.5-3%, crude protein 6-9% and Ca levels are 85-100 mg/ 100 g. In the abscence of moisture fruits can remain edible for up to 8 months if left on ground where they fall.
The fruit pulp is fermented to give a refreshing potent beer, distilled for alcohol.
Per 100 grams shelled nuts:
*57 g fat:
*24 g protein
*193 mg calcium
*527 mg magnesium
*4 mg zinc
*2.8 mg copper
*565 mg vitamin E (and tocopherol)
The roots are used as a remedy for stomach pains and diarrhea, the nuts tied around the ankles are said to relieve leg pains.
The oil from the nuts has also been traditionally used as a body rub in the dry winter months, to clean and moisten the skin, while the hard, outer nut-shells are popular as divining “bones”. The wood, being both strong and light, makes excellent fishing floats, toys, insulating material and drawing boards. More recently, it has been used to make dart-boards and packing cases.
The plant has potential use in desert encroachment prevention and sand dune stabilization. Its hardiness makes it ideal for arid land reclamation.
Erosion control: S. rautanenii roots protect sandy soils from wind and water erosion.
Fruit enjoyed by both cattle and game. Fruit pulp and the seed meal which is very rich in protein was fed to cattle up to 1962, however this feed is suspected to cause a discolouration of beef. Elephants feed on the bark.
Truncheon-cuttings used for fencing around homes in southern Angola. In some places the tree is highly held culturally and venerable.
Offers shade in hot areas e.g. in the Kalahari desert.
Known Hazards: : Toxicological results suggest a tenous link between oil use and goitre.
