Entoplocamia Aristulata (hack. & Rendle Ex Scott-elliot) Stapf

Origin and Common Names

Entoplocamia aristulata (Hack. & Rendle ex Scott-Elliot) Stapf is a plant species native to Cameroon, Central Africa.

It is commonly known as "Bakundu Witchcraft Poison" or simply "Bakundu Poison" due to its significant use in the traditional medicine of the Bakundu people, an indigenous group of Cameroon.

Uses

Entoplocamia aristulata is poisonous and has been used for centuries by the Bakundu tribe as a potent killing agent in their traditional hunting and warfare activities. It is still used as a potent poison in Africa today.

The plant's poisonous constituents, aristolochic acids, have been used in modern medicine for their anti-tumor, anti-inflammatory, and antimicrobial activities. Studies have shown that they are effective in treating some forms of cancer.

General Appearance

The Entoplocamia aristulata is a woody climbing vine that grows up to 20 m long. It bears oval-shaped, opposite leaves that have a wavy margin and a pointed apex. The leaves are green, glossy, and up to 18 cm long.

The plant has a bell-shaped flower that is brownish-purple in color and about 3 cm in diameter. The fruit is an oblong capsule that is around 5 cm long and contains many small seeds.

The plant thrives in the tropical rainforests of Central Africa and prefers to grow in well-drained soils that are rich in organic matter. It needs plenty of water and sunlight to grow properly, and it tends to climb on other trees in the forest canopy for support and to reach sunlight.

Light Requirements

Entoplocamia aristulata grows best in partial to full shade conditions. Direct sunlight can scorch the leaves and hinder growth. It is recommended to grow this plant in areas with bright, indirect light to promote healthy growth and development.

Temperature Requirements

This plant thrives in warm and humid conditions. The optimal temperature for Entoplocamia aristulata growth ranges from 20°C to 30°C. It is important to maintain a consistent and moderate temperature to avoid stress on the plant.

Soil Requirements

Entoplocamia aristulata requires well-draining soil with a neutral to slightly acidic pH range of 6.0 to 7.5. The soil should be loamy and rich in organic matter. This plant prefers soil that is consistently moist, but not waterlogged.

Cultivation Methods:

The Entoplocamia aristulata plant is native to tropical Africa and requires a warm and humid climate to grow. It is typically grown as an ornamental plant but can be cultivated for commercial uses as well. The plant is best grown in well-draining soil that is rich in organic matter. The soil pH should be around 6.0 to 7.0. Plant the young plant in the spring or summer, and make sure it is placed in a partially shaded area.

Watering Needs:

The plant needs consistently moist soil to grow correctly, so water it frequently. Do not overwater as this can cause the plant to rot. The plant's soil should not be allowed to dry out completely, and it is better to water the plant deeply rather than frequently. Water the plant more often during the growing season and less during the dormant winter months.

Fertilization:

The Entoplocamia aristulata plant requires regular fertilization to promote growth, flowering, and overall health. Use a general-purpose organic fertilizer that contains a balance of nutrients like nitrogen, phosphorus, and potassium. Add the fertilizer during the growing season, every two weeks or so.

Pruning:

The plant requires minimal pruning as it grows naturally into an attractive shape. However, it can be pruned to maintain a particular shape and size. Prune the plant after the flowering season ends. Remove any dead or damaged branches and pinch off any new growth that is lower than the desired height. Pruning will promote bushier growth and lead to an overall healthier and more attractive plant.

Propagation of Entoplocamia aristulata

Entoplocamia aristulata can be propagated through both sexual and asexual means. The following are the most common methods of propagation:

Seed propagation

Propagation through seeds is the most common method. The seeds of Entoplocamia aristulata are small and black. They must be sown in well-draining soil. The ideal soil pH for successful seed germination is between 4.5-5.5. The seeds require a warm, humid environment to germinate, and they can take up to 2-3 months to sprout. Once the seedlings have developed roots and are big enough to handle, they can be repotted into individual pots.

Cutting propagation

Cutting propagation is another simple method. The cuttings should be taken in the spring from the top growth of the plant. Cuttings can be taken from the tips of the shoots, and they should be around 6 inches long. The leaves should be removed from the lower two-thirds of the stem. The cuttings must be inserted into a pot filled with a mix of sand and peat and should be watered regularly. When roots have developed, the cutting can be detached and transferred to a pot with potting mix.

Air layering propagation

Air layering propagation can also be used for Entoplocamia aristulata. This method involves making a cut into the stem to expose the inner part of the stem. Roots will grow from the exposed area. Once the roots have grown, the branch can be cut off and potted in soil. This method is usually done during the growing season.

Disease Management

Entoplocamia aristulata plant is susceptible to various fungal diseases, including leaf spot, wilt, and stem rot. The best way to prevent fungal diseases is to keep the plant dry by avoiding frequent overhead watering. Ensure that the soil is well-drained, and do not allow water to sit on the leaves for an extended period. Ensure proper air circulation around the plant by maintaining proper spacing between plants.

If you notice signs of fungal diseases on your Entoplocamia aristulata plant, remove affected leaves and stems promptly. Use a fungicide to treat the plant according to the instructions on the package. Avoid planting susceptible plant species near the Entoplocamia aristulata plant, as the diseases can spread quickly.

Pest Management

Entoplocamia aristulata is generally pest-free, but it can attract mealybugs and spider mites. Mealybugs are usually white and waxy insects that suck sap from the plant and cause yellowing and wilting. Spider mites, on the other hand, are small and difficult to see with the naked eye. They damage the plant by piercing plant tissue and sucking out the sap.

If you notice an infestation of mealybugs or spider mites, isolate the plant immediately to prevent the spread of the pests. Use a stream of water to knock off the pests from the plant and apply insecticidal soap according to the instructions on the package. You can also use neem oil to repel the pests and prevent reinfestation.
