It is a shrub that grows up to a height of 4 meters, with green branches and alternate, oddly pinnate leaves. This plant is endemic to Wollo in Ethiopia and plays an essential role in local culture and ecology.
Common Names:
Millettia stapfiana is known by numerous names, including Tikitik, Tej Tara, and Liben Berber in Amharic and Welmeleri in the local Wollo language.
Origin:
This species is native to the Wollo highlands in northern Ethiopia, growing on the rocky and open hillsides near the Liben Plateau. It thrives in the dry and arid regions, where it endures long periods of drought. Millettia stapfiana is endemic to Ethiopia and is not found anywhere else in the world.

The leaves, bark, and roots of Millettia stapfiana are used for a wide variety of purposes. The bark serves as a source of fiber, while the roots are boiled and consumed as a remedy for various ailments, including diarrhea and dysentery. The leaves are used as animal fodder and play a crucial role in conserving soil nutrients and preventing erosion. The plant is also an excellent source of firewood, charcoal, and timber for building.
General Appearance:
Millettia stapfiana is a deciduous woody shrub that grows up to 4 meters tall. The stem is green, and the bark is smooth, light brown to dark brown in color, and exfoliates regularly. The leaves are alternate, oddly pinnate, with 5-7 leaflets, and are around 15-25 centimeters long. The inflorescence is in the form of axillary and terminal racemes, and the flowers are reddish-purple in color and fragrant. The fruit is a linear-oblong pod, around 15-25 centimeters long, and contains several seeds.
Light Conditions
The Millettia stapfiana Dunn plant typically thrives in moderate to high light conditions, which includes exposure to both natural and artificial lighting. However, this plant can also grow in partial shade. It is essential to avoid exposing the plant to direct sunlight for a prolonged period since it can damage its leaves.
Temperature
The ideal temperature conditions for the Millettia stapfiana Dunn plant range from 20°C to 30°C. This plant can also tolerate temperature fluctuations, but it can be damaged if the temperature drops below 15°C or exceeds 35°C for an extended period. Therefore, during the colder seasons, it is essential to keep the plant in a warm environment to avoid any damage or slowing down of its growth rate.
Soil Requirements
The Millettia stapfiana Dunn plant grows well in well-draining soils, which consist of equal portions of sand, loam, and peat moss. The soil's pH should be in the slightly acidic to neutral range, with a pH of 6.0 to 7.0. It is essential to ensure that the soil remains moist but not waterlogged to prevent the roots from rotting. Adding organic matter to the soil can help improve the soil structure and provide the plant with essential nutrients.
Cultivation methods
Millettia stapfiana, also known as the Hairy-stemmed wisteria, typically grows in hot and humid climates that receive a lot of rainfall. The plant thrives in well-drained soil with a pH range between 5.5 and 6.5. It prefers full sun and can tolerate partial shade. The plant can be propagated through seeds or stem cuttings.
Watering needs
Millettia stapfiana requires regular watering, especially in dry seasons, to maintain healthy growth. Young plants need more frequent watering than mature ones. The soil should be moist but not saturated with water. Overwatering can lead to root rot and other plant diseases.
Fertilization
To promote healthy growth, Millettia stapfiana requires regular fertilization with a balanced fertilizer. During the growing season, apply a complete fertilizer every four to six weeks. Follow the manufacturer's instructions for application rates and frequency. Avoid applying too much fertilizer as it can damage the plant.
Pruning
Pruning Millettia stapfiana should be done in the winter when the plant is dormant. Remove any dead, diseased or damaged wood. Cut back any overgrown branches and maintain the plant's shape. Prune lightly as the plant flowers on the old wood. Avoid heavy pruning, which can reduce flowering and lead to stunted growth.
Propagation of Millettia stapfiana Dunn
Millettia stapfiana Dunn, commonly known as African oak, is a tree species native to the tropical regions of Africa. Propagation of this plant can be accomplished through various methods:
Seed Propagation
Propagation through seeds is the most common method of growing Millettia stapfiana Dunn. Mature seeds are collected from the tree during the fruiting season, usually in the months of September to November. The seeds should be soaked in water for about 24 hours before sowing to improve germination. The seeds can be sown in individual containers or in a seedbed with well-draining soil. The seedlings can be transplanted into larger containers or directly into the ground once they have developed enough roots.
Cutting Propagation
Cutting propagation is another method of growing Millettia stapfiana Dunn. Hardwood cuttings taken from the tree during the dormant season, usually in January to February, can be used for propagation. The cuttings should be treated with rooting hormone to stimulate root growth. The cuttings can be planted in a rooting medium consisting of sand, peat moss, and perlite. The rooting medium should be kept moist and warm, and the cuttings should be shielded from direct sunlight until they develop roots. The rooted cuttings can then be transplanted into larger containers or directly into the ground.
Air Layering
Air layering is a propagation method that involves inducing roots to grow on a branch while it is still attached to the parent plant. This method can be used for Millettia stapfiana Dunn, but it is less commonly used. A ring of bark is removed from the selected branch, and the exposed area is treated with rooting hormone. The area is then covered with moist sphagnum moss and wrapped with plastic to maintain humidity. Once roots have formed, the branch can be cut off and planted in soil.
Disease and Pest Management for Millettia stapfiana Dunn
Millettia stapfiana Dunn, also known as Rhodesian teak, is a hardwood tree commonly found in Africa. While it is generally a hardy plant, it is susceptible to certain diseases and pests that can damage or even kill the tree if not managed properly.
Common Diseases
One of the most common diseases that affects Millettia stapfiana is root rot. This is caused by a fungus that thrives in wet soil conditions and can cause the roots of the tree to decay. To prevent this, it is essential to ensure that the plant is not overwatered and that any excess water drains away quickly. If root rot is detected, the infected roots should be pruned and fungicides can be used to treat the remaining healthy roots. Another disease that can affect the tree is leaf spot, which is caused by various fungi and can be treated with fungicides as well.
Common Pests
One of the most damaging pests that can affect Millettia stapfiana is the stem borer. The larvae of this moth can bore into the trunk of the tree, causing significant damage. To prevent stem borers, it is important to keep the tree healthy and free of wounds, as well as removing any nearby infested trees. Another common pest is the mealybug, a small white insect that feeds on the sap of the tree and can weaken it over time. Mealybugs can be treated with insecticides, or by releasing natural predators such as ladybugs or lacewings.
Integrated Management
The best approach to managing diseases and pests for Millettia stapfiana is through integrated pest management. This involves a combination of preventative measures, chemical treatments and biological controls. Key preventative measures include proper watering, fertilization, pruning and mulching to keep the tree healthy and reduce stress. Regular inspections of the tree can help detect any signs of disease or pests early on, allowing for prompt treatment. Awareness of environmental conditions such as humidity and temperature changes can also help in predicting potential pests attack which will enable early implementation of the management measures before the problem spreads around the plant.
When it comes to chemical treatments, it is important to use pesticides and fungicides that are safe for the tree, as well as the surrounding environment. Avoid using harmful chemicals if there are alternative and less hazardous options that can be used. Biological controls such as releasing natural predators or planting companion plants that repel pests are also effective ways of managing pests without having to resort to chemicals.
Overall, with proper disease and pest management, Millettia stapfiana can thrive and provide many years of beauty and enjoyment.
