Origin and Common Names
The plant Dichapetalum angolense Chodat var. leucanthum Pellegr. is a member of the Dichapetalaceae family, which is native to southern and central Africa. It is commonly known as "muanga" in the Democratic Republic of the Congo, where it is mostly found, but it is also called "ciha" in Tanzania and "mutongololo" in Zambia.
Uses
The plant has significant medicinal uses, especially in the treatment of snakebites and African trypanosomiasis (also known as sleeping sickness). The stem and root bark contain a compound called dichapetalin, which has potent toxic effects on animals and humans, but when used in controlled doses, it can be effective in neutralizing venoms from various snake species. Additionally, the leaves have been found to have antimicrobial properties due to the presence of alkaloids.
General Appearance
Dichapetalum angolense Chodat var. leucanthum Pellegr. is a small evergreen shrub that grows up to 1.5 m in height. It has a woody stem with smooth, greyish-brown bark and short, thorny branches. The leaves are simple, alternate, leathery, and dark green in color, with a glossy surface and slightly curved margins. The flowers are small, white, and arranged in clusters, blooming from May to July. The fruit is a capsule that contains four to six seeds, which are black, shiny, and slightly flattened.
Light Requirements
Dichapetalum angolense Chodat var. leucanthum Pellegr. thrives in areas with full sun exposure. It needs at least six hours of direct sunlight daily to support healthy growth. Insufficient light may cause stunted growth and affect flowering abilities.
Temperature Requirements
This plant species prefers warm temperatures ranging from 20 to 30 degrees Celsius. Temperatures below 15 degrees Celsius may slow down or halt growth. Dichapetalum angolense Chodat var. leucanthum Pellegr. can tolerate brief temperature drops and hot periods, but maintaining a consistent temperature is ideal.
Soil Requirements
The plant needs well-draining soils rich in organic matter with a slightly acidic to neutral pH level, ranging from 5.5 to 7. Soil fertility does not significantly impact growth. However, regular application of organic matter can boost nutrient levels and improve the soil structure. Additionally, wet or waterlogged soils may cause rotting and damage the roots, leading to poor growth and death.
Cultivation methods
Dichapetalum angolense Chodat var. leucanthum Pellegr. is a tropical plant that thrives in warm and humid conditions. It requires well-draining soil and full to partial sun exposure. When planting, it is essential to provide adequate space for growth and good air circulation.
Watering needs
Proper watering is crucial to the successful cultivation of Dichapetalum angolense Chodat var. leucanthum Pellegr. It requires moist soil but not waterlogged. The watering frequency depends on the soil drainage and the weather condition. During the hot and dry season, the plant may require frequent watering to keep the soil moist. However, during the rainy season, reduce water frequency to avoid root rot.
Fertilization
Regular fertilization is necessary to provide the necessary nutrients for growth. Dichapetalum angolense Chodat var. leucanthum Pellegr. responds well to a balanced fertilizer application. A complete fertilizer with a nitrogen-phosphorus-potassium ratio of 10-10-10 or 12-12-12 can be applied every four to six weeks during the growing season. Always follow the manufacturer's instructions for optimal results.
Pruning
Pruning helps maintain the plant's health and shape. Dichapetalum angolense Chodat var. leucanthum Pellegr. may require pruning to remove dead or diseased parts, improve air circulation, or promote branching. Pruning helps redirect the plant's energy to the healthier parts, promoting vigorous growth. Use clean and sharp pruning tools to prevent the spread of diseases, and always sanitize the tools before use.
Propagation of Dichapetalum angolense Chodat var. leucanthum Pellegr.
Dichapetalum angolense Chodat var. leucanthum Pellegr., commonly known as "poison rope," is a flowering plant species that belongs to the Dichapetalaceae family. The plant is native to Africa, specifically in Angola, Gabon, and the Congo. The plant's propagation can be done through several methods.
Seeds
The most common way to propagate Dichapetalum angolense Chodat var. leucanthum Pellegr. is through seeds. Fresh seeds can be collected from the plant during the fruiting season. The seeds can be sown in trays or pots filled with a well-draining potting mix. Cover the seeds with a thin layer of soil, and water them lightly. Keep the soil moist and place the tray or pot in a warm and bright location. The seeds will germinate in 2-3 weeks.
Cuttings
Propagation of Dichapetalum angolense Chodat var. leucanthum Pellegr. can also be done through stem cuttings. Take stem cuttings from healthy plants during the growing season. Cut a 6-inch length from a healthy stem, just below a node. Remove the leaves from the lower half of the stem, leaving two or three leaves on the upper half. Dip the cut end in rooting hormone powder to stimulate root growth. Plant the cutting in well-draining potting mix. Water lightly and place it in a warm and bright location. The cutting will root in 3-4 weeks.
Division
Division is another propagation method for Dichapetalum angolense Chodat var. leucanthum Pellegr. Plants that have formed clumps can be divided into smaller sections. Carefully dig up the clump and separate it into smaller sections, each with a few roots and shoots. Plant each section in a pot or directly in the ground in a well-draining potting mix. Water lightly and place it in a warm and bright location. The plant will establish in a few weeks.
