Warburgia salutaris (Bertol.f.) Chiov. | |
Warburgia salutaris (pepper-bark tree, Afrikaans : Peperbasboom, Sotho : Molaka, Venda : Mulanga, Zulu : Isibaha) [2] is a species of tree in the family Canellaceae. It is found in eastern and southern African locations e.g. Botswana, Namibia, Kenya, Tanzania, Zambia, Mozambique, South Africa, Eswatini, Malawi and Zimbabwe. It is threatened by habitat loss. It is a popular medicinal plant and is overharvested in the wild, another reason for its endangerment. [3] The Pepper-bark tree is a protected tree in South Africa. [2] Various projects are investigating methods of propagation under controlled conditions with subsequent planting in the wild. [4]
This is an erect tree growing up to about ten metres in maximum height, but known to reach 20 metres at times. It has a thick canopy of aromatic, shiny green leaves. The evergreen leaf blades are lance-shaped, measuring up to 11 cm long by 3 wide. The flowers have ten yellow-green petals. They are each just under a centimeter long and are solitary or borne in small clusters of up to 3. The fruit is a berry, leathery purple or black in color when ripe, measuring up to 4 cm wide.
The leaves are used to add peppery flavoring to food and tea. [4] The bitter taste of the tree's bark and leaves is due to the presence of iridoids. The aromatic, oily, yellowish wood is used for firewood. [4]
This plant is used medicinally by the Maasai people to treat malaria. [5] It is used as a snuff or smoked for respiratory complaints such as common cold and cough. [4] The bark can be purchased at markets in Tanzania, [6] and elsewhere. [7] Moreover, "Dried bark is chewed and the juice swallowed, thus acting as remedy for stomach-ache, constipation, coughs, fever, toothache, muscle pains, weak joints, and general body pains." [8]

The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments and fine furniture. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates.
Pterocarpus angolensis is a species of Pterocarpus native to southern Africa, in Angola, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Democratic Republic of the Congo, Zimbabwe, and Zambia.

It is native to Africa, the Middle East and the Indian subcontinent. It is also considered a 'weed of national significance' and an invasive species of concern in Australia, as well as a noxious weed by the federal government of the United States.
Schinus molle is an evergreen tree that grows to 15 meters. It is native to an area from the Peruvian Andes to southern Brazil.

Warburgia ugandensis, also known as Ugandan greenheart or simply greenheart tree, is a species of evergreen tree native to East Africa. Countries in which the plant species is found include Kenya, Tanzania and Uganda. The wood is resistant to insect attack and very strong. It was commonly used for the yoke pole of ox-wagons, the Disselboom. Early Indian immigrants to Kenya, working on the construction of the railway, used the leaves to flavor their curries before the chilli plant was commonly introduced. The flavor is hot and subtly different from chillies.

The tree itself is fairly hardy, with frost resistance and drought tolerance. The tree, fruit, seed, leaves, and roots are all used for human consumption, medicinally, or for fuel. The trees themselves can also be used as natural land division barriers.
