Monanthotaxis Bokoli (de Wild. & T.durand) Verdc.

Monanthotaxis bokoli: Overview

Monanthotaxis bokoli, scientifically known as Monanthotaxis bokoli (De Wild. & T.Durand) Verdc., is a flowering plant mainly found in tropical Africa.

Common Names

The plant Monanthotaxis bokoli is known by different names in various regions of Africa. Some of these names include Mufua in Cameroon, Umshwati in Swaziland, and Omuluvale in Uganda.

Appearance

Monanthotaxis bokoli is a small tree or a shrub that can grow up to 10 m tall. The leaves of the plant are simple, alternate, and have a length of around 8 cm and a width of 3.5 cm. The flowers are small, approximately 4 mm in diameter, and have a pale-yellow color.

The plant has a slender trunk that is greyish-brown and is covered with small bumps. This bumpiness is due to the presence of lenticels which are small pores present on the bark of the tree that allow air exchange. The bark of the tree is used for its medicinal properties in some African cultures.

Uses

The plant Monanthotaxis bokoli has various uses in different African cultures. The bark and leaves are used for medicinal purposes to treat various ailments such as gastrointestinal disorders, respiratory problems, and fever.

The wood of the tree is used for fuel, and its fruits have a use in some African cultures as a source of food. The plant also has cultural significance and is used in some traditional ceremonies.

Additionally, the plant is grown as an ornamental tree due to its attractive appearance and small size.

Light Requirements

Monanthotaxis bokoli requires partial shade to grow well. This plant cannot tolerate direct sunlight, which can cause scorching of the leaves and stem. It is best to place the plant in a shaded spot or under a canopy of taller trees.

Temperature Requirements

The plant grows best in warm to hot conditions. The ideal temperature range for optimal growth is between 18-30°C (64-86°F). It is important to avoid extreme temperature fluctuations, as this can cause damage to the plant.

Soil Requirements

Monanthotaxis bokoli prefers well-drained soils that are rich in organic matter. The soil should be kept moist, but never waterlogged. The pH of the soil should be slightly acidic to neutral, ranging from 5.5-7.0. The addition of organic matter such as compost can help improve soil texture, drainage, and fertility.

Cultivation of Monanthotaxis bokoli

Monanthotaxis bokoli can be propagated from seeds or cuttings. For seed propagation, sow seeds in a well-draining potting mix and keep them moist. Germination can take up to six weeks. For cutting propagation, take cuttings from young stems and place them in a well-draining potting mix. Rooting can take up to three months, and it's important to keep the soil moist and to provide humid conditions.

Watering needs of Monanthotaxis bokoli

Monanthotaxis bokoli prefers moist but well-draining soil. Water the plant regularly, keeping the soil slightly damp but not waterlogged. During the growing season, watering once a week is usually enough, but in hotter and drier conditions, more frequent watering may be necessary. During the dormant season, water less frequently, allowing the soil to dry out slightly between waterings.

Fertilization of Monanthotaxis bokoli

Monanthotaxis bokoli doesn't require fertilization, but if you want to encourage growth, you can fertilize sparingly during the growing season with a balanced fertilizer. Be sure to dilute the fertilizer to half strength and to apply it to moist soil.

Pruning of Monanthotaxis bokoli

Monanthotaxis bokoli doesn't require extensive pruning, but occasional trimming can help to shape the plant and encourage fuller growth. Prune back any dead or damaged stems as soon as you notice them. You can also prune back the tips of the stems to encourage bushier growth. Avoid pruning too frequently, as Monanthotaxis bokoli doesn't respond well to heavy pruning.

Propagation of Monanthotaxis bokoli

Monanthotaxis bokoli can be propagated by both sexual and asexual methods. Here are the details:

Sexual Propagation

The plant can be propagated by seeds, which can be collected from the fruit of the mature plant. It is important to ensure that the seeds are ripe before collecting them, as immature seeds may not germinate.

The seeds can be sown in a well-draining soil mix that is moist but not waterlogged. They should be sown at a depth of about one centimeter and covered lightly with soil. The pot should be placed in a warm, bright location, but not in direct sunlight, and kept moist until germination occurs. Germination can take anywhere from a few weeks to a few months.

Asexual Propagation

Monanthotaxis bokoli can also be propagated asexually by stem cuttings. Here are the steps:

1. Take a healthy stem cutting, about 10-15 cm long, from the parent plant.
2. Remove the bottom leaves and cut the stem just below a node.
3. Dip the cut end of the stem in rooting hormone powder.
4. Insert the cutting into a well-draining soil mix, making sure that the node is buried in the soil.
5. Water the cutting and cover it with a plastic bag to maintain humidity.
6. Place the cutting in a warm, bright location, but not in direct sunlight.
7. After a few weeks, check if roots have formed by gently tugging on the cutting. If there is resistance, roots have formed and the plastic bag can be removed.

Once the cutting has formed roots, it can be transplanted into a larger pot or to the garden.

Disease and Pest Management for Monanthotaxis bokoli

Monanthotaxis bokoli, like any other plant, is prone to various diseases and pest infestations that can adversely affect its growth and productivity. Proper management of these infestations is vital in maintaining healthy plants and optimizing yields.

Common Diseases

Some common diseases that affect Monanthotaxis bokoli include:

• Anthracnose: This fungal disease affects the leaves, stems, and fruits of the plant. It is characterized by large, dark, sunken lesions that may cause premature leaf fall, defoliation, and reduced yields. The disease spreads rapidly, especially in wet and humid conditions. To manage anthracnose, ensure adequate air circulation, remove and dispose of infected plant parts, and apply fungicides as per the manufacturer's instructions.
• Cercospora Leaf Spot: This disease causes yellowish-brown spots on the leaves, which may later develop into circular or oblong lesions with gray centers and brown margins. Cercospora leaf spot reduces photosynthesis, limits growth, and may cause defoliation, ultimately reducing yields. To manage this disease, maintain good sanitation, use resistant cultivars, rotate crops, and apply fungicides.
• Root Rot: Root rot is caused by fungi that thrive in poorly drained soils. Symptoms include yellowing of leaves, wilting, stunting, and root discoloration. Infected plants may eventually die if left untreated. To manage root rot, avoid over-watering, water in the mornings, and maintain proper drainage in the soil.

Common Pests

Some common pests that infest Monanthotaxis bokoli include:

• Aphids: Aphids suck sap from the leaves, causing them to curl, stunt and turn yellow. They can also transmit viruses, further weakening the plant. To manage aphids, prune and dispose of infested parts, spray the plant with a strong jet of water, or use insecticidal soap.
• Spider Mites: Spider mites are tiny pests that feed on the leaves, sucking sap, and causing them to turn yellow or brown. Heavy infestations can lead to defoliation and reduced yields. To manage spider mites, maintain adequate humidity, prune and dispose of infested parts, and apply insecticidal soap or acaricides.
• Thrips: Thrips are tiny pests that feed on the leaves, causing white or silvery patches, stunted growth, and deformed flowers. They can also transmit viruses. To manage thrips, prune and dispose of infested parts, use reflective mulch, and apply insecticidal soap or insecticides.

Proper diagnosis and timely intervention are crucial in managing pests and diseases, minimize losses and preserve crop yields.
